Issues in the pharmacological treatment of obsessive–compulsive disorder

Aims:  Obsessive–compulsive disorder (OCD) preferentially responds to a class of antidepressants called serotonin reuptake inhibitors (SRI). This review discusses certain issues unique to pharmacological treatment of OCD: choice of SRI, dose and duration of treatment, options after first failed SRI trial and treatment of SRI non‐responders.

Indian psychiatric epidemiological studies: learning from the past.

The objective of this paper is to provide a systematic review on the epidemiology of psychiatric disorders in India based on the data published from 1960 to 2009. Extensive search of PubMed, NeuroMed, Indian Journal of Psychiatry website and MEDLARS using search terms “psychiatry” “prevalence”, “community”, and “epidemiology” was done along with the manual search of journals and cross-references. Retrieved articles were systematically selected using specific inclusion and exclusion criteria. Epidemiological studies report prevalence rates for psychiatric disorders varying from 9.5 to 370/1000 population in India. These varying prevalence rates of mental disorders are not only specific to Indian studies but are also seen in international studies. Despite variations in the design of studies, available data from the Indian studies suggests that about 20% of the adult population in the community is affected with one or the other psychiatric disorder. Mental healthcare priorities need to be shifted from psychotic disorders to common mental disorders and from mental hospitals to primary health centers. Increase in invisible mental problems such as suicidal attempts, aggression and violence, widespread use of substances, increasing marital discord and divorce rates emphasize on the need to prioritize and make a paradigm shift in the strategies to promote and provide appropriate mental health services in the community. Future epidemiological research need to focus on the general population from longitudinal prospective involving multi-centers with assessment of disability, co-morbidity, functioning, family burden and quality of life.

Tsunami: psychosocial aspects of Andaman and Nicobar Islands. Assessments and intervention in the early phase

The aim of this paper is to describe the activities and observations of the team from National Institute of Mental Health and Neuro Sciences (NIMHANS) Bangalore, India in the Andaman and Nicobar Islands during the early phase of the Tsunami disaster in January and February 2005. The activities comprised mental health consultation at camps, community sensitization, mental health services to the students and children, teachers orientation sessions and training of non-governmental organization [NGO] functionaries. Initial assessment reveals 5–8% of the population were suffering from significant mental health problems following the early phase of the disaster. This may increase in the aftermath of the early relief phase. Psychiatric morbidity is expected be around 25–30% in the disillusionment phase. High resilience was seen in the joint family system of tribal Nicobarese during early phase of disaster. In developing countries like India, limited availability of mental health professionals and poor knowledge about disaster mental health among the medical and para-medical staff, may lead to poor psychosocial rehabilitation of the survivors. To respond to a high magnitude natural disaster like a tsunami, the disaster mental health team must be able to understand the local culture, traditions, language, belief systems and local livelihood patterns. They also need to integrate with the network of various governmental and non-governmental organizations to cater to the needs of the survivors. Hence the presence of a disaster mental health team is definitely required during the early phase of the disaster in developing countries.

Impact of age of onset of illness on clinical phenotype in OCD

BACKGROUND This study aims to examine the demographic, clinical and comorbid patterns in a large sample of adult OCD subjects at a specialty OCD clinic in India. METHODS Consecutive patients (n=545) who consulted a specialty OCD Clinic over 5 years at a large psychiatric hospital in India were evaluated with the Mini International Neuropsychiatric Interview, the Yale-Brown Obsessive-Compulsive Scale, and the Clinical Global Impression scale. RESULTS Earlier age onset of OCD (years) was characterized by male preponderance (19.61±7.98 vs. 25.19±10.39, U=23453.5, p=<0.001), positive family history of OCD (19.60±10.02 vs. 22.27±9.20, U=16590.5, p<0.001) and presence of tic disorder (16.28±8.21 vs. 22.01±9.38, OR=0.86, p=0.001). In addition, early age of onset was associated with presence of sexual obsessions (18.92±7.49 vs. 22.88±9.82, OR=0.96, p=0.02), hoarding (19.61±9.32 vs. 22.21±9.36, OR=0.95, p=0.009), repeating rituals (19.76±8.37 vs. 23.29±9.84, OR=0.95, p=0.006) and need to touch compulsions (16.40±7.19 vs. 22.36±9.43, OR=0.89, p<0.001). CONCLUSIONS Our findings from a large sample not only confirm that early onset OCD could be a valid and distinct subtype of OCD but also support the cross-cultural similarity of early onset phenotype.

