Walking 5,000 steps daily can slow cognitive decline and the build-up of proteins linked to Alzheimer’s.
Scientists at Harvard University have analysed data from individuals aged 50-90), with amyloid and tau proteins in their systems who had not yet displayed symptoms of dementia.
For 14 years, they wore pedometers to track their steps.
The study reveals a clear link: higher levels of physical activity are associated with a slower deterioration in thinking and memory skills.
A modest 3,001-5,000 steps per day is linked to a notable slowing of tau accumulation and cognitive decline, but 5,000-7,500 steps daily is even better.
Consultant neurologist Dr. Steven Allder says that walking increases blood flow and oxygen delivery to the brain, which is essential for maintaining optimal neurological function.
The journal Nature Medicine has details.
