American Academy Of Sleep Medicine Issues Updated Central Sleep Apnea Treatment Guidelines

Table of Contents

Detroit, Michigan – A Revised clinical practice guideline, developed by a task force from the American Academy of Sleep Medicine, provides new recommendations for managing central sleep apnea, a condition where the brain fails to signal the body to breathe regularly during sleep. The Updated guidance, available online and slated for publication in the Journal of Clinical Sleep Medicine in December, builds on prior AASM parameters from 2012 and 2016, incorporating recent research on adaptive servo ventilation and the novel therapy of transvenous phrenic nerve stimulation.

Understanding Central Sleep Apnea

Central Sleep Apnea is a distinct form of sleep-disordered breathing, unlike the more common obstructive sleep apnea. It’s characterized by a disruption in respiratory effort, leading to reduced or stopped airflow. This instability is frequently linked to underlying health issues such as Heart Failure, Opioid use and in some cases, even existing Obstructive Sleep Apnea.

“Central Sleep apnea is a Complex form of sleep-disordered breathing that requires individualized, patient-centered care,” stated Dr. M.Safwan Badr, lead author, chair of the AASM task force, and chair of the department of internal medicine at Wayne State University School of Medicine. “It is indeed essential for the treating clinician to prioritize improvements in quality of life and functional outcomes rather than focusing exclusively on the elimination of disordered breathing events.”

Key Recommendations & Treatment Options

All nine clinical recommendations within the guideline are classified as “conditional,” emphasizing the need for clinicians to leverage their judgment alongside individual patient values and preferences when determining the optimal course of treatment. The guideline supports six key treatment approaches for varying causes of central sleep apnea:

Treatment Option Suitable For Notes
Continuous Positive Airway Pressure (CPAP) Various Etiologies May be effective, but not always the first choice.
Bilevel positive Airway Pressure (BiPAP) with Backup Rate Various Etiologies Provides more support than CPAP.
Adaptive Servo Ventilation (ASV) Multiple Etiologies Use with caution in heart failure patients (see below).
Low-Flow Oxygen Specific Cases Can be beneficial in certain circumstances.
Oral Acetazolamide High-Altitude Central Sleep Apnea Used to promote breathing.
Transvenous Phrenic Nerve Stimulation Primary or Heart Failure-Related Central Sleep Apnea Invasive; consider other options first.

Did You No? Central sleep apnea is often misdiagnosed as obstructive sleep apnea, highlighting the need for comprehensive sleep studies.

Adaptive servo ventilation & Heart Failure

While Adaptive servo Ventilation (ASV) received a conditional suggestion, the guideline stresses careful consideration for patients with Heart Failure and reduced ejection fraction. Recent studies have raised concerns about potential adverse effects in this population,leading to a recommendation for ASV treatment to be limited to experienced centers with robust monitoring and follow-up protocols.

Transvenous Phrenic Nerve Stimulation: A New Option

The guideline introduces a new conditional recommendation for Transvenous Phrenic Nerve Stimulation – a device approved by the Food and Drug Management in 2017 for moderate to severe central sleep apnea. This implantable device continuously monitors and stabilizes breathing. However, due to its invasive nature, limited access, and significant cost, the guideline suggests exploring other treatments first.

Pro Tip: If you suspect you have central sleep apnea, consult with a board-certified sleep specialist for accurate diagnosis and personalized treatment.

Guideline Progress & Endorsements

The AASM commissioned a task force of sleep medicine physicians to develop the guideline, based on a systematic literature review and GRADE assessment, considering the certainty of evidence, benefits, risks, patient preferences, and resource utilization.The draft was publicly reviewed, and the final recommendations were approved by the AASM board of directors.

The guideline has been endorsed by numerous organizations including the Alliance of Sleep Apnea Partners, the American Association for Respiratory Care, and the European Respiratory Society.

Long-Term Management of Central Sleep Apnea

effective management of central sleep apnea extends beyond initial treatment. Regular follow-up appointments with a sleep specialist are essential to monitor treatment effectiveness, adjust settings as needed, and address any emerging concerns. Lifestyle modifications, such as avoiding alcohol and sedatives before bed, can also play a supportive role.

