Speaking of Parkinson's

Brain damage 'crisis' looms from illicit drug use - ABC News (Australian Broadcasting Corporation)

Researchers in Adelaide are investigating links between stimulant use and an increased risk of people developing Parkinson's disease.

They said many drug users were developing a brain abnormality which also was seen in people afflicted with Parkinson's.

"People who have used illegal stimulants in the past have a change in a brain region that's right in the middle of their brain called the susbtantia nigra," explained Dr Gabrielle Todd, a senior researcher at the University of South Australia.

A recent German study found otherwise-healthy people with that abnormality were 17 times more likely than others to develop Parkinson's.

"When we looked at the brain stems of fairly young people, all less than 45 years old, they had the same changes that we saw in people with Parkinson's disease," Flinders Medical Centre neurologist Dr Rob Wilcox said.

The Parkinsons-amphetamine link is physiologically obvious and has been known for a long time now. There is a rising trend in neurologic disorders but the causes of that remain unclear. Very worrying. See:
