Why do antipsychotics cause anticholinergic effects?

One particular pharmacologic action of conventional antipsychotics is the ability to block the muscarinic cholinergic receptors in the brain. The strength of antipsychotics’ anticholinergic properties may have a direct relation to their propensity to cause EPS.
