Memory assessment using the Strub-Black Mental Status Examination and the Wechsler Memory Scale

A systematic mental status exam often can differentiate accurately patients with organic brain disease from normal persons and those with functional disorders. The present study attempts to validate the memory portion of the Strub-Black Mental Status Exam by comparing it to the Wechsler Memory Scale. Twenty-five brain-damaged and 25 routine medical patients were given Form I of the Wechsler Memory Scale and the memory portion of the Strub-Black Mental Status Exam at their hospital bedside. Results indicate significant differences in almost all scores between the brain-damaged and normal groups on both the Wechsler Memory Scale and Mental Status exam; the Mental Status Exam differentiated between groups at a higher level of significance of ANOVA and ANCOVA comparisons of total memory scores, as well as several subtests. In these samples, age, more than education, was an important factor that affected memory test performance. The Mental Status Examination appears valid for the differentiation of clinical samples and for the documentation of specific aspects of memory dysfunction in individual brain-damaged patients. This study represents a beginning step in providing normative data on components of the Strub-Black mental status examination.
