Young-onset dementia, defined as dementia occurring under the age of 65, is an increasingly recognized cause of morbidity and disability. There are few reports of the clinical profile of young-onset dementia from India. The objective of this study was to determine the clinical profile of patients attending a specialist cognitive disorders clinic in West Bengal, an eastern state of India. Almost one-fourth (94/379, 24.5%) of all the patients with dementia were of young onset. Women constituted about one-third of these cases. There was a gradual increase in the number of cases with rising age. The most common etiologies were Alzheimer disease (33%), frontotemporal dementia (27%), and vascular dementia (20%). In contrast to other published studies of young-onset dementia, frontotemporal dementia was commoner than vascular dementia. This could be due to referral bias. A positive family history was found in close to one-fifth of the patients. Close to 10% of the patients had reversible causes of dementia. Community based study is required to confirm the findings of this study.

Epilepsy is a major health problem in India, but community based incidence study is rare. This study was undertaken to determine the incidence rate in a rural community of the state of West Bengal, India. The study was done through house to house survey by a dedicated team of neurologists, who carried out the survey cum case detection over 5 years. A total of 38 cases were detected during the survey period in a population of 20,966. The age adjusted (to World Standard Population) average annual incidence rate was 42.08 per 100,000 persons per year (95% confidence interval, 29.75-57.86). This rate was higher than many developed countries, but lower than the developing countries. Cerebral infection was the most common putative factor observed. An increasing trend of incidence of epilepsy has been observed over the years during the period of the study.
