title: Myxoedematous madness and grievous bodily harm.
abstract: Psychosis is a rare but recognized complication of hypothyroidism (otherwise known as 'myxoedematous madness'). This is the report of a man charged with attempted murder who was found to be suffering from myxoedematous madness. The case illustrates several problems in the law relating to mental disorder and criminal responsibility. He was interviewed in the absence of an appropriate adult and this led to the inadmissibility of the police interviews. However, to have laid the basis for a defence of insanity the ideal evidence would have been what he told the investigating police officers about his state of mind at the material time, under caution and possibly with the assistance of an appropriate adult. As it was, although he was clearly mentally ill at the material time, the insanity defence was not open to him as he did not satisfy the MacNaughton Rules and his mental state did not fulfill the criteria for automatism. By the time he stood trial he was fully recovered from his psychosis and this faced the judge with a difficulty in sentencing him. The case is used to discuss proposed changes to the law concerning insanity.
