Clinical Applications of the Stroop Test

Purpose and Interpretation

The Stroop test evaluates executive functions, including psychomotor speed, cognitive flexibility, and response inhibition, and is useful for detecting executive dysfunction in patients with suspected vascular cognitive impairment (VCI) and individuals with behavioral variant frontotemporal dementia (bvFTD) 1, 2, 3, 4, 5
The American Academy of Neurology recommends the Stroop test as part of comprehensive neuropsychological assessments for differential diagnosis between neurodegenerative conditions and psychiatric disorders, and for assessment of cognitive impairment following stroke 2, 3, 6, 7
The Stroop test is sensitive to subtle executive dysfunction and can detect cognitive changes in patients with liver disease, making it a valuable tool for monitoring cognitive impairment in these populations 1, 2, 3

The Stroop test should be interpreted within a comprehensive assessment battery, taking into account potential confounding factors such as educational level, language proficiency, visual impairments, and cultural background 2, 3, 5, 6
Performance on the Stroop test can be affected by medication effects, fatigue, and test anxiety, and alternate forms should be used when available to avoid practice effects with repeated testing 2, 5
The Stroop test can be used in combination with other assessments, such as the Trail Making Test and the Hayling Sentence Completion Test, to provide a comprehensive evaluation of executive function 2, 3, 8
