forensic issues, particularly dangerousness. Dangerous patients suffe
ring from the Othello delusion may present with hostility ranging from
verbal threats to homicidal acts. We present three cases of individua
ls suffering from Othello syndrome associated with significant hostili
ty and organic mental factors. We analyze these cases along with Othel
lo syndrome cases culled from the recent anglophonic literature, espec
ially in terms of implications for domestic and public safety.
