Mental Disorders in Offspring of Parents with Bipolar Disorder / 신경정신의학

OBJECTIVES: Information on the specificity of associations between parents with bipolar disorder (BPD) and risk of psychopathology in their offspring is limited. The aim of this study was to examine the prevalence of mental disorders in the offspring of individuals with BPD in South Korea. METHODS: The sample consisted of 100 child and adolescent offspring (aged 6.0-18.9 years) from 65 nuclear families having at least one parent with BPD. Probands, offspring, and biological co-parents were interviewed using a semi-structured diagnostic interview and the offspring were evaluated using the Korean version of the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL). RESULTS: Sixty one of the 100 participants met the criteria for at least one mental disorder. Of these, 35 participants had a mood disorder, 35 had an anxiety disorder, and 29 had attention-deficit hyperactivity disorder (ADHD). Thirty nine of the offspring had no psychiatric diagnosis. Of the 35 with a mood disorder, 16 (45.7%) had comorbid ADHD and 18 (51.4%) had comorbid anxiety disorders. CONCLUSION: Offspring of parents with BPD are at high risk for mental disorders. These findings further support the heredity of BPD and indicate the need for early identification and treatment.

A General Hospital-Based Model for Early Detection of Depression in the Geriatric Patients with Chronic Medical Diseases

The geriatric patients with chronic physical diseases are frequently associated with the continuous clusters of depression including nonpathological sadness, subsyndromal depression, minor depressive disorder, and major depressive disorder. Because of the complex and reciprocal relationships among depression, elderly, and chronic physical diseases, screening approaches with specific nosological methods should be needed in the realm of early detection of depression. Cognitive decline is frequently manifested in geriatric depression with medical or neurological diseases. Also, somatic symptoms of depression or emotional symptoms of physical diseases can play a role as a hampering factor in the early detection of depression. Furthermore, after-care has been regarded as an essential factor of depression screening in the geriatric patients with chronic physical diseases. We reviewed the most popular examples of integrated medicine for depression in primary care. Thus, we propose a general hospital-based model for early detection of depression which includes favorable response loop between screening and therapeutic intervention. Our model can be a basis for evidence-based detection and after-care for depression in the geriatric patients with chronic medical diseases.

Survey of Depression in the Elderly Patients with Chronic Obstructive Pulmonary Disease / 신경정신의학

OBJECTIVES: Depression is commonly comorbid in the elderly patients with physical illness. This study examined the prevalence of depression in the elderly with chronic obstructive pulmonary disease (COPD). METHODS: The eighty-seven patients with COPD were enrolled. The subjects are over 60 years old. The medical and psychiatric history, Hamilton Rating Scale for Depression (HDRS), Patient Health Questionnaire-9 (PHQ-9), Patient Health Questionnaire-2 (PHQ-2), Geriatric Depression Scale-Short form Korean (GDS-SF-K), Mini-Mental Status Exam Korean version (MMSE-KC) were investigated. Global Initiative for Chronic Obstructive Lung Disease (GOLD), which predict the severity of COPD, also investigated. RESULTS: The prevalence of depression was estimated to be 24.7% (male 19.3% ; female 35.7%) in HDRS, 31.0% (male 24.6% ; female 43.3%) in PHQ-9, 8.0% (male 10.5% ; female 3.3%) in PHQ-2, 23.0% (male 17.5% ; female 33.3%) in GDS-SF-K. The severity of COPD (GOLD) was associated with the prevalence of depression (HDRS, p=0.027 ; PHQ-9, p=0.045 ; PHQ-2, p=0.112 ; GDS-SFK, p=0.089). CONCLUSION: The prevalence of elderly depression with COPD ranged from about 20% to 30%, the prevalence of depression is nearly two times more common in women. The severity of COPD (GOLD) was associated with the prevalence of depression. The self-reporting scale, such as GDS-SF-K, PHQ-9 and PHQ-2 is the effective screening test of depression.

The Association Study between Mood Disorder Questionnaire and Bipolar Spectrum Disorder in Major Depressive Disorder / 신경정신의학

