Mild Cognitive Impairment Diagnostic Tests
Cognitive function is assessed in four cognitive categories, known as cognitive domains.3
- Executive functioning (e.g., reasoning, problem-solving, and planning)
- Language (e.g., comprehension, fluency, and semantic paraphasia [when an entire word is substituted for another word, such as saying “orange” instead of “apple” to refer to describe an apple])
- Visuospatial skills (movement, depth and distance perception, and spatial navigation – abilities needed for driving, for example)
- Attentional control (e.g., an individual’s ability to concentrate)
