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.

In this study, higher levels of omega-3s were linked with larger hippocampal volumes and improved cognition, and the increases seen continually with each step measurement of the omega-3s. All measured omega-3 predictors were tied to better abstract reasoning test scores. Participants in the top three quartiles of EPA levels had better abstract reasoning performance than those in the bottom EPA quartile. The associations remained after adjusting for vascular risk factors.

An observational analysis reviewed 54 studies and two medical record databases with data for 1.2 million individuals, to determine how many people experienced at least 1 of the 3 self-reported Long COVID symptom clusters 3 months after infection. The results indicate a Long COVID rate of 6.2%: 3.7% for ongoing respiratory problems, 3.2% for persistent fatigue with bodily pain or mood swings, and 2.2% for cognitive problems.

On September 20, 2022, Alzheon Inc. announced promising results from its phase 2 trial of oral ALZ-801 (valiltramiprosate) in patients with early AD. The drug decreased p-tau181 levels, reduced brain atrophy, and improved cognitive skills in the trial.

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
