[Psychiatric symptoms among patients with dementia seen in an ambulatory service].
Subjects with dementia often display an array of neuropsychiatric symptoms that include disorders of mood, delusions, hallucinations, vegetative symptoms and psychomotor abnormalities. The present study was designed to investigate the prevalence of psychiatric morbidity amongst patients with the clinical diagnosis of dementia (ICD-10) assessed at a Memory Clinic in São Paulo-Brazil between February 1997 and May 1998. The mental and cognitive state of patients were assessed with an extended version of the SRQ-20 and the MMSE respectively. Thirty-four (45.3%) out of a total of 75 subjects scored 8 or more on the SRQ-20, indicating the presence of significant psychiatric morbidity. Depressive symptoms were reported by 69.3% of patients. Persecutory ideas and auditory hallucinations were observed in 20.0% and 16.0% of the sample respectively. Eight subjects (10.7%) described suicidal ideation--they all displayed depressive symptoms. Patients with scores on the SRQ-20 > or = 8 or who described suicidal ideation were significantly younger than their counterparts. Auditory hallucinations were more frequent amongst subjects with lower MMSE scores. There were no sex differences in the distribution of the psychiatric symptoms under investigation. The assessment of patients with dementia should always include a detailed psychiatric examination, as the detection and treatment of such symptoms may contribute to decrease the stress of patients and the burden on carers.
