Marijuana May Present Or Reverse Memory Loss In Alzheimer's

"Marijuana's memory paradox" from MSN reports that marijuana may provide beneficial effects for Alzheimer's patients as the ingredients in cannibis - THC may be helpful in preventing and even reversing the memory loss associated with Alzheimer's.  

But new research suggests that one of the active ingredients in marijuana—THC—and similar compounds could possibly prevent or even reverse one of the most devastating memory disorders of all: Alzheimer's disease.

In a paper published in the December 2008 issue of the journal Neurobiology of Aging, researchers found that a compound that affects the same brain receptors as THC reduced brain inflammation and improved memory in older rats. (The rodents were the human equivalent of age 65 to 70.) Although there's debate over the role played by inflammation in Alzheimer's, many researchers believe it's an important part of the process that causes dementia.
