    BACKGROUND: Little is known about the effects of depression on the mortality rates of elderly subjects with dementia.

    BACKGROUND: A persistent course of depression has been described in subjects with and without dementia. Up to the present it is unclear to what extent dementia affects the prognosis of depression.

    RESULTS: Adjusting for demographic characteristics and physical health, dementia was not associated with the ...

    A group of 14 patients with isolated visual hallucinations who met the criteria proposed by Gold and Rabins for Charles Bonnet syndrome (with the exception of the criterion "hallucinations are stereotyped") underwent psychiatric, neurologic, and ophthalmologic tests. Additional common characteristics of the hallucinations included the absence of personal meaning of the content of the hallucinations and the disappearance of the hallucinations when the patients closed their eyes. There was ...
