The effect of regular exercise on cognitive functioning and personality was investigated in 32 subjects representing 4 discrete groups based on sex and age. Before and after a 10 week exercise programme of jogging, calisthenics, and recreational activities, a test battery was administered to assess functioning in a number of domains: intelligence (WAIS Digit Symbol and Block Design); brain function (Trail-Making); speed of performance (Crossing-Off); memory and learning (WMS Visual Reproduction and Associate Learning); morale and life satisfaction (Life Satisfaction and Control Ratings); anxiety (MAACL); and depression (MAACL). Improvement was observed on several physiological parameters. ANOVA revealed significant sex and age differences on Digit Symbol and Block Design and age differences on Trail-Making, Crossing-Off, Associate Learning, and anxiety. Regardless of sex and age, significant improvement in performance was observed from pre to post-test on Digit Symbol, Block Design, Trail-Making, Crossing-Off, and on Associate Learning. In addition, an increase on health status rating (p less than .01) and decrease in anxiety were observed from pre to post-test. These data illustrate beneficial effects of exercise on certain measures of cognitive functioning and personality.

One hundred and three patients treated for endogenous depression with unilateral, non-dominant ECT, half with two, half with four treatments weekly, were examined to determine the effect of the treatment on memory functions. Th first-mentioned group was studied with double-blind technique in connection with an earlier study while the latter group was investigated under open conditions. Tests were made before the first treatment, after the sixth treatment, and after the final treatment (the Wechsler Memory Scale Forms I and II) and at the same times, ratings were made of the depressive state. No significant differences were found between the results of the two groups either with regard to the total results or the sub-test results in WMS. This was true for changes between and the first and the sixth treatment and between the first and the final treatment. On the whole, both groups showed improved results during the course of treatment; a memory reduction to an equal degree in both groups evident before treatment, and thus due to the depression, was eliminated concurrently with the improvement in the depressive condition. With reference to delayed reproduction a comparison made after the sixth treatment showed that the high-frequency treatment group scored significantly higher than the other group. This can only be ascribed to a better therapeutic effect resulting from accelerated treatment. Likewise these improved therapeutic results in the high-frequency treatment group must be responsible for the fact that this group does not show poorer test results than the group treated at the customary frequency-rate in spite of an expected deteriorating effect of accelerated treatment on memory functions and in spite of a larger number of treatments per series in this group. Neither in the higher nor in the lower frequency treatment group were any age-related variations in memory found.

The study reported comprised 104 patients with endogenous depression who were given unilateral electroconvulsive therapy (ECT). The patients were divided into two equally large groups, one receiving two and the other four treatments per week. The latter group was selected openly, while the former had been collected by a double-blind technique on a previous occasion. The severity of depression was assessed before the first treatment and on the days after the sixth and the last treatment, and at these times memory testing by WMS Forms I and II and EEG were also performed. An analysis is presented of the therapeutic effect obtained, assessed by: (1) the number of treatments applied in the two groups; (2) the reduction in the depression score; and (3) the effect achieved per treatment. In the group with frequent electrostimulation one to two addititional treatments were required, the difference being statistically significant. On the other hand, frequent stimulation tended to be more effective in terms of the reduction in the depression score. The effect per treatment was identical in the two groups. Four treatments per week did not result in a higher frequency of complications. A comparison of the five severest depressions in each of the two groups did not reveal any difference in the therapeutic effect of the two methods of treatment. It is concluded that the technique with four treatments per week instead of two offers the advantage that the duration of the treatment period is reduced by 11-12 days. As the study also revealed that the discomforts, including memory impairment, are not increased by frequent stimulation, it is recommended that unilateral ECT is administered with a frequency of four treatments per week.

The relation of specific MMPI scores to attention, concentration, and memory was assessed in an inpatient psychiatric sample diagnosed by DSM-III-R criteria as having schizophrenia, chronic undifferentiated type (n = 22); schizophrenia, paranoid type (n = 17); and schizoaffective disorder (n = 20). MMPI indices that are used widely to infer cognitive efficiency--including Scales 2 (Depression), 8 (Schizophrenia), SC-PT, D4 (Mental Dullness), SC2A (Lack of Ego Mastery, Cognitive), PSY (Psychoticism) and ORG (Organic Symptoms)--were investigated in relation to actual performance on Digit Span and subtests of the Wechsler Memory Scale (WMS, Russell's Revision). Weak correlations emerged (maximum r = .31, p less than .05), which suggests that scores on these MMPI measures may not provide a reliable basis for inferring attention and memory functioning.

54 patients with idiopathic Parkinson's disease (PD), 26 patients with Alzheimer's disease (AD) and 18 control subjects, all over 55, have performed neuropsychological tests, evaluating global intellectual function (Rosen's cognitive scale, WAIS digit symbol, WAIS similitude and WMS logical memory tests) and visuospatial functions (Rey lacunar pictures, Poppelreuter and Benton line orientation tests). AD group results were distinctly different from those of the PD and the control groups (p less than 0.001). In the PD group, only the Rosen's scale total score and the visuospatial tests were slightly altered (p less than 0.05). In a PD subgroup with a normal Rosen's scale result, the Benton line orientation test was different from controls (p less than 0.05). In another PD subgroup with Rosen's scale score comparable to a midly impaired AD subgroup, all the neuropsychological tests were abnormal. Only the WAIS digit symbol test, altered in this PD subgroup, was different comparing these 2 subgroups (p less than 0.05). With regard to the PD total group, the neuropsychological perturbed PD subgroup was older, had a longer duration of disease, a higher depression's score, less tremor and a worse equilibrium. These results might reflect a neuropsychological defect heterogeneity among PD patients, related to various pathophysiological hypothesis which are discussed in this paper.

