Document Summary
Clinical utility of biological assessment measures of brain structure and function. Velakoulis and lloyd described the utility of spect scanning in clients with neuropsychiatric disorders involving early onset dementia. Spect scans had to be interpreted within the context of other information because the scans reveal abnormalities that are common across various neurological conditions (i. e. they are non- speci c) Test of the clinical utility of these measures is the extent to which the information gleaned actually changes diagnoses and makes them more accurate. Ct scan data had an in uence on diagnosis and treatment planning 10-15% of the cases. This study showed that magnetic resonance imaging (mri), along with the nal comprehensive clinical diagnosis of neuropsychology status, led to a change in the diagnosis of over one- quarter of the clients assessed. Reviewed mri studies of four childhood psychiatric disorders: adhd, depression, bipolar, schizophrenia.
