Nearly two-thirds of the marijuana smokers were classified as cognitively impaired based on a several psychological tests, such as information processing speed and verbal memory (all taken at least 12 hours after the patients had last used marijuana).
By comparison, only a third of the non-users had similar mental impairment. The effect was independent of other factors that might affect mental functioning - such as whether the participants drank alcohol or were depressed or anxious.
the potential implications of this pathway in disease progression are supported by animal data showing that cannabinoids are neuroprotective and that CB1 receptor knock-out mice develop severe progressive experimental allergic encephalomyelitis.7 This therapeutic strategy underpins
the ‘Cannabinoid Use in Progressive Inflammatory brain Disease’ (CUPID) study, which is currently evaluating whether THC, one of the naturally occurring CB1 agonists in cannabis, might slow down the progression of disability in subjects with progressive MS.

Fortunately in Canada, a MS patient can be under the care of doctor who is able to prescribe MJ in the proper manner. The patient can also opt for different medications, some of which we know are potent and can cause an array of side effects like....well, decreased blood flow to the brain and slower brain activity. Can you imagine that??!!
So when Dr. Amen publishes the results of his particular tests, they have to be put into perspective. The MS patient has to discuss all options before choosing what route to take and make an informed decision.
Dr. Amen's comment that MS patients have decreased blood flow to the brain treads into the CCSVI spectrum but we'll leave that discussion for another day!
Yes, prescription pain meds are just as bad for the brain as self prescribed (or otherwise) herbal ones. I've had chronic neuropathic pain in my right foot for the last 12 years. I've never taken anything for it, though I was offered neurontin by my neurologist many years ago. However, after looking into neurontin, I decided not to take it. Sometimes the pain is easy to ignore, while at other times it is not. I just deal with it. One thing I've discovered is that if I give myself something else to do, then I tend not to focus on it so much. I find folding origami to be helpful if I'm sitting in an hour long meeting for example.
