Hypoactivity is an inhibition of behavioral or locomotor activity.[1]
Hypoactivity is a characteristic effect of sedative agents and many centrally acting anesthetics. Other drugs such as antipsychotics, which are used to treat delusions and hallucination (symptoms of psychosis),[2] and mCPP also produce this effect, often as a side effect.
It may be a characteristic symptom of the inattentive type of ADHD[3] (ADHD-PI) and sluggish cognitive tempo.
