Cognitive tests are an important tool for the evaluation of mental function in patients of all ages, ranging from kids with problems in school, or those with Attention Deficit Hyperactivity Disorder (ADHD) or other neurological disabilities, to the relatively more common amnesia and dementia in the adult population, to the diseases like Alzheimer’s and Parkinson’s of old age.
Cognition is how the brain performs the most basic of its tasks that collectively make up how a person thinks, talks and writes or acts towards a certain idea or something. It involves the mental functions of awareness, comprehension, consciousness and imagination, as well as other higher functions that make each personality different from another.
What are Cognitive tests and how they work?
Cognitive test tends to focus more on the location of the disease process happening within the brain rather than concerning itself with the pathology of the lesion, which is made possible by the mapping out of the areas which normally have some certain functions associated with them, the deterioration of which signify some disturbance in that area which normally handles those operations that are affected.
What is the function of Cognitive tests?
The basic functions of any cognitive test is to establish the competency of the subject in the processes of orientation, attention, language, memory, executive function, praxis, visual-spatial coordination and general neurological assessment along with a general impression of the person.
This combined with a detailed history and an account of a close relative or parent can be helpful in achieving a working diagnosis.
What are some common cognitive experiments?
The serial position experiment is one test for memory function, which implies that if given some information as a series of names or numbers, we are more likely to remember the ones at the beginning and the end, while forgetting those in the middle.
A word superiority test is used to evaluate speech and language capabilities and works by displaying a word for the smallest instant of a second, and then asking the subject to remember a letter which was part of the original word.
Memory span works by showing the subject some objects in a specific sequence, from similar sounding words to unrelated and difficult words, which they are then asked to recall in the sequence that they appeared in.
Who administers these Cognitive tests and where?
The cognitive tests can be carried out by health care professionals under a controlled hospital environment as well as clinical psychologists and their research assistants in schools or places like old homes or psychiatric centers. The advances in science and medicine have made possible the early screening and diagnosis of certain debilitating neurological diseases which can be evaluated and managed in a better way by the use of tools like these.
