Serial sevens

Serial sevens is a neuropsychological test often used in clinical settings to test for mental function and mental status. It involves subtracting seven from 100, then subtracting seven from the result, and so on. The test is used to assess concentration and working memory.

Overview[edit | edit source]

The serial sevens test is a part of the Mini-Mental State Examination (MMSE), a common tool used in medicine to screen for dementia. It is also used in the assessment of cognitive impairment and mental disorders such as schizophrenia and depression.

Procedure[edit | edit source]

The test begins with the number 100, and the individual is asked to subtract seven. The individual continues to subtract seven from each subsequent number. The test typically continues until the individual reaches zero, or until they have subtracted seven a total of five times.

Scoring[edit | edit source]

Scoring for the serial sevens test is based on the number of correct subtractions. Each correct subtraction is worth one point, with a maximum score of five points. A score of three or less is considered indicative of potential cognitive impairment.

Limitations[edit | edit source]

While the serial sevens test is a useful tool in assessing cognitive function, it has its limitations. It may be influenced by the individual's level of education, as those with less education may have more difficulty with the task. Additionally, it may not be suitable for individuals with certain neurological disorders or learning disabilities.
