玛丽·达沃伦博士的法庭证词表明，帕特里克·麦克唐纳的心理健康问题源于药物滥用，而不是精神分裂症，这改变了他谋杀案审判的焦点。 Dr. Mary Davoren's court testimony suggests that Patrick McDonagh's mental health issues stem from substance misuse instead of schizophrenia, changing the focus of his murder trial.

据法医精神病学顾问称，一名被指控用砍刀谋杀邻居的男子面临的心理健康问题更多地与药物滥用有关，而不是精神分裂症。 A man accused of murdering his neighbor with a machete reportedly faces mental health difficulties more in line with substance misuse than schizophrenia, according to a consultant forensic psychiatrist. 帕特里克·麦克唐纳不承认谋杀罪，但承认过失杀人罪。 Patrick McDonagh has pleaded not guilty to murder but guilty to manslaughter. 他的案件与帕特里夏·凯西教授的案件不同，帕特里夏·凯西教授声称，由于精神分裂症引起的急性精神病症状，麦克唐纳对杀人的责任大大减轻。 His case differs from that of Professor Patricia Casey, who claimed that McDonagh's responsibility for the killing was substantially reduced due to acute symptoms of psychosis due to schizophrenia.
