Comorbidities are seen with obsessive-compulsive disorder (OCD) across the lifespan. Neurodevelopmental comorbidities are common in young children, followed by mood, anxiety, and obsessive-compulsive related disorders (OCRDs) in children, adolescents and adults, and neurological and degenerative disorders in the elderly. Understanding comorbidity prevalence and patterns has clinical and research implications. We conducted a systematic review and meta-analysis on comorbidities in OCD across the lifespan, with the objective to, first, estimate age-wise pattern and prevalence of comorbidities with OCD and, second, to examine associations of demographic (age at assessment, gender distribution) and clinical characteristics (age of onset, illness severity) with comorbidities. Four electronic databases (PubMed, EMBASE, SCOPUS, and PsycINFO) were searched using predefined search terms for articles published between 1979 and 2020. Eligible studies, across age, reported original findings on comorbidities and had an OCD sample size of ≥100. We excluded studies that did not use standardised diagnostic assessments, or that excluded patients on the basis of comorbidity. We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The review protocol has been registered on the International Prospective Register of Systematic Reviews. A comorbidity rate of 69% was found in a pooled sample of more than 15,000 individuals. Mood disorders (major depressive disorder), anxiety disorders (generalised anxiety disorder), neurodevelopmental disorders (NDDs) and OCRDs were the commonest comorbidities. Anxiety disorders prevailed in children, mood disorders in adults, whereas NDDs were similarly prevalent. Higher comorbidity with any psychiatric illness, NDDs, and severe mental disorders was seen in males, vs. females. Illness severity was inversely associated with rates for panic disorder, tic disorders, OCRDs, obsessive compulsive personality disorder, and anorexia nervosa. This systematic review and meta-analysis provides base rates for comorbidities in OCD across the lifespan. This has implications for comprehensive clinical evaluation and management planning. The high variability in comorbidity rates suggests the need for quality, multi-centric, large studies, using prospective designs.Systematic Review Registration: Unique Identifier: CRD42020215904.

In this position statement, developed by The International College of Obsessive-Compulsive Spectrum Disorders, a group of international experts responds to recent developments in the evidence-based management of obsessive-compulsive disorder (OCD). The article presents those selected therapeutic advances judged to be of utmost relevance to the treatment of OCD, based on new and emerging evidence from clinical and translational science. Areas covered include refinement in the methods of clinical assessment, the importance of early intervention based on new staging models and the need to provide sustained well-being involving effective relapse prevention. The relative benefits of psychological, pharmacological and somatic treatments are reviewed and novel treatment strategies for difficult to treat OCD, including neurostimulation, as well as new areas for research such as problematic internet use, novel digital interventions, immunological therapies, pharmacogenetics and novel forms of psychotherapy are discussed., International Clinical Psychopharmacology, 35 (4), ISSN:0268-1315, ISSN:1473-5857

AimsPharmacological management of Obsessive-Compulsive Disorder (OCD) presents a challenge in modern psychiatry. While most patients respond preferably to serotonin re-uptake inhibitors (SRI), the response is usually delayed by several weeks leading to an insufficient short term management of anxiety. It is also frequently inadequate and needs higher doses and augmentation in many instances. Investigating newer pharmacological strategies to address such treatment gaps has always been of interest. Buspirone is a novel anxiolytic medication with additional weak antidepressant and poor anti-psychotic effects. It is the only medication in its category, i.e. azapriones. It has comparable anti-anxiety efficacy to that of benzodiazepines without their sedating or habit forming effects, and has been demonstrated to moderate serotonin and other monoamine neurotransmission with a favourable safety profile.MethodWe reviewed the literature pertaining to the use of Buspirone in OCD for both as a primary anti-obsessive agent and for a potential secondary role in management of chronic anxiety and/or anxiety disorders comorbid to OCD.ResultThe results of a number of case reports and open trials have been positive while controlled trials have shown contradictory results. In a double blind RCT comparing clomipramine and buspirone, significant improvement was found in both groups with no differences between the two. Further two trials observing buspirone augmentation of clomipramine and fluoxetine treatment respectively, in a double-blind placebo controlled design reported significant improvement in the treatment as opposed to the placebo arm. Another double-blind placebo controlled study of buspirone augmentation of fluvoxamine resistant patients did not show significant benefits as an anti-obsessional agent, but notable anxiolytic effects were reported. In all the trials buspirone was largely well tolerated and did not pose any significant interactions with other psychotropic agents or dependence potential.ConclusionBuspirone is a pharmacologically unique agent with a good safety profile. Given the robust anxiolytic effects of this Peron along with complex neurotransmission modulatory effects coupled with a favourable tolerance and dependents profile might make buspirone an attractive novel pharmacological agent for augmentation in OCD . Further controlled studies to better establish effectiveness and deciphering if certain patients may respond to its use over others, are warranted

