Biochemistry psychoses

Assumptions about the allocation of "special air" in the nerve endings made by W. Cullen (1776), which therefore believed that all diseases are nervous, and proposed to refer to them, the term "neurosis". Advances Neurosciences allowed now to establish that the transfer of information from one neuron to another is carried out as a result of specific binding neyrostruktur ("synapses") by allocating specific chemicals (neurotransmitters neurotransmitters). Identified and described various mediators that are released at the moment of excitation in the synapses, resulting in a chemical reaction with proteins retse

Genetics of mental illness

On the role of degeneration first spoke quite clearly B. Morel (1857). He led the clinical evidence of accumulation in different families degenerate stigmata of degeneration, so that in the third and fourth generations are born already mentally ill children, exhibiting, for example, signs of dementia praecox (premature dementia). Since the second half of the XX century the study of the role of heredity in the origin of psychosis is becoming increasingly important. Clinical experience with the development of genetics as a precise science became supported by conclusive information on violations of the structure of certain genes that are part of a set of human chromosomes. However, the direct

Etiology and pathogenesis of mental disorders

The essence of psychosis to date have not been fully elucidated. In XX century, due to the success of genetics, molecular genetics, neuroimmunology, neurochemistry, physiology, ie, the entire complex of Neurosciences, many mechanisms for the development of conditions such as depression, anxiety, fear, excitement, have become clearer; opportunity accurate DNA diagnosing a number of diseases (Huntington's chorea, Down syndrome, mental retardation other differentiated). Such a "breakthrough" in science has become especially noticeable in the last decade of XX century, which has been designated by WHO as "the decade of the brain." By the beginning of the XXI century was decoded the human genome, and scientists got their py
