IN THE NEWS: The function of memory is not fully understood by scientists, but researchers have some useful insights into why we can't remember everything.

“Having a ‘perfect memory’ can lead to redundant information, an inability to cope with adversities in life due to persistent memory, and an unnecessary increase in the energy requirement for the brain that already consumes 20% to 25% of whole-body energy."

Sajjadi is also an associate professor of neurology and chief of the Memory Disorders Division at the UCI School of Medicine.

A clinician scientist who studies neurodegenerative pathologies across the aging spectrum, his research focus includes Alzheimer's disease, primary progressive aphasia, frontotemporal dementia and dementia in the oldest adults.

Sajjadi is the recipient of multiple National Institutes of Health grants and the author of numerous studies that have appeared in prominent medical journals. He is also the recipient of the inaugural Joan and Don Beall Scholar Award given by the UCI Institute for Memory Impairments and Neurological Disorders (UCI MIND).
