Could the active ingredient in marijuana, responsible for its characteristic “high,” help turn the tide against the accelerating Alzheimer’s epidemic?
A remarkable study published in the journal Molecular Pharmacology in 2006, found that this long vilified plant contains a compound with not one, but two therapeutic properties ideal for addressing both the surface symptom (memory problems) and root cause (brain plaque) of Alzheimer’s disease. [i] This is an ironic finding, considering that the prevailing stereotype is that using marijuana “fries” the brain, leading to debilitating memory issues.
Researchers discovered that the psychoactive component of marijuana, Î”9-tetrahydrocannabinol (THC), both “competitively inhibits the enzyme acetylcholinesterase (AChE) as well as prevents AChE-induced amyloid Î²-peptide (AÎ²) aggregation.”
On the first account, THC’s ability to inhibit the AChE enzyme, is not unlike the mechanism of action behind most Alzheimer’s drugs on the market today. Drugs like donepezil (trade name Aricept), for instance, by targeting and inhibiting the brain enzyme acetylcholinesterase (AChE), result in an increase in brain levels of this neurotransmitter, which in turn, results in symptom reduction, i.e. improved memory. Donepezil, however, is riddled with controversy due its well-known association with seizures, which likely reflects its intrinsic neurotoxicity. It is, in fact, a chemical in the same general chemical class as venom, insecticides and chemical war agents, such as nerve gas.
On the second account, THC’s ability to prevent the acetylcholinesterase-associated amyloid Î²-peptide (AÎ²) aggregation, i.e. brain plaque, indicates that it may, as the researchers noted, “directly impact Alzheimer’s disease pathology.” In fact, they found “Compared to currently approved drugs prescribed for the treatment of Alzheimer’s disease, THC is a considerably superior inhibitor of AÎ² aggregation, and this study provides a previously unrecognized molecular mechanism through which cannabinoid molecules may directly impact the progression of this debilitating disease.”
What is so encouraging about this research, and which the researchers described as “noteworthy,” is the following:
THC is a considerably more effective inhibitor of AChE-induced AÎ² deposition than the approved drugs for Alzheimer’s disease treatment, donepezil and tacrine, which reduced AÎ² aggregation by only 22% and 7%, respectively, at twice the concentration used in our studies. Therefore, AChE inhibitors such as THC and its analogues may provide an improved therapeutic for Alzheimer’s disease, augmenting acetylcholine levels by preventing neurotransmitter degradation and reducing AÎ² aggregation, thereby simultaneously treating both the symptoms and progression of Alzheimer’s disease.
THC, of course, is only one of a wide range of cannabinoids in the plant marijuana. Not only is there already plentiful information on the neuroprotective properties of marijuana compounds, but there is also a sizeable body of clinical and/or biomedical research indicating the medicinal value of this plant in over 150 health conditions.
