"Middle-aged people who drank between three and five cups of coffee a day lowered their risk of developing dementia and Alzheimer's disease by between 60 percent and 65 percent later in life," said lead researcher on the project, Miia Kivipelto, a professor at the University of Kuopio in Finland and at the Karolinska Institute in Stockholm.
The study, which was also conducted in cooperation with the National Public Health Institute in Helsinki and which was published... read more
Washington: Men who develop diabetes in middle age are at significantly increased risk of developing Alzheimer's disease later in life, according to a long-term study published recently.The study involved 2,269 men in Sweden who underwent testing at age 50 for diabetes, a disease caused by abnormal insulin levels.During a follow-up period averaging 32 years, 102 of the participants were diagnosed with Alzheimer's, 57 with vascular dementia, and 235 with other forms of dementia or cognitive impairment.The authors, writing in the medical journal Neurology, concluded that the men with low insulin levels at age 50 were nearly 1.5 times more likely... read more
Paris: Scientists recently reported that they had developed an experimental drug to combat Alzheimer's that employs a double-pronged attack against a rogue protein fingered for causing the disease.
The drug-still in clinical trials-is part of a class called gamma-secretase modulators (GSMs), but until now, very little was known as to why the molecule appears to work.
GSMs' target is the accumulation of amyloid beta protein, which forms plaques in the brain and eventually leads to the tragic mind-wrecking disease, symptomized by forgetfulness and dementia.
In a study published in the British journal Nature, a team of 29 US and European researchers found that... read more
