Accessing the Subtle Cognitive Impairment Test (SCIT) is easy. Each time you run the SCIT you will use up one pre-paid license. All you need to do is decide the number of licenses you would like to purchase.
Subtle Cognitive Impairment Test
The SCIT is sensitive to small changes in the speed of signal processing and in the effectiveness of signal processing, within subcortical and cortical pathways of the brain. The SCIT is able to detect changes before they begin to noticeably affect an individual’s performance on everyday tasks.
People with cataracts or other forms of visual impairment perform poorly on the SCIT. Participants with myopia or other correctable visual disorders can perform normally if they wear their contact lenses or spectacles.
Performance on the SCIT gradually declines with age, but this change can be controlled for by using population norms or by comparing to data obtained from prior tests by the same participant.
Participants who lack a working knowledge of English can have difficulty understanding the written instructions for the SCIT, and should not be tested unless a translator is available.
Performance on the SCIT can be impaired in individuals with a blood alcohol level of 0.05 or higher. It is likely that other recreational, prescribed or elicit drugs will affect performance on the SCIT.
It is preferable to test individuals on the SCIT when they feel rested and alert. Individuals with jetlag or acute sleep deprivation show impaired performance on the SCIT. General tiredness does not affect performance.
Individuals with mild-moderate cognitive impairment (with an MMSE score of 24 or less) find the SCIT difficult and are often unable to complete the test.
Individuals with severe osteoarthritis or Parkinsonian symptoms can find it difficult to press the keyboard buttons, which slows their recorded response times.
Individuals with untreated Coeliac disease or Crohn's disease perform worse than healthy peers on the SCIT. It is possible that other disorders involving systemic inflammation are also associated with impaired performance.
