Abstract

The result of neuropsychological tests is crucial to confirm a diagnosis of dementia or cognitive impairment. It might be improper judging individuals with different basic cognitive function using the same standard. The evaluation of premorbid intelligence is an effective way for error correction, but not enough attention has been paid during clinical practice.
