Dr. Steve Blake designed and helped implement the Hawaii Dementia Prevention Trial, a clinical study at the Hawaii Alzheimer's Disease Center. His study found that changes in nutrition could affect the progression of Alzheimer's disease. Parkinson's disease is also powerfully affected by diet. Reducing protein to just the needed amount can allow much better production of dopamine with the potential to cut symptoms in half. With migraines, avoiding dietary triggers can help reduce the frequency and severity of migraine headaches. He emphasizes that we can no longer ignore the role of diet in neurologic disorders. He discusses how nutrition can reverse atherosclerosis and hypertension. He found this was a successful approach in improving cognitive functioning in persons with mild cognitive impairment, in preventing strokes, and in reversing atherosclerosis and hypertension.
