Gender Differences in Depressive Symptom Profile: Results from Nationwide General Population Surveys in Korea

This study investigated gender differences in symptom profiles of major depressive disorder (MDD) in the Korean general population. Data were pooled from the series of nationwide Korean Epidemiologic Catchment Area surveys conducted in 2001, 2006 and 2011, respectively. Of the 18,807 participants, 507 (397 women and 110 men) were diagnosed with MDD within the prior 12 months. In agreement with previous studies, women with MDD appeared to be more vulnerable to experiencing atypical depressive episodes defined as depression with two or more symptoms of fatigue, increased appetite and hypersomnia (P < 0.001). In terms of individual symptoms, female gender was significantly related with higher prevalence of fatigue (P = 0.008), hypersomnia (P = 0.001), noticeable psychomotor retardation (P = 0.029) and suicidal attempts (P = 0.016) with adjustment for birth cohort effect, partner status, and employment status. In the same analysis, men with MDD appeared more vulnerable to decreased libido than women (P = 0.009). This is the first report to demonstrate gender differences in symptomatology of MDD in the general Korean population, and the results are comparable to previous investigations from western societies. Assumingly, the intercultural similarity in female preponderance to atypical depression might reflect the common biological construct underlying the gender difference in mechanism of MDD. In clinical settings, gender differences of MDD should be carefully considered, because these features could be related with treatment response and drug side effects.

Frequency of non-motor symptoms in Peruvian patients with Parkinson's disease / Frecuencia de síntomas no motores en pacientes peruanos con enfermedad de Parkinson

Introduction: Non-motor symptoms in Parkinson's disease are often not well recognized in clinical practice. Non-motor symptoms questionnaire (NMSQuest) is a simple instrument that allows patients or caregivers to report non-motor symptoms in a practical manner. Objective: We attempted to determine the prevalence of non-motor symptoms in three hundred Parkinson's disease outpatients. Results: The mean total non-motor symptoms was 12.41, ranging from 0 to 27 of a maximum of 30. At least one was present in 99.3% of patients. A progressive increase in mean total score was observed across each 5-year interval. Depression domain scored the most “positive” answers while urinary and anxiety /memory were secondly and thirdly most prevalent respectively. Conclusion: The large number of patients included in this study allowed evaluation of the occurrence of non-motor symptoms in early and advanced disease in addition to the relationship of these kinds of symptoms with progression of disease. .

Introducción: Los síntomas no motores en la enfermedad de Parkinson son frecuentes y no bien reconocidos en la práctica clínica. El Cuestionario de Síntomas No Motores (NMSQ) es un instrumento simple que permite a los pacientes o cuidadores reportarlos de una manera práctica. Objetivo: Intentamos determinar la prevalencia de síntomas no motores en trescientos pacientes con enfermedad de Parkinson. Resultados: El promedio total de SNM fue de 12.41 con un rango de 0 a 27 de un máximo de 30. Al menos uno estaba presente en el 99,35 de los pacientes. Un incremento progresivo del score promedio total se observa lo largo de intervalos de 5 años. Los síntomas más frecuentes fueron depresión, incontinencia urinaria y ansiedad respectivamente. Conclusión: La gran cantidad de pacientes evaluados permitió la evaluación de los SNM en fases tempranas y avanzadas de la enfermedad y la relación de los mismos con la progresión de la enfermedad .
