Degenerative disorder: Alzheimer's disease and other forms of dementia

These frustration are characterised by deterioration or progressing loss of one or several functions-memories because of a degeneration of the central nervous system. They can be reflected negatively in all activity of a brain or on separately taken function. Usually similar frustration arise at people of old age. It is necessary to distinguish, when deterioration of activity of memory is a consequence of degenerate process, and when - result of a pathology, or in what conditions they can be considered as displays of moderate forgetfulness. Probably, it would be useful to spend among people of old age neuropsychological researches which would help to give answers to these questions.

The Alzheimer's disease

Causes brain utter defeat, an extensive atrophy of a bark of a brain and expansion of the ventricles. It is accompanied by loss of neurons, reduction of crinkles and morphological changes of a brain. Usually these changes occur not suddenly, they progress gradually. Despite existence of individual distinctions of a current of disease, it is possible to allocate and describe four consecutive phases of its development though not all people amazed with an Alzheimer's disease, pass through them.

4 phases

Duration of each phase has no strictly certain borders. Depending on a condition of the patient there is a big variety of their time forms.

  • 1st phase. It is characterised by occurrence of emotional symptoms, loss of memory and interest to something, irritability increase. Frequently the person refuses to pay attention to existence of problems or any deviations. As infringement of functioning of memory is one of the earliest symptoms if displays of considerable frustration of memory are observed at the person of old age, probably, intervention of the expert as the sick person can not give itself the report that with it not everything is all right is required. When memory loss is a symptom of a heavy degenerate pathology, it is usually shown in inability to remember the new information or inability to acquisition of new skills.
  • 2nd phase. It is distinguished on an aggravation of emotional and social problems. Patients become less capable to service of and the decision of the problems because of strong memory blackouts, absence of the personal initiative, inability to answer questions of associates.
  • 3rd phase. Because of difficulties of perception and problems with speech of infringement of motor skills become obvious and so, that the person at all in a condition to put on itself. Changes of the person amplify, the person sinks into dotage and is in uninhibited a condition. He does not realise, that is sick.
  • 4th phase. there Is a progressing loss of all functions. The patient becomes unsociable, says only short phrases, practically does not communicate with associates, becomes apathetic, speaks hardly. Starts to forget the most people close to it, even members of the family, and in one fine day cannot recollect the name.

Other kinds of senile weak-mindedness

Trouble in Mind is a progressing loss of powers of thinking at which memory, ability to reflect, concentrate attention and ability to get new skills are reduced, and there can come full destruction of the person.

There are other kinds of diseases of the degenerate character, meeting less often, however they have the same fatal influence on activity of memory.

The Most widespread are: illness of Parkinson, trochee Huntington's and progressing supranu-klearnyj a paralysis. All 3 diseases have negative influence mainly at subcrustal level. For all 3 diseases difficulties with spontaneous recollection of information are characteristic, thus the information cognizance reaches normal level, patients use keys for information restoration. The first phases of diseases are characterised by delay of psychomotor and informative activity, insignificant memory blackouts. At late stages there is an inability to storing of new skills, prevalence of airs over other motor systems.

- Illness Parkinson's. Defeat the basal ganglia in a brain, a striped body and black substance. The basic feature is trembling which can give way to any movements or obviously expressed immovability.

  • Trochee Huntington. Progressing chronic a trochee, inherited on autosomno-domi-nantnomu to type. The basic feature are convulsive involuntary movements.
  • Progressing supranuklearny a paralysis.

The Paralysis which is a consequence of defeat central impellent neurons.
