Dementia
So dementia is, first of all, not a disease, but a syndrome (a set of symptoms) [6] caused by organic damage to the brain (often the damage to the brain is a severe one) [7], which leads to the impairment of many cognitive functions. These include thinking process, speech formation, judgment, memory, counting, understanding, orientation, and learning ability.
The symptoms of dementia are caused by various medical conditions that affect the brain. There are more than 130 diseases in the world that cause impairment of the functions of the cognitive apparatus.

There is a widespread belief that dementia is an irreversible decline in cognitive functions, a loss of short-term memory caused by organic damage to the brain. However, this is not entirely true. Some of the diseases that lead to dementia are curable. If treatment [8] is started on time, many of their cognitive functions can be preserved. Therefore, at the first sign of dementia, you should always see your doctor.
