Treatment-resistant depression in Hispanic patients.

About one-third of patients treated with antidepressants do not respond to initial treatment, and Spanish-speaking Hispanic patients with major depression may exhibit a worse response to initial medication than English-speaking patients. Patients and clinicians should be resolute and patient as different regimens are tried throughout the course of treatment. Other options include electroconvulsive therapy, vagus nerve stimulation, transcranial magnetic stimulation, and the medicinal food L-methylfolate. 2010 Physicians Postgraduate Press, Inc.
