Subjective cognitive decline may reflect a dementia prodrome or modifiable risk factor such as sleep disturbance. What is the association between and subjective decline? Cross-sectional design, from two studies of older adults: WHICAP in USA HELIAD Greece. A total 1,576 1,456 participants, without mild impairment, severe depression/anxiety, were included. Participants mostly women, with 12 (WHICAP) 8 (HELIAD) mean years education. Sleep problems estimated using Scale Medical Outcomes Study....

Dietary intervention is an enticing approach in the fight against cognitive impairment. Nutritional supplements and dietetic counseling are relatively easy benign interventions, but research has not yet yielded irrefutable evidence as to their clinical utility. Heterogeneity results of available studies, well methodological practical issues, does allow replication generalization findings. The paper at hand reviews only randomized trials single nutrients, multi-nutrient formulations dietary...

Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent, acute, and self-limiting attacks of fever. Mutations in MEFV gene encoding pyrin account for FMF, but the high number heterozygote patients with typical symptoms has driven a alternative aetiopathogenic hypotheses.

Abstract Very few data are available regarding the association of adherence to Mediterranean Diet (MeDi) with Subjective Cognitive Decline (SCD) evolution over time. A cohort 939 cognitively normal individuals reporting self-experienced, persistent cognitive decline not attributed neurological, psychiatric or medical disorders from Hellenic Epidemiological Longitudinal Investigation Aging and (HELIAD study) was followed-up for a mean period 3·10 years. We defined our SCD score as number...
