“Isn’t it dementia if the memory is intact?”
no. There is also dementia in which memory appears to be intact. Dementia has different symptoms depending on where the brain is weakened or damaged. Memory is often impaired, but there are cases of dementia in which personality and behavior change first.
Dementia increases with age. On the other hand, ‘frontotemporal dementia’ often begins between the ages of 45 and 65, a young age. Of course, it can also occur in younger 20’s or older 80’s or older. It is a type of degenerative dementia that develops slowly and progresses rapidly, and is a bad type of dementia that ravages lives within a few years. Personality and behavior change, language skills decline, and movement becomes difficult.
There are three types of frontotemporal dementia. There are ‘behavioral variant frontotemporal dementia’, ‘primary progressive aphasia’, and ‘frontotemporal dementia causing impaired motor function’.
3 types of frontotemporal dementia
In ‘behavioral variant frontotemporal dementia’, the frontal lobe, which is the front of the front of the head, weakens, causing personality changes and crazy behavior. Your personality changes as you become impatient and impulsive, your motivation and willpower disappear, and your emotions become dull. Concentration decreases, distraction, and judgment, thinking and foresight are reduced, resulting in an inability to process tasks in an orderly manner.
In ‘Primary Progressive Aphasia’, the anterior part of the temporal lobe weakens, resulting in decreased ability to speak. Comprehension is also reduced. You may say the wrong words, or the word order may be jumbled. Speech becomes slow, phonation becomes difficult, and it becomes difficult to speak. Primary progressive aphasia includes ‘semantic dementia’ and ‘progressive non-fluent aphasia’.
In addition, there is a spectrum of ‘frontotemporal dementia that causes impairment of motor function’. Amyotrophic lateral sclerosis, also known as ‘Lou Gehrig’s disease’, a disease in which muscles weaken and atrophy, ‘cortical basal ganglia degeneration’ in which the limbs become stiff and both arms do not work together There is ‘progressive supranuclear palsy’, in which movement of the pupil becomes unstable or numb.
Frontotemporal dementia is more common at a young age than Alzheimer’s dementia, has less memory impairment, and is less likely to get lost. In Alzheimer’s dementia, the ability to remember or recall words is impaired, whereas in frontotemporal dementia, the ability to understand and speak is greatly weakened.
In one-third of cases, it is genetic, and the specific cause of the disease is uncertain. The rate of weakness varies from person to person, and if it progresses, you will have to lie down due to muscle atrophy, etc. There is no specific medical treatment, and selective serotonin uptake inhibitors, which are antidepressants, are sometimes used to curb impulsive behavior, but cognitive enhancers do not help much.
A person who was docile gets angry easily, or a person with a bad temper becomes calm. Become extremely selfish without thinking about others, do not notice others, engage in antisocial behavior, become lazy in diligent people, develop senile depression, work very poorly, or have trouble understanding others Dementia should be suspected if a lot has changed, such as slow movement or sluggish movement. Even if you don’t have any major memory problems, if people change a lot, it could be dementia.
