Transformative Approaches to Addressing Hidden Risks in Nearly Half of Dementia Cases

Buzzline

A comprehensive four-year investigation from Lund University reveals that close to fifty percent of dementia occurrences may be linked to alterable risk factors. The study monitored nearly 500 individuals averaging 65 years of age, all without cognitive impairment, examining the relationship between changes in white matter and the presence of amyloid beta and tau proteins. Key modifiable risk factors identified include smoking, cardiovascular conditions, elevated blood lipids, and hypertension, all associated with vascular damage and accelerated white matter deterioration. The researchers emphasize that prioritizing vascular and metabolic risk factors could mitigate the cumulative effects of various simultaneous brain changes.

00:00Nearly half of dementia cases may be connected to risk factors that people can potentially change,

00:06including smoking and high blood pressure.

00:08That comes from new research at Lund University.

00:12Dementia is not a single disease.

00:14It is a collection of symptoms that can result from several different disorders.

00:18So researchers examined the two most common causes.

00:22Alzheimer's disease and vascular dementia.

00:25The study involved almost 500 participants with an average age of 65.

00:30None of whom showed signs of cognitive impairment.

00:33Researchers followed them for four years.

00:35They measured changes in the brain's white matter.

00:38The nerve fibers that are often damaged in vascular dementia.

00:42They also monitored amyloid beta and tau, two proteins associated with Alzheimer's disease.

00:48Most modifiable risk factors, including smoking, cardiovascular disease, high blood lipids, and high blood pressure,

00:56were linked to damage to the brain's blood vessels and a faster accumulation of white matter changes.

01:03Diabetes was associated with increased accumulation of amyloid beta.

01:07People with lower body mass index had faster accumulation of tau.

01:11Researchers say those two findings need to be investigated further and validated in future studies.

01:17Their conclusion, focusing on vascular and metabolic risk factors,

01:21can still help reduce the combined effects of several brain changes happening at the same time.
