Neuropsychology Research

Research Collaborations

Our team is actively involved in multiple research collaborations. Studies we currently participate in include:

StrokeCog: Stanford Stroke Recovery Program
This is a longitudinal study utilizing serial neuropsychological assessments to examine associates between immunological responses and long-term post-stroke cognitive trajectories in individuals with ischemic stroke.

Stanford Alzheimer’s Disease Research Center
The Stanford Alzheimer’s Disease Research Center (ADRC) serves as a shared resource to promote, enable, and enhance interdisciplinary and multidisciplinary research on Alzheimer’s disease and Alzheimer’s disease related dementia. The Clinical Core of the Stanford ADRC recruits and follows patients with Alzheimer’s disease, Parkinson’s disease, dementia with Lewy bodies, and mild cognitive impairment; and healthy older volunteers without neurological disease or cognitive impairment.  Information that we collect supports innovative research on understanding fundamental causes of neurodegenerative disease and enabling early identification, effective treatment, and prevention.

Stanford Aging and Memory Study (SAMS)
This study examines individual differences in memory and predictors of memory decline.

Experimental Study of Goal-Directed Behavior and Memory During Temporal Lobe Epileptic Activity
This study investigates how epileptic activity effects memory encoding and consolidation in patients with temporal lobe epilepsy

Clinical and Genetic Characterization of Myotonic Dystrophy
This study explores cognitive impairments in individuals with myotonic dystrophy
