News items on 'Alzheimer's Disease'
Dementia patient care criticised
(BBC 17/11/2009)
Hospital stays for people with dementia are far longer than for patients being treated for the same injury or illness but without dementia, it is claimed. The Alzheimer's Society says patients with dementia occupy a quarter of hospital beds and the majority leave in a worse state than when they arrive. It wants their stays cut by a week, saying it will save millions of pounds. The government said it had already asked NHS hospitals to take urgent action on this issue.
Link found between Alzheimer'sand heart disease
(The Scotsman 16/11/2009)
LINK has been found between Alzheimer's disease and chronic heart failure. Scientists believe both conditions involve a build-up of harmful protein in the body. In heart disease, researchers have found that clusters of proteins called desmin amyloid are formed. They are similar in structure to the plaques in the brain believed to play a key role in Alzheimer's. Desmin is a protein that normally forms structural filaments in heart muscle cells. Researchers made the discovery in dogs.
Alzheimer's risk 'linked to weaker muscles'
(The Scotsman 10/11/2009)
WEAK muscles are closely linked to Alzheimer's disease in older adults, a study suggests. The research, from the United States, showed a pattern of reduced Alzheimer's risk with increasing muscle strength. The strongest patients had 61 per cent less chance of developing the disease than the weakest. No reason for the association has yet been found, but it could involve energy production in the body or other hidden health problems, the scientists believe.
Multi-tasking test spots onset of Alzheimer's
(The Scotsman 09/11/2009)
A test for Alzeimer's? A team led by Professor Sergio Della Sala compared the "dual-tasking" ability of 89 Alzheimer's patients, sufferers of chronic depression and healthy elderly individuals with no memory impairment. The findings, reported in the Journal of Neurology, showed that people with Alzheimer's performed significantly worse than the other two groups. This was true even when allowances were made for individual memory differences.
Protein-rich diet link to Alzheimer's in test mice
(The Scotsman 21/10/2009)
SCIENTISTS studying Alzheimer's disease in mice have found a high-protein diet led them to develop smaller brains. Their findings could reverse previous dietary advice on how to avoid Alzheimer's. Researchers from the US, Canada and the UK were focusing on triggers for brain plaque formation and monitored the effects of four food regimes on rodents genetically modified to develop severe, early onset Alzheimer's.

Memory not first Alzheimer's sign
(BBC 13/10/2009)
A failing memory may not be the first mental problem to signal the onset of Alzheimer's disease, research suggests. A University of Kansas study found a decline in other thinking and learning skills may be a warning sign years before diagnosis. The spatial skills, such as reading a map or completing a jigsaw, seem to be the first to falter. The Archives of Neurology study may help doctors to identify Alzheimer's at an earlier stage.

Poor sleep linked to onset of Alzheimer's disease
(The Scotsman 25/09/2009)
CHRONIC lack of sleep may promote the development of Alzheimer's disease, new research suggests. The findings have implications for people suffering from insomnia and other sleep disorders, say scientists. Researchers monitored levels of amyloid beta, a protein fragment known to be linked to Alzheimer's, in the brains of sleep-deprived mice with symptoms of the disease. They found that preventing the mice from sleeping caused a 25 per cent increase in amyloid beta levels [early research].
Money problems 'signal dementia'
(BBC 22/09/2009)
Declining financial skills are detectable in patients in the year before they develop Alzheimer's, according to US researchers. The researchers say this could be a useful indicator for doctors supporting people with memory problems. Previous studies have shown that problems with daily activities often precede the onset of Alzheimer's. But charities said most people having trouble working out figures should not be alarmed by the study.

Study suggests infections can worsen Alzheimer's
(The Scotsman 08/09/2009)
ALZHEIMER'S sufferers who catch a cold or a stomach bug need to be treated as soon as possible to prevent it worsening their dementia, new research has suggested. A study by scientists at the University of Southampton found a link between the infections and an increase in inflammation-like reactions in the brain, which led to an increased rate of cognitive decline. The research showed that people who got an infection had twice the rate of cognitive decline as people without infections.