OBJECTIVES: This study was performed to evaluate the frequency of bipolar spectrum disorder (BSD) among patients who have been diagnosed with major depressive disorder. In addition, authors assessed the practical usefulness of the Mood Disorder Questionnaire (MDQ) to investigate the frequency of bipolar spectrum disorder in major depressive disorder. METHODS: The participants were 70 depressive patients who have never been diagnosed with bipolar disorders. The subjects were interviewed for diagnosis using the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision criteria and the Mini-International Neuropsychiatric Interview to exclude bipolar disorders from the subjects. BSD criteria (as defined by Ghaemi, et al. 2002), and Korean version of the Mood Disorder Questionnaire (K-MDQ) was used to investigate their bipolarity. Data were collected including family history of affective disorder, number of previous depressive episode, age of onset, history of suicide attempt, comorbid psychiatric illness, and drug and alcohol use. RESULTS: Among 70 subjects, 25 patients (35.7%) were classified as having bipolar spectrum disorder on BSD criteria, while other 45 patients (64.3%) as unipolar depression. Among the 25 patients who meet the BSD criteria, 24 patients (34.3%) scored more than 7 and only 1 patient (1.4%) scored less than 6 on K-MDQ. Among the 45 patients who don't meet BSD criteria, 40 patients (57.1%) scored less than 6 and only 5 patients (7.1%) scored more than 7 on K-MDQ. Early age of onset, recurrent depressive episode, brief depressive episode, bipolar family history, history of suicide attempt, antidepressant induced hypomania, hyperthymic temperament, atypical depressive symptom, psychotic depressive symptom, and antidepressant "wear off" were found to be highly related with MDQ positive subjects and BSD subjects among the depressive subjects. CONCLUSION: The result of this study demonstrates the high frequency of BSD in depressive patients who have never been diagnosed with bipolar disorders. Some BSD criteria can be used to differentiate BSD subjects from the subjects with major depressive disorder. Also these results indicate that K-MDQ is useful for screening of bipolar spectrum disorder.

Association between Intracellular Infectious Agents and Schizophrenia

OBJECTIVE: A number of studies have reported association between Toxoplasma gondii (T. gondii) and Chlamydia infection and the risk of schizophrenia. The aim of the present study was to compare the prevalence of T. gondii and Chlamydia infection between the schizophrenia and normal control subjects and to compare the clinical features between seropositive and seronegative schizophrenia patients. METHODS: The rate of serum reactivity to T. gondii, Chlamydia trachomatis (C. trachomatis), Chlamydia pneumonia in 96 schizophrenia and 50 control subjects was investigated using enzyme-linked immunosorbent assay and indirect fluorescent antibody technique. The clinical symptoms of the schizophrenia patients were scored with Positive and Negative Syndrome Scale and a comparative analysis was carried out. RESULTS: A significant positive association between immunoglobulin G (IgG) antibodies to T. gondii and C. trachomatis in schizophrenia was found, and the odds ratio of schizophrenia associated with IgG antibody was found to be 3.22 and 2.86, respectively. The Toxoplasma-seropositive schizophrenia patient had higher score on the negative subscale N1 and N7 and general psychopathology subscale G13, while C. trachomatis-seropositive schizophrenia patient had higher score on the general psychopathology subscale G10. CONCLUSION: The results from the present study suggest significant association between T. gondii, C. trachomatis infection and schizophrenia. In future, further studies are needed to elucidate the correlation between the two types of infection and schizophrenia.

Impact of Adenotonsillar Hypertrophy on Sleep and Attention Deficit-Hyperactivity Symptoms in Children / 신경정신의학

OBJECTIVES : Adenotonsillar hypertrophy is one of the principal causes associated with snoring, sleep apnea, and restless sleep. These sleep-disordered breathing (SDB) is associated with hyperactivity, rebellious behavior, aggressiveness, enuresis, inattention, social withdrawal, and learning difficulties. The purpose of this study was to assess the impact of adenotonsillar hypertrophy on attention deficit hyperactivity symptoms and sleep-related symptoms in children by standard tests. METHODS : Children aged 5 through 15 years old, a total of 65 who were scheduled for Tonsillectomy and Adenoidectomy, were studied. The control group consisted of 30 healthy children of the same age. In both groups, attention-deficit hyperactivity dis-order (ADHD) was evaluated by Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL). The degree of inattention, hyperactivity and sleep-related symptoms was evaluated by Korean ADHD Rating Scales (K-ARS), ADHD diagnostic system (ADS) and pediatric sleep questionnaire. The K-ARS and sleep questionnaire were completed by the parents of the children. RESULTS : Acording to K-SADS-PL, 23 subjects out of 65 subjects in the patient group and 2 subjects out of 30 subjects in the control group were diagnosed with ADHD. According to sleep questionnaires, the patient group reported significantly more problems than the control group. The patients had significantly higher cumulative questionnaire scores than the control group. In linear regression analysis, the cumulative score of sleep questionnaire was associated with inattention subscale scores, hyperactivity/impulsivity subscale scores and the total score of K-ARS, and also with the response time and the standard deviation of response time of ADS. In relation to ADHD, the patient group had significantly higher ADHD scores in K-ARS inattention subscale and significantly slower response time in ADS compared to the control group. Comparing SDB children without ADHD and the control group without ADHD by excluding ADHD children in both groups, SDB children without ADHD did not show significantly higher scores in K-ARS but did show significantly slower ADS response time. CONCLUSION : Children with adenotonsillar hypertrophy are associated with increased SDB and ADHD symptoms. Therefore they may need intensive treatment such as surgical intervention.
