Many people can eventually be restarted on a lower dose of antipsychotic. [2] [3] As of 2011, among those in psychiatric hospitals on antipsychotics about 15 per 100,000 are affected per year (0.015%). [1] In the second half of the 20th century rates were over 100 times higher at about 2% (2,000 per 100,000). [1]

[5] For reference, the typical antipsychotic haloperidol tends to block about 80% of D2 receptors at doses ranging from 2 to 5 mg per day. [5]