AimsOCD is a chronic and debilitating psychiatric illness. Current first-line treatments include serotonin reuptake inhibitors and cognitive behavioural therapy, but a substantial minority of patients fail to respond adequately, requiring further forms of intervention usually provided in a sequenced algorithm. Repetitive Transcranial Magnetic Stimulation (rTMS) uses magnetic pulses passed through a coil placed on the scalp to stimulate the underlying brain region. Clinical trials of r-TMS in OCD have produced conflicting results, possibly related to the variability in the site of stimulation, protocols used, and variability in the selection of patients. We perform an updated systematic review and meta-analysis of the effectiveness of rTMS for the treatment of OCD aimed to determine whether certain rTMS parameters (i.e. site, duration, protocol etc.) or patients’ characteristics (i.e age, duration of illness, illness severity, treatment resistance etc), are associated with effectiveness. Our overarching aim is to determine the place of rTMS in the sequenced OCD care-pathway.MethodThe meta-analysis is pre-registered in PROSPERO (ID: 241381). Potentially relevant studies will be retrieved using the MEDLINE, PsycINFO, and Cochrane Library databases using the parameters [‘obsessive compulsive disorder’ or ‘OCD’ or ‘obsessions’ or ‘compulsions’] AND [‘transcranial magnetic stimulation’ or ‘TMS’]. The reference lists of retained articles will also be scrutinized for additional relevant publications. Only full text English language articles will be included in the review. The methodological quality of the studies will be assessed using CONSORT criteria. A summary of the study's quality as a randomized clinical trial will be produced.ResultOur preliminary analysis shows some efficacy for r-TMS in non-treatment resistant OCD than treatment resistant OCD. Detailed results will be presented in the poster at the event. Effect measure will be either categorical (e.g. relative risk (RR) or odds ratio (OR) or continuous (mean difference or standardized mean difference - Hedge's g or Cohen's d - when taking into consideration the severity of the disorder as a dimension). These outcomes will be measured through validated instruments, in the form of both self- rated scales and observer rated scales including semi-structured interviews.ConclusionThis meta-analysis will identify the patient, illness and protocol parameters that determine clinical outcomes, as guide to optimizing the role of rTMS in the care of patients with OCD.

Modern medicine, with all its scientific and technological advancements overshadowing the humanistic components, has time and again found to be falling short of the expectations of clients and service providers alike. Person Centered Integrated Care has been rapidly gaining momentum as the reply to the current shortcomings of health care delivery and has consistently been ranked as desirable. The need of the hour is to take coordinated and consolidated steps in this direction. This requires research, changes in the education and training system of the physicians and integration of service delivery. The present article discusses these avenues and outlines international efforts in this direction, with a special focus on mental health care.

Charles Bonnet Syndrome (CBS) typically occurs in elderly people with peripheral vision impairment, or interruptions in the connections from eyes to visual cortex. The heterogeneity of presentations and causal mechanisms warrants clinical caution. In this report, we describe a case of CBS developing in the form of Lilliputian Hallucinations in an elderly gentleman, on the background of cataract and normal pressure hydrocephalus, the complexities arising out of such aetiogenesis, and its management. We emphasize upon the fact that CBS might develop through two concurrent mechanisms in a given individual. Treating one of these would mean persistent symptoms, and failing to recognize these would lead to continued morbidity.

Hunter syndrome is a rare X-linked recessive disorder caused by deficiency of the lysosomal enzyme iduronate-2-sulphatase, leading to progressive accumulation of a substance called glycosaminoglycans in nearly all cell types, tissues, and organs. Hunter syndrome presents with facial dysmorphism, airway diseases, skeletal defects, cardiomyopathies, and neuropsychiatric manifestations. Mental subnormality is a cardinal feature in Hunter syndrome. This is a progressive cognitive decline that is not amenable to enzyme replacement therapy. Due to progressive cognitive decline, training the children to improve the adaptive functioning is a challenge that creates immense stress for the caregivers. Patients with Hunter syndrome should undergo serial assessment of intellectual ability and may be trained accordingly.

Introduction: The current epidemiological data and meta-analyses indicate a bidirectional association between depression and metabolic syndrome (MetS). Aims: To assess the prevalence of metabolic syndrome and obesity in drug naive patients (in current episode) having Recurrent Major Depressive Disorder and Bipolar Depression. Method: This was a single point cross sectional observational study that involved administration of diagnostic and assessment tools and blood investigations. Recruitment for the study was done from a period of September 2008 to august 2009. Results: The prevalence of MetS was significantly more in the depression group when compared to healthy controls. The Bipolar depression group had 24% prevalence and recurrent depression group had 26% prevalence as opposed to none in the control group. The prevalence of MetS did not differ significantly amongst the both depression groups. Presence of central obesity was significantly more in the recurrent depression (30%) and Bipolar depression (24%) as compared to controls (8%). There was no statistically significant difference between the two depression subgroups. Discussion: Our study adds to the mounting evidence that links the presence of depression and metabolic syndrome. As we had ensured a drug free period of at least 3 months, the findings in our study indicate that the metabolic syndrome observed in our study is independent of drug exposure. Conclusions: This study demonstrated significantly more incidence of metabolic syndrome and central obesity in patients of depression than age and sex matched controls.

Olfactory dysfunctions are reported in multiple psychiatric disorders, including schizophrenia. The patterns of olfactory distortion in schizophrenia include impairments in olfactory perception, olfactory discrimination, olfactory memory, and olfactory perception threshold sensitivity. Olfactory dysfunction is believed to be an early warning sign of schizophrenia and is an important endophenotypic marker. We highlight a case of late onset acute and transient psychotic disorder with olfactory hallucination. Different implications of olfactory hallucinations in a psychotic patient are discussed with a review of the literature.

Cholinesterase inhibitors are effective pharmacological modality of treatment in patients with Alzheimer's disease. Urinary incontinence is a relatively uncommon side effect of cholinesterase inhibitors. It is difficult to differentiate the incontinence as a result of progression of the neurodegenerative process of dementia or due to medications or due to underlying local pathology (age-related). It seems illogical to recommend anticholinergics, which are commonly recommended for treatment of urinary incontinence, in patients with dementia who have already acetylcholine-deprived brain. We here discuss the management dilemma of urinary incontinence in a patient with Alzheimer's disease with review of literature.
