Family Faces Alzheimer’s Reality: A Daughter’s Heartbreaking Journey Supporting Her Mother
The relentless progression of Alzheimer’s disease continues to cast a long shadow over families worldwide. In The Netherlands, one family’s story is being shared to shed light on the profound impact of this debilitating condition.
Nanka is currently navigating the complexities of caring for her mother, Rika, who is battling Alzheimer’s. Their journey, filled with love, sacrifice, and heartbreaking realities, underscores the urgent need for increased awareness and support for those affected by dementia.
A Family History With Alzheimer’s
Alzheimer’s disease is no stranger to Nanka’s family. Rika’s father, Nanka’s grandfather, succumbed to the disease years prior.This family history prompted early testing for Rika, although initial diagnoses proved challenging for neurologists due to the disease’s nascent stage.
Seeking clarity, Rika pursued a third opinion at an Amsterdam hospital. Genetic testing, prompted by her father’s history, confirmed Rika carried a hereditary gene linked to Alzheimer’s disease.
Embracing Life after Diagnosis
Following Rika’s diagnosis, Nanka’s family resolved to make the most of their time together. “We immediately said to each other: ‘Mama is sick, so we are going to do as many fun things as possible. We’re going to get everything in it,'” nanka explained.
Having witnessed her own father’s battle with Alzheimer’s disease, Rika expressed her fears, stating, “I never want to end up in a nursing home.” She was mindful of the burden on her family, hoping to spare them suffering while acknowledging her awareness would eventually fade.
The Rapid Progression Of Alzheimer’s
For four years after her diagnosis, Rika remained at home. “I think it all went pretty fast for four years. She has deteriorated rapidly,” Nanka recounted. The responsibilities of caregiving quickly escalated, with Nanka unexpectedly assisting her mother with daily tasks like dressing and eating.
Six years post-diagnosis, Rika is now in the advanced stages of Alzheimer’s disease. Nanka believes her mother still recognizes her,but meaningful dialog is limited. Nanka, along with her father and sister, visits Rika three times a week.
“It is very difficult to see your mother like that. It is no longer from outside my mother on the inside,” Nanka shares, encapsulating the emotional toll of witnessing a loved one’s decline.
Did You Know? According to the alzheimer’s Association, in 2024, an estimated 6.9 million Americans age 65 and older are living with Alzheimer’s disease. This number is projected to rise to nearly 13 million by 2050 unless medical breakthroughs occur. Learn More
Life On Hold: Sacrifices And dreams Deferred
Nanka describes her life as being “on a break” while caring for her mother. She continues to live at home, finding it difficult to leave her father alone. Nanka also paused her HBO studies, finding it overwhelming to balance her education with caregiving responsibilities.
The situation has also impacted Nanka’s personal life. She finds it challenging to meet new people, not wanting to immediately burden them with her family’s situation. Her aspirations of becoming a stewardess are also on hold, as the demanding travel schedule would keep her away from home.
“My dreams and ambitions will come later,” Nanka says, demonstrating her unwavering commitment to her family.
Living In A Waiting Room
Nanka and her family face the uncertainty of not knowing how much time Rika has left. “It is very difficult to estimate,she is now quite stable,but it can also happen that she suddenly dies,for example due to an additional complication,” Nanka explains.
She poignantly describes their situation as being “in a kind of waiting room of death,” postponing their grief while preparing for the inevitable. Nanka reflects on the milestones her mother will miss, such as future relationships, marriage, or the birth of a child.”I am anxiously looking at the future, especially since I cannot imagine what it is like to have no mother at all.”
Pro Tip: Consider joining a local or online support group for caregivers of individuals with Alzheimer’s disease. Sharing experiences and advice with others in similar situations can provide invaluable emotional support and practical guidance.
Alzheimer’s Disease: Understanding the Impact
Alzheimer’s disease is a progressive and irreversible brain disorder that gradually destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks. While age is the greatest known risk factor, Alzheimer’s disease is not a normal part of aging.
According to the World Health Organization (WHO), dementia affects around 55 million people worldwide, with Alzheimer’s disease being the most common form, contributing to 60-70% of cases. The global cost of dementia is estimated to be over $1.3 trillion USD annually.

Ancient Leprosy Genomes Uncovered In South America, Redefining Disease Origins
In a stunning scientific revelation, a team of researchers has unearthed
ancient leprosy
genomes dating back 4,000 years in South America. This groundbreaking discovery challenges long-held beliefs about the origins and spread of the disease, suggesting it was present in the Americas millennia before the arrival of Europeans.
The findings, published in a recent scientific journal, are reshaping our understanding of
Mycobacterium lepromatosis
, one of the two bacteria known to cause leprosy, and its evolutionary journey.
