Mental retardation - if the mind is underdeveloped
(retardation), moderate mental retardation (imbecility), and severe mental retardation (idiocy). Congenital dementia is a permanent condition, which is not peculiar to the further deepening lack of mental activity.
Congenital dementia is expressed in the inability to abstract thinking and understanding of specific situations, a limited supply of knowledge and difficulty of acquisition, underdevelopment of speech, memory weakness and poverty of emotions

Epilepsy - a sacred disease
or schizophrenia). Dementia may be progressive when her symptoms are increasing, and not progressing. Changes can capture the whole brain (total dementia), or some part of it (partial dementia occurs for example after head trauma).
It was found that almost 30% of patients with dementia characterized by family history, and the nature of their prevailing anxious-hypochondriac traits with a penchant for long-term memorization of negative emotions. Dementia resulting from such people, characterized by slow onset, progressive course with the development of dementia with a total dysfunction of writing, reading, and even language. In the future, it is joined by a violation of control functions such as defecation and urination.
Pick's disease changes are expressed primarily in the frontal and temporal lobes of the brain. Thus there is atrophy (shrinking) of certain parts of the brain. The average age of the patients at the beginning of the disease - 55 years, the average duration of their life - 6 years.
In the case of frontal lobe lesion patient becomes sluggish, inactive, apathetic, indifferent to yourself and your appearance. However, when they are outside motives may exhibit some activity.

First and foremost the ability to disappear subtle and complex movements, the development in recent years. Impoverish the vocabulary, the patient begins to miss a word. Eventually developing dementia rough, full of decay and speech recognition. Patients lie in the fetal position (in the womb), lead a vegetative lifestyle.
Similarly, the causes of Alzheimer's disease are not known, but they believe that to blame heredity, resulting in a change in the structure of one of the types of protein, which starts to accumulate in the nerve cells, disrupting their activities.
Treatment of dementia
Since dementia may have different causes, and then they must be treated individually and complex. In the initial stages of the disease used restorative therapy, vitamin-mineral complexes, nootropic drugs (for example, piracetam - contribute to improving the supply of oxygen the brain).
