High homocysteine tied to Alzheimer’s

For the first time, research has linked the incidence of Alzheimer’s disease and other forms of dementia to elevated blood concentrations of the amino acid homocysteine.

Scientists had previously connected high homocysteine concentrations to heart disease and stroke, maladies associated a heightened risk of Alzheimer’s disease and other dementias. Also, a few scientists had already noted high homocysteine concentrations in the blood of Alzheimer’s patients.
