Early Alzheimer's patients 7 times likely to be 'lonely'
Loneliness could be a factor in Alzheimer's disease, with around 7.5 times higher likelihood of loneliness in early stage patients, according to a new Harvard study. The study found correlation between social isolation and raised levels of amyloid, a toxic brain plaque-building protein associated with Alzheimer's. However, the study does not reveal whether social isolation is a cause or effect.