Ongoing research continues to refine our understanding of central sleep apnea and identify new therapeutic targets. new technologies and approaches are constantly being evaluated, offering hope for improved outcomes for patients with this challenging condition.

What are the key differences in treatment approaches between CSR-CSA and idiopathic CSA, according to the updated guidelines?

Updated Clinical Practice Guidelines for Treating Central Sleep Apnea: Enhanced Recommendations and Strategies

Understanding Central Sleep Apnea (CSA) & Guideline Updates

Central Sleep Apnea (CSA) is a serious sleep disorder characterized by the cessation of breathing during sleep, not due to airway obstruction (as in Obstructive Sleep Apnea – OSA), but rather a failure of the brain to signal the muscles that control breathing. Recent updates to clinical practice guidelines, primarily from the American Academy of Sleep Medicine (AASM) and informed by ongoing research, reflect a more nuanced understanding of CSA subtypes and thier optimal management. these revisions aim to improve diagnostic accuracy and treatment efficacy for this frequently enough-underdiagnosed condition. Key search terms include: central sleep apnea treatment, CSA guidelines, sleep apnea types, sleep disordered breathing.

Diagnostic Refinements: Identifying CSA Subtypes

Accurate diagnosis is paramount.The updated guidelines emphasize differentiating between CSA subtypes:

* Idiopathic Central Sleep Apnea: No identifiable underlying cause.

* Cheyne-Stokes Breathing (CSR-CSA): Frequently enough associated with heart failure and neurological conditions. Characterized by a cyclical pattern of increasing and decreasing breathing effort.

* High-altitude Periodic Breathing: Occurs at high altitudes due to changes in oxygen levels.

* Treatment-Emergent Central Sleep Apnea (TE-CSA): Develops after initiating treatment for OSA, notably with CPAP.

* Central Sleep Apnea with Complex Sleep Apnea: A combination of both obstructive and central apnea events.

Improved polysomnography (PSG) interpretation, including detailed analysis of respiratory effort and cardiac rhythm, is crucial. The use of auto-titrating positive airway pressure (APAP) devices with central apnea detection capabilities is also increasingly recommended for initial assessment. Sleep study interpretation, polysomnography, apnea-hypopnea index (AHI) are important related terms.

First-Line Treatments: Adapting to Subtype & severity

Treatment strategies are now more tailored to the specific CSA subtype and the patient’s overall health.

* Adaptive Servo-Ventilation (ASV): Remains the gold standard for CSR-CSA, particularly in patients with heart failure. ASV dynamically adjusts ventilation to stabilize breathing patterns.

* CPAP/BiPAP: While CPAP can induce TE-CSA, it remains appropriate for some CSA patients, especially those with mild cases or co-existing OSA. BiPAP might potentially be considered if CPAP is not tolerated.

* supplemental Oxygen: Can be beneficial for high-altitude periodic breathing and some cases of idiopathic CSA, but its use should be carefully monitored.

* Pharmacological Interventions: Acetazolamide can be effective for high-altitude periodic breathing. Other medications, like theophylline, have limited evidence and potential side effects. ASV therapy, BiPAP for CSA, oxygen therapy, sleep apnea medications are key search phrases.

Managing Treatment-Emergent Central Sleep Apnea (TE-CSA)

TE-CSA is a meaningful clinical challenge. The updated guidelines recommend:

  1. CPAP/BiPAP Titration: Optimizing pressure settings to minimize central apneas.
  2. Switching to ASV: If TE-CSA persists despite optimized CPAP/BiPAP.
  3. Consideration of Humidification: Adequate humidification can improve CPAP tolerance and potentially reduce TE-CSA.
  4. Careful Monitoring: Regular follow-up to assess treatment effectiveness and adjust therapy as needed. TE-CSA management, CPAP induced central apnea, sleep apnea device settings are relevant keywords.

addressing CSA in Patients with Heart Failure

the link between CSA and heart failure is well-established. The guidelines now strongly recommend:

* Cardiac Evaluation: Comprehensive assessment of cardiac function in all CSA patients, particularly those with CSR-CSA.

* Optimizing Heart failure Management: Addressing underlying heart failure with appropriate medications and lifestyle modifications.

