Pathological stealing is kleptomanic behavior due to brain disease. Like kleptomania, there is an inability to resist stealing unneeded objects of insignificant value.1 Kleptomania may be related to obsessive compulsive disorder (OCD) and could respond to selective serotonin receptor inhibitor (SSRI) medications, the treatment of choice for OCD.2,3 Herein, we report four frontotemporal dementia (FTD) patients with pathological stealing and their treatment with SSRI medications.
A 59 year-old woman had a two-year history of petty theft and a progressive personality change. She would go in stores and take items without concern for payment or witnesses. She made personal comments to strangers, had a decline in empathy and self-care, and developed compulsive behaviors and an addiction to ice cream. On examination, she had a memory deficit, poor naming, and executive dysfunction. Functional neuroimaging showed decreased perfusion in the frontal and anterior temporal lobes.
A 60-year-old man began entering his co-workers’ areas and stealing small items from their desks, shelves, or cabinets. He had a three year history of a progressive personality change characterized by decreased initiative, disinhibition, lack of empathy, compulsive behaviors including hoarding, indiscriminate eating, and decreased personal hygiene. On examination, he had impaired memory, decreased naming, and executive dysfunction. Functional neuroimaging showed prominent frontal hypometabolism.
A 58-year-old woman with a personality change was apprehended for stealing food in grocery stores and cafeterias. She had became disengaged from her prior activities and emotionally detached from her family. There were uncharacteristic incidents of disinhibited behavior where she passed gas in public or made off-color comments. She had repetitive behaviors and dietary changes. On examination, she had a memory retrieval deficit and executive dysfunction. Functional neuroimaging showed prominent frontal hypometabolism.
A 48 year-old man with a three-year history of a progressive personality change got into difficulty for stealing oranges from his neighbor’s trees. His personality change began with decreased completion of his work, decreased concern for his family, and inappropriate verbal commentary and touching of others. He became disheveled, developed compulsive hoarding, and had a food fad for ice cream. On examination, his language and executive functions were impaired. On functional neuroimaging, he had hypometabolism of the frontal lobes.
All four patients met criteria for FTD.4 They underwent six or more months of trials of sertraline (up to 200mg), fluoxetine (up to 60mg), and paroxetine (up to 60mg), without attenuation of their incidence of pathological stealing.
