Healthcare
Mental illness is in most places treated separately from physical illness.  It was, and in some places still is, given a religious explanation.  People were sent to workhouses or asylums if they were thought to be dangerous to themselves or other people.  By the 19th century many of them were very large. There was very little involvement by doctors until  the 20th century when psychiatry developed. The classification of mental disorders has been, and still is, controversial.  Mental health services generally get less attention and money than those for physical illness. Abuse of patients is not uncommon.  People are often sent a long way from home. People may have to wait a lot longer for help in the community.
