Sensory disorders are psychopathic phenomena in which difficulties and abnormalities occur in the process of reflecting individual properties of stimuli. Common sensory disorders are: ① Sensory hypersensitivity. Abnormally high perceptual ability to external stimuli. ② Sensory hypoesthesia and sensory deficit. Abnormal decrease in the ability to perceive external stimuli. (3) Sensory inversion. The false sensation of the nature of external stimuli. ④Internal sensory discomfort. The discomfort of stimuli from inside the body is different. Psychological studies on the brain mechanisms of sensory disorders have confirmed that damage to the posterior region of the central sulcus of the human cerebral cortex is associated with the development of sensory disorders. Sensory disorders can have a wide range of effects on various psychological processes in humans and can result in perceptual impairments that disrupt motor feedback information and lead to dysfunctional motor functions. In clinical practice, both neurological and psychiatric disorders can have symptoms of sensory impairment, with the former being more common.
