treatment-refractory
Referring to psychiatric conditions that do not respond adequately to standard treatments despite appropriate trials.
Full Definition
Treatment-refractory describes psychiatric conditions that fail to respond to conventional therapeutic interventions after adequate trials of appropriate medications or psychotherapies. In depression research, treatment-refractory typically refers to patients who have not responded to multiple antidepressant trials of sufficient dose and duration. For schizophrenia, treatment-refractory usually indicates lack of response to adequate trials of at least two different antipsychotic medications. The definition often includes specific criteria regarding the number of treatment attempts, duration of trials, and degree of symptom persistence. Treatment-refractory patients represent a particularly challenging population for clinicians and an important target for novel therapeutic development. Research in this area focuses on alternative treatment mechanisms, combination strategies, and interventions like electroconvulsive therapy or transcranial magnetic stimulation.
