Abstract: A method (20) and device for deriving an estimate of intracranial blood pressure based on motion data for a wall of an intracranial blood vessel, intracranial blood flow velocity, and a blood pressure signal measured at a location outside the brain. The method is based on identifying (28) a time offset between the two intracranial signals (vessel wall movement and vessel blood flow), and then applying (30) this offset to the blood pressure signal acquired from outside the brain to obtain a fourth signal, indicative of estimated intracranial blood pressure.
