Dementia is caused by damage to the vascular infrastructure in the brain
that has gradually built up there over many years. Vascular dementia occurs
when the blood supply to part of the brain is cut off and a lack of oxygen
causes the destruction of neurons. Also, the pumping mechanism for circulating
cerebrospinal fluid (CSF) throughout the brain to cleanse it of toxins
piggybacks on the pulsating expansion and contraction of healthy elastic
arteries.
When damaged arteries harden and lose elasticity, the pumping and
circulation of CSF becomes compromised and no longer properly cleanses the
brain of toxins which then destroy neurons to cause onset of Alzheimer’s
disease. Neither type of dementia can be cured because it is impossible to
repair the vascular damage.