* ASV as First-Line Therapy: For CSR-CSA,ASV is prioritized to improve both respiratory and cardiac outcomes. Studies have shown ASV can reduce mortality in heart failure patients with CSR-CSA. CSA and heart failure,cardiac sleep apnea,ASV and cardiac outcomes are important search terms.

neurological Considerations & CSA

CSA can also be associated with neurological conditions like stroke and neurodegenerative diseases.

* Neurological Assessment: Patients with suspected neurological CSA require a thorough neurological evaluation.

* Identifying Underlying Cause: Determining the specific neurological factor contributing to CSA is crucial for targeted treatment.

* Multidisciplinary Approach: Collaboration between sleep specialists and neurologists is essential. Neurological sleep apnea, stroke and sleep apnea, neurodegenerative disease and CSA are relevant keywords.

benefits of Adhering to Updated Guidelines

Following the updated clinical practice guidelines for CSA offers several benefits:

* Improved Diagnostic Accuracy: Leading to more appropriate treatment selection.

* Enhanced Treatment Efficacy: Optimizing therapy for specific CSA subtypes.

* Reduced Cardiovascular Risk: Particularly in patients with CSR-CSA and heart failure.

* Better Quality of Life:

TRPM3 & Heat: How Your Body Senses Temperature

by Sophie Lin - Technology Editor
written by Sophie Lin - Technology Editor

Unlocking the Body’s Inner Thermostat: How New Heat Sensor Research Could Revolutionize Pain Management

Imagine a future where chronic pain isn’t managed with potentially addictive opioids, but with targeted therapies that fine-tune your body’s own heat-sensing mechanisms. That future may be closer than we think. Researchers at Northwestern University have, for the first time, visualized the intricate workings of TRPM3, a key protein responsible for detecting temperature, revealing a surprising detail: it senses heat from within the cell, not just at its surface. This discovery isn’t just a win for basic science; it’s a potential game-changer for treating pain, inflammation, and even neurological disorders.

The Unexpected Location of Heat Detection

For years, scientists believed that temperature sensors like TRPM3 functioned primarily at the cell membrane, reacting to external temperature changes. However, the new study, published in Nature Structural & Molecular Biology, demonstrates that the crucial heat-sensing action occurs within the protein itself. Using cutting-edge cryo-electron microscopy (cryo-EM) and electrophysiology, the team created detailed 3D images of TRPM3 in both active and inactive states. This allowed them to pinpoint the internal “switch” that triggers a response to rising temperatures.

“This is a fundamental shift in our understanding of how the body perceives temperature,” explains Juan Du, co-lead author of the study and professor of molecular biosciences at Northwestern. “Knowing that the internal regions of TRPM3 are key to its function opens up entirely new avenues for therapeutic intervention.”

TRPM3: More Than Just a Heat Sensor

While initially identified as a heat sensor, TRPM3’s role extends far beyond simply detecting warmth. It’s intricately linked to several critical bodily functions, making it a promising target for a range of conditions.

Expert Insight: “TRPM3 isn’t just about feeling hot or cold. It’s a crucial player in inflammation, itch, and even the development of epilepsy. Its widespread involvement makes it a particularly attractive target for drug development.” – Wei Lü, co-lead author of the study.

Here’s a breakdown of TRPM3’s diverse roles:

  • Pain Management: Overactivity of TRPM3 is associated with chronic pain conditions.
  • Inflammation: TRPM3 contributes to inflammatory responses in the body.
  • Neurological Disorders: Its involvement in epilepsy suggests potential therapeutic applications for neurological conditions.

The Molecular Switch: How TRPM3 Works

The research team discovered that TRPM3 functions like a molecular switch composed of four interconnected parts. When these parts are tightly bound, the sensor remains inactive. Heat, or certain chemical activators, disrupt these connections, flipping the switch to the “on” position and triggering a flow of ions that signal the brain. Interestingly, the team found that both heat and chemical activators affect the switch in a similar way.

“It’s like a lock and key, but instead of a key physically fitting into a lock, heat or a chemical signal causes a conformational change within the protein itself, unlocking the channel,” explains Sushant Kumar, the study’s lead author.

Did you know? Cryo-EM, the technique used in this study, involves flash-freezing proteins and then bombarding them with electrons to create incredibly detailed images. This allows scientists to visualize structures at near-atomic resolution, something previously impossible.

