The Montreal Cognitive Assessment (MoCA) is a brief, 30-question test that helps healthcare professionals detect cognitive impairments very early on, allowing for faster diagnosis and patient care. MoCA empowers healthcare professionals and researchers to detect cognitive impairment related to conditions such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Lewy Body Dementia, VCI/Stroke, frontotemporal dementia, brain metastasis, ALS, sleep behavior disorder, brain tumors, multiple sclerosis, head trauma, depression, schizophrenia, heart failure, substance abuse, HIV, COVID, and more. MoCA is regularly used by nurses, primary care and specialty physicians, occupational therapists, speech-language pathologists, psychologists, researchers, and other clinicians. It quickly and accurately assesses short-term memory, visuospatial abilities, executive functions, attention, concentration and working memory, language, and orientation to time and place.
