This article presents 2 cases where patients with Alzheimer’s Disease (AD) committed suicide (methods: physician assistance & self-inflicted gunshot wound). The cases show that suicidal ideation in patients with preserved insight, who perceive they are not responding to pharmacological treatment, must be taken seriously even when depression & other suicide risk factors are absent. The article notes that the impaired insight common to most AD patients may be protective against suicide. (21 Refs.)
