The Cognistat is designed to rapidly assess neurocognitive functioning in three general areas: level of consciousness, orientation, and attention span; and five major ability areas: language, constructional ability, memory, calculation skills, and reasoning/ judgment.

Features and benefits

  • Includes a detailed and expanded discussion of the importance of individual “trait” factors and situational-environmental “state” factors that can affect test performance.
  • Provides an outline of commonly used medications that have the potential to affect test performance and a survey of 12 medical factors that frequently invalidate test results.
  • Offers a clear and immediately understandable graphic profile of impairments.
  • Includes normative information for adolescent, adult, and geriatric populations.
  • Provides documentation of the Cognistat’s utility in patients with dementia, stroke, traumatic brain injury, substance abuse, and epilepsy, citing a number of new clinical and research articles.
