F03: Unspecified dementia

You have a dementia disease.

The brain is vital for thinking, remembering and moving. For this purpose, there are many nerve cells in the brain. If these nerve cells are damaged, the brain is no longer able to carry out those functions so well. Your brain is no longer able to carry out different tasks so well due to the condition. This is called dementia. As a result, your memory will gradually get worse. You are finding it difficult to memorize new things. One may often then no longer be able to judge everyday situations so well. The disease often makes it difficult to deal with everyday life. It is often difficult to remember the right word for something. Your mood may swing and suddenly change. One may feel depressed and lose the desire to do anything. One may also become more mistrustful or feel persecuted. Sometimes one can no longer move or speak so well.

There are many reasons for dementia. For example, if the brain is no longer getting enough blood, it can be damaged. Proteins that damage the brain may also be deposited.
