Cannabis May Slow Brain Aging
http://healthland.time.com/2012/10/29/how-cannabinoids-may-slow-brain-aging/?iid=obinsiteThe over 65 voting bloc may be the least likely to support marijuana legalization, but they might find it's in their best interests to do so. Cannabis' ability to help with inflammation and pain is well known.
In addition, not withstanding the stoner memory-loss stereotype, marijuana may help with Alzheimers, brain aging and degenerative diseases. Cases of Alzheimer's disease are expected to triple over the next 50 years.
Since the mid 2000?s researchers have been building an appreciation for the power of marijuana-like substances that make up the brain’s cannabinoid systems. In animal experiments, for example, synthetic compounds similar to THC—marijuana’s main psychoactive component—have shown promise in preserving brain functions. A 2008 study even demonstrated that a THC-like substance reduced brain inflammation and improved memory in older rats.
Activation of cannabinoid receptors can also reduce brain inflammation in several different ways, which may in turn suppress some of the disease processes responsible for degenerative brain diseases such as Alzheimer’s.
Andras Bilkei-Gorzo of the Institute of Molecular Psychiatry at the University of Bonn in Germany and an author of the study, is encouraged by the expanding knowledge of the brain’s cannabinoid system and its potential for leading to new understanding of aging in the brain. “[C]annabinoid system activity is neuroprotective,” he wrote, and increasing it “could be a promising strategy for slowing down the progression of brain aging and for alleviating the symptoms of neurodegenerative disorders.”
Other studies covered in the review showed that mice bred to lack the cannabinoid receptors have better memories early in life but have more rapid cognitive decline as they age, including inflammation in the hippocampus, a key region for memory. “This finding suggests that, at some point during aging, cannabinoid activity helps maintain normal cognitive functions in mice,” says Daniele Piomelli, professor of neurobiology, anatomy and biological chemistry at the University of California – Irvine, who was not associated with the study.

(The researchers) demonstrate that the active component of marijuana, Delta9-tetrahydrocannabinol (THC), competitively inhibits the enzyme acetylcholinesterase (AChE) as well as prevents AChE-induced amyloid beta-peptide (Abeta) aggregation, the key pathological marker of Alzheimer's disease. Computational modeling of the THC-AChE interaction revealed that THC binds in the peripheral anionic site of AChE, the critical region involved in amyloidgenesis. Compared to currently approved drugs prescribed for the treatment of Alzheimer's disease, THC is a considerably superior inhibitor of Abeta aggregation, and this study provides a previously unrecognized molecular mechanism through which cannabinoid molecules may directly impact the progression of this debilitating disease.
These are things the elderly need to know about in order to make informed decisions. Their health may be improved by such actions.

Great news for people like me with Alzheimer's in the family. Bookmarked for later reading 
and feel like I'm about 30. I think there's something to this.
anymore.
