Preventive measures and treatments for acetylcholine-related disorders often involve pharmacological interventions that either increase acetylcholine levels or enhance its action. For example, acetylcholinesterase inhibitors are commonly used in the treatment of Alzheimer's disease to increase acetylcholine levels in the brain. In myasthenia gravis, medications that reduce the breakdown of acetylcholine at the neuromuscular junction are used to improve muscle strength.
