Marijuana and Alzheimers disease

Researchers at the Scripps Research Institute have found that the active ingredient in marijuana may help prevent Alzheimer's disease. Tetrahydrocannabinol or THC as it is better known, apparently inhibits the formation of amyloid plaque. In plaques, the main protein component is called beta-amyloid, which is produced from a larger protein called beta-amyloid precursor protein. Ever since the discovery of these proteins researchers have been attempting to discover their role in the disease. This study has found that THC is much more effective at breaking down the plaque than some of the FDA approved medications currently available for treating Alzheimer's disease.

THC (an active ingredient in marijuana) may prevent the progression of Alzheimer's Disease by:

1) Preventing the breakdown of acetylcholine, an important neurotransmitter that allows the brain to function, more effectively than commercial drugs, and

2) Blocking clumps of protein that can inhibit memory and cognition in Alzheimer's patients.
