Ecstasy

People using Ecstasy for as little as one night are putting themselves at risk of developing Parkinson's disease, warns a new investigation of the drug's effects on animal brains.

The study uncovers evidence of a type of nerve damage never previously seen in monkeys or rats exposed to Ecstasy, or MDMA, and will stoke an increasingly acrimonious debate about whether it is toxic to human nerve cells.

George Ricaurte and his team at Johns Hopkins University in Baltimore, Maryland, gave up to three consecutive doses of the drug to squirrel monkeys and baboons. The doses were administered two hours apart in a bid to mimic the way some all-night clubbers use the drug.

Weeks later, the researchers examined the animals' brains and found evidence of what they call "profound and severe" damage to dopamine-producing neurons. These are the nerve cells lost in Parkinson's disease and their healthy function is important for movement, speech and cognition.

The animals' brains had abnormally low levels of both dopamine and certain "transporter" proteins that handle this neurotransmitter. The researchers also detected signs of inflammatory damage.

"The damaging effect of MDMA, together with the decline in dopaminergic function known to occur with age, may put individuals at increased risk of developing Parkinsonism and other neuropsychiatric diseases either as young adults or later in life," the researchers write in the journal Science.

The paper also admits some people already diagnosed with early-onset Parkinson's disease may unknowingly be victims of MDMA.
dit is t zelfde onderzoek als die in de topic die isios heeft geopend denk ik mizz mako of niet?
