Why is anticholinergic bad for elderly?
The central nervous system and the brain are very sensitive to anticholinergic side effects due to fewer cholinergic neurons or receptors in the brain of older individuals. In addition, the liver and kidney have less ability to break down and excrete medications. Also, drugs can cross more easily into the brain.
What are symptoms of anticholinergic toxicity?

How long does anticholinergic toxicity last?
In the case of overdose, atropine and scopolamine cause anticholinergic syndrome. The anticholinergic toxicity usually occurs within 30–60 min after consumption of the plant, and the symptoms can last for 24–28 h due to delayed gastric emptying caused by the anticholinergic alkaloids.
How do you reverse anticholinergic toxicity?
