COUGHS & SNEEZES SPREAD BRAIN DISEASES
Nov 4 2004
Experts claim colds cause mental illness
By Judith Duffy
COUGHS and sneezes can cause more than a cold - they can spread mental illness, scientists warn.
People can catch mind disorders such as schizophrenia or depression simply by being exposed to bugs that attack the brain.
So many potential 'mind germs' have now been unearthed that some researchers are ready to challenge the conventional wisdom about the principal causes of mental illness, reports New Scientist.
Epidemiologists discovered a prenatal infection could be linked to the development of schizophrenia years later.
A blood test study of women in California who were pregnant between 1959 and 1966 found maternal exposure to flu during the first half of pregnancy tripled the child's risk of developing a schizophrenia disorder.
Dr Alan Brown, of Columbia University, said: 'It's far higher than any single gene in terms of what we call relative risk.'
Schizophrenia is rare, affecting only one per cent of the population.
But Dr Brown believes if the results can be duplicated, up to 14 per cent of cases could be preventable.
Several other bugs have come to light that are able to trigger symptoms of mental illness - ranging from behavioural problems to depression and full-blown psychosis.
When it comes to causes of mental illness, genes have always been the prime suspects, with environmental factors playing a lesser role.
Infectious disease is almost an afterthought.
But evolutionary biologist Paul Ewald, of Kentucky, says that ignores some obvious facts.
He said: 'The biggest breakthrough in the history of psychiatry was recognising that syphilis causes insanity and that it can be prevented with antibiotics.'
Dr Ewald believes the same mistake is being repeated today with Lyme disease and other infectious agents.
Lyme disease, a tick-borne illness identified in the late 1970s, is caused by bacteria that are able to burrow into tissue and stir up brain disorders, research shows.
If diagnosed quickly, it can now be cured with a simple round of antibiotics.
The idea that you can catch a mental illness from a bug bite or a sneeze may seem the stuff of nightmares.
But it also holds hope that treatment could, one day be as simple as tackling an infection.

Lisää tietoa Ewaldista ja hänen teoriastaan -mielenkiintoinen juttu! Hänen mukaansa esim. syöpä ja sydänsairaudet, joiden on ajateltu johtuvan esim. geneettisistä syistä, ympäristötekijöistä tai elämäntavoista, ovat mikrobien aiheuttamia sairauksia.

Paul W. Ewald, Ph.D., is a professor of biology at The University of Kentucky. Ewald, the author of the groundbreaking book Evolution of Infectious Disease and a follow-up, Plague Time, is widely credited as the father of a new discipline called evolutionary medicine. He has demonstrated that a great range of medical ailments cannot be well understood -- and in many cases have been tragically misunderstood -- without a Darwinian evolutionary perspective.
For example, he has shown that there is a direct relationship between how easy it is for a bacterium, virus or parasite to spread among its victims and how virulent it can afford to be. This new understanding has opened serious new avenues for designing treatment programs and improving public health around the globe. By influencing, for instance, how a particular disease gets spread through the human population, we can encourage it to evolve into a more benign form.
Ewald also argues that there are a lot more deadly pathogens at work against us than just the blatantly obvious infectious diseases people have known about for a long time, like chicken pox, the plague, syphilis and the flu. Ewald has shown, to the surprise of the medical community, that many common afflictions such as heart disease and cancer -- diseases which doctors have long thought were rooted purely in genetics, environment or lifestyle -- are in fact caused by infections.
