To explore the relationship between suicide risk, the perception of social support and quality of life (QoL), and with the clinical variables of adult people with epilepsy (PWEs).

A total of 98 consecutive PWEs cared for in the outpatient setting, with a mean age of 48.1±15.9 years, having had epilepsy for 26.4±16.4 years and 48 (48.9%) female cases participated in this study. The MINI suicide module, the Social support satisfaction scale (SSSS), the Quality of life in epilepsy inventory (QOLIE-31), and the Hospital anxiety and depression scale (HADS) were used. A logistic regression was conducted to assess the factors associated with the suicide risk.

Suicide risk was present in 33 cases. Younger age, earlier age at epilepsy onset, depression and anxiety in the HADS scale, and lower MMSE, QOLIE-31, and SSSS scores were significantly associated with suicide risk in the univariate analysis. The logistic regression analysis identified that lower scores in the MMSE (OR 0.826, 95%CI 0.705-0.969), presence of anxiety (OR 0.197, CI 0.073-0.530), and a low perception regarding satisfaction with family (OR 0.953, CI 0.920-0.988) are the factors associated with the highest risk of suicide.

Suicide risk and recurrence of a suicide attempt was high in the PWEs. Suicide risk was associated with clinical variables, the presence of anxiety and the perception of less social support from the family.
