Studies comparing the CDT with a neuropsychiatric battery for dementia.

Study	Scales	Population	Conclusion
Bourke et al. (1995)21	Shulman et al. (1993), Mendez et al. (1992)×CAMCOG and the pentagon drawing	AD (n=77)	Good reliability but with high false-negatives.
Heinik et al. (2002)47	Shulman et al. (1993), Freedman et al. (1994)×CAMCOG e MMSE	AD (n=49)	Good correlation between the CDT and the CAMCOG in mild AD. Poor correlation between Freedman and  MMSE and CAMCOG in CDR 2 patients
Heinik et al.(2003)48	Freedman et al. (1994)×CAMCOG and MMSE	Dementia (n=88) Depression and anxiety disorders (n=26)	Good correlation between the CDT, MMSE and the CAMCOGCDT plus MMSE were almost as good as the CAMCOG
Heinik et al. (2004)16	Shulman et al. (1993), Freedman et al. (1994), CAMCOG scale×CAMCOG and MMSE	AD (n=52)VD (n=36)Depression and anxiety disorders (n=26)	Good correlation between the CDT and the MMSE and CAMCOG.
Van der Burg et al. (2004)49	Shulman et al. (1993), CAMCOG scale×CAMDEX	Dementia (n=387)Controls (n=86)	Weak reliability with Shulman scale. Low specificity in both scales.

AD, Alzheimer's disease; CDT, Clock Drawing Test; MMSE, Mini-Mental State Examination.
