From a Wall Street Journal online article:
Mr. Chambers, a 48-year-old physical therapist in Jersey City, N.J., modified his sleep, diet and exercise routines. Eighteen months later, his performance on a battery of cognitive tests improved, particularly in areas like processing speed and executive function, such as decision-making and planning.
Most surprising, says Dr. Isaacson, is that the MCI patients who followed at least 60% of their recommendations showed cognitive improvement. However, MCI patients who followed less than 60% of the recommendations experienced cognitive declines similar to the control groups, he notes.
Mr. Chambers is among 154 patients in a study, published Wednesday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, that doctors say shows encouraging results. Among healthy patients, people who made changes in nutrition and exercise showed cognitive improvements on average. People who were already experiencing some memory problems also showed cognitive improvement—if they followed at least 60% of the recommended changes.

“We found staggering inconsistencies between how costs of dementia are calculated across studies and our analysis strongly supports that current estimates fail to recognise the true costs of the diseases, such as Alzheimer’s, that cause dementia. Some studies have estimated that out of pocket expenses for people with dementia are up to one third of their household wealth in the final five years of their life, and that caregivers have healthcare costs that are twice as high as non-caregivers. We also found evidence that costs begin rising up to 10 years prior to diagnosis — we need to better measure and factor all these into future societal cost estimates.”
