NIH reviewed all research studies conducted during the past decade to identify any and all factors that might be associated with an increased risk of developing Alzheimer’s Disease or Cognitive Decline. Cognitive training was found to be correlated with a decreased risk of developing and/or progressing with Alzheimer’s Disease. According to the rigorous scientific standards established by NIH, this finding was said to be significant at a low level of scientific strength. Other factors associated with a decreased risk/progression of A.D. were similarly found to be significant at a low level of scientific strength, and no factors were identified at a high level.
The most striking finding in the NIH Review was that there was only one variable associated at a high degree of scientific strength with a decreased risk of developing cognitive decline: cognitive training.
