Tactile hallucination is the false perception of tactile sensory input that creates a hallucinatory sensation of physical contact with an imaginary object. [1] It is caused by the faulty integration of the tactile sensory neural signals generated in the spinal cord and the thalamus and sent to the primary somatosensory cortex (SI) and secondary ...
Stimulant psychosis is a mental disorder characterized by psychotic symptoms such as hallucinations, paranoid ideation, delusions, disorganized thinking, and grossly disorganized behaviour. It typically occurs following an overdose or several day binge on psychostimulants , [ 1 ] although it can occur in the course of stimulant therapy ...

[7] The delusions cannot be due to the effects of a drug , medication , or general medical condition , and delusional disorder cannot be diagnosed in an ...
Tactile defensiveness: negative reaction to tactile stimuli; Visual perceptual deficits: poor form and space perception and visual motor functions; Somatodyspraxia: poor motor planning (related to poor information coming from the tactile and proprioceptive systems) Auditory-language problems
The treatment of psychosis depends on the specific diagnosis (such as schizophrenia, bipolar disorder or substance intoxication). The first-line treatment for many psychotic disorders is antipsychotic medication, [135] which can reduce the positive symptoms of psychosis in about 7 to 14 days. For youth or adolescents, treatment options include ...
Delusions occur without hallucinations in about one-half to two-thirds of patients with psychotic depression. [2] Hallucinations can be auditory, visual, olfactory (smell), or tactile (touch), and are congruent with delusional material. [2] Affect is sad, not flat. Severe anhedonia, loss of interest, and psychomotor retardation are typically ...
Sensory deprivation or perceptual isolation [1] is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down.
Hallucinogen persisting perception disorder (HPPD) is a non-psychotic disorder in which a person experiences apparent lasting or persistent visual hallucinations or perceptual distortions after using drugs, [1] including but not limited to psychedelics, dissociatives, entactogens, tetrahydrocannabinol (THC), and SSRIs.
