What is frontotemporal dementia?

This is a rare but progressive form of dementia. In frontotemporal dementia, nerve cells die. The nerve cells in the forehead and temples are primarily affected. This is the area of ​​the brain in which, according to the German Alzheimer Society, emotions and social behavior are controlled, among other things.

How is this dementia manifested?

Changes in personality, but also in interpersonal behavior accompany almost all patients in the early stages of the disease. At first, this often manifests itself in a kind of laziness. Those affected are becoming more and more superficial, careless, but also thoughtless. They are more irritable, sometimes aggressive and increasingly tactless in social interactions. In addition, they lose their motivation, they no longer feel like their hobbies and they also lose interest in everything else.

Some no longer care about their hygiene, others have constant cravings. As the disease progresses, language disorders are typical – word-finding, naming and language comprehension disorders. The sick speak less and less, in the worst case they fall silent completely. Later there is limited memory performance, and movement disorders are also possible. Complete need for care in the final stage is possible.

At what age do you usually get sick?

How is the disease treated?

A cure is not yet possible. It has not yet been sufficiently clarified why the nerve cells die off. Drugs have been and are being tested in studies, but so far there is no targeted treatment option. Instead, the psychological effects of the disease, i.e. the behavioral problems, are usually treated. Among other things, antidepressants are used, which regulate moods and alleviate listlessness. Exercise and creativity can also help. However, the patients usually do not realize that they are ill and therefore do not want to be treated.

How does the disease affect family members?

Relatives find themselves exposed to unpleasant traits such as aggression, unpredictability and a lack of empathy. It is also stressful for those close to you that the relationship with the sick person changes because they increasingly lose interest in their counterpart.
