SUMMARY
1. The CDT provides a quick assessment of visuospatial and praxis abilities and may detect deficits in both attention and executive dysfunction (Adunsky et al. 2002; Suhr et al. 1998; McDowell & Newell 1996).
2. The CDT involves having the patient draw a clock, place the numbers on the clock in their proper positioning and then place the arms of the clock at a requested time.
3. The task itself is viewed as being highly complex, involving a number of neuropsychological abilities (Suhr et al. 1998).
4. Effective as a supplement to other cognitive assessments.
DISADVANTAGES
5. The CDT is negatively influenced by increasing age, reduced education and the presence of depression (Ruchinskas & Curyto 2003; Lorentz et al. 2002).
6. The CDT may also be affected by visual neglect, hemiparesis and motor incoordination (Ruchinskas & Curyto 2003).
