In a way that relates to the treatment of mental health issues or the study of the mind.
The patient was treated psychiatrically to address his mental health concerns.
Psychiatrically → It is formed from "psyche" (from Greek "psukhē", meaning soul or mind) and "iatric" (from Greek "iatros", meaning physician) combined with the adverbial suffix "-ally" (meaning in a manner). The word refers to something done in a manner related to the treatment of the mind or soul.
Think of 'psyche' as relating to the mind and 'iatric' as relating to healing, so 'psychiatrically' means acting in a way that pertains to healing the mind.
