My brother was in a watch business changing batteries,etc.he had an episode on the job 1 day. He ended up in a psych ward for 3!wks.!since then he is seeing neurogist for different symptoms. Shutting down to talking nonstop to fearful moods could he have been exposed over time to Opioids and maybe fentynel . He has lost some coordination . He stays wrapped up In a blanket saying he is cold .!he is antdidrpressantd and other forms of psychotic drugs. His neurologirts have different DX. And he has an appt with Cleveland clinic. Do u think he could have been exposed with metal to skin contact. He does not take any opioids thank you