Future Implications: Targeted Pain Relief and Beyond

The implications of this research are far-reaching. The ability to manipulate TRPM3 activity could lead to the development of non-addictive pain treatments that specifically target the source of discomfort. Instead of broadly affecting the nervous system like opioids, these therapies could fine-tune the body’s natural temperature-sensing mechanisms.

But the potential doesn’t stop there. Researchers are exploring the possibility of using TRPM3 modulation to treat inflammatory diseases and even neurological disorders like epilepsy. The key lies in finding compounds that can selectively activate or deactivate the protein, depending on the desired therapeutic effect.

The Rise of Precision Medicine for Pain

This discovery aligns with the growing trend towards precision medicine, where treatments are tailored to an individual’s unique genetic and molecular profile. Understanding how TRPM3 functions in different individuals could allow doctors to prescribe the most effective pain relief strategies based on their specific needs.

Pro Tip: Keep an eye on developments in cryo-EM technology. As this technology continues to improve, we can expect even more breakthroughs in our understanding of complex biological processes.

Beyond Pain: TRPM3 and Skin Health

Emerging research suggests TRPM3 also plays a role in skin health, particularly in maintaining the skin barrier function. Dysfunction of TRPM3 could contribute to conditions like eczema and psoriasis. This opens up the possibility of developing topical treatments that target TRPM3 to improve skin health and reduce inflammation. See our guide on dermatological advancements for more information.

Frequently Asked Questions

What is TRPM3?

TRPM3 is a protein that acts as a heat sensor in the body. It’s found in sensory neurons and the brain and plays a role in detecting temperature, pain, inflammation, and neurological function.

How does this research differ from previous studies?

Previous research assumed TRPM3 sensed heat at the cell membrane. This study reveals that the key heat-sensing action occurs within the protein itself, a significant shift in understanding.

When might we see new treatments based on this research?

While it’s difficult to predict a specific timeline, the discovery provides a strong foundation for developing new therapies. Preclinical studies are likely to begin soon, and clinical trials could follow within several years.

Is TRPM3 the only heat sensor in the body?

No, TRPM3 is one of several heat sensors. However, it’s a particularly important one due to its involvement in multiple bodily functions and its potential as a therapeutic target.

The Northwestern University study represents a significant leap forward in our understanding of how the body senses temperature. By unlocking the secrets of TRPM3, scientists are paving the way for a new era of targeted therapies that could alleviate suffering and improve the lives of millions.

Unmasking the Nervous System’s Role in Driving Gastrointestinal Cancer Growth

by Dr. Priya Deshmukh - Senior Editor, Health
written by Dr. Priya Deshmukh - Senior Editor, Health


Migraine Drugs Show Promise in Blocking Tumor Growth, Australian Study Finds

Melbourne, Australia – Researchers in Australia have pinpointed key components of the nervous system that appear to fuel the growth of gastrointestinal cancers, potentially opening the door to a novel treatment approach. The finding centers around the possibility of repurposing existing migraine medications to combat these deadly diseases.

The Gut’s ‘Second Brain’ and Cancer growth

Table of Contents

The digestive system harbors its own complex nervous network, often referred to as the “second brain”. This system utilizes signaling molecules called neuropeptides to communicate and influence various bodily functions. Scientists have now discovered that one specific neuropeptide, CGRP, alongside its receptor RAMP1, plays a important role in fostering tumor advancement in colorectal and stomach cancers.

A Breakthrough in cancer Treatment?

This revelation is particularly encouraging because pharmaceuticals already exist that target CGRP and RAMP1 – namely, drugs used to treat migraines. Researchers beleive these therapies could be swiftly adapted for cancer treatment, significantly shortening the time it takes to bring new options to patients.

Dr.Pavitha Parathan, lead author of the study published in BMJ Oncology, explained the unexpected findings. “we were surprised to observe not only nerve fibers containing CGRP within the tumors actively promoting their expansion, but also the tumor cells themselves producing CGRP,” she stated. “This highlights a previously unknown mechanism by which tumors manipulate their surrounding surroundings to sustain growth.”

She continued, “The encouraging news is that we may already have drugs available to block this process and halt tumor progression. This represents a druggable pathway with existing,well-tolerated therapies,aligning with our commitment to developing cancer treatments that are both effective and patient-amiable.”

