Electroconvulsive treatment or medication with benzodiazepines and/or antipsychotics are regarded as standard treatment. Case Presentation We report a case of a patient with catatonic features in whom electroconvulsive treatment and benzodiazepine and/or antipsychotic medications failed to achieve efficacy. Additional treatment with lithium ameliorated catatonia. Conclusion We concluded that lithium is an optional treatment in patients in whom standard treatment failed.
