The Paced Auditory Serial Addition Test (PASAT) measures the cognitive function that specifically assesses auditory information processing speed and flexibility, as well as calculation ability of a patient. It is the third component of the Multiple Sclerosis Functional Composite (MSFC), a series of three tests to document the course of Multiple Sclerosis.

**Purpose.** To record the measurements recorded during a Paced Auditory Serial Addition Test, normally as part of the Multiple Sclerosis Functional Composite suite of tests.
