Dementia: Lack of vitamin D could have ‘causal effect’ on dementia warns study

Most of the body’s organs clear out waste with the help of the lymphatic system, but the brain uses a different plumbing system.

Cerebrospinal fluid relies on the pulsing of the arteries to actively wash through the brain, collecting junk – a mechanism known as the glymphatic system.

When this system falters, superfluous proteins collect between the organ’s neurons, thwarting communication between cells.

Vitamin D, thanks to its neuroprotective qualities, is believed to shield brain cells against such damage.
