Background:Knowledge of the prevalence of mental disorders is essential for setting up services and allocation of resources. Existing studies suffer from methodological problems which limit their utility and generalizability. There was a long felt need to conduct a scientifically robust study in different regions of India to have national prevalence rates.Aims:This study aims to estimate the prevalence of mental disorders in a representative population of Punjab as a part of the National Mental Health Survey.Settings and Design:Community-based survey carried out in rural and urban areas of Punjab using multistage, stratified, random cluster sampling technique and random selection was based on Probability Proportion to Size.Materials and Methods:The survey was conducted in 60 clusters of 4 districts (Faridkot, Ludhiana, Moga, and Patiala) of Punjab. Mini-International Neuropsychiatric Interview adult version 6.0 for mental morbidity, case definition for generalized tonic–clonic seizure, an expansion of the Fagerström Nicotine Dependence Scale for tobacco use and screener for intellectual disability were used. Appropriate statistical methods were applied.Results:A total of 2895 respondents aged >18 years from 719 households were interviewed. The prevalence of lifetime and current mental morbidity was 17.94% and 13.42%, respectively. Higher prevalence of mental morbidity was found among persons aged >60 years and those belonging to lower income group and rural population.Conclusions:The prevalence of mental morbidity is high in the population. The findings give a clear picture of magnitude of the problem and will help policy planners to tackle the situation which looks grave and warrants immediate intervention.

BackgroundActive bilingualism provides cognitive reserve/resilience against age‐related neurodegenerative conditions like MCI and dementia. Evidences suggest that bilingualism delay the onset of MCI and dementia by preserving cognitive functioning for a longer period of time. India has a linguistically diverse population where bilingualism is a norm and its effects on cognitive reserve are devoid of immigration, education and socioeconomic status. We conducted a door‐to‐doorcommunity‐based study to investigate the impact of bilingualism on the prevalence of dementia and MCI in healthy older monolingual and bilingual population. The study also examined the effect of bilingualism on cognitive performance.MethodA total of 1145 older adults (366 monolinguals and 779 bilinguals) were recruited. The cognitive functions of elderly persons of ≥ 60 years old residing in urban Bengaluru, India were assessed using Clinical Dementia Rating Scale (CDR), Addenbrooke’s Cognitive Examination (ACE‐III), TNI, Verbal Learning Test (VLT), and Instrumental Activities of Daily Living‐Elderly (IADL‐E). The Language Use Questionnaire (LUQ) scores were used to categorize speakers into monolinguals and bilinguals. Based on the neurologic, neuropsychological, and functional data, participants were classified into 3 categories: normal cognitive functioning, MCI (based on Petersen’s criteria), and dementia (based on DSM‐IV criteria).ResultThere was a significant difference in the proportion of MCI and dementia patients between monolingual (2.10 % dementia and 7.14 % MCI) and bilingual (0.40 % dementia and 4.64 % MCI) elderly (p < 0.001) (Table 1). Healthy elderly bilinguals performed significantly better on global cognition and delayed verbal recall than monolinguals independent of the effects of age, education and gender (Table 2).ConclusionThe findings of this large door‐to‐door community study reveals the protective role of bilingualism in developing cognitive impairment due to MCI and dementia. Furthermore, the study demonstrates the effect of bilingualism as a measure of cognitive reserve/resilience through better cognitive status and episodic memory in older people from a socio‐culturally and linguistically diverse population.
