補充魚油可助降低老人癡呆症的風險
Fish oil supplementation may help to lower the risk of developing
dementia More
than 100,000 people with dementia are currently prescribed
antipsychotic drugs which have now been shown to cause significant
cognitive deterioration.
The Alzheimer's Society has commented on new research showing
that antipsychotic drugs accelerate cognitive deterioration
in people with Alzheimer's disease published in the Public
Library of Science medical journal.
This important research demonstrates that antipsychotic drugs
not only have no long-term benefit for people with dementia,
but also cause significant cognitive deterioration.
Over 100,000 people with dementia are currently prescribed
antipsychotic drugs. Previous research has shown that antipsychotic
drugs increase the risk of stroke and death for people with
dementia. This blanket prescription puts vulnerable people
at risk of side effects that are extremely distressing both
for sufferers and their families. This widespread over prescription
to people with dementia must stop.
Neil Hunt, chief executive of the Alzheimer's Society, says:
“Dementia isn't just forgetfulness; it's caused by diseases
of the brain and more than half of all people with dementia
experience behavioural symptoms as part of their condition.
Alzheimer's Society research has shown that basic dementia
training can help staff deal with these symptoms and reduce
the use of antipsychotic drugs by 50%. It is time we stop
wasting money giving people drug treatments with no benefit
and start investing in good quality dementia care.”
“A report from the first parliamentary inquiry into the overuse
of these drugs is due to be published next month. It is vital
the government acts now to address this serious issue. Antipsychotics
should only be given to a person with dementia as a last resort
in the short term, when all other treatment options fail.”
A study by the Alzheimer's Society published in the British
Medical Journal on 16 March 2006 found that training and educating
care home staff about dementia reduces disruptive behaviour
and the use of antipsychotics by 50%.
Another study has found that diet is of critical importance
and that eating fish or seafood at least once a week lowers
the risk of developing dementia. A team of French researchers
asked elderly people about their eating habits and found a
link between eating fish, which has high levels of polyunsaturated
fatty acids, and a reduced risk of dementia, including Alzheimer's
disease.
Over 1,670 people aged 68 or over living in south-west France
took part in the survey, the results of which were published
in 2002. They were all taking part in a long-term study of
how age affects mental function and behaviour. They were classed
as eating meat or fish every day, at least once a week (but
not every day), from time to time (but not every week), or
never. Researchers went back to talk to the study participants
two, five, and seven years later. They were asked how often
they ate fish (high in omega-3) or meat (rich in saturated
fatty acids). It was found those who ate fish or seafood at
least once a week had a significantly lower risk of developing
dementia over the seven years of the study.
Fatty acids in fish oils have a protective effect on the
vascular system, and the researchers say they could also reduce
inflammation in the brain and have a specific role in brain
development and regeneration of nerve cells.
The protective effect of omega-3 appeared to be less strong
for more highly educated people, suggesting that this could
be explained by healthy eating habits when young which could
be linked with higher educational achievements, or because
they follow recommendations on how much fish to eat more closely.
No significant link was seen between eating meat and a risk
of dementia. Pascale Barberger-Gateau of the University Victor
Segalen in Bordeaux who led the study, said: "Elderly
people who eat fish or seafood at least once a week are at
a lower risk of developing dementia, including Alzheimer's
disease."
The fact of the matter is that most people do not consume
enough oily fish to reap the benefits of fatty acids, so supplementation
with fish oils is a more viable option for many.
Fatty acids play an important part in the functioning of
every living cell in the body. Specifically they may help
the body in several ways including: improving the circulatory
system, aiding concentration, maintaining a well-balanced
state of mind and keeping joints in good condition.
Omega product is a patented and highly concentrated formulation
of ultra-pure EPA (eicosapentaenoic acid) from marine fish
oil and GLA (gamma-linolenic acid) from organic virgin evening
primrose oil, providing a highly concentrated source of omega-3
& -6 long chain fatty acids and botanical triterpenes.
This unique combination of natural fatty acids provides cell
membranes with the nutrients required for efficient chemical
signalling integral to healthy brain function. Just two capsules
daily can help to reverse a fatty acid deficiency by increasing
the amount of phospholipids in brain-cell membranes. As a
result, messaging between neurons is enhanced and cognition
improves. An increasing number of doctors and nutrition experts
are using omega product to treat the symptoms of dementia including
Alzheimer's and Huntington's disease. |
