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
Vascular Factors Zlokovic et al. Neurosurgery 43(4), 877–78, 1998
Sleep Apnea Shrinks Hippocampus Am J Respir Crit Care Med 2002; 166:1382–7 8
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., Brain Research Volume 1280, 14 July 2009, Pages 186–194
Stress Shrinks Brain Cells in Hippocampus Stress Control 14
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); Depression is associated with impaired memory, executive function and processing speed Egger et al, (2008). Psychiatry Research: Neuroimaging; 164(3): ) Sheline, (1996). PNAS, 93(9);