Comparative Study of Psychiatric Morbidity among the Displaced and Non-Displaced Populations in the Andaman and Nicobar Islands following the Tsunami

OBJECTIVE The objective of this study was to compare the psychiatric morbidity between the displaced and non-displaced populations of the Andaman and Nicobar Islands during the first three months following the 2004 earthquake and tsunami. METHODS The study was conducted at the 74 relief camps in the Andaman and Nicobar Islands. Port Blair had 12 camps, which provided shelter to 4,684 displaced survivors. There were 62 camps on Car-Nicobar Island, which provided shelter to approximately 8,100 survivors who continued to stay in their habitat (non-displaced population). The study sample included all of the survivors who sought mental health assistance inside the camp. A psychiatrist diagnosed the patients using the ICD-10 criteria. RESULTS Psychiatric morbidity was 5.2% in the displaced population and 2.8% in the non-displaced population. The overall psychiatric morbidity was 3.7%. The displaced survivors had significantly higher psychiatric morbidity than did the non-displaced population. The disorders included panic disorder, anxiety disorders not otherwise specified, and somatic complaints. The existence of an adjustment disorder was significantly higher in the non-displaced survivors. Depression and post-traumatic stress disorder (PTSD) were distributed equally in both groups. CONCLUSIONS Psychiatric morbidity was found to be highest in the displaced population. However, the incidence of depression and PTSD were distributed equally in both groups. Involvement of community leaders and survivors in shared decision-making processes and culturally acceptable interventions improved the community participation. Cohesive community, family systems, social support, altruistic behavior of the community leaders, and religious faith and spirituality were factors that helped survivors cope during the early phase of the disaster.

Impact of depressive and anxiety disorder comorbidity on the clinical expression of obsessive-compulsive disorder.

BACKGROUND The identification of distinct subtypes based on comorbidity offers potential utility in understanding variations in the clinical expression of obsessive-compulsive disorder (OCD). Hence, we examined the hypothesis whether patients with OCD with major depressive disorder (MDD) or anxiety disorder comorbidity would differ from those without in terms of phenomenology. METHODS A total of 545 consecutive patients who consulted a specialty OCD clinic during the period 2004 to 2009 at a psychiatric hospital in India formed the sample. They were evaluated with the Yale-Brown Obsessive-Compulsive Scale (YBOCS), the Mini International Neuropsychiatric Interview, and the Clinical Global Impression scale. RESULTS Among 545 patients, 165 (30%) had current MDD, and 114 (21%) had current anxiety disorder comorbidity. Patients with OCD with MDD were mostly women who had a greater severity of OCD symptoms, more of obsessions (especially religious), greater occurrence of miscellaneous compulsions (need to confess or need to touch), higher suicidal risk, and past suicidal attempts. Patients with OCD with anxiety disorder had an earlier onset of illness that was associated with prior life events, less of compulsions, more of aggressive and hoarding obsessions, pathologic doubts, checking, and cognitive compulsions. CONCLUSIONS Obsessive-compulsive disorder, when comorbid with MDD, is more severe and is associated with higher suicidal risk. On the other hand, anxiety disorder comorbidity seems to influence not so much the morbidity but the phenotypic expression of OCD.

