Key result
The CAMCOG cut-off of 60/61 was more effective in detecting dementia with 100% sensitivity and 97% specificity compared to the MMSE cut-off of 21/22 with 95% sensitivity and 86% specificity.

Does CAMCOG improve the detection of dementia compared to MMSE in elderly general hospital inpatients?
CAMCOG is more effective than MMSE in detecting dementia among elderly general hospital inpatients, though the optimal cut-off may be lower than previously suggested.
Supports CAMCOG over MMSE for dementia detection in elderly inpatients; hypothesis-generating and requires prospective validation before practice change.
One hundred and eight patients aged 70 and older randomly chosen from those admitted to the departments of medicine and surgery in a university hospital were examined for dementia by the Cambridge Mental Disorders of the Elderly Examination (CAMDEX) and DSM‐III‐R criteria. Cognitive impairment was assessed by the cognitive section of the CAMDEX (CAMCOG) and the Mini‐Mental State Examination (MMSE). Fifty‐one per cent of the sample met DSM‐III‐R criteria for at least one psychiatric disorder, dementia being the most common (35%). The cut‐off point of CAMCOG (60/61) was more effective (100% sensitivity and 97% specificity) than the cut‐off point of MMSE (21/22) (95% sensitivity and 86% specificity) in detecting dementia, although the optimal cut‐off point of CAMCOG for our sample was lower than that suggested in previous studies.

Lázaro et al. (1995) conducted a cross-sectional in Dementia (n=108). CAMCOG (cognitive section of CAMDEX) vs. Mini-Mental State Examination (MMSE) was evaluated on Detection of dementia. The CAMCOG cut-off of 60/61 was more effective in detecting dementia with 100% sensitivity and 97% specificity compared to the MMSE cut-off of 21/22 with 95% sensitivity and 86% specificity.
