.....first .......let me say this............................................................. :badair:



(Reuters Health) - Women who are infected with a common parasite may be more likely to hurt themselves or attempt suicide, a new study of over 45,000 new moms in Denmark suggests.

The infection, known as toxoplasmosis, is caused by the parasite Toxoplasma gondii. Humans can become chronically infected by eating undercooked meat or unwashed vegetables or by handling cat litter, as the parasite is known to multiply in the gut of infected cats.

Toxoplasmosis is often symptom-free, but can be dangerous in people with weak immune systems or during pregnancy, since the parasite may be passed to babies.

Some studies have linked the parasite to a higher chance of developing schizophrenia, and researchers believe because the T. gondii parasite lives in the brain, it could have an effect on emotions and behavior.

For the new report, Dr. Teodor Postolache from the University of Maryland School of Medicine in Baltimore and his colleagues used Danish medical registries to track 45,788 women who were originally included in a study that screened newborn babies for toxoplasmosis.

All of the infants were tested for antibodies against the parasite through a blood sample drawn five to 10 days after birth. Because the babies were still too young to make their own antibodies, any that showed up in their blood would have been passed from moms.

Just over one-quarter of the babies were positive for T. gondii antibodies, meaning their mothers likely had a chronic, underlying toxoplasmosis infection.

And over the next 11 to 14 years, infected women were about 50 percent more likely to cut, burn or otherwise hurt themselves, according to their medical records, and 80 percent more likely to attempt suicide.

In total, 488 women hurt themselves for the first time during the study - or eight out of every 10,000 annually - and 78 tried to kill themselves.

They reccon it 'reprograms' brains to aid 'self' in transmission (ie. mice/rats/rodents loose their fear of cats...... or dogs start eat cat poo..... That sorta thing).

So there's a deeper thing here2. Is freewill free?

Under normal circumstances, a rat steers clear of cats and their odours. But rats infected with the parasite Toxoplasma gondii develop a deadly attraction to the feline scent. This abnormal behaviour often leads them to the mouth of their predator, and allows the parasite to enter and complete its reproductive cycle in the cat.

It was no surprise, then, that in Webster's recent experiment untreated infected rats chose to spend nearly three times as much time in laboratory containers holding woodchips treated with feline urine than their control counterparts. And the rats given anti-T. gondii drugs spent about 30% less time in the feline-scented area than the untreated infected rats.

But infected rodents given only haloperidol as a treatment similarly spent 28% less time around cat scent than their untreated but infected counterparts. All of the rats had been infected with the parasite in adulthood.

Webster suspects that the antipsychotic drug somehow suppresses replication of the parasite, stemming the development of the fatal feline attraction. She admits that the rodents' abnormal behaviour is an imperfect model for human schizophrenia, but adds the observed changes in the rodents following haloperidol provides useful insights into the neurobiology of cognitive disorders.

She adds that more research is necessary to explore the possible link between toxoplasmosis and schizophrenia. And she stresses that the infection is common - affecting an estimated 50% of the UK population - so it could not trigger psychosis in all people carrying the parasite: "We don't want to be scare-mongering."

K. I see's it likes this. If a bug (virus/bateria/wot ever) can makes you phyically ill (or even kill ya), Why not mentally as well. It's just not a big jump 4 me.
