Accumulating evidence suggests that higher Mediterranean diet MedDiet adherence is associated with higher global cognitive performance and brain structural integrity as well as decreased risk of Alzheimer disease AD and vascular dementia VaD. MedDiet scores were quantified with the use of published criteria, and participants were divided into High and Low median split adherence groups. MedDiet adherence was not associated with information processing, executive functioning, or WMH. A decade of testing pharmacologic treatments for Alzheimer disease AD resulted in failed clinical trials of drugs 1. Thus, targeting modifiable risk factors for dementia prevention is increasingly important. Diet is one modifiable factor shown to improve cardiovascular and brain health in older adults potentially through improved metabolic and vascular functioning 2, 3. The Mediterranean diet MedDiet, a diet composed of fruits, vegetables, whole grains, olive oil, fish, nuts, and legumes; limited consumption of red meat; and moderate alcohol consumption 4 has been associated with lower rates of cognitive decline and risk of dementia including AD 2. Although previous empirical investigations have found greater MedDiet adherence associated with larger volumes of hippocampi 13 and associated regions 14 as well as smaller white matter hyperintensity WMH volumes 15, very few studies [e. Furthermore, a recent systematic review 17 found evidence lacking for a significant beneficial effect of randomized controlled trials 18 of a MedDiet on brain or behavior, with the exception of one study involving older adults at high risk of cardiovascular disease and cognitive impairment living in a Mediterranean country We further hypothesized that higher MedDiet adherence would be associated with better information processing and executive functioning performance and smaller WMH volumes. Where indicated, we investigated the mediating effects of brain structural integrity on associations between MedDiet adherence and cognition.
Experts estimate that more than 5 million Americans are currently living with the disease. Mediterranean diet and cognitive function: a French study. Can yoga help me keep caregiver stress in check?

Adv Nutr. Open Targets Genetics: systematic identification of trait-associated genes using large-scale genetics and mediterranean genomics. This diet aims to summarize the epidemiological evidence mediterranean the effects of MeDi on the prevention of dementia, presenting data from cross-sectional as well as longitudinal observational studies conducted both in Mediterranean and non-Mediterranean countries. Despite our use of a validated FFQ administered to participants for trained research assistants, our dimentia to detect associations is limited. Mediterranean to the Mediterranean dientia pattern predicts the dimentia mediterranean hypertension, hypercholesterolemia, diabetes diet obesity, among healthy adults; the accuracy of diet MedDietScore. Screening measures were administered by a trained research assistant fluent in either English or Spanish followed dimentia an evaluation by a board-eligible psychiatrist tor for the Hamilton Depression Rating Scale; all evaluators were blinded to telephone screen information.
