Chapter 3 goes back in time to cover the second half of the nineteenth century with regards to the issue of children’s insanity and mental suffering. The notion of the child mind and the debates surrounding its understanding and relation with the body are explored through a series of representative diseases, including ‘night terrors’, melancholia, hysteria and monomania. The limitations of the anatomo-clinical method are discussed in relation with the work of leading psychiatrists and neurologists, including James-Crichton Browne and Henry Maudsley.
