The occurrence of pallidal lesions with or without other hypoxic/ischaemic brain injuries was evaluated in 100 intravenous (i.v.) heroin addicts.
The brains were collected consecutively from forensic autopsies during the period from January 1995 to June 1996.
The autopsies were required by the police and performed at The Institute of Forensic Medicine, The National Hospital, Oslo.
There were 21 women and 79 men, median age 32 (range 21-47) and 34 (19-60) years, respectively.
Of 38 brains with abnormalities, twenty-five cases showed isolated or combined lesions of hypoxic/ischaemic origin.
Pallidal lesions were found in nine brains : six lesions were old, one was subacute (a couple of weeks), and two were part of recent, generalized hypoxia/ischaemia.
Six persons had old infarcts in the hippocampal formation, and one of them in combination with old pallidal infarcts.
In seven brains small and old infarcts were found in watershed areas in the cerebellum.
Between five and ten percent of i.v. heroin addicts might have pallidal infarcts, either as the sole lesion, or combined with other manifestations of hypoxic/ischaemic brain injury.
This might give severe mental disturbances in the affected persons.
