A differential phenomenological study of acute and chronic schizophrenia is scanty. Thought disorder was assessed in 22 acute and 23 chronic schizophrenics. The scale for the assessment of thought, language and communication was used. Poverty of speech was significantly more frequent in acute schizophrenia. Positive formal thought disorder was unusually found to be severer in chronic schizophrenia. No other significant difference was found. From the perspective of thought disorder, acute and chronic forms of schizophrenia seem to be in a continuum with minimal difference.
Thought disorder was studied in 21 paranoid and 24 non-paranoid schizophrenics fulfilling the research diagnostic criteria using the Thought, Language and Communication Scale. Chronic paranoid schizophrenics more often had tangentiality. Other thought disorders were similar in paranoid and non-paranoid schizophrenics.
A patient with multiple psychosomatic disorder developed a steroid induced rare bipolar mood disorder (both mania and depression). The "unmasking effect" of steroids and a positive family history of psychiatric disorder as a possible risk factor, hitherto undocumented, is suggested in steroid induced psychosis.
Seasonal relapses of affective disorder are known. We report 12 patients who had season-linked relapses during a prospective follow-up period of 4 years. There were both winter and summer relapses of mania and depression. The centre is in the tropical zone, with lesser variation of sunshine and temperature than in more extreme latitudes. This may inference the pattern of relapse in affective disorder. Differences in relapses between tropical and temperate zones need to be investigated.
The correlation of clinical and demographic variables of thought disorder was studied in 45 Research Diagnostic Criteria (RDC) schizophrenics. Thought disorder was assessed by the scale for the assessment of Thought, Language and Communication (TLC). Negative thought disorder was significantly correlated with the rural background. Individual TLC items like Distractible speech, Illogicality, Clanging, Neologisms, etc. were correlated with the literate group and perseveration with the illiterate group. No significant correlation was noted between thought disorder and clinical variables.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
