Alzhimer is the Kind of Disease That Causes Mental Damage
The disease is characterized by a progressive decline in mental functions. The disease is caused by certain proteins (Amyloid precursor protein : APP) degrade abnormal. This causes abnormal degradation (beta amyloid) which aggregates form. Probably this form of amyloid damaging nerves which then die. In a post mortem examination is greatly reduced cortex (atrophy) found in cells located outside the amyloid deposits (senile plaques), the cell located in amyloid deposits (neuro fibrillary tangles) and deposits around blood vessels. These deposits are not evenly distributed over the cortex. In particular parts of the cortex in which memory functions are localized, are done in the beginning. The disease begins with memory disorders. In the beginning is particularly disturbed imprinting, this new information is not saved. Patient asks, for example several times a day and forget the same arrangements. Information is stored in the past as memories of the past is still available. As the disease progresses, problems arise even in the long term memory. Furthermore arise early in the disease find language disorders such as word problems, disturbances in language comprehension and word production decreased.
