An Afghan man with mental health problems is chained in a mud room at the Mia Ali Baba shrine, in line with a traditional belief that spending 40 days chained in isolation at the shrine can cure the illness, in Jalalabad October 8, 2010. Afghanistan is struggling to fight the mental health problems that afflict an estimated two thirds of its population after decades of violence, the country's health ministry said on Sunday, World Mental Health Day.
