Thanks for reporting on this. But psychosis and akathisia are two different things. Mantel describes it well here: https://twitter.com/Telegraph/status/1388469833851936771

"No physical pain has ever matched that morning's uprush of killing fear, the hammering heart. You are impelled to move, to pace in a small room. You force yourself down into a chair, only to rise out of it. You choke; pressure rises inside your skull. You hands pull...

at your clothing and tear at your arms …" The answer was Largactil, a heavy-duty anti-psychotic, "which knocked me into insensibility."

She was given another antipsychotic here, perhaps to replace the first one. But antipsychotics are definitely not akathisia treatment!

Akathisia is often *caused* by antipsychotics. Which is maybe the confusion.

Alternatively, if akathisia is misdiagnosed as a separate psychiatric condition, patients may be given antipsychotics. But that's an error! It's not because akathisia=psychosis

As one can see by Mantel's description. Akathisia is a separate beast altogether. Source: https://www.theguardian.com/theguardian/2009/sep/12/hilary-mantel-booker-prize-interview
