| Annotation | 128 patients referred to Worthing Priority Care (NHS) with a differential diagnosis of pseudodementia were screened using a checklist of 44 characteristic features (in the form of questions with Yes or No answers) which the literature claimed to differentiate between organic dementia and depressive pseudodementia. This checklist covers the areas of history, clinical data, insight and performance. Forty points (questions) out of 44 in the checklist showed significant discriminating power to differentiate dementia from depressive pseudodementia. A principal component and factor analysis was performed from which 18 questions were extracted. The shortened questionnaire was able to classify (43/44 cases) 98% of dementia cases and (60/63) 95% of depression correctly. A new definition has been introduced for pseudodementia as a syndrome of reversible subjective or objective cognitive problems caused by non-organic disorder. Depressive pseudodementia may be classified into two subtypes: Type I - has depressive symptoms with subject complaint of dysmnesia with measurable intellectual deficits; and Type II - has depressive symptoms and shows poor cognitive performance based on poor concentration not due to organic disorder.
