Scientists want to know more about the brain changes that lead to Alzheimer's
Controlling the level of a fatty acid in the brain could help treat Alzheimer's disease, an American study has suggested.
Tests on mice showed that reducing excess levels of the acid lessened animals' memory problems and behavioural changes.
Writing in Nature Neuroscience, the team said fatty acid levels could be controlled through diet or drugs.
An unhealthy lifestyle increases a person's risk of Alzheimer's disease
Rising rates of obesity will lead to dramatic increases in the number of people with Alzheimer's disease, experts have predicted.
In 50 years time, up to 2.5m people in the UK could have dementia unless steps are taken to stem the obesity epidemic, the Alzheimer's Society warned.
People are often advised to try to keep up their levels of so-called good cholesterol to reduce their risk of heart disease. But high levels may also help prevent a decline in memory, a new study says.
Now, researchers have caused Alzheimer's symptoms in rats by injecting them with one particular form of beta-amyloid. Injections with other forms of beta-amyloid did not cause illness, which may explain why some people have beta-amyloid plaque in their brains but do not show disease symptoms.
At 32, he's not worried about losing his memory. He's taking advantage of a growing market in "brain fitness" spurred by aging baby boomers.
Teenagers cramming for tests and people worried about "senior moments" can now turn to an explosion of brain-assisting video games, such as Nintendo's Brain Age; puzzles that are said to ward off dementia, such as Sudoku and crosswords; and online tips that claim to train the brain.
Giving elderly people either Aleve or Celebrex, two anti-inflammatory painkilling drugs, did nothing to ward off the mental decline associated with the onset of Alzheimer's disease, researchers said on Monday.
Finding could mean changing animal models used for future research

WEDNESDAY, April 23 (HealthDay News) -- An enzyme shown to help suppress development of Alzheimer's disease appears to hasten progress of a related but far less common type of dementia, according to a new study.
Heavy drinkers and smokers develop Alzheimer's disease six to seven years earlier than those who do not smoke or drink, US researchers claim.
Several teams are working on such a test but Power3 Medical Products says its could be launched in Europe this summer, Chemistry and Industry reports.
The drink has already been linked to a lower risk of Alzheimer's Disease, and a study by a US team for the Journal of Neuroinflammation may explain why.
Neuroleptics provided no benefit for patients with mild behavioural problems, but were associated with a marked deterioration in verbal skills.
That abdominal fat, sometimes described as making people apple-shaped rather than pear-shaped, has already been linked to higher risk of developing diabetes, stroke and heart disease.
A study found women's memories are affected when their bodies stop producing the hormone oestrogen - as happens at the menopause.
CBS News Interactive: About Alzheimer's
NEW YORK (CBS) ? New numbers illustrate the mounting toll of Alzheimer's disease.
In its second annual statistical report, the Alzheimer's Association projects that 10 million baby boomers will suffer from the disease.
The new method works by teaching a standard computer the differences between brain scans from patients with proven Alzheimer's, and people with no signs of the disease.
