But they do not appear to be helpful in treating drug-induced (levodopa) movements in Parkinson's disease. Not enough evidence was found to show if medical marijuana is helpful in treating motor problems in Huntington's disease, tics in Tourette syndrome, cervical dystonia and seizures in epilepsy. The review is published in the April 29, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology (AAN), and will be presented at the AAN Annual Meeting in Philadelphia, April 26-May 3, 2014, which is the world's largest gathering of neurologists.

"This review by the world's largest association for neurologists is intended to help neurologists and their patients understand the current research on medical marijuana for the treatment of certain brain diseases," said review author Barbara S. Koppel, MD, of New York Medical College in New York and Fellow of the American Academy of Neurology. "The AAN review also highlights the need for more high-quality studies of the long-term efficacy and safety of medical marijuana in the treatment of neurologic diseases."

The AAN review concluded that certain forms of medical marijuana (only in pill or oral spray form) can help treat some symptoms of MS. These include spasticity, certain types of pain (pain related to spasticity, including painful spasms, and painful burning and numbness) and overactive bladder.

Most of the MS studies examined pill or oral spray forms of medical marijuana. There were two studies that examined smoked medical marijuana for treating MS symptoms. However, the studies did not provide enough information to show if smoked medical marijuana is effective. "It's important to note that medical marijuana can worsen thinking and memory problems, and this is a concern since many people with MS suffer from these problems already due to the disease itself," said Koppel.

For Parkinson's disease, the AAN review concluded that medical marijuana in the form of synthetic tetrahydrocannabinol (THC) pills likely does not help relieve abnormal movements that can develop in the late stages of the disease from the drug levodopa, which is the main drug used to treat shaking, stiffness and slowness of movements.

The AAN review also concluded that there is not enough information to show if medical marijuana, including smoked medical marijuana, is safe or effective in these neurologic diseases:
  • Motor symptoms in Huntington's disease
  • Tics in Tourette syndrome
  • Cervical dystonia (abnormal neck movements)
  • Seizures in epilepsy

There are safety concerns with medical marijuana use. Side effects reported in at least two studies were nausea, increased weakness, behavioral or mood changes, suicidal thoughts or hallucinations, dizziness or fainting symptoms, fatigue, and feelings of intoxication. There was one report of a seizure.

Mood changes and suicidal thoughts are of special concern for people with MS, who are at an increased risk for depression or suicide. The studies showed the risk of serious psychological effects is about 1 percent, or one in every 100 people.

In general, medical marijuana is prescribed as a treatment for use only when standard treatment has not helped.

The review is endorsed by the American Autonomic Society, the American Epilepsy Society and the International Rett Syndrome Foundation.

Are we talking about THC or CBD??? I think your findings aren't correct.CBD sure does take away shaking and pain without doing anything to your memory or thinking patterns like THC.It seems like the media are suddenly trying to downplay cannabis's medical wonders.Wonder why that could be? Hmmm.It could have to do with the fact that cannabis is much cheaper than their manmade chemicals...that do in fact do much harm.I'd much rather have the option to decide whats' best for me and my health.I use high CBD oil for everything from diabetes to chronic pancreatitis and so far so good.My quality of life has improved ten fold since off of pain and anxiety medsI don't even need as much insulin as in the past before MM.And those are the facts I've been hearing from so may other people. And furthermore...nobody needs to 'smoke' anything.We have vaporizers now...get up to speed already : ]Peace and Love
