Scientists discover the 'missing link' that triggers Alzheimer’s - and hope findings could lead to drugs that restore memory
Researchers have discovered a protein that they claim is the missing link to the development of Alzheimer’s disease.
They found that blocking this protein with an existing drug can restore memory in mice with brain damage that mimics the disease.
The findings could offer hope of developing drugs to slow the degenerative illness.
'What is very exciting is that of all the links in this molecular chain, this is the protein that may be most easily targeted by drugs,' said the study’s senior author Stephen Strittmatter at Yale School of Medicine. The study offers hope of developing drugs to slow the degenerative illness
'This gives us strong hope that we can find a drug that will work to lessen the burden of Alzheimer’s.'
Eat like the Greeks to stay sharp in old age: Mediterranean diet found to lower risk of developing dementia
Eating a Mediterranean diet is good for the mind, research has concluded. Scientists say people who eat large quantities of fresh fruits and vegetables, nuts, fish and olive oil have a lower risk of age-related diseases such as dementia.
The research, by the University of Exeter’s Medical School, is the first systematic review of previous studies into the diet’s benefits to the brain. It comes after research last month showed the same diet could help counteract a genetic risk of strokes. The team, supported by the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care in the South West Peninsula, analyzed 12 eligible pieces of research, 11 observational studies and one randomized control trial.
In nine of the 12 studies, a higher adherence to a Mediterranean diet was associated with better cognitive function, lower rates of cognitive decline and a reduced risk of Alzheimer’s disease.
How 'misleading' food labels are 'worsening the obesity crisis'
Fat-free yogurt may cause greater weight gain that the full-fat kind, according to researchers behind a new $40million dollar nutrition project. Gary Taubes and Dr Peter Attia of Nutrition Science Initiative, contend that the sugars and additives added to replace missing fats, drive insulin resistance - an underlying cause of obesity. They say this trend applies to all low-fat food options, from breakfast cereals to salad dressings, which many people 'wrongly' assume are healthier than the 'classic' versions.
Daily dose of testosterone wards off dementia in women
New research shows women who rubbed testosterone gel on their skin every day for six months performed better in brain function tests than those who were given a dummy gel. Researchers tested the treatment on a group of 96 healthy post-menopausal women. The hormone group performed significantly better at verbal learning, where they listened to dozens of different words and had to recall as many as they could. They also scored higher in tests designed to assess the efficiency of their short-term memory. Boosting brain function is thought to be one of the most effective ways of warding off dementia, as it helps strengthen connections between brain cells.

Thousands of 'well-dressed' women dying from strokes as doctors think they look healthy
Cardiologists said too many doctors are missing crucial signs of heart problems in women because many of those at risk were well-groomed and looked healthy. The study of more than 15,000 people found that female patients were half as likely as men to be treated for one of the leading causes of heart problems.

Researchers said that GPs and specialists were slow to diagnose the most common form of abnormal cardiac rhythm in women, increasing their risk of stroke and death. Dr Pierre Sabouret, lead researcher and cardiologist from Heart Institute-Pitie Salpetriere Hospital in Paris, said he believed many doctors did not realize how common the condition was among women, and failed to carry out tests to establish the likelihood of a problem. He said: "I think doctors - GPs and cardiologists - often do not realize the risk for women. Too often they will think if a female patient looks healthy, and dresses smartly, and looks after herself, she is probably okay."
