Clock Drawing Test in a Space-Occupying Process

摘要

We read with great interest the article of van Mimster et al on a dural fistula presenting as a treatable cause of cognitive impairment. The authors demonstrated a markedly impaired clock drawing test (CDT) before treatment, which completely normalized after therapy. By presenting a case vignette, we wish to emphasize that an impaired CDT-especially in a younger individual-can be an alarming sign to prompt further examination.
