Cognitive health benefits linked to education and financial stability

Socioeconomic factors such as education, occupation, and wealth influence the likelihood of developing cognitive impairment or dementia in later life and whether a person is likely to recover, finds a new study led by UCL researchers.

Researchers achieve accurate EV analysis to detect brain disease

Brain disorders like Parkinson's (PD) or Alzheimer's Disease (AD) start to develop in patients much earlier than when their first clinical symptoms appear. Treating patients at these early stages could slow or even stop their disease, but there is currently no way to diagnose brain disorders at those pre-symptomatic stages.
