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.
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.
Lower birth weight in medically assisted reproduction babies does not appear to hamper cognitive development to the same degree that it does in naturally conceived children with lower weight at birth.
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.

Using AI technology to analyze CMR scans, researchers were able to precisely quantify the blood flow to the heart muscles of patients. Comparing the AI-generated blood flow results with health outcomes, the team found those with reduced blood flow were at increased risk of stroke, heart attacks, and heart failure. The machine-learning algorithm was able to predict which patients may die or suffer major adverse health events better than doctors could.
Researchers have identified a layer of genetic material involved in controlling the production of tau in the brain. The material is part of a larger family of non-coding genes that regulate and control other brain proteins associated with neurodegenerative disorders, such as Alzheimer's disease, Parkinson's, and PSP. The findings could lead to the development of new therapeutics to treat a range of neurodegenerative disorders.
Glioblastoma can mimic the normal repair of white matter in the brain, causing the tumor to become less malignant. Additionally, a drug commonly prescribed for asthma can help suppress glioblastoma growth in mouse models.
A new case study reveals a link between COVID-19 and clotting in blood vessels in the brain that results in an increased risk of ischemic stroke. Five of the six cases included in the study suffered an ischemic stroke within 8-24 days of the onset of coronavirus symptoms. Early use of anticoagulants might help reduce the risk of blood clotting and stroke in patients with COVID-19.
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.