Study:
Nature Ecology & Evolution
Ancient Genomes Rewrite Leprosy’s History
The research team meticulously analyzed
M. lepromatosis
genomes extracted from 4,000-year-old human skeletal remains discovered in distinct archaeological sites. These findings provide critical insights into the disease’s presence in the region long before documented European contact.
From nineteen bones and thirty-five teeth, exhibiting pathological lesions suggestive of infection and belonging to forty-one individuals sampled from five different archaeological sites in Chile, the team was able to extract a small quantity of tissue and constructed a DNA library for sequencing.
Unearthing The Ancient Evidence
Researchers employed a hypothesis-free method to screen data for various pathogenic viruses and bacteria. This revealed thousands of DNA fragments with homology to
M. lepromatosis
in two archeological tissues.
Specifically, a tooth from a male subject (ECR003) at the El Cerrito site and a tibia from another male (ECR001) at the La Herradura site which were radiocarbon dated and found to be contemporaneous from 3,900 to 4,100 years ago.
Did You Know? Radiocarbon dating, a method for determining the age of an object containing organic material by using the properties of radiocarbon (carbon-14), is accurate up to 50,000 years.
genomic analysis confirms Ancient Strains
The team enriched Dna libraries using a probe set designed from a modern
M. Leprosy
reference panel, which resulted in some uneven coverage but yielded exceptionally high-quality ancient genomes. Competitive mapping was then used to distinguish the various mycobacterial species.
The mean genomic coverage was significant, with 74-fold coverage for ECR003 and 45-fold coverage for ECR001 when mapped against a modern
M.lepromatosis
genome reference isolated from a Mexican patient.
Divergence Between Leprosy Pathogens
The study further investigated the divergence between
M. Leprosy
and
M. lepromatosis
, considering the genomic decay and reduction observed in
M. Leprosy
over evolutionary timescales. Pangenomic analysis indicated a high level of divergence, with only about half of the protein-coding regions showing at least 50% sequence homology between the two pathogens.
A mapping-based approach further revealed that the two pathogens shared only approximately 25% nucleotide identity.
Phylogenetic Analysis And Evolutionary Timelines
Analyzing the 16S ribosomal RNA locus indicated that
M. Leprosy
is the closest relative to
M. lepromatosis
, despite their extensive divergence.
A conservative genome-level phylogenetic reconstruction,focusing on diversity within
M. lepromatosis
, was performed, limited to the two ancient genomes, four modern human genomes, and six modern red squirrel genomes.
The analysis revealed a clear separation between rodent- and human-associated lineages, with the ancient genomes forming a sister clade to the cluster of all human
M. lepromatosis
sequences.
Pro Tip: Clade refers to a group of organisms that consists of a common ancestor and all its lineal descendants, representing a branch on the tree of life.
The study’s comparative analysis also questioned a previously reported
M. lepromatosis
genome from India, suggesting it showed greater homology to
M. Leprosy
through competitive mapping.
Revised Evolutionary Rates
Time-calibrated phylogenetic trees were generated using the radiocarbon ages of ECR001 and ECR003 skeletal elements, along with the collection year of all modern genomes. This allowed researchers to estimate evolutionary rates and divergence times.
The evolutionary rate was estimated at 6.91 x 10
-9
substitutions per site per year for
M. lepromatosis
, aligning with estimates for
M. Leprosy
. the median time for the most recent common ancestor (tMRCA) of
M. lepromatosis
was estimated to be approximately 26,800 years ago, with a wide potential date range of 4,206 to 115,340 years ago due to the limited number of available genomes.
The divergence time for genomes from human hosts was estimated to be around 12,600 years (with a range of 5,304 to 49,659 years ago), while the tMRCA for the red squirrel clade was a much more recent 440 years.
Key Implications Of The Findings
The study’s findings indicate a distinct and extended evolutionary history for
M. lepromatosis
, potentially dating back to the Pleistocene-Holocene transition.This is in contrast to other major pathogens like
M. Leprosy
and
Yersinia pestis
which are believed to have emerged more recently during the Neolithic era with the rise of agriculture.
The presence of
M. lepromatosis
in south America before known contact with European or Oceanian populations suggests transmission within human groups during early peopling events or its endemicity in a different reservoir species. This challenges the assumption that the disease was introduced post-colonially, suggesting it may be one of the few diseases originating in the Americas.
One Health Perspective
Framing these discoveries within a ‘one Health’ perspective, the study emphasizes the need for broader surveillance of animal reservoirs to understand the disease’s ecology and zoonotic potential.
This holistic approach integrates human, animal, and environmental health to address complex health challenges effectively.
How might understanding ancient disease genomes impact modern public health strategies?