Self-appraisal of cognitive difficulties by a sample of 63 male patients with closed-head injury (CHI) was examined in relation to their performance on the Wechsler Memory Scale - Revised (WMS-R; Wechsler, 1987), WAIS-R Digit Span (Wechsler, 1981), and to their scores on MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) measures of anxiety and depression. In an initial step, the Cognitive Difficulties Scale (CDS; McNair & Kahn, 1983), consisting of 39 self-report items, was factor analyzed using a sample of 255 consecutive neuropsychological referrals with documented brain impairment. Seven orthogonal dimensions emerged: Attention and Concentration, Orientation and Memory, Praxis, Domestic Activities, Facial Recognition, Task Efficiency, and Errand and Name Recall. Within a sample subset consisting of 63 patients with CHI, subjective complaints on the CDS were predictive of WMS-R Logical Memory performance (r = -.51, p < .0005). In contrast, CDS scores were generally poor predictors of Digit Span and Visual Reproduction scores (rs < .31). Cognitive complaints were also associated with emotional distress on the MMPI-2. The CDS appears to be a useful measure of self-appraised cognitive difficulties in patients with CHI, and may assist in the assessment of their self-reflective insight.

This study examined the contribution of neuropsychological functioning to the attainment of treatment objectives in substance abuse patients. Subjects were 85 patients enrolled in comprehensive, inpatient and outpatient substance abuse treatment at a VA Medical Center. Most subjects were diagnosed with Alcohol Dependence or Abuse, and nearly half were seeking treatment for Cocaine Dependence or Abuse. After acute detoxification, but before beginning individualized treatment, subjects were administered a neuropsychological screening battery to assess cognitive functioning and affective status. They then attended a variety of daily group therapies. Each therapy group had its own set of specific treatment objectives; on each treatment day, group therapists rated each patient's attainment of the specific objectives for their group. Groups included Assertiveness Training (Levels I and II), Stress Management (Levels I and II), Social Skills Training, Job Skills, Relapse Prevention (Levels I and II), Leisure Planning, Leisure Skills, Occupational Therapy, and 12-Step Study. Stepwise multiple regression indicated that the best predictors of overall objective attainment were better attention (WMS-R Digits Backwards) and less depressive symptomatology (Beck Depression Inventory). These results suggest that attention and mood have a modest yet significant impact on the success of treatment interventions for substance abuse patients. Thus, evaluation of cognitive as well as affective factors in substance abuse patients might be helpful in designing and implementing specialized interventions to maximize the likelihood of treatment success.

Neuropsychological evaluations and sex hormone assays for 188 elderly, female nursing home residents (mean age: 87.8 years; standard deviation: 7.0 years) revealed inverse relationships for dehydroepiandrosterone (DHEA) blood levels and cognition scores based on the Mini-Mental State Exam and the Test for Severe Impairment, as well as for scores of the Immediate Recall, Copy, and Recognition tests of the Visual Reproduction subtest of the Wechsler Memory Scale-Revised (WMS-R; VR). A positive correlation between estrone and depression approached significance, as did the inverse relationships between the Recognition scores of the WMS-R; VR with androstenedione. These results and findings of others suggest that sex hormone actions in elderly women may differ from those in younger populations. A possible stress-related mechanism is also posited.

The University of Pennsylvania Smell Identification Test (UPSIT) and the Cross-Cultural Smell Identification Test (CC-SIT) were administered to nondemented Greek participants ranging in age from 49 to 88 years together with tests of verbal memory from the Wechsler Memory Scale-3rd Edition (WMS-III). The test scores of the sample administered the CC-SIT were compared with the test scores of the 12 analogous UPSIT items of the sample administered the UPSIT. The percent of individuals correctly identifying each of the odorants of the UPSIT and CC-SIT is reported, together with means and standard deviations (S.D.) of the total smell scores. UPSIT performance in both the full test and the 12 analogous items was associated with WMS-III Logical Memory I performance after accounting for the effects of age, education and gender. CC-SIT performance was associated with gender, score on the Beck Depression Inventory-II and Logical Memory I performance. The study shows that olfactory identification is associated with verbal memory in nondemented individuals after accounting for demographic variables.

The Wechsler Memory Scale-Revised (WMS-R) malingering indices proposed by Mittenberg, Azrin, Millsaps, and Heilbronner [Psychol Assess 5 (1993) 34.] were partially cross-validated in a sample of 200 nonlitigants. Nine diagnostic categories were examined, including participants with traumatic brain injury (TBI), brain tumor, stroke/vascular, senile dementia of the Alzheimer's type (SDAT), epilepsy, depression/anxiety, medical problems, and no diagnosis. Results showed that the discriminant function using WMS-R subtests misclassified only 6.5% of the sample as malingering, with significantly higher misclassification rates of SDAT and stroke/vascular groups. The General Memory Index-Attention/Concentration Index (GMI-ACI) difference score misclassified only 8.5% of the sample as malingering when a difference score of greater than 25 points was used as the cutoff criterion. No diagnostic group was significantly more likely to be misclassified. Results support the utility of the GMI-ACI difference score, as well as the WMS-R subtest discriminant function score, in detecting malingering.