Clinical predictors of response to treatment in catatonia

OBJECTIVE This study aims at identifying predictors of treatment response to lorazepam in catatonia. METHODS The clinical charts of 107 inpatients, admitted over duration of 2 years, with a primary diagnosis of catatonia were examined for response to lorazepam trial. Trial was considered as having received 3-6 mg per day of lorazepam for at least 3 days. RESULTS Out of these 107 patients, 99 received lorazepam and 8 received electroconvulsive therapy as the first line of management. There were 32 responders and 67 nonresponders to lorazepam. The nonresponders were characterized by rural background (85.1% vs. 62.5%, P=.01), longer duration of catatonic symptoms (108.88 vs. 25.12 days, P=.018), mutism (63.6% vs. 31.3%, P=.02) and presence of first-rank symptoms like third-person auditory discussing-type hallucinations (16.4% vs. 12.0%, P=.03) and made phenomena (7.5% vs. 0%, P=.04). The presence of waxy flexibility (12.5% vs. 4.5%, P=.03) predicted good response. CONCLUSIONS This study identifies that longer duration of illness, presence of catatonic sign of mutism and certain specific phenomena like third-person auditory hallucinations and made phenomena predicted poor response to lorazepam in catatonia. This could provide insight into the prediction and planning of the appropriate treatment strategies in this psychiatric emergency.

Clinically significant hoarding in obsessive-compulsive disorder: results from an Indian study

BACKGROUND Hoarding is frequently conceptualized as a symptom of obsessive-compulsive disorder (OCD), but recent evidence indicates that, in most cases, hoarding may be better conceptualized as a distinct disorder that can coexist with OCD. Most of the research on hoarding is from the Western countries. This study aimed to provide data on the prevalence and correlates of clinically significant hoarding in a large sample of patients with OCD from the Indian subcontinent. METHODS We examined 200 patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition OCD for clinically significant hoarding using the Saving Inventory-Revised, followed by a clinical interview. RESULTS Twenty patients (10%) had clinically significant hoarding. In all cases, hoarding did not appear to be related or secondary to other OCD symptoms. None of the cases consulted for their hoarding problems. Compared with nonhoarders, hoarders hailed exclusively from an urban background and had a significantly higher frequency of certain obsessions and compulsions, bipolar disorder, generalized anxiety disorder, cluster C personality disorders, and a higher number of lifetime suicidal attempts. They also had a more severe OCD along with poorer global functioning and somewhat poorer insight into obsessive-compulsive symptoms. CONCLUSIONS The results suggest that clinically significant hoarding is relatively prevalent in Indian patients with OCD and that it appears to be largely unrelated to the OCD phenotype. However, the presence of comorbid hoarding is associated with more severe OCD, high comorbidity, more suicidal attempts, and a lower level of functioning. The results contribute to the current nosologic debate around hoarding disorder and provide a unique transcultural perspective.

Response rate of lorazepam in catatonia: A developing country's perspective

BACKGROUND Catatonia is a syndrome characterized by concurrent motor, emotional, and behavioral symptoms. Short-term benzodiazepine administration and electroconvulsive therapy have proven to be safe and useful for treatment of this syndrome. AIMS This study aimed to explore the evidence of effectiveness of lorazepam as a first line treatment for catatonia in a tertiary psychiatry centre in India given the lack of facilities for ECT in primary care centers of developing countries. We examined the response rate of lorazepam in Catatonia. METHODOLOGY Clinical charts of 107 inpatients, admitted over a duration of two years, with a primary diagnosis of catatonia were examined for response with lorazepam trial. Trial was considered as having received 3-6 mg per day of lorazepam for at least 3 days. RESULTS Among the patients who were given lorazepam treatment, 32 out of 99 (32.3%) showed response (with complete resolution of catatonic symptoms). Improvement in catatonic symptoms was seen in 68 out of 99 (68.7%) patients. CONCLUSIONS Lorazepam is cost effective and could rapidly relieve catatonic signs, even without the use of ECT in a significant proportion of catatonic patients. Its early use can prevent disease progression and complications.

Obsessive-compulsive disorder with and without bipolar disorder.

Aim:  Bipolar disorder (BD) is often comorbid with obsessive–compulsive disorder (OCD). In this study, we compared clinical profile and course of subjects with a primary diagnosis of OCD with and without BD.
