Coffee reduces Alzheimer's risk: study

Middle-aged people who drink moderate amounts of coffee significantly
reduce their risk of developing Alzheimer's disease, a study by
Finnish and Swedish researchers showed Thursday.
"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 and 65 per cent 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 in the
Journal of Alzheimer's Disease this month, was based on repeated
interviews with 1,409 people in Finland over more than two decades.
They were first asked about their coffee-drinking habits when they
were in their 50s and their memory functions were tested again in
1998, when they were between 65 and 79 years of age.
A total of 61 people had by then developed dementia, 48 of whom had
Alzheimer's, the researchers said.
"There are perhaps one or two other studies that have shown that
coffee can improve some memory functions (but) this is the first study
directed at dementia and Alzheimer's (and) in which the subjects are
followed for such a long time," Kivipelto told AFP.
She said it remained unclear exactly how moderate coffee drinking
helped delay or avoid the onset of dementia, but pointed out that
coffee contains strong antioxidants, which are known to counter
Alzheimer's.
Some studies have also shown that coffee helps protects the nerve
system, which can also protect against dementia, she said, pointing
out that yet other studies show that coffee protects against diabetes,
which in turn is known to be linked to Alzheimer's.
"Going forward, researchers should try to nail down exactly what the
protective elements in coffee consist in," Kivipelto said.
The Finnish-Swedish research results surfaced just a day after a
separate study published by psychologists at Durham University showed
a link between heavy coffee drinking and hallucinations.
"I guess this shows that you shouldn't exaggerate," Kivipelto said
when asked about the British study, pointing out that her research
showed "insignificant" benefits to drinking more than five cups of
coffee a day when it came to protecting against dementia.
"Too much is simply too much," she said.
