Motor (psychomotor) disorders - a stupor and excitement

motor psychomotor disturbances Psychomotor - a complex motor acts the person closely associated with mental activity and is representative of the constitution.The term "psychomotor" is used to distinguish between complex movements associated with mental activity of the elementary motor reactions associated with the more simple reflex activity of the central nervous system.

What is psychomotor disturbances

Psychomotor disorder - is a violation of a complex motor behavior, which may occur at various nervous and mental diseases Mental illness - ashamed to ask for help? Mental illness - ashamed to ask for help? .For rough focal lesions of the brain (for example, cerebral atherosclerosis) motor function disorders occur in the form of paralysis or paresis, with generalized organic processes (for example, brain atrophy - reducing it in volume) such disorders may be limited to the general slowness, poverty voluntary movements, lethargyfacial expressions and gestures, monotone speech, and changes in the overall stiffness of gait (small steps).

arise psychomotor disorders and some psychiatric disorders.For example, in manic-depressive psychosis Manic-depressive psychosis - what phases the most dangerous? Manic-depressive illness - which are the most dangerous phase? during the depressive phase comes the general depression of the psyche, in manic states - general motor stimulation.

At some psychogenic disorders psychomotor change is sharply painful character, for example, in hysterical reactions relatively frequently observed partial or complete loss of movement in the extremities (hysterical paralysis), decreased strength of movement, coordination of various disorders.While there are a variety of hysterical fit mimic expressive movement and protective nature.

particular importance psychomotor disorders arising from katotonicheskom syndrome.These include movement disorders from minor changes in the form of motor slackness of facial expressions, mannerisms, pretentiousness postures, movements and gait to severe manifestations of catatonic stupor (catatonia - a neuro-psychiatric disorder, which is expressed in muscle spasms and infringement of voluntary movements) and the phenomena of catalepsy (numbnessor setting the loss of the capacity for voluntary movement occurs, such as hysteria).

Psychomotor disorders fall into disorder, accompanied by a decrease in volume movements (hypokinesia), an increase of movements (hyperkinesia) and involuntary movements that are part of generally smooth and controlled movements of the face and limbs (dyskinesia)


Byhypokinesia include various forms of stupor - a mental disorder Mental Disorders - when life is not a pleasant Mental Disorders - when life is fun of oppression all mental activity, including movements of thought and speech.Meets the following types of stupor:

  • depressive stupor or melancholic stupor - nostalgia, immobility, but retain the ability to respond in some way to the treatment;
  • hallucinatory stupor - occurs when hallucinations while mimic immobility combined with reactions to the content of hallucinations - mimicry expresses fear, surprise, joy;this condition may occur in some cases of poisoning, organic psychosis, schizophrenia Schizophrenia - to blame civilization Schizophrenia - to blame civilization ;
  • asthenic stupor - lethargy and indifference to everything, patients understand what they are asked, but did not have the strength and desire to answer;
  • hysterical stupor usually occurs in individuals with hysterical traits (emotionally, wanting to be the center of attention, demonstrative) - the patient can lie still for days and did not respond to treatment;if you make it up, it will resist;
  • psychogenic stupor - the body's reaction to trauma;while stillness combines with a variety of disorders of the autonomic nervous system (which supplies the organs and blood vessels) - rapid heartbeat, sweating, increased or decreased blood pressure;
  • cataleptic stupor and waxy flexibility - is a condition in which against the backdrop of increased muscle tone occurs in patients with the ability to keep for a long time to give them a position.

In addition to hypokinesia include such a condition as mutism - silence, when the patient does not respond to questions and does not come to anyone in contact.


giperkinez arise amid increasing mental and motor activity, and are enforced automatic movement, arising from the uncontrolled muscle contractions.For hyperkinesis include:

  • manic excitement - called pathologically elevated mood;with milder forms of the disease are coordinated movements, correct behavior keeps focus, accompanied by a loud rapid speech;in severe forms of movement losing logic and can not be combined with the fact that the patient says;
  • hysterical excitement - usually appears as a response to their environment, characterized by a visible and intensified if the patient pay attention;
  • disorganized excitation - a cheerful absurd and meaningless behavior elaborate mimicry;found in schizophrenia;
  • hallucinatory excitement - the patient alive react to the content of their hallucinations.

in neurology and psychiatry of psychomotor research plays an important role.Motor appearance of the patient, his manner, posture, gestures, and their compliance with the nature of the statements is an important feature, allowing the correct diagnosis.
