Perminder Sachdev is an internationally-recognised authority and leader in the field of neuropsychiatry. His research contributions to our understanding of drug-induced movement disorders, in particular akathisia and neuroleptic malignant syndrome, and the cerebrovascular basis of cognitive impairment and dementia, most especially vascular dementia and small vessel disease, have been groundbreaking. His most recent focus on identifying the risk and protective factors for dementia has been equally pioneering. Given his exceptional contributions across research, clinical practice, community engagement and advocacy, as well as his leading national and international profile, Perminder Sachdev is a most worthy candidate for election the AAHMS Fellowship.
