| Annotation | Charles Bonnet Syndrome (CBS) is a condition involving the onset of complex and vivid visual hallucinations in the absence of medical illness or intellectual impairment. The neuropsychological function of 15 older adults with presenting complaints of visual hallucinations who met criteria for CBS were compared with 11 demographically matched controls to determine if there was any evidence of functional brain impairment. CBS patients were screened for focal brain lesions and epileptic disturbances, and also received pattern visual evoked potentials and ophthalmological examinations. Score from the Wechsler Adult Intelligence Scale (revised), Mattis Dementia Rating Scale, Wechsler Memory Scale and the Auditory Verbal Learning Test were compared. Significant differences were found between the two groups on neuropsychological measures. 14 of 14 had ocular abnormalities; and 6 of 8 had abnormal age-corrected pattern visual evoked potentials indicative of dysfunction in the visual system. Results indicate that patients diagnosed with CBS or isolated visual hallucinations provide evidence of neuropsychological changes commonly associated with early stages of dementia. (RH). |