Genetic Engineering Confirms Findings

to validate their results, the research team employed advanced genetic engineering techniques. By eliminating the RAMP1 receptor in tumor cells, they observed a substantial reduction in tumor growth. These results powerfully supported the link between the nervous system and cancer progression.

Dr. Lisa Mielke, senior author of the study and Laboratory Head at the Olivia Newton-John Cancer Research Institute (ONJCRI) and La Trobe School of Cancer medicine, emphasized the significance of this emerging field. “The role of the nervous system in cancer is a remarkably promising area of research with the potential to unlock entirely new treatment strategies.”

Dr. Mielke added, “Our next step involves rigorously testing existing migraine therapies designed to inhibit CGRP, with the aim of repurposing these drugs for cancer treatment. Ultimately, we envision incorporating these CGRP inhibitors into clinical trials alongside established colorectal cancer therapies.”

The Global Impact of Gastrointestinal cancers

Gastrointestinal cancers represent a substantial global health burden. According to the World Health Organization, these cancers account for approximately one in four cancer cases, totaling 4.8 million diagnoses worldwide, and are responsible for one in three cancer-related deaths, with 3.4 million fatalities annually.

Cancer Type Global Cases (Approximate) Global Deaths (Approximate)
Colorectal Cancer 1.1 Million 700,000
Stomach Cancer 1 Million 788,000
Esophageal Cancer 604,000 558,000

Did You Know? The gut microbiome,the community of microorganisms living in your digestive system,also plays a critical role in influencing the nervous system and can impact cancer development.

Pro Tip: Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can support a robust gut microbiome and potentially reduce cancer risk.

What are your thoughts on repurposing existing drugs for new applications in cancer treatment? Do you believe further research into the gut-brain connection holds the key to unlocking more effective therapies?

Understanding the Nervous system’s Role in cancer

For decades, cancer research has primarily focused on the tumor itself. However, emerging evidence increasingly demonstrates that the surrounding microenvironment – including the nervous system – profoundly influences tumor growth, metastasis, and response to therapy. The interplay between nerves, immune cells, and cancer cells is a complex and dynamic process. Research published in Nature Reviews Cancer highlights the growing understanding of these interactions and their potential for therapeutic intervention.

Frequently Asked Questions About Cancer and the Nervous System

  • What is CGRP and how does it affect cancer? CGRP (Calcitonin Gene-Related Peptide) is a neuropeptide that, in this study, was shown to promote tumor growth in gastrointestinal cancers.
  • Can migraine drugs really be used to treat cancer? Research suggests that drugs targeting CGRP and RAMP1, already used for migraines, could potentially be repurposed for cancer treatment, requiring further clinical trials.
  • What is the ‘second brain’ in the gut? The ‘second brain’ refers to the enteric nervous system,a complex network of neurons within the digestive system that communicates with the central nervous system.
  • How does the nervous system influence tumor growth? The nervous system can release signaling molecules that either promote or inhibit tumor growth, depending on the context.
  • What are the next steps in this research? The researchers plan to test existing migraine therapies in clinical trials to determine their effectiveness in treating gastrointestinal cancers.
  • What types of gastrointestinal cancers were studied? Specifically, colorectal and stomach cancers were the focus of this research.
  • Is there a link between gut health and cancer risk? Yes, the gut microbiome and the enteric nervous system are increasingly recognized as playing a role in cancer development and progression.

How might understanding the gut-brain axis lead to new therapeutic strategies for gastrointestinal cancers beyond customary chemotherapy or surgery?

Unmasking the Nervous System’s Role in Driving Gastrointestinal Cancer Growth

The Gut-Brain Axis and Cancer: A Complex Interplay

For years, research focused primarily on the genetic and cellular mechanisms driving gastrointestinal cancer (GI cancer). Though, a growing body of evidence highlights a crucial, frequently enough overlooked player: the nervous system. Specifically, the intricate communication network known as the gut-brain axis is now recognized as a significant modulator of cancer progression, influencing everything from tumor initiation to metastasis. This isn’t simply about “stress” causing cancer; it’s a complex biological interaction involving neurotransmitters, immune cells, and the tumor microenvironment. Understanding this connection is vital for developing novel cancer therapies.

