Many people with MS believe that they do not think as clearly or as quickly as they have in the past. Sometimes, like for older people, this perception is simply the result of changing expectations of themselves. Since MS has a reputation for disturbing brain functioning, it is easy to blame it for momentary lapses that may be more accurately attributed to distraction, inattention or normal forgetfulness. When there is a question about such cognitive changes, neuropsychological testing is sometimes recommended.
Neuropsychological testing is a subcategory of psychological testing in general.
Most people have had some form of psychological testing. These tests are very popular and have proliferated. Among these are a large number of tests that were constructed in order to measure cognitive difficulties - trouble with the speed, accuracy, and complexity of thought. These have been called neuropsychological tests. Unlike in some areas of measurement, there is not a single neuropsychological test that measures everything that the brain does.
