Obsessive-compulsive disorder (OCD) has high rates of comorbidity with mood disorders, mainly major depressive disorder (MDD). Symptoms of depression are usually secondary to severe and disabling OCD. Electroconvulsive therapy (ECT) has been an effective and well tolerated therapeutic alternative in the management of refractory MDD. Other neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS), have well known efficacy in MDD and also have shown positive results, in clinical trials, treating other psychiatric disorders such as OCD.
To determine the efficacy of combining rTMS, ECT and clomipramine in the treatment of severe OCD with comorbid severe MDD.
The authors report a case of a 54-year-old male patient diagnosed with severe OCD for 23 years. He has been submitted to several drug treatments and intensive cognitive-behavioural therapy (CBT) always with poor response. The patient was admitted in the beginning of 2016 in our inpatient unit. Besides continuing drug treatment (clomipramine IV) and CBT, he was submitted to 12 ECT sessions during one month (3 sessions per week) and to daily sessions of rTMS during the following month.
Outcome measures were obtained using Y-BOCS for OCD and HAM-D for depression.
Our patient responded to ECT with mood improvement after session 4 to full euthymic state at the final session. He also responded well to rTMS with Y-BOCS score reduction.
Combined ECT and rTMS treatment with clomipramine IV and CBT was effective in our patient with a severe form of both disorders (OCD and MDD).
