Nocturnal sleep apnea/hypopnea is associated with lower memory performance in APOE epsilon 4 carriers NEUROLOGY O'Hara, R., Schroder, C. M., Kraemer, H. C., Kryla, N., Cao, C., Miller, E., Schatzberg, A. F., Yesavage, J. A., Murphy, G. M. 2005; 65 (4): 642-644

Abstract

The authors investigated the relationship between obstructive sleep apnea/hypopnea (OSAH) and cognition in 36 older adults, 18 APOE epsilon4 carriers, and 18 non-carriers. Greater numbers of respiratory events negatively impacted memory function in epsilon4 carriers only. This is the first study to provide preliminary evidence for a negative interaction of APOE epsilon4 and OSAH on memory in older adults, which may have important implications for treating cognitive decline and delaying dementia onset.
