Presentation and review of a case.

A 55-year-old woman diagnosed with recurrent depressive disorder with worsening in the last 4 years.

Clinical depressive Sadness, spontaneous crying in the form of access, apathy, isolation and clinofilia desires, complaints mnemonic deficits and complete anhedonia. Obsessional symptoms compulsive as more repetitive behaviors of obsessive ideas, which repeats incessantly despite checking, that does not prepare or calm. The patient has not responded to any pharmacological strategy, despite using full doses and combinations of antidepressant, but euthymics more antipsychotics (sertraline, fluoxetine, reboxetine, venlafaxine, bupropion, lithium, valproic acid, lamotrigine, risperidone, quetiapine, trifluoperazine, clotiapine). For this reason, it was decided to start treatment with ECT, progressively responds in each session, after 8 sessions the patient is euthymic, it has resumed normal activities, no obsessive or psychotic symptoms.
