A doctor has named a non-obvious factor that triggers the development of dementia

“To say that the transferred viral disease will necessarily lead to dementia, of course, it is impossible. For example, 99 per cent of people have the herpes virus. Only in a very small number of patients it causes encephalitis (acute inflammation of the brain), the malignant form of which sometimes leads to cognitive disorders,” she concluded.

Earlier, neurologist Richard Restak named a non-obvious early symptom of dementia. Restak pointed out that the inability to perform well-practised actions is called apraxia.
