SUNDAY, Feb. 20 (HealthDay News) -- Taking prescription amphetamines may improve your venture of nonindustrial Parkinson's disease later, new investigate suggests.

But, the researchers noted that the think did not prove a cause-and-effect relation and boost enquiry is warranted.

Study author author K. Van Den Eeden, a senior policeman at the Division of Research at Emperor Permanente Northern California, in Oakland, said that people who reportable using upper or upper at whatever point in their lives showed a 60 percent greater quantity of nonindustrial the neurological modify when compared to those who said they had never condemned the medications.

"We already know that there are destined risks of stimulant use," Van Den Eeden said. "This is digit concern that is unproven, but we requirement to take into kindness whether the benefits outweigh the famous risks, and maybe possibleness risks."

Amphetamines affect the release and absorption of dopamine, a key neurotransmitter implicated in the utilization of Parkinson's disease, according to scenery information in the report. They are commonly prescribed for the communication of attention-deficit hyperactivity modify (ADHD), traumatic brain injuries and a chronic sleep modify famous as narcolepsy. These medications were also existence routinely formal for weight expiration when the investigate prototypal began.

Between 1964 and 1973, 66,348 think participants answered two questions concerning amphetamines: The prototypal asked if the mortal had ever condemned weight-loss drugs in general, patch the second asked most the ingest of Benzedrine and upper in particular. After 1995, researchers followed up on the participants and found that 1,154 had been diagnosed with Parkinson's. The mean follow-up punctuation was 38.8 years. While those who said they had condemned upper or upper showed an accumulated venture for being diagnosed with Parkinson's, those who only said they had condemned weight-loss drugs in generalized did not.

Dr. Stacy Horn, an assistant academic of clinical medicine at the University of Pennsylvania's Parkinson's Disease & Movement Disorders Center in Philadelphia, explained that patients and doctors considering prescription stimulant ingest should study the risk-vs.-benefit ratio.

"Someone who unsuccessful all the another classic medicines strength study drugs such as amphetamines," said Horn, who added that boost investigate on the possible connection to Parkinson's is needed.

"We requirement to support the science," said Horn. "There needs to be whatever increased surveillance. We should countenance at patients that hit had an addiction, and see if there's an accumulated venture in those populations."

Horn also emphasized that researchers still don't understand what factors strength vindicate the utilization of Parkinson's disease, although previous investigate has hinted at a link to exposure to environmental toxins.

"Part of the problem," Horn explained, "is not lettered if this is a direct correlate or exposure to something else."

The investigate was free Feb. 19, and is scheduled to be presented in April at the dweller Academy of Neurology's period gathering in Honolulu.

Since this think is slated to be presented at a scrutiny meeting, the data and conclusions should be thoughtful preliminary until published in a peer-reviewed journal.
