Can anticholinergic medications increase the risk of mild cognitive impairment?
During my medical residency in neurology at the Hospital of Federal Fluminense University (UFF) in Rio de Janeiro/Brazil we often faced the following question: some medications commonly prescribed in routine neurology practice (for patients with Parkinson's syndrome, depression or urinary alterations) inhibited the neurotransmitter acetylcholine, important for the formation and maintenance of memory. Since one of the proposals for the pharmacological treatment of Alzheimer's disease is precisely to increase the concentration of acetylcholine in the brain, the use of drugs that inhibit this neurotransmitter seemed contradictory and threatening to us.
