flow to mean occipital flow for each ROI were compared between the two diagnostic groups. No significant difference between groups was found for any region on either measure. Neuropsychological test results were grouped into five general and eight specific functional groupings supported by previous factor analytic studies (e.g., Horn, 1990). Generalized cerebral functions included overall intelligence, attention and concentration, incidental memory, abstract reasoning, and overall brain functioning. Specific cerebral functions included specific intelligence, previous learning, memory, sensory input, motor output, language, and constructional abilities. Multivariate analyses indicated no significant differences between the groups on any of the functional groupings. Similar patterns of cortical metabolism and function were present for the two groups. A discussion of the current distinction between possible and probable AD will be presented. Warner, M. S., Gouvier, W. D., Prestholdt, P. H., & Petito, P. M. Louisiana State University. A Survey of Common Misconceptions about Cerebrovascular Accidents and Recovery. A survey questionnaire composed of 30 statements about stroke and recovery was administered to 202 individuals at a large, regional shopping mall. Survey items were categorized into domains pertaining to causes of stroke, effects of stroke, the role of family and friends in rehabilitation, and recovery from stroke. Additional survey items inquired about the sources from which people obtained their knowledge, extent of personal experience with stroke, occupational status, and residential status. Results indicate that misconceptions exist across all areas of the questionnaire and were most substantial in the areas of causes, effects, and rehabilitation of CVA. These findings corroborate clinical observations of gross misconceptions reported in the literature. Specific misconceptions appeared with comparable frequencies across the age groups studied, which indicates that family education for patients in rehabilitation needs to target all members of a family, rather than a designated primary caregiver.

Differences in Cognitive Function, Cerebral Anatomy and Metabolism in Monozygotic Twins Concordant for Alzheimer’s Disease. Twin studies of Alzheimer’s disease (AD) allow estimation of possible heritable and environmental contributions to the condition. In our pilot studies of AD in the NAS Registry of World War II veterans, one pair of monozygotic twins was identified as concordant for probable AD (NINCDS-ADRDA criteria), showing similar ages of disease onset (61 proband; 60 co-twin) but markedly different neurobehavioral syndromes. The proband had typical AD symptoms of an amnestic syndrome with additional deficits in language and executive functions. His co-twin presented with a complex visual disturbance
