Use of Clock Drawing Test as a Screening Tool for Cognitive Status Evaluation in Middle-Aged Patients with Depressive Disorder

Abstract

Conclusion: The cognitive functions of middle-aged patients with depressive disorder could be screened by the CDT. The fact that the CDT is sensitive enough to detect the cognitive impairment inherent in depressive disorder, as well as being correlated with symptom severity, makes this test useful in the assessment of cognitive status in depression (Shulman method; r=0.26, p<0.05).
