What causes neuroleptic induced deficit syndrome?
It is most often caused by high-potency typical antipsychotics, but can also be caused by high doses of many atypicals, especially those closer in profile to typical ones (that have higher D2 dopamine receptor affinity and relatively low 5-HT2 serotonin receptor binding affinity), like paliperidone and amisulpride.
What is deficit syndrome?
