Each recommendation is identified as falling into one of three categories of endorsement, indicated by a bracketed Roman numeral following the statement. The three categories represent varying levels of clinical confidence regarding the recommendation: [I] Recommended with substantial clinical confidence. [II] Recommended with moderate clinical confidence. [III] May be recommended on the basis of individual circumstances.

Practice Guideline for the Treatment of Patients With Bipolar Disorder (Revision)

OBJECTIVE: The authors assess the present position of catatonia in diagnostic classification systems and consider the merits of designating catatonia as a separate diagnostic category with defined criteria. METHOD: Following the logical steps to establish diagnostic validity when the etiology of a syndrome is unknown, the authors review the literature on the features that delineate catatonia as a syndrome, the prevalence and response to treatment of catatonia, and the conditions that are associated with catatonia. RESULTS: Catatonia is a well-defined syndrome that can be reliably ascertained. Although more than 40 motor signs of catatonia are known, the presence of two prominent features for 24 hours or longer is sufficient to identify the syndrome. Catatonia is found in about 10% of acutely ill psychiatric inpatients and is more commonly observed in persons with mood disorder than in those with schizophrenia. It is found in many conditions and presents mainly as retarded-stuporous or excited-delirious fo...

Catatonia in Psychiatric Classification: A Home of Its Own

These guide lines for the biological treatment of schizophrenia were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBO). The goal during the development of these guidelines was to review systematically all available evidence pertaining to the treatment of schizophrenia, and to reach a consensus on a series of practice recommendations that are clinically and scientifically meaningful based on the available evidence. These guidelines are intended for use by all physicians seeing and treating people with schizophrenia. The data used for developing these guidelines have been extracted primarily from various national treatment guidelines and panels for schizophrenia, as well as from meta-analyses, reviews and randomised clinical trials on the efficacy of pharmacological and other biological treatment interventions identified by a search of the MEDLINE database and Cochrane Library. The identified literature was evaluated with respect to the strength of evidence for its efficacy and then categorised into four levels of evidence (A-D). This first part of the guidelines covers disease definition, classification, epidemiology and course of schizophrenia, as well as the management of the acute phase treatment. These guidelines are primarily concerned with the biological treatment (including antipsychotic medication, other pharmacological treatment options, electroconvulsive therapy, adjunctive and novel therapeutic strategies) of adults suffering from schizophrenia.

The comorbidity of bipolar and anxiety disorders: prevalence, psychobiology, and treatment issues.

Differential diagnosis of motor symptoms, for example, akinesia, may be difficult in clinical neuropsychiatry. Symptoms may be either of neurologic origin, for example, Parkinson's disease, or of psychiatric origin, for example, catatonia, leading to a so-called "conflict of paradigms." Despite their different origins, symptoms may appear more or less clinically similar. Possibility of dissociation between origin and clinical appearance may reflect functional brain organisation in general, and cortical-cortical/subcortical relations in particular. It is therefore hypothesized that similarities and differences between Parkinson's disease and catatonia may be accounted for by distinct kinds of modulation between cortico-cortical and cortico-subcortical relations. Catatonia can be characterized by concurrent motor, emotional, and behavioural symptoms. The different symptoms may be accounted for by dysfunction in orbitofrontal-prefrontal/parietal cortical connectivity reflecting "horizontal modulation" of cortico-cortical relation. Furthermore, alteration in "top-down modulation" reflecting "vertical modulation" of caudate and other basal ganglia by GABA-ergic mediated orbitofrontal cortical deficits may account for motor symptoms in catatonia. Parkinson's disease, in contrast, can be characterized by predominant motor symptoms. Motor symptoms may be accounted for by altered "bottom-up modulation" between dopaminergic mediated deficits in striatum and premotor/motor cortex. Clinical similarities between Parkinson's disease and catatonia with respect to akinesia may be related with involvement of the basal ganglia in both disorders. Clinical differences with respect to emotional and behavioural symptoms may be related with involvement of different cortical areas, that is, orbitofrontal/parietal and premotor/motor cortex implying distinct kinds of modulation--"vertical" and "horizontal" modulation, respectively.

What catatonia can tell us about "top-down modulation": a neuropsychiatric hypothesis.

Objective:The authors reviewed the recent literature regarding the treatment of catatonia as a syndrome of multiple etiologies. Given the historical and clinical association of catatonia with schizophrenia, the authors' examined the assumption that the first-line treatment of catatonia is antipsychotic medication.Methods:Articles published between January 1, 1985 and December 31, 1994 were located using the Paperchase® medical literature search system. Additionally, references from those identified articles were examined for possible inclusion in this review. To be included in this review, articles had to be written in English and report specific symptoms of catatonia to determine, retrospectively, if DSM-IV criteria for catatonia were met.Results:Seventy publications met inclusion criteria and reported on a total of 178 patients and included 270 separate treatment episodes. Most of the articles were case-reports, although a few case-series were identified. Multiple causes of catatonia were identified in ...
