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.

The findings point to the possibility of very early detection of dementias, when recruitment into preventive trials, drug trials, and implementation of preventive strategies to slow the disease have the most impact.

In the confirmatory trial, Clarity AD, of 1,795 patients with early AD, findings showed a reduction of dementia scoring of 27% vs. placebo. These findings were seen as early as 6 months.

Palliative care (PC) can help reduce emergency department use, hospitalizations, and symptom burden across a spectrum of diseases. To assist clinicians in keeping their expertise current, the authors reviewed and summarized the top PC articles of 2020. The analysis included 28 PC intervention trials for heart failure, chronic obstructive pulmonary disease, and dementia.

The optimal dose of daily steps—the amount with the greatest dementia risk reduction—was 9,826 steps, with the minimum step dose, or the amount at which dementia risk was half of the maximal reduction, was 3,826 steps per day. See the original article on JAMA Neurology.

Among 150 people ages 65 to 88, investigational transcranial alternating current stimulation for 20 minutes over 4 consecutive days produced selective improvements in working and long-term memory in older adults that lasted for at least a month The rate of memory improvement over 4 days predicted the size of memory benefits 1 month later, the researchers found. Moreover, people with lower baseline cognitive function experienced larger and longer lasting memory improvements. “We found that by applying extremely weak electrical current safely and noninvasively to the prefrontal cortex at a high frequency, we could selectively improve long-term memory in older people aged 65 to 88 years old without changing short-term memory.” Robert Reinhart, PhD, Boston University in Nature Neuroscience
