Worldwide worry

Last year, Japanese police received about 130,000 reports on missing people who were suspected to have or had been diagnosed with dementia, broadcaster NHK reported in June this year.

The number of cases was up 7 percent year-on-year. Police later reported that nearly 400 of those missing were already dead.

There were about 1,000 more men than women reported missing. Most reports filed with the police were made in Osaka, the second-largest city in Japan.
