HIV-associated dementia occurs in around 30% of untreated HIV-positive patients. Surprisingly, it also is occasionally found in some patients (2-3%) who are being successfully treated for HIV (and show no signs of AIDS).
Two years ago, I reported on a clinical trial of a nutrient cocktail called Souvenaid for those with early Alzheimer’s.

Following on from mouse studies, a human study has investigated whether caffeine can help prevent older adults with mild cognitive impairment from progressing to dementia.
