BACKGROUND: Depression and suicide are common in neurological disorders. However, their reported frequencies have varied widely due to heterogeneities in methodology and assessment timing. We evaluated the frequencies of current depression and suicidality in patients with epilepsy, Parkinson's disease (PD), and ischemic stroke (IS).
METHODS: We enrolled patients who visited a tertiary care hospital in Seoul between January and December 2013. All of the patients completed the Beck Depression Inventory (BDI) and the Hospital Anxiety and Depression Scale-Depression subscale (HADS-D). Any patient with depressive symptoms (defined as a total HADS-D or BDI score of ≥9 or ≥17, respectively) was reassessed with a structured psychiatric interview based on the Mini International Neuropsychiatric Interview Plus 5.0.0 (MINI).
RESULTS: In total, 305 patients were recruited, comprising epilepsy (n=92, 30.2%), PD (n=99, 32.4%), and IS (n=114, 37.4%). Depressive symptoms were exhibited by 52 epilepsy patients (56.5%), 56 PD patients (56.6%), and 54 IS patients (47.4%), and these were further evaluated with the aid of the MINI. Seven epilepsy patients were diagnosed as major depressive disorder (MDD), five as dysthymic disorder (DD), and nine as depressive disorder not otherwise specified (DDNOS). Twelve PD patients were diagnosed as MDD, 7 as DD, and 10 as DDNOS. Ten stroke patients were diagnosed as MDD, 7 as DD, and 11 as DDNOS. Most patients with depressive symptoms (91.4%) exhibited suicidality.
CONCLUSIONS: Patients with epilepsy, PD, and IS frequently exhibit depression and suicidality. Neurologists should always be concerned about comorbid psychiatric problems when they see patients with neurological disorders.
