Which cognitive skill is primarily tested by the “attention” domain in MoCA?

The "attention" domain in the MoCA (Montreal Cognitive Assessment) is primarily focused on assessing an individual's ability to maintain focused concentration. This domain evaluates skills such as the ability to sustain attention over a period, which is crucial for cognitive functioning in daily tasks. Tasks that require attention may include recalling sequences of numbers or letters, which test not only the retention of information but also the ability to concentrate on that information without distractions.

Focused concentration is vital for effective cognitive processing and is a strong indicator of overall cognitive health. Individuals who have difficulty with this domain may experience challenges in everyday activities that require sustained mental effort, which could be reflective of cognitive decline or impairment.
