Hi @henrymedford, welcome to Taper Community!
Your son is fortunate to have such a caring, loving, and concerned parent. Yes, large reductions of antipsychotics can cause those kinds of issues.
We recommend Hyperbolic tapering here at TC - monthly reductions of no more than 10% of the previous month's dose. The reductions will therefore get smaller and smaller as time goes on. The greatest changes in receptor occupancy happen at very low doses, so tapering this way is safer and easier on the brain. Some members can only taper by 5% or even less. Everyone is different in what their own body can handle. They key is to listen to your body and adjust your taper accordingly. If symptoms become severe, then that is a sign you need to slow your taper down by holding longer between reductions or reducing by a lesser amount. We don't want to keep pushing through symptoms. Slower is faster. 👍
