Hysterical psychosis is a specific clinical manifestation of dissociative disorder, the main clinical symptoms of which are sudden onset after mental stimulation, mainly manifested by hazy consciousness, wanderlust, childish and disorganized behavior, and recurrent episodes of fantasy life. Patients often have insufficient self-awareness and adopt an indifferent attitude toward the disease. The onset of the disease is usually acute, with a rapid onset and termination, and its course can last several weeks, with brief intervals during which there are no sequelae after remission, but the disease is prone to relapse.
