Dementia: Vitamin D deficiency could have a ‘causal effect’ on dementia, study warns

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

Cerebrospinal fluid relies on the pulsation of the arteries to actively flush the brain, collecting debris – a mechanism known as the glymphatic system.

When this system is shaken, excess proteins collect between the neurons of the organ, disrupting communication between cells.

Vitamin D is thought to protect brain cells from such damage due to its neuroprotective properties.
