A recent report on a study by a Southampton University team has appeared in the journal Public Health.
It finds that dementia rates have trebled in men and increased by 90 per cent among women.
The
study examined rates of the diseases in much of the Western world from 1979 to 1997. "This has really scared me," Professor Colin Pritchard, who led the study. "These are nasty diseases: people are getting more of them and they are starting earlier. We have to look at the environment and ask ourselves what we are doing."
"There's no single cause ... and most of the time we have no studies on all the multiple interactions of the combinations on the
environment."
The report covered the incidence of brain diseases in Britain, the US, Japan, Australia, Canada, France, Germany, Italy, the Netherlands and Spain from 1979-97. It found that dementias - mainly Alzheimer's, but including other forms of senility - more than trebled for men and rose nearly 90 per cent among women in England and Wales. All the other countries were also affected.
The team stresses its figures allow for increased longevity and improved diagnoses of such ailments. It is comparing death rates, not numbers of cases, it says.
Food is also a concern because it provides the most obvious explanation for the exclusion of Japan from many of these trends. Only when Japanese move to the other nations do their disease rates rise.
A rather disturbing trend, and one that is worth keeping an eye on. I can't help but wonder if it may be related to a
story reported earlier?
