Aim of the study:
The first line medicinal treatment of Obsessive Compulsive Disorder includes Selective Serotonin Reuptake Inhibitors (SSRIs).Researchers have shown that there is a correlation between the trace elements deficiency such as selenium and mental disorders and mood, since selenium is a safe and non-tolerable side-effect supplementation that may be useful as an adjunctive treatment with SSRIs.

Subject or material and methods:
Thirty-two patients with a treatment-resistant obsessive-compulsive disorder were selected and randomly entered into two groups: intervention and control, while both groups continued to consume SSRI drugs according to the current procedure. The intervention group received one 200 mcg selenium capsule daily and each daily control group received one capsule of placebo for 6 weeks.

Results:
Y-BOCS scores decreased at the end of the sixth week in both groups, but this reduction was significantly lower in the selenium group (P = 0.01). Selenium was well tolerated and there was no significant difference between the two groups in the incidence of side effects

Discussion:
The results of this study indicate that selenium as an adjunctive treatment with SSRIs improves symptoms

Conclusions:
Selenium can be as new drug for treatment of Refractory OCD.
