There may be a cure or, at least, a safe, inexpensive treatment for Alzheimer's disease: coconut oil.
Certainly, adding a little coconut oil to an Alzheimer sufferer's diet will do little to no harm. Coconut oil is readily available in most organic food stores.
Further study on the therapeutic benefits of coconut oil, and particular ketones, will need to be done by the public sector to confirm the findings. There's no profit in it for medical industry corporations so they cannot be expected to be part of this life saving, suffering alleviating potential.
