Research Summary

My primary scientific interest concerns disturbances of personality. Over the past several years, my research activity has focused on the nature of personality disturbances consequent to development of a brain disorder, and issues regarding the assessment of acquired personality disturbances (APD). The method employs the Iowa Scales of Personality Change (ISPC) to obtain ratings of patients from family members with identified neurological conditions. Recent and current projects have investigated APD associated with damage to prefrontal cortex or associated with specific conditions such as behavioral variant-frontotemporal dementia, amyotrophic lateral sclerosis and traumatic brain injury, as well as personality changes associated with normal aging and their functional consequences. Ongoing investigation also aims to identify and validate specific subtypes of personality disturbance resulting from brain damage.
