The Cerebral Performance Category (CPC) Scale is a neurological scale used in the assessment of patients following a cardiac arrest. This scale is particularly useful in evaluating the neurological outcome of patients after cardiac arrest, and it is often used in research and clinical trials to measure the effectiveness of various interventions. The CPC Scale ranges from 1 to 5, with 1 indicating good cerebral performance or minor disability, and 5 indicating brain death. There are no specific exclusion criteria for its use, but it is most applicable to patients who have experienced a cardiac arrest.

Cerebral Performance Category (CPC) Scale

# Criteria
 ## Clinical features and level of function
A. Conscious, alert, able to work and lead a normal life; may have minor psychologic or neurologic deficits.
B. Conscious, with sufficient cerebral function for part-time work in a sheltered environment or to do independent activities of daily life; may have hemiplegia, seizures, ataxia, dysarthria, dysphasia, or permanent memory or mental changes.
C. Conscious, but dependent on others for daily support (in an institution or at home with exceptional family effort) with at least limited cognition; includes a wide range of neurologic dysfunctions, from ambulatory patients with severe memory disturbances or dementia precluding independent existence to paralyzed patients able to communicate only with their eyes.
D. Unconscious, unaware of surroundings, no cognition, no verbal or psychological interaction with the environment.
E. Meeting criteria for brain death (such as apnea, areflexia, electrocardiogram silence)