How the Nervous System Influences GI Cancer Progress

The nervous system impacts GI cancers – including stomach cancer, colorectal cancer, pancreatic cancer, and esophageal cancer – through several key pathways:

* Neurotransmitter release: Nerves within the gut release neurotransmitters like serotonin, dopamine, and norepinephrine. These aren’t just for digestion; they directly influence cancer cell behavior. For example, serotonin can promote tumor growth and angiogenesis (formation of new blood vessels that feed the tumor) in colorectal cancer.

* Immune Modulation: The nervous system profoundly impacts the immune system. Sympathetic nerve activation, often triggered by stress, can suppress anti-tumor immunity, allowing cancer cells to evade detection and destruction. This immunosuppression is a critical factor in cancer metastasis.

* Tumor Microenvironment Alteration: Nerves infiltrate the tumor microenvironment,releasing factors that alter the surrounding cells. This can create a more hospitable environment for cancer growth, promoting proliferation and inhibiting apoptosis (programmed cell death).

* Vagal Nerve Signaling: The vagus nerve, a major component of the parasympathetic nervous system, plays a dual role. While it can sometimes exert anti-tumor effects, it can also contribute to cancer progression depending on the specific cancer type and stage. Research suggests vagal nerve stimulation may have therapeutic potential in certain contexts, but this is still under investigation.

Specific GI Cancers and Nervous System Involvement

The interplay between the nervous system and cancer varies depending on the specific location within the gastrointestinal tract:

* Colorectal Cancer: Increased sympathetic nerve density around colorectal tumors is associated with poorer prognosis. Neurotransmitters released by these nerves promote angiogenesis and immune suppression. Studies have shown a correlation between chronic stress and increased risk of colorectal adenocarcinoma.

* Gastric Cancer (Stomach Cancer): Nerve growth factor (NGF), a neurotrophin, is often overexpressed in stomach cancer, promoting tumor growth and metastasis. The vagus nerve’s role is particularly complex here,with evidence suggesting both pro- and anti-tumor effects.

* Pancreatic cancer: Pancreatic cancer is notoriously aggressive, and the dense desmoplastic stroma (connective tissue) surrounding the tumor is heavily innervated. These nerves contribute to pain, but also promote cancer cell survival and drug resistance. Pancreatic ductal adenocarcinoma often exhibits significant nerve involvement.

* Esophageal Cancer: Similar to stomach cancer, NGF overexpression is common in esophageal adenocarcinoma and squamous cell carcinoma, driving tumor progression. The esophageal plexus, a network of nerves in the esophagus, plays a key role in this process.

The Role of Chronic Stress and Mental Health

While not a direct cause, chronic stress significantly impacts the nervous system and, consequently, can influence cancer risk and progression.

* Cortisol and Immune Suppression: Chronic stress leads to elevated cortisol levels, which suppress immune function, making it harder for the body to fight off cancer cells.

* Sympathetic Nervous System Activation: Prolonged stress keeps the sympathetic nervous system in a constant state of activation, promoting inflammation and creating a tumor-kind environment.

* Behavioral Factors: Stress often leads to unhealthy behaviors like poor diet, lack of exercise, and smoking, all of which are established risk factors for GI cancers.

Emerging Therapies Targeting the Nervous System in cancer

Recognizing the nervous system’s role opens up new avenues for cancer treatment:

* Nerve Growth Factor (NGF) Inhibitors: Drugs targeting NGF are being investigated for their potential to inhibit tumor growth and reduce pain in certain GI cancers.

* sympathetic Nerve Blockade: Blocking sympathetic nerve activity may restore anti-tumor immunity and improve treatment response. This is being explored in clinical trials.

* Vagal Nerve Stimulation (VNS): While still experimental, VNS shows promise in modulating the immune system and perhaps slowing cancer progression in specific cases.

* Psychological Interventions: Stress management techniques like mindfulness,meditation,and cognitive behavioral therapy (CBT) can definately help mitigate the negative effects of stress on the immune system and potentially improve cancer outcomes. Stress reduction is a valuable adjunct to conventional therapies.

Benefits of Understanding the Gut-Brain-Cancer Connection

* Personalized Medicine: Tailoring treatment strategies based on an individual’s nervous system activity and stress levels.

