- One of the varieties of presenile dementia that occurs as a result of atrophy mainly in the temporal and parietal lobes of the brain. The disease begins in the middle of 55 years, it is much more common than Pick's disease. Women suffer 3-5 times more often than men. The disease begins with increasing memory impairment. However, patients notice at these violations and the associated decline in intellectual abilities and are trying to hide it from others. With increasing memory impairment a sense of loss, confusion, bewilderment, which in some cases causes them to seek medical attention. Gradually the patients are no longer navigate the site and time of memory drop accumulated knowledge, experience and skills. The process of precipitation goes from the present to the past, ie, forgotten by the next first-time event, and then more distant. Initially, suffers memory for abstract concepts - names, dates, terms, names. Then join violation memory, and therefore the patients start to confuse the chronological sequence of events, both generally and in his personal life. The patients can not tell where they are, your home address (can be called with the address of the house where they lived in his youth). After leaving the house, did not find the way back. Violated recognition of shapes, colors, people, spatial arrangement.
The people from the inner circle start calling other people names, for example, representatives of the younger generation - the names of his brothers and sisters, then - the names of long-dead relatives and friends. In the end, the patients no longer recognize their own appearance: looking at myself in the mirror, may ask - "What is this old woman?"

A closely related speech disorders, the depletion of the stock of words, the lack of understanding of what he heard, read or written with his own hand. Therefore, a letter is more a set of irregular circles, curves, and then - straight lines. It becomes more and more incomprehensible, consisting of parts of words and syllables.
Patients gradually lose all the skills acquired over his life and habitual actions: can not get dressed, prepare meals, do some elementary work, for example, sew a button, and ultimately - to fulfill even one of purposeful action. The mood is unstable: apathy, punctuated by fun, excitement, continuous and incomprehensible speech. can be observed gait disturbances, seizures, reflex motion of lips in the final stage of the disease, tongue (sucking, smacking, chewing). Unfavorable outcome: a state of complete insanity. Death occurs either during a seizure, or in connection with the Affiliate infection.
