After five years, 298 people developed Alzheimer’s disease. The other still had mild cognitive impairment. People with risk factors such as hypertension, diabetes, cerebrovascular disease and high cholesterol are twice as likely to develop Alzheimer’s than those without vascular risk factors. A total of 52 percent of those risk factors developed Alzheimer’s disease, compared with 36 percent of those with no risk factor.Among people with vascular risk factors, people who have received a complete treatment were 39 percent less likely to develop Alzheimer’s than those who do not receive treatment. Those who received no treatment were 26 percent less likely to develop the disease than those who received no treatment.
Treatment of high blood pressure, high cholesterol, diabetes and other vascular risk factors may help reduce the risk of Alzheimer’s disease in people who already show signs of decline in thinking skills or memory problems. The research is published in the April 13, 2011, online edition of Neurology, the medical journal of the American Academy of Neurology.
“Even if it was not a controlled study, patients who were treated for hypertension, high cholesterol, heart disease and diabetes are less progression of their memory or thinking impairment and were less likely to develop dementia,” said the ‘study author Jiang-Yan Wang, MD, Ph.D., the Third Military Medical University in Chongqing, China.
