The cognitive tests are tests to evaluate functions such as attention, memory, visual-spatial skills, language, intelligence, etc, in order to diagnose cognitive deficits.

Their usefulness can be found both in the clinical setting (assessment of cognitive function in people with brain injuries and neurological diseases), as in forensics (expertise in civil, criminal, insurance, pension).

The cognitive tests allow the detection of neuropsychological deficits, which are beyond the neuroradiological imaging techniques (eg. TAC, RMN).
