(NEWSER) - Vitamin B12 deficiency can cause memory loss, particularly in the elderly, reports the BBC.

The biggest risk factor is having a low level of education, which researchers say is linked to almost a fifth of cases worldwide. More»

(NEWSER) - High cholesterol in middle age may increase a person’s future risk of Alzheimer’s disease, NPR reports. “Our study shows that even moderately high cholesterol levels in your 40s puts people at greater risk for Alzheimer's disease and vascular dementia in later life,” says one researcher, who worked on a study of nearly 10,000 people that began in the 1960s.
