Which findings best describe signs of increased intracranial pressure?

Which findings best describe signs of increased intracranial pressure?

• A. Mental status changes, abnormal pupil findings, motor/sensory deficits, and Cushing's triad
• B. Fever, rash, leukocytosis
• C. Isolated tremor and bradykinesia
• D. No symptoms until stroke

Answer: (A)

Elevated intracranial pressure affects brain tissue broadly and can compress structures in the brainstem, so the most reliable signs are changes in consciousness, pupil function, motor/sensory findings, and brainstem respiratory control. Mental status changes reflect reduced cerebral perfusion as pressure climbs, ranging from confusion to drowsiness or coma. Abnormal pupil findings occur because pressure can compress the oculomotor nerve, leading to unequal or nonreactive pupils as ICP rises. Motor and sensory deficits arise from compression of motor pathways and cortical areas, producing focal weakness or sensory changes. The Cushing’s triad—high blood pressure with a wide pulse pressure, bradycardia, and irregular respirations—signals brainstem ischemia and impending herniation, a late but critical warning of ICP worsening. Fever, rash, and leukocytosis point toward infection rather than ICP. Isolated tremor and bradykinesia suggest extrapyramidal or degenerative disorders, not acute ICP changes. No symptoms until stroke describes a different clinical pattern and does not capture the typical ICP signs.
