Abstract

Background: Prevalence of depression comorbid with neurologic disorders such as Alzheimer' disease (AD), Parkinson's disease (PD) and vascular dementia (VD) is higher than that of primary depression. Antidepressant medications, suggested by many researches for depression comorbid with neurologic disorders such as AD, PD and VD, are mainly selective serotonin reuptake inhibitors (SSRI). Objective: The primary objective of this study is the evaluation of antidepressant drug therapy for AD, PD and VD. Method: This study was a retrospective study based on medical records, carried out for 3 years and 6 months (Jan. 2007~Jul. 2010). Patients, diagnosed as comorbid depression through Beck Depression Inventory (BDI), Cornell Depression Scale (CDS), Geriatric Depression Scale (GDS) among neurologic out-patients of Chungnam National University Hospital because of AD, PD and VD, were selected. The results were evaluated by efficacy and safety of antidepressant drug therapy. Results: In result, the prescribing rates of antidepressants were 30%, 55% and 40% for each AD, PD and VD. Depression cure rates of patients receiving antidepressants vs patients not receiving antidepressants were 40% vs 39%, 33% vs 23% and 38% vs 30% for AD, PD and VD. The frequencies of prescriptoin of SSRI were 21%, 11% and 27% for each AD, PD and VD. The frequencies of prescriptoin of benzodiazepine (BZD) was 61%, 82% and 61% for each AD, PD and VD. The ratio of single BZD prescription was more than that of combination prescription of antidepressants. Tricyclic antidepressants (TCA) were rarely prescribed. The rate of patients with BZD-related side effects was 54%. The most frequent side effects of BZD were dizziness (30%), drowsiness (21%) and headache (16%). Side effects of SSRI were rare. Conclusion: In conclusion, the frequencies of prescription of antidepressants were not common for AD, PD and VD. There was little difference in depression cure rate between patient receiving antidepressants and not receiving. Even though SSRI has to be the highest priority of usage, the frequencies of prescription of SSRI were lower than those of BZD. Additional researches and efforts are required to improve antidepressant drug therapy for neurologic disorders such as AD, PD and VD.
