Question:
One is an army major and the other is a Cyprus resident. Lot of things can happen after a head injury while the brain tries to recover and goes into an overactive state and remain in that state for months. Were those people had any co-morbid condition in addition to stealing such as hyperactivity etc? Also, were they on medication and what type? I don't see any co-relation between kleptomania and head injury. There is a connection to psychopathy and head injury. However putting the Kleptomaniacs also in the psycopathic category may be considered misdiagnosis.

Answer: The observation that collecting behaviour can assume pathological proportions in patients with certain patterns of brain damage led us to hypothesize that dysfunction in a system encompassing mesial prefrontal cortices accounts for abnormal collecting and may guide normal collecting. We tested the hypothesis in 86 subjects with focal lesions of the telencephalon, by relating the neuroanatomical placement of the lesions to the presence of repetitive and indiscriminate acquisition behaviour and impaired discard behaviour. The subjects had no history of psychiatric disease or abnormal collecting behaviour prior to lesion onset. Lesions were analysed with high-resolution three-dimensional MRI. Collecting behaviour was evaluated with a standardized questionnaire completed by a close relative of each subject. Thirteen subjects exhibited abnormal collecting, characterized by massive and disruptive accumulation of useless objects. In all cases, the abnormality of collecting behaviour was severe and persisted despite attempted interventions and obvious negative consequences. There were no differences between pathological collectors and non-collectors on tests of executive functions or anterograde memory.
