Key Highlights
•
A study found that traumatic brain injury (TBI) is a significant risk factor for developing dementia before the age of 65, known as early-onset dementia. The risk was even higher for people who had more severe TBIs, highlighting the long-term neurological consequences of head injuries.

Researchers discovered that epigenetic clocks, which measure biological aging from DNA, did not reliably predict a person’s risk of developing Parkinson’s disease, their age at onset, or how quickly symptoms appeared. This suggests these specific biomarkers may not be useful for forecasting Parkinson’s disease in clinical practice.

Scientists engineered CAR T cells, a type of cancer immunotherapy, to produce more of a glucose transporter protein (GLUT3) on demand, which boosted their energy and ability to fight tumors in models of glioblastoma. This metabolic enhancement could lead to more potent therapies for hard-to-treat brain cancers.
