The document discusses the Glasgow Coma Scale (GCS) and Mini-Mental State Examination (MMSE) which are used to assess impaired consciousness and cognitive status. The GCS evaluates eye opening, motor, and verbal responses on a scale of 3-15 to describe consciousness impairment. The MMSE is a screening tool that assesses cognition on a scale of 0-30, with scores below 18 indicating severe impairment. Both are commonly used for interdisciplinary communication about a patient's brain injury severity and cognitive disorders.
