Dementia diagnosis
There are many widely used sets of criteria for the diagnosis of dementia.
Recently a comparison of six commonly used classification systems including:-- DSM-III, ICD-10 & CAMDEX has been made.
The proportion of subjects with dementia varied from 3.1 percent with ICD-10 to 29.1 percent with DSM-III.
The six classification systems identified different groups of subjects as having dementia.
Many doctors may be astonished that out of the total of 1,879 cases only 20 of the cases were given a diagnosis of dementia according to all six systems.
These sets of criteria for the diagnosis of dementia differed by a factor of 10 in the number of cases classified as having dementia.
The features that most frequently caused disagreement in diagnosis were:--
- Long-term memory
- executive function
- Social activities
- Duration of symptoms
