High activity in the brain regions that Alzheimer's affects first boosts amyloid beta levels, new findings have indicated.
Research from the Washington University School of Medicine in St Louis explained that the regions first affected by the plaques are those which are more active when the brain is resting.
The study, published in journal Nature Neuroscience, revealed that busier brain cells both contribute to and prevent Alzheimer's.
David M. Holtzman said that engaging the brain in activities such as socialising, reading or studying could be helpful as they lessen the activity in these brain regions.
"I suspect that sleep deprivation and increased stress, which may affect Alzheimer's risk, may also increase activity levels in these vulnerable regions," he continued.
In other news, research published in the Journal of Alzheimer's Disease has revealed that a tobacco compound could prevent the memory loss experienced by people with the condition.
Cotinine, which is derived from tobacco, triggered a decline in the plaques linked to dementia when tested in mice.
