  • Brief Psychotic Disorder
    by Anu Stephen on January 1, 2022

    Brief psychotic disorder (BPD) according to DSM-5 is the sudden onset of psychotic behavior that lasts less than 1 month followed by complete remission with possible future relapses. It is differentiated from schizophreniform disorder and schizophrenia by the duration of the psychosis. The diagnosis is often anticipatory or retrospective due to the diagnostic requirement of complete remission within 1 month. Brief psychotic disorder is an acute but transient disorder with the onset of one or...

  • Catatonic Schizophrenia
    by Ankit Jain on January 1, 2022

    Schizophrenia was divided into five subtypes, including disorganized schizophrenia, paranoid schizophrenia, residual schizophrenia, undifferentiated schizophrenia, and catatonic schizophrenia per the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). In 2013 the American Psychiatric Association (APA) combined all the subtypes under the general category of schizophrenia. "Catatonia" is a word that has undergone multiple definitions and loosely is associated with multiple psychomotor...

  • The polysemous concepts of psychomotricity and catatonia: A European multi-consensus perspective
    by Jack R Foucher on December 23, 2021

    Current classification systems use the terms "catatonia" and "psychomotor phenomena" as mere a-theoretical descriptors, forgetting about their theoretical embedment. This was the source of misunderstandings among clinicians and researchers of the European collaboration on movement and sensorimotor/psychomotor functioning in schizophrenia and other psychoses or ECSP. Here, we review the different perspectives, their historical roots and highlight discrepancies. In 1844, Wilhelm Griesinger coined...

  • An outline of the catatonia concept of the Wernicke-Kleist-Leonhard school of psychiatry
    by Gábor Ungvári on November 5, 2021

    Following Wernicke and Kleist's footsteps, Karl Leonhard developed a detailed nosology of psychomotor disturbances occurring in endogenous/functional psychoses. In Leonhard's classification the good prognosis cycloid motility psychosis is distinguished from the group of systemic and non-systemic catatonic schizophrenias. The diag - no sis of both types of catatonic schizophrenias is based on the recognition of a specific catatonic sign/symptom coupled with less specific, yet relatively stable...
