title: A study of bedside screening procedures for cognitive deficits in chronic psychiatric inpatients.
abstract: The Mini-Mental State Examination (MMSE) and the Trail Making Test, part B (TMT-B) were compared for screening cognitive deficits in a sample of 104 psychiatric inpatients at a long-term hospital. The TMT-B classified 84% of the patients as impaired. The classic MMSE cutoff score (< or = 23) using serial sevens and spelling classified 42% and 24% of the patients respectively, as impaired. The new MMSE cutoff classified 71% as impaired. Education, gender, and medication may influence impairment when using the MMSE classic cutoff scores. In TMT-B only, impairment was influenced by chronicity. The TMT-B was able to distinguish patients impaired in the MMSE. The TMT-B, therefore, may be more useful than the MMSE to screen for cognitive deficits in chronic psychiatric inpatients.
