The anti-social behaviour resulting from hypoglycaemia can take many forms – the two most common and publicly important are violence against individuals and driving whilst impaired. The legal implications may, however, be different depending on the cause.

Its ability to turn a normally caring, docile and socially responsible individual into an aggressive, socially irresponsible one 4, 5 is a well recognised though fortunately uncommon complication of hypoglycaemia. The fact that hypoglycaemia affects cognitive more than motor functions of the brain has been exploited in the courts throughout the world. I have drawn heavily on person experience by providing examples of where hypoglycaemia has figured largely or predominantly in deciding the outcome of a criminal or civil case in the UK. In this paper I shall deal briefly with each of these aspects of hypoglycaemia and refer the interested reader to more detailed studies where they exist. 2, 3 It may be invoked as a defence against a criminal charge or a civil action or offered in mitigation of a crime – in other words the perpetrator knew that what he/she was doing was wrong but was mentally impaired – though not to such an extent that he was a ‘non-person’ or automaton.
