Indian research on comorbidities

A review of Indian research on co-occurring cannabis use disorders& psychiatric disorders

BACKGROUND & OBJECTIVES

Cannabis is a widely used illicit drug and its use is often associated with co-occurring psychiatric disorders. This systematic review was aimed to provide information on the published Indian studies on co-occurring cannabis use disorders and psychiatric disorders.

METHODS

An electronic search of available Indian literature using relevant search terms was carried out in May 2015 and 52 articles in English language published from India were included in the current review.

RESULTS

Studies on cannabis and associated psychotic disorders (n=16) chiefly described acute episodes with predominant positive symptoms, following cannabis use. Some studies (n=6) observed an overall increased prevalence of all psychiatric disorders and symptoms owing to cannabis use, while others (n=14) elaborated on high rates of substance use in those with psychiatric disorders. The effect of cannabis use on cognitive function was the focus of some of the Indian studies (n=7). All these studies barring one had all male subjects, and a single study described the service delivery model for those with dual diagnosis disorders in India. Most of the research used cross-sectional observational design and focussed on treatment-seeking population.

INTERPRETATION & CONCLUSIONS

A review of Indian literature on cannabis use and its association with psychiatric disorders indicates a high co-prevalence of psychotic disorders, especially in vulnerable individuals as well as high rates of co-occurrence of other psychiatric comorbidities. However, there is limited focus on exploring the aetiological association between cannabis use and psychiatric disorders; understanding the neurobiology of this association and management-related issues.

Substance use among outdoor treatment-seeking patients with mental illness: A case-control study from a tertiary care hospital of northern India

BACKGROUND

Substance abuse and mental disorder often coexist and may cause several consequences in sociooccupational functioning and health care and management. Indian data are sparse in this area.

OBJECTIVES

The aim of the study was to examine the sociodemographic profile, pattern, and prevalence of alcohol and substance use among person suffering with mental illness and to compare with those without mental illness.

METHODS

A total of 80 treatment-seeking patients with mental illness and 80 nontreatment seeking healthy accompanying persons were assessed for current substance use. Mental illness was screened using Structured Clinical Interview for DSM-IV Axis I Disorders and the diagnosis was made as per DSM IV, semi-structured sociodemographic pro forma was also applied. The data collected were analyzed using the Chi-square and Student's t-test.

RESULTS

Substance use was found 2.5 times higher among cases (56.2%) than controls (22.5%). Substance-using participants comprised mainly males belonging to rural residence. The substance using cases were more unmarried, less educated, poorer economically, and more nuclear family structures that substance-using controls. When compared with non-substance using cases, cases with substance use had more males than females and lower education. Although both groups were almost similar in term of marital status, family structure, residence, and socioeconomic status. Among both groups, most common substance use was tobacco, followed by alcohol and cannabis. Although all the substances were more prevalent among cases than controls. The prevalence of any substance use was highest among cases with psychotic disorder (77.3%), followed by unipolar depression (62.5%), bipolar affective disorder (41.7%), and anxiety disorders (21.4%). Tobacco and cannabis use was most prevalent among cases suffering with psychotic disorders, whereas alcohol use was most prevalent among cases suffering with unipolar depression.

CONCLUSIONS

Mentally ill individuals are vulnerable to develop substance use, thus they are doubly jeopardized. The susceptibility of these individuals stem from lesser insight, need for stimulation, to decrease the anhedonia induced by psychoactive medicines and poor awareness hence this group of individuals has several health and social consequences; therefore, they require due attention. A better care, support, and education are needed for substance using patients with mental illness to improve their prognosis and also help in their appropriate rehabilitation.

A Review of Indian Research on Co-occurring Psychiatric Disorders and Alcohol use Disorders

Excessive use of alcohol has been identified as a major contributor to the global burden of disease. Excessive use of alcohol is a component cause of more than 200 disease and injury conditions. Alcohol use has been associated with increased morbidity and mortality across all regions of the world including South-East Asia. Epidemiological as well as clinic-based studies from Western countries have reported a high prevalence of co-occurrence of alcohol use disorder and psychiatric disorders. The research has established the clinical relevance of this comorbidity as it is often associated with poor treatment outcome, severe illness course, and high service utilization. Understandably, dual disorders in from of alcohol use disorders and psychiatric disorders present diagnostic and management challenge. The current article is aimed to review systematically the published Indian literature on comorbid alcohol use disorders and psychiatric disorders.

Impact of co-morbid attention-deficit/hyperactivity disorder on self-perceived health-related quality-of-life of children with specific learning disability

BACKGROUND

About 12-24% of children with specific learning disability (SpLD) have co-occurring attention-deficit/hyperactivity disorder (ADHD). According to "parent-proxy reports", co-occurring "untreated" ADHD adversely impacts the health-related quality of life (HRQoL) of children with newly diagnosed SpLD, especially in their psychosocial functioning.

AIMS

To analyze the impact of "untreated" co-occurring ADHD on the "self-perceived" HRQoL of children with "newly diagnosed" SpLD.

SETTING AND DESIGN

Cross-sectional questionnaire-based study in a learning disability clinic situated in a medical college.

MATERIALS AND METHODS

From February 2008 to December 2008, 136 consecutive children newly diagnosed as having "SpLD with co-occurring ADHD (SpLD/ADHD)" or "SpLD only" were enrolled. The DISABKIDS chronic generic module (DCGM-37-S (V31)) instrument was used to measure their HRQoL. DCGM-37-S (V31) mean facet and total scores were computed for "SpLD/ADHD" and "SpLD only" children groups and compared using independent samples t-test.

RESULTS

HRQoL of "SpLD/ADHD" children was significantly better in limitation facet (mean difference: 8.20; 95% confidence interval (CI): 1.75-15.29; P=0.024). Although not statistically significant, the HRQoL of "SpLD/ADHD" children was better in independence, emotion, social inclusion and social exclusion facets; and in total score.

CONCLUSIONS

"SpLD/ADHD" children perceive their physical functioning to be significantly better. Also their perceptions of their psychosocial functioning are better. Contrary to parent-proxy reports, co-occurring "untreated" ADHD does not adversely impact the self-perceived HRQoL of children with "newly diagnosed" SpLD.
