My answer to Is there any existing research on genetic architecture linking autism, alzheimer's and anorexia?

Answer by Connie b. Dellobuono:

Brain plasticity of people with autism may protect them from Alzheimer's disease, scientists propose.

Autism may carry a benefit: a buffer against Alzheimer’s

From Wiki:

In regard to mental health, individuals with eating disorders appear to have memory impairments in executive functioning, visual-spatial ability, divided and sustained attention, verbal functioning, learning, and memory.

Some memory impairments found in individuals with ED, are due to nutritional deficiencies, as well as various cognitive and attentional biases. Neurobiological differences have been found in individuals with ED compared to healthy individuals, and these differences are reflected in specific memory impairments.
