| Annotation | The Clock Drawing Interpretation Scale (CDIS) was used in this Israeli study, and compared a group of 21 older schizophrenic patients with a group of 21 Alzheimer's disease (AD) patients matched for gender, education and cognitive impairment. Schizophrenic patients were considerably younger than AD patients (63.5 versus 81.3 years), but similar concerning gender, education, MMSE and CAMCOG scores. CDIS scores were not correlated with age in either group. Inter-rater reliability was high (range 0.84-0.97). No significant differences between patient groups were found in mean CDIS total scores. A CDIS specific item analysis revealed that schizophrenic patients were less impaired than AD patients on three out 20 items: Number 7 (most symbols aligned in a clockwise and rightward direction); Number 8 (all symbols totally within a closure figure); and Number 13 (numbers do not go beyond 12). Although schizophrenic patients and AD patients had similar total scores on the clock drawing test, they differed on specific test items related to spatial planning deficit and perseveration. (RH). |
