NeuroReAlign Therapy for Cognitive Rehabilitation in Patients with Stroke

The Montreal Cognitive Assessment (MoCA) is a widely used screening tool designed to assess mild cognitive impairment in stroke survivors and other neurological populations. It evaluates multiple cognitive domains, including attention, memory, visuospatial abilities, executive function, language, and orientation. The test consists of 30 points, with a cutoff score of <26 suggesting cognitive impairment. The MoCA is sensitive to subtle cognitive deficits and is particularly useful in detecting post-stroke cognitive impairments that may not be captured by other general cognitive tests.

The Mini-Mental State Examination (MMSE) is a brief, standardized cognitive test used to assess overall cognitive function in stroke survivors. It evaluates orientation, attention, memory, language, and visuospatial skills, with a total score of 30 points. Lower scores indicate greater cognitive impairment, with a cutoff of ≤24 typically suggesting cognitive dysfunction. Although widely used, the MMSE may be less sensitive to detecting mild cognitive impairment compared to the Montreal Cognitive Assessment (MoCA).

The Trail Making Test (TMT) is a neuropsychological test used to assess processing speed, attention, and executive function in stroke survivors. It consists of two parts: TMT part A, where participants connect numbers in ascending order to measure processing speed and visual search, and TMT part B, where they alternate between numbers and letters (1-A-2-B, etc.) to assess cognitive flexibility and executive function. Longer completion times indicate greater impairment. The TMT is widely used to evaluate cognitive deficits following stroke, particularly in domains related to attention and task-switching.

The Stroop Test assesses cognitive control, attention, and response inhibition, which are often affected after a stroke. It requires participants to name the color of printed words while ignoring the actual word meaning (e.g., saying "blue" when the word "RED" is printed in blue ink). The test measures processing speed, selective attention, and executive function by evaluating the ability to suppress automatic responses. Poor performance on the Stroop Test may indicate deficits in cognitive control and attention regulation, which are common in post-stroke cognitive impairment.

The Digit Span Test, a subtest of the Wechsler Adult Intelligence Scale (WAIS), assesses attention, working memory, and verbal short-term memory. Participants are asked to repeat a series of numbers in the same order (forward digit span) or in reverse order (backward digit span). The backward span is particularly sensitive to working memory deficits, which are frequently observed in stroke survivors. This test is simple yet effective in evaluating short-term memory and cognitive processing capacity.

The Verbal Fluency Test (VFT) measures language function, executive control, and processing speed. It consists of two types: phonemic fluency, where participants generate words starting with a specific letter, and semantic fluency, where they list words within a given category (e.g., animals). The number of correct words generated within a time limit (usually 60 seconds) reflects cognitive function, with lower scores indicating language or executive dysfunction. This test is commonly used to assess cognitive deficits in post-stroke patients, particularly those affecting language and retrieval ability.
