Hippocampal Atrophy is the Most Robust Marker for Dementia
Duara et al., Neurology 71:1986–92, 2008
Main Factors Contributing to Atrophy in Hippocampus
• “Plaques” and “Tangles”
• Inflammation
• Concussion/TBI
• Vascular disease (obesity, OSA, hypertension, diabetes, CHF, CAD, A Fib, strokes)
• Depression(anxiety, stress, PTSD)
Plaques and Tangles

Sleep Apnea Shrinks Hippocampus

Obesity Shrinks Hippocampus
Associated with reduced brain volume
Ward, et al., 2005
Slows cognitive function
Debette, et al., 2011
Brains of overweight and obese individuals appeared 8 and 16 years older, respectively
Raji, et al., 2010

Stress Shrinks Brain Cells in Hippocampus

Depression Shrinks the Brain
The number of days of depression is associated with the severity of hippocampal atrophy
Sheline, et al, (1996). PNAS, 93(9);3908-13.
Depression is associated with impaired memory, executive function and processing speed
Egger et al, (2008). Psychiatry Research: Neuroimaging; 164(3): 237-44)
Sheline, (1996). PNAS, 93(9);3908-13.
