SUNDAY, Feb. 20 (HealthDay News) -- Taking medication 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 relationship and further enquiry is warranted.

Study author author K. Van Den Eeden, a grownup investigator at the Division of Research at Emperor Permanente Northern California, in Oakland, said that grouping who reported 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 verify into consideration whether the benefits outweigh the famous risks, and maybe possibleness risks."

Amphetamines change the promulgation and absorption of dopamine, a key neurotransmitter implicated in the utilization of Parkinson's disease, according to background aggregation in the report. They are commonly prescribed for the treatment of attention-deficit hyperactivity modify (ADHD), traumatic mentality injuries and a chronic rest modify famous as narcolepsy. These medications were also existence routinely prescribed for weight expiration when the investigate prototypal began.

Between 1964 and 1973, 66,348 think participants answered digit questions concerning amphetamines: The prototypal asked if the person had ever condemned weight-loss drugs in general, patch the second asked about 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 simply said they had condemned weight-loss drugs in generalized did not.

Dr. Stacy Horn, an supporter professor 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 failed all the other classic medicines might study drugs much as amphetamines," said Horn, who additional that further 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 wager if there's an accumulated venture in those populations."

Horn also emphasized that researchers ease don't see what factors might vindicate the utilization of Parkinson's disease, though previous investigate has hinted at a unification to danger to environmental toxins.

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

The investigate was released Feb. 19, and is regular 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 medical meeting, the data and conclusions should be considered preliminary until published in a peer-reviewed journal.
