Sleep Disordered Breathing and Alzheimer's Disease Biomarkers in Normal Aging and Mild Cognitive Impairment
Sleep Disordered Breathing and Alzheimer's Disease Biomarkers in Normal Aging and Mild Cognitive Impairment
The purpose of this study is to determine the sleep patterns of subjects with or without
 sleep disturbances (insomnia, sleep apnea) and compare these findings with their previous
 FDG/PIB PET, structural MRI and brain blood flow scams performed during their participation
 in the Following studies 'Alzheimer's Disease Core Center (ADCC) Clinical Evaluation' (IRB:
 2942), MRI Progression Markers of Cognitive Decline in the Elderly' (IRB:09-0586), or
 'Imaging Neuro inflammation in Alzheimer's Disease with [11C] Arachidonic Acid (AA) and
 PET'(IRB: 10-00442).
Inclusion Criteria:

 -  All subjects will have participated in prior CBH studies and have agreed to an FDG,
 PIB and MRI scans.

 Exclusion Criteria:

 -  Diagnosis of sleep apnea and under treatment with a continuous positive airway
 pressure (CPAP) machine.

 -  Active depressive episode during the evaluation with a Geriatric Depression Scale
 score >7 and/or a Clinical Global Impression scale for depression score >4.

 -  Moderate Cognitive decline (GDS >3).
