Which sign is a late indicator of increased intracranial pressure?

Rising intracranial pressure progresses from early, subtle signs to a decompensated state. The late indicator is Cushing's triad: a noticeably high systolic blood pressure with a wide pulse pressure, a slow heart rate, and irregular or/and slowed breathing. This combination shows the brain is losing the ability to compensate and brainstem function is being compromised. The elevated blood pressure is the body's attempt to keep cerebral perfusion up as pressure rises, but the resulting bradycardia and abnormal respirations reflect core brainstem distress and impending herniation. Other signs like a change in level of consciousness or pupil changes can occur earlier or with different mechanisms, so they don’t specifically mark the late decompensation that Cushing's triad represents.
