The role of diet in cognitive decline
Solfrizzi V, Panza F, Capurso A.. Journal of neural transmission (Vienna, Austria : 1996), 2003-01-01
Topic: Risk, prevention and care in population studies
Recent findings suggest a possible role of diet in age-related cognitive decline, and cognitive impairment of both degenerative (Alzheimer's disease, AD) or vascular origin. In particular, in an older population of Southern Italy with a typical Mediterranean diet, high monounsaturated fatty acids energy intake appeared to be associated with a high protection against cognitive decline. In addition, dietary fat and energy in older people seem to be risk factors, while fish consumption and cereals are found to reduce the prevalence of AD in the European and North American countries. Moreover, foods with large amounts of aluminium-containing additives or aluminium from drinking water may affect the risk of developing AD. Vitamin deficiencies, especially vitamin B6, B12 and folates, and antioxidant deficiencies (vitamins E and C) could also influence the memory capabilities and have an effect on cognitive decline. Dietary anti-oxidants and supplements and specific macronutrients of the diet may act synergistically with other protective factors opening new possibilities of intervention for cognitive decline.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
