A study in England has shown an apparent link between anticholinergic drugs and dementia.
An anticholinergic drug blocks the action of the neurotransmitter acetylcholine at synapses in the central and the peripheral nervous system, according to Health Line.
Among the more recognizable names: Clozapine (antipsychotic); darifenacin (bladder); scopolamine (anti-nausea); ipratropium (bronchodilator), and some antihistamines such as diphenhyrdramine (Benadryl).
The study showed that people who took these drugs for three years or more were at a 54 percent greater risk for dementia than someone who takes the medications for three months or less.
The association was strongest for antidepressants, bladder drugs, antipsychotics, and epilepsy medications.
The study did not prove the association, only suggested the possibility. Researchers looked at a database of people and did not conduct a direct study on humans.