* Novel Drug Targets: Identifying new targets for drug development that disrupt the nervous system’s pro-cancer effects.

* Improved Patient Outcomes: Potentially enhancing the effectiveness of existing cancer therapies and improving survival rates.

* Holistic Cancer Care: Integrating psychological support and stress management into complete cancer care plans.

Millions of people could have lost their sense of smell after COVID-19 without even knowing it

by Dr. Priya Deshmukh - Senior Editor, Health

Millions May Be Living with Undetected Smell Loss After COVID-19, Study Finds

New York, NY – In a startling revelation that could impact millions, a new study published today indicates a significant number of individuals who contracted COVID-19 continue to experience a diminished sense of smell – often without even realizing it. This “silent epidemic” of olfactory impairment, as researchers are calling it, raises concerns about safety, quality of life, and potential long-term neurological effects. This is urgent breaking news for anyone who has had COVID-19.

The Hidden Impact of COVID-19 on Your Sense of Smell

Researchers from New York University Grossman School of Medicine and other American institutions analyzed data from 2,956 people who had been infected with COVID-19 and compared them to a control group of 569 uninfected individuals. The findings, based on an average follow-up of 671 days post-infection, are deeply concerning. While 1,393 COVID-19 survivors reported a decreased sense of smell, objective testing revealed that a staggering 80% actually had hyposmia (reduced sense of smell) or anosmia (complete loss of smell).

But the most surprising discovery? A full 66% of the remaining 1,563 individuals believed their sense of smell was normal, yet testing showed they were also experiencing olfactory impairment. “People who have had COVID-19 are at high risk for olfactory impairment, an issue that is under-appreciated in the community,” explains Dr. Leora Horwitz, study co-author. This underscores a critical point: your brain may be compensating for the loss, masking the problem from your conscious awareness.

Why You Might Not Know You’ve Lost Your Sense of Smell

COVID-19 is now recognized as the leading cause of olfactory dysfunction during the pandemic. The SARS-CoV-2 virus directly attacks cells and receptors within the nasal cavity, damaging the delicate nerve pathways responsible for transmitting scent signals to the brain. However, the impact doesn’t stop there. Researchers believe the virus can also affect the brain regions responsible for sensory perception, leading to a distorted or incomplete experience of smell.

“The brain is remarkably adaptable,” explains Dr. Horwitz. “Over time, it can essentially ‘learn’ to ignore the missing sensory input, leading individuals to believe their sense of smell is intact when it isn’t.” This adaptation, while seemingly helpful, can have serious consequences.

More Than Just Enjoyment: The Dangers of Undetected Smell Loss

A functioning sense of smell is far more than just a source of pleasure when enjoying food or fragrances. It’s a vital safety mechanism, alerting us to dangers like gas leaks, fires, and spoiled food. A compromised sense of smell can silently jeopardize your well-being. Beyond immediate safety concerns, emerging research highlights a potential link between chronic smell loss and an increased risk of neurological diseases, including Alzheimer’s disease. This connection suggests that COVID-19’s impact may extend far beyond the respiratory system, potentially affecting long-term cognitive function.

What Should You Do? Routine Testing is Key

The study’s authors strongly recommend that olfactory testing become a standard component of post-COVID-19 healthcare, particularly for individuals who experienced any loss of taste or smell during their initial infection. Even if you don’t consciously notice a difference, a simple smell test can reveal hidden impairment. “Even if a patient doesn’t realize it right away, the loss of the sense of smell can have a profound impact on mental and physical health,” Dr. Horwitz emphasizes.

Currently, simple scratch-and-sniff tests are used to assess olfactory function. These tests can be administered quickly and easily in a clinical setting. If you suspect you may have experienced a loss of smell, talk to your doctor about getting tested. Early detection and intervention are crucial for maximizing the potential for recovery.

This research is expected to spur further investigation into the mechanisms of olfactory recovery following viral infections, paving the way for more effective treatments in the future. Understanding how the brain adapts to smell loss, and how to reverse that adaptation, is a critical step towards restoring this vital sense for millions of people worldwide. Stay informed and prioritize your health – a seemingly minor symptom like a diminished sense of smell could be a sign of a larger, underlying issue.
