Being socially active in early old age can help to prevent against dementia later on. Researchers found those engaged in social activities almost daily at 60 were 12% less likely to develop dementia than those who were socially active only once or twice a month.
Canned laughter tracks increase how funny we find a joke and how much we laugh, even when the jokes are groan-worthy. Testing the hypothesis on both neurotypical people and those on the autism spectrum, researchers found the effect was universal.
Capillary constriction caused by amyloid beta restricts cerebral blood flow in mouse models of Alzheimer's disease. Inhibiting the capillary constriction may potentially reduce some of the neurodegenerative features of Alzheimer's.

Combining artificial intelligence technology with MRI brain scans, researchers are able to detect the brain's response to Natalizumab treatment for those with relapsing-remitting multiple sclerosis.
Sleep duration can have a negative impact on memory skills and reaction time. While the effects of sleep deprivation are well documented, researchers report sleeping for longer than the recommended 7 to 8 hours per night is associated with more errors in memory recall and slower reaction times, with each additional hour of sleep impacting performance more.
A variant of the CHC22 gene evolved to help people adapt to the modern, higher sugar diet. However, many people still retain the older version of the genetic variant, which does not allow for correct metabolism of modern diets and may be linked to an increased risk of developing diabetes.
Women who suffered from eating disorders are at increased risk of developing depression during pregnancy and up until 18 years after the birth of their child.
The common statin drug Simvastatin reduces brain atrophy and slows the progression of secondary progressive multiple sclerosis (SPMS). The effects appear to be independent of the drug's cholesterol-lowering effects.
People with the specific genotype of the Cannabinoid receptor 1 gene may be more prone to cannabis use disorder. Researchers report those with FAAH rs324420 A continue to want more marijuana following use and are more drawn to cannabis-related imagery while under the influence of the drug.
The posterior hippocampus tracks distance to a newly learned location, as well as familiar environments. By contrast, when navigating a familiar location, the retrosplenial cortex takes over responsibility for tracking distance. The findings shed light on how the brain navigates and encodes spatial information.
