Mild Cognitive Impairment Clinical Trial
Official title:
Examining the Impact of Grape Consumption on Brain Metabolism and Cognitive Function in Patients With Mild Cognitive Impairment
Constituents of grapes have been studied for their antioxidant, anti-inflammatory, and anticarcinogenic properties. In the past decade, there has been emerging evidence regarding a potential role for grapes in slowing cognitive decline and other effects of aging. Furthermore, evidence has been obtained in vivo that supplementation of aged rats with grape seed extract improves cognitive performance. Despite the promising accumulating data supporting the use of grapes as a safe and effective strategy for delaying the incidence of dementia, it remains unclear how grape intake would be useful with respect to factors such as dose schedule or stage of dementing illness. In general, well-controlled experimental data obtained in human subjects is in need of much further development. The investigators aim to measure effects of grape intake on cerebral metabolism and cognitive function, and to determine whether initial patterns, and magnitude of change, of cerebral metabolism assessed by positron emission tomography (PET) can serve respectively as a predictor of, and biomarker for, the magnitude of cognitive changes resulting from intake of grapes.

Eligibility |
Inclusion Criteria: - Cognitive deficit and/or personality change is present, as observable by physician and/or close contact(s) of the patient; or in the absence of this, the patient provides a clear history of decline which the patient's physician deems to be reliable. - If history or neurologic exam reveals findings suspicious for stroke, tumor, bleed, ictal activity, or hydrocephalus, then CT/MRI and appropriate neurological or neurosurgical consultation must have been obtained. - Standard history, physical, and laboratory screen have been performed to identify possible presence of depression, substance abuse, malnourishment, medication effects and interactions, cardiopulmonary compromise, electrolyte/calcium imbalance, anemia, hypoxemia, infection, thyroid dysfunction, renal dysfunction, hepatic dysfunction, or glucose dysregulation. - Any positive findings revealed in 2) or 3) above have been appropriately treated, wherever possible, but cognitive/behavioral deficit persists post-therapy. Exclusion Criteria: - Subjects under age 65 will not be recruited, in order to enhance the clinical relevance of the project by focusing on the age groups in whom serious concerns about early signs and symptoms of senile onset dementia are most typically emerging. - Already diagnosed with Alzheimer's disease or other cause of dementia - Cognitive dysfunction has impaired subject's ability to perform activities of daily living. - Present or past history of thyroid disease (due to effects of both the disease and thyroid hormone replacement therapy on brain metabolism that we and others have begun to identify, but which remain incompletely characterized.) - Claustrophobia or metal in body or other condition that would preclude PET or MRI from being acquired, or visual, auditory or motor deficits that would preclude accurate neuropsychological testing. - Currently receiving medication used specifically to treat Alzheimer's disease or other dementia-related disorder |
