Hi
@DonPepe -- My understanding is Mestinon is meant to increase acetylcholine levels, is that correct? A possible substitute might be Huperzine A, a naturally occurring substance (moss) found in nature which breaks down the enzyme that breaks down acetylcholine, thus increasing acetylcholine levels in the body.
I started taking Huperzine A about 5 years ago, and noticed a notable improvement in my attention span while on the computer within the first 1-2 hours of taking my first dose. I've taken it daily since then, and find it helpful. Since you haven't noticed any improvements with Mestinon yet, and I noticed improvements with Huperzine A within an hour or so, it might be worth considering giving Huperzine A a try and see what happens.
I asked an AI website to describe Huperzine A, and came up with the following:
Huperzine A is a naturally occurring sesquiterpene alkaloid found in the firmoss Huperzia serrata and other species of the Huperzia genus. It is known for its potential neuroprotective properties and is primarily used to enhance memory and cognitive function, particularly in conditions like Alzheimer's disease and age-related memory impairment.
Pharmacology and Mechanism of Action
Huperzine A functions as a reversible inhibitor of the enzyme acetylcholinesterase, which breaks down the neurotransmitter acetylcholine. By inhibiting this enzyme, huperzine A increases the levels of acetylcholine, which is crucial for memory and learning processes. Additionally, it acts as an NMDA receptor antagonist, which may contribute to its neuroprotective effects.
Therapeutic Uses
Huperzine A is used for treating Alzheimer's disease, enhancing memory and learning, and managing age-related memory decline. It has also been explored for treating myasthenia gravis, a muscle disease, and for protecting against nerve-damaging agents like nerve gases. Despite its potential benefits, the quality of clinical evidence supporting its use is variable, and findings from studies should be interpreted with caution.
Synthesis and Availability
Due to the limited natural supply and challenges in cultivating the plant sources, huperzine A is often synthesized in laboratories. It is available over the counter as a dietary supplement in many countries, although it is regulated as a drug for Alzheimer's treatment in China.
Side Effects and Interactions
Huperzine A can cause mild cholinergic side effects such as nausea, vomiting, diarrhea, muscle twitching, and increased saliva production. It may interact with medications for Alzheimer's disease, potentially increasing their effects and side effects. Caution is advised when combining it with other cholinergic or anticholinergic drugs.
Conclusion
Huperzine A is a compound with potential therapeutic benefits for cognitive enhancement and neuroprotection. However, its use should be approached carefully, considering possible side effects and interactions with other medications. Further high-quality studies are needed to fully establish its efficacy and safety profile.
