PhotoCredit:istock Administering the primary female sex hormone oestrogen via a skin patch shortly after menopause may reduce Alzheimer’s risk in women, suggests new research. The study, published in the Journal of Alzheimer’s Disease, found that newly postmenopausal women who received oestrogen via a skin patch had reduced beta-amyloid deposits, the sticky plaques found in the brains of people with Alzheimer’s disease. “This study showed, for the first time, that the brain amyloid deposition — a hallmark of Alzheimer’s disease — is reduced in newly postmenopausal women who received 17beta-Estradiol patch…

Decreased Blood Flow in Brain Earliest Sign of Alzheimer’s

PhotoCredit:istock Contrary to previous understanding, the first physiological sign of Alzheimer’s disease is a decrease in blood flow in the brain, say researchers. An increase in amyloid protein was considered to be the first detectable sign of Alzheimer’s. While amyloid certainly plays a role, this study found that changes in blood flow were the earliest known warning sign of Alzheimer’s. Led by Alan Evans from Montreal Neurological Institute and Hospital, the researchers analysed more than 7,700 brain images from 1,171 people in various stages of Alzheimer’s progression using a variety…

Eyes Help Researchers ‘See’ Alzheimer’s Before Symptoms

PhotoCredit:istock Scientists, including one of Indian-origin, have discovered that eyes could help them see progression of Alzheimer’s disease even before the onset of symptoms. The research may help overcome a major roadblock in the development of therapies for the brain disorder characterised by memory impairment. Looking through the eye to see the brain is a key advantage of the new technology. “The retina of the eye is not just ‘connected’ to the brain — it is part of the central nervous system,” said author Swati More of the University of…

Scientists have identified the first physiological sign of Alzheimer’s disease -a decrease in blood flow in the brain -using a powerful tool to better understand the progression of the debilitating disease. Led by Alan Evans, a professor at Montreal Neurological Institute (MNI) in Canada, the researchers analysed over 7,700 brain images from 1,171 people in various stages of Alzheimer’s progression, using a variety of techniques including magnetic resonance imaging (MRI) and positron emission tomography (PET). Blood and cerebrospinal fluid were also analysed, as as well as the subjects’ level of…
