4,500 people were tracked using 24-hour monitors for 7 days. Activity levels were studied to determine the effect on short-term memory, problem-solving, and processing skills. As little as six to nine minutes of moderate-to-vigorous activity when compared to sitting, sleeping, or gentle activities yielded higher cognition scores. Cognitive improvement was modest, but increasing time spent in energetic activity increased the measured benefits.

Factors evaluated were diet, exercise, social integration, cognitive activity, smoking history, and alcohol use. Participants were categorized as favorable (4-6 positive factors), average (2–3 positive factors), and unfavorable (0–1 positive factor). The “favorable” group had a a slower decline in cognition even if they were APOE e4 carriers.

The presence of vitamin D in the brain and its link to improved cognitive performance in aged subjects was originally discovered by a Tufts University study. Higher vitamin D concentrations were linked to a 25% to 33% decreased risk of dementia or mild cognitive impairment in four different brain areas. Authors did note, however, that the observational nature of the study and the lack of a diverse subject population were two of its drawbacks, and there may be further explanations for the results.

Gantenerumab treatment generated a slowing of clinical decline from baseline score on the Clinical Dementia Rating-Sum of Boxes (CDR-SB), but at levels that did not reach statistical significance. The relative reduction in clinical decline was 8% in GRADUATE I and 6% in GRADUATE II compared with placebo.

At the time of this study, in 2016, dementia was seen in 10% of those over age 65 in the US, and mild cognitive impairment (MCI) in 20%, with increased risk for every 5 year advance in age. Risk was 80% higher for non-Hispanic Black individuals and approximately 40% higher in Hispanic persons, compared with White individuals. Dementia and MCI were inversely correlated with years of education, though.

A Secondary Analysis of The N107C/CEC.3 (Alliance for Clinical Trials in Oncology/Canadian Cancer Trials Group) Randomized Clinical Trial When compared to WBRT, SRS alone resulted in less cognitive deterioration among long-term survivors. The link between late cognitive deterioration and WBRT was clinically significant. A significant decrease in cognition (2 SD) was linked to a decrease in overall QOL. WBRT, on the other hand, improved intracranial tumor control. This study provides detailed information about cognitive function in this patient population over time.
