| Outline of Final Research Achievements |
Severe methylmercury poisoning occurred in Minamata and neighboring communities in Japan during the 1950s and 1960s. A considerable number of children were born with conditions resembling cerebral palsy, later known as congenital Minamata disease. Although surviving patients are now in their 50s or 60s, few assessments of functional capacities in daily living have been performed. Moreover, possible impacts of methylmercury exposure in utero among residents, which is likely lower levels than in congenital Minamata disease patients, are rarely explored. The present study indicates that the Activities of Daily Living status of congenital Minamata disease patients, now in their 50s or 60s, has substantially declined during the last 10 years; a decline that was much steeper in comparison with expectation in subjects of similar ages. This study also suggests possible neurological and neurocognitive impacts of prenatal exposure to methylmercury among exposed residents of Minamata.
