In 1980s, 65% of all East Boston residents over the age of 65 were recruited in the study of neuroprotective effects of vitamins C and E. None of the people taking vitamin C or vitamin E developed Alzheimer’s disease when followed up in 4.5 years while among vitamin C non-users, 85% developed the disease. Among vitamin E non-users, 14% developed Alzheimer’s (1)
I was shown that supplementation with vitamin E and/or vitamin C might be useful in maintaining brain acetylcholinesterase (footnote a) activity at the normal level and serotonin (footnote b) concentration for some extent under the condition to induce experimental dementia in experimental animals (2)
High intake of vitamin E from food (tocopherol), but not from supplements (which usually contain alpha-tocopherol), is shown to reduce incidence of Alzheimer’s disease. The most common alpha-tocopherol alone may not be sufficient in the protective effects (3)

a) Acetylcholinesterase (AChE) is an enzyme that degrades the neurotransmitter acetylcholine at neuromuscular junctions and cholinergic synaptic transmission in the brain.
b) Serotonin is a neurotransmitter found in the central nervous system. It is best known as a “happiness hormone” though it’s no hormone but monoamine.
