Brain-Age quotient: age and education correlates.

The Brain-Age Quotient (BAQ) of Reitan has been proposed as a means of studying age-related cognitive differences. This study examined age and education correlates of the BAQ and a BAQ short form. A heterogeneous group of 100 subjects were selected from the neuropsychological testing case records published by Golden, Osmon, Moses, and Berg in 1981, Boll (undated), and Reitan (undated). Results suggest the BAQ and the BAQ short form are not significantly correlated with age and education.

Neuropsychological practice effects x age: a brief note.

This is a brief review of some literature on practice effects and age on neuropsychological testing. Research suggests that younger subjects show greater improvement when retested on intelligence tests than older persons. The implication is that the effects of neuropsychological practice may vary with the age of the person assessed. Suggestions for further research are discussed.

Demographic and intellectual correlates of the Short-term Memory Test.

This study examined the effect of demographic variables and intellectual factors on the Short-term Memory Test. Subjects were 20 patients neurologically diagnosed as brain-damaged. There was only one significant correlation between Verbal IQ and the Short-term Memory Test. Demographic variables of age, education, and sex did not correlate significantly with scores of the Short-term Memory Test.

Attention deficit disorder, alcoholism, and drug abuse: MMPI correlates.

Earlier research had demonstrated that alcoholics with attention deficit disorder residual type (ADDRT) differ from other alcoholics on the Minnesota Multiphasic Personality Inventory (MMPI). The purpose of this study was to explore the influence of drug abuse on the relationship of ADDRT and alcoholism as reflected on the MMPI. Groups of 48 male alcoholics, 28 ADDRT alcoholics, 25 ADDRT alcohol and drug abusers and 18 alcohol and drug abusers were all administered the MMPI. Significant differences were found between the alcoholic and ADDRT alcoholic groups on scales Pd, Sc, Si, F, and K. For the ADDRT alcohol and drug abusers versus the alcohol and drug abuser groups, they differed on scales K, Hs, D, Pd, Pa, Pt, Sc, Si, F, K, and L.

Computerized interpretation of the Luria-Nebraska Neuropsychological Battery: a pilot study.

Programs for the computer analysis and interpretation of neuropsychological test data have been developed in recent years. In this paper, a new computer program, with initial validation data, is presented. Diagnostic hit rate for brain damage was 80% (52 of 65). For the extent of brain damage the hit rate was 60% (12 of 20). When laterality was considered, the hit rate was 71% (10 of 14). These results are comparable with computer programs for data from the Halstead-Reitan Neuropsychology Test Battery.

Validation of the Mini-Mental State Examination.

The present study examined the concurrent neuropsychological validity of the Mini-Mental State Examination (MMS). In this study the Luria-Nebraska Neuropsychological Battery (LNNB) served as a measure of neuropsychological ability. A sample of 20 patients was all administered the MMS and LNNB. Results demonstrate the highest correlation with the MMS for the LNNB expressive language, arithmetic, writing, motor and tactile scales.

Comparison of multiple sclerosis and head trauma patients: a neuropsychological pilot study.

This paper reports the comparison of multiple sclerosis and head trauma patients on a battery of neuropsychological tests. Age-matched groups of 4 multiple sclerosis and 4 head trauma patients were administered the Wechsler Adult Intelligence Scale--Revised (WAIS-R), the Weschler Memory Scale (WMS) and Category and Tail Making Tests (TMT) from the Halstead Reitan Neuropsychological Test Battery. Statistically significant results between groups were found on all variables with the strongest difference on the Category test and WMS (p less than .01). The concept of cortical vs. subcortical dementia could be used to explain these differences between groups of multiple sclerosis and head trauma patients.

The construct validity of the Four Word Short-Term Memory Test: a preliminary study.

Recent research with the Four Word Short-Term Memory Test (STMT) has suggested that it may provide information useful in the clinical setting. The present study evaluated the construct validity of the STMT. Twenty subjects were administered the STMT in addition to the Wechsler Adult Intelligence Scale and the Wechsler Memory Scale. As expected, performance on the STMT was significantly correlated with both Memory Quotient and Verbal Intelligence Quotient. A stepwise linear regression analysis suggested a trend toward significance for the relationship between the STMT and MQ, after accounting for the influence of Verbal Intelligence Quotient. The data suggest the need for a verbal intelligence correction when using the STMT clinically.
