SENSOPATIYA (sensopathia, singular; lat. sensus feeling, feeling + Greek pathos suffering, a disease) — group of the psychopathological symptoms which are shown disturbance of sensory perception (feelings, perception, representations). It is frequent

C. precede education difficult psikhopatol. syndromes, are their part and the wedge, pictures can create an affective background.

Distinguish quantitative and high-quality disturbances of sensory perception. Carry to quantitative disturbances hyperesthesias and hypesthesias. At hyperesthesias the susceptibility of usual external irritants is raised: usual light, sounds, smells, hiting at to a body become intolerable for the patient. At a hypesthesia the susceptibility of external irritants is considerably lowered. Sounds become deafs, voices are heard vaguely, as if from far away, surrounding is perceived faded, shapeless, stiffened. Treat high-quality disturbances of sensory perception senesthopathias (see), and also so-called synesthesias — emergence at irritation of a certain sense body both adequate feelings, and inadequate, napr, feeling of color during the hearing of music.

Pages include disorders of touch synthesis — change body schemes (see), metamorphopsias (see), disturbances of space perception, time, motion of bodies or variability of the world around. Nek-ry researchers carry to S. also illusions (see), hallucinations (see). At metamorphopsias perceptions of size and a form of objects and people are distorted: they seem much increased (makroisiya) or excessively reduced (micropsia), sometimes deformed — slanted, curved, disfigured. Also perception of parts of a body of people, especially persons is distorted. Space perceptions, i.e. stereoscopy, relief, the plane of objects are broken, to-rye move away, at the same time decreasing, come nearer, increasing. Quite often perception of time changes. So, at depressions of endogenous type patients speak about emptiness of surrounding space and lack of time more often, at schizophrenia (see) complain of a stop of time (the world stopped in time). At epilepsy (see) disturbances of perception of the sequence and duration of time are observed (in a flash there take place long experiences). These states can be also followed by change of perception of the movement and variability of the world around: objects seem or motionless, stiffened, lifeless, or, on the contrary, everything falls, fluctuates, gets into eyes of the patient, everything is in the rough movement (an optical storm).

S.'s transformation in more difficult syndromes is possible derealization (cm), depersonalization (see), in hypochiondrial syndrome (see).

Pages can be observed at neurosises (see), psychoses (see. Mental diseases ). At relative safety of consciousness patients usually say that neither the outside world, nor their body change that all this seems to them in connection with painful change of feelings, perceptions. During the obscuring consciousnesses (see), and also at endogenous psychoses (schizophrenia, maniac-depressive psychosis) the critical relation of patients to the patol. to feelings it is usually broken.

The page should distinguish from other forms of disorders of perceptions, napr, from agnosias (see), at a cut recognition, from the hallucinations (see) which are characterized by imaginary reflection of objective objects from illusions with their wrong perception of real objects is broken.
