Psychostimulants, adult attention deficit hyperactivity disorder and morbid jealousy

Objective: This paper aims to discuss the relationship between morbid jealo usy, stalking behaviour, and psychodynamic issues. Comment will be made on the risk associated with diagnosis of adult attention deficit hyperactivity disorder (ADHD) and use of psychostimulants. Clinical picture: A man born in the former Yugoslavia charged with stalking was referred for assessment. He presented with a history of treatment for ADHD with dex-amphetamine and delusions regarding his wife's fidelity. Treatment: The patient was treated with neuroleptics and counselling for hi mself and his family. Outcome: The patient was returned to the community. He separated from his w ife but retains the abnormal belief. Conclusions: The diagnosis of adult ADHD appears to be increasing in Wester n Australia. Treatment with stimulants is common. The misdiagnosis of ADHD and consequent misuse of stimulants, can lead to the development of morbid jealousy, stalking behaviour and arrest.
