Background:Depression is a common neuro-psychiatric consequence of stroke, affecting approximately 40% of the patients. Many studies show that in addition to the psychosocial stress, neurobiological factors such as site of infarct and brain atrophy may also be related to Post Stroke Depression (PSD). There are conflicting results in this area of research and paucity of such data in Indian literature. Thus the aim of this study is to weigh the importance of lesion location in PSD.Materials and Methods:Sixty two subjects with their first ever stroke were interviewed using a semi-structured proforma and PSD diagnosed using MINI Plus interview. Scales of Beck Depression Inventory and Montgomery Asberg Depression Rating Scale were used to assess severity of depression. Mini mental state examination was used to assess cognitive impairment and Barthel Index to measure Activities of Daily Living. Neuro-imaging provided information on site and side of lesion. Collected data was analysed using SPSS version 15.0.Results:PSD was diagnosed in 28 subjects, amongst who 19 had left sided lesions. Left sided cortical infarcts and sub cortical infarcts showed statistically significant association with PSD.Conclusion:Results are in keeping with previous landmark studies. Differences in emotional reactions depending on hemisphere and site of the infarct as shown in this study suggest organic biological basis for post stroke depression. Understanding the etiological basis would allow clinicians to monitor patients at risk of developing PSD, enabling early detection and treatment thus improving their quality of life and rehabilitation.

SOC-13 was found to be a reliable and valid instrument for measuring SOC in an Indian context. The present study contributes to health promotion in an Indian context, and could be useful even in other developing countries and for further research in India.

Informal caregivers are unpaid individuals who help friends or family members who cannot fully care for themselves. However fulfilling the act of helping debilitated individuals, exposure to another person's traumatic experiences often results in psychological distress. Caregiver's stigma towards HIV worsens this. Hence, this study aims to assess the effect of stigma on the mental health of caregivers so that their needs for support can be determined. A cross sectional hospital based study was carried out in Mangalore, India on 150 informal caregivers of PLHIV. The HIV Stigma Scale was used to assess stigma and DASS-21 was used to assess depression, anxiety and stress. Of the 150 caregivers, 20% marked one or more items on the stigma scale. Frequency of depression, anxiety and stress was 46%, 27% and 8% respectively. Most caregivers who had stigma and anxiety were of those patients diagnosed for a shorter duration of time (≤5 years) n = 20, p = 0.05 and n = 26, p = 0.03 respectively. Spouses of PLHIV (n = 31, p = 0.005), sero-positive caregivers (n = 25, p = 0.03) and those living with patients (n = 39, p = 0.01) suffered most from anxiety. Stress was significantly associated with depression (83%, p = 0.007) and anxiety (66.6%, p = 0.001) in caregivers. In conclusion, more of depression and anxiety was observed among the participants than stress. Stigma was seen in 20% of the participants. Stigma was not significantly associated with depression anxiety and stress.

Context:Adolescence is a period of turmoil, leading to several mental health challenges including anxiety and/or depression.Aims:To study the prevalence of depression and anxiety among higher school going adolescents and their sociodemographic correlates.Settings and Design:This cross-sectional study included 201 schoolgoing adolescents.Subjects and Methods:Depression and anxiety were measured using Beck Depression Inventory and Screen for Child Anxiety Related Disorders.Statistical Analysis Used:Chi-square test and binary logistic Regression with Hosmer–Lemeshow goodness-of-fit model.Results:Overall, 82 (40.8%) showed depression (from mild mood disturbance to severe and extreme depression). Among females, it was 49.3% (vs. 35.9% among males, odds ratio [OR] 2.00; 95% confidence interval [CI]: 1.02–03.97, P = 0.046). Overall, 110 (54.7%) participants had one or the other type of anxiety. Depression among the participants having one or other type of anxiety was 60% (vs. 17.6% without anxiety, OR 7.34; 95% CI: 3.68–14.64, P < 0.0001).Conclusions:Depression and anxiety were high among the study participants. Co-existing anxiety and female gender are significantly associated with depression among them. Increasing age, socioeconomic factors, and parental education are other factors influencing depression and anxiety but were statistically not significant.

Among the many factors responsible for the cognitive decline in Alzheimer’s disease, beta amyloid protein and plaque formation is crucial. This amyloid pathology is associated with activation of glial cells and oxidative stress but whether oxidative stress activates beta amyloid protein in the neurons is not clear. Further the expression of microglia is also known to vary during pathogenesis of beta amyloid plaques. The aim of the present study is to evaluate the antioxidant effect of NAC on amyloid pathology and cognition and also to investigate the link between amyloid pathology and glial cells activation. Intracerebroventricular colchicine in rats known mimics human AD in many aspects including memory loss, oxidative stress, and hyper phosphorylation of tau protein. The animal groups consisted of age matched control, sham operated, AD, and NAC treated in AD models of rats. Cognitive function was evaluated in active avoidance test; beta amyloid protein, beta amyloid plaques, astrocytes, and microglia cells were quantified using immunohistochemistry in hippocampal and prefrontal cortices. Colchicine has resulted in significant cognitive loss, increased intraneuronal beta amyloid protein expression, increased reactive astrocytes, and activated microglia in all the regions of the hippocampus and prefrontal cortices. The antioxidant NAC has reversed the cognitive deficits and inhibited microglia activation but failed to inhibit BAP expression and astrocytosis. Intraneuronal BAP accumulation is deleterious and known to adversely affect cognition, but in this study in spite of intraneuronal BAP accumulation, the cognition is restored. It can be postulated that NAC might have reversed the effect of intraneuronal beta amyloid protein by acting on some downstream compensatory mechanisms which needs to be explored.
