Quantitative measurement of delta activity in Alzheimer's disease.

Quantitative measurements of delta activity were made in 10 healthy elderly controls and 31 subjects with Alzheimer's disease. Delta activity did not discriminate between the healthy elderly controls and the early mild Alzheimer's disease subjects. However, delta activity was a significantly greater percentage of total EEG power in the moderate-to-advanced Alzheimer's subjects when compared to either the healthy controls or mild Alzheimer subjects. In the T3 and T4 electrodes, delta activity in the moderate-to-advanced Alzheimer subjects was 78.3% and 47.6% higher, respectively, than in control subjects. Furthermore, delta activity was an excellent predictor of dementia severity within the 31 subjects with Alzheimer's disease.

Transient global amnesia and thalamic infarction.

We describe the clinical and neuroradiologic features of a patient with two episodes of transient amnesia who later developed persistent amnesia and an acute infarction in the left thalamus. The neurobehavioral manifestations were strikingly similar in all three episodes. Cranial computed tomography was normal following the first two episodes. Thalamic ischemia could explain some cases of transient global amnesia.

Sex-role-related differences in self-concept and mental health.

Examined the differences in serf-concept and psychological health between androgynous, sex-typed, cross-sex-typed, and undifferentiated males and females. Two hundred forty-nine students who were enrolled in introductory psychology classes were classified according to sex type on the basis of their scores on the Bem Sex-Role Inventory. Nine aspects of self-concept and five aspects of psychological health, obtained, from the Tennessee Self-Concept Scale, were analyzed as a function of Sex and Sex Type. A series of analyses of variance and subsequent individual comparisons across groups revealed a clear pattern wherein androgynous subjects manifested more positive self-concepts and more positive psychological health than sex-typed subjects. Undifferentiated subjects manifested the poorest self-concepts, while results for sex-typed and cross-sex-typed subjects varied more as a function of the sex of the subject. The data are discussed as appearing to be consistent with Bem's hypothesis that androgynous people may represent a more appropriate societal definition of mental health than strongly sex-typed people. Qualifications of this support are also discussed.
