Cognistat and Cognistat Five are the preferred screening tools for health-care professionals who need an accurate and reliable cognitive assessment method to triage patients. The original Cognistat was designed to provide a rapid analysis of major cognitive impairments in medical and psychiatric settings, particularly in situations where patients are unable to cooperate with lengthy testing regimens. The test requires 15-20 minutes to administer.
Cognistat Five is a shortened version of the full length test designed to allow busy primary care physicians and other health-care professionals to rapidly screen for Delirium, Mild Cognitive Impairment (MCI) and Dementia – this version of the test takes approximately five minutes to administer.
Developed by Ralph J. Kiernan PhD, Jonathan Mueller MD and J. William Langston MD, Cognistat has been in use for over thirty years in a wide range of fields: Elder Care, Delirium, Mild Cognitive Impairment, Dementia, Alzheimer’s, Stroke, Rehabilitation, Substance Abuse and Trauma.
Cognistat’s development was based on the principle that cognitive functions are discrete and need to be assessed independently using specific tasks. Ten separate sub-tests assess the major domains of cognitive functioning: orientation, attention, language, spatial skills, memory, constructions and reasoning. The results are displayed as a graphic profile of the patient’s cognitive strengths and weaknesses.
Cognistat Five measures orientation, memory and constructions and uses these values, along with the patient’s age and level of education, to provide the MCI Index, which is a risk assessment algorithm for MCI and dementia.
