CHRONIC TACTILE HALLUCINOSIS

   The expression chronische taktile Halluzinose was proposed in 1954 by the German neurologist and psychiatrist Klaus Conrad (1905-1961) and his colleague N. Bers to denote a syndrome characterized by * formicative hallucinations, parasitic or other dermatozoic delusions, and a chronic course. Conrad and Bers were under the impression that chronic tactile hallucinosis was most prevalent among women of 50 years of age and older. As a nosological category, chronic tactile hallucinosis is classified as a specific type of * hallucinosic syndrome.
