Abstract: An apparatus for measuring intracranial dynamics comprises the at least one sensing device (100): an electroencephalo-graphic electrode arrangement, which senses direct-current electroencephalographic signals from the brain, an optic measurement Marrangement (120), which directs optic radiation toward the brain through the cranium, and receives the optic radiation reflected and/or scattered therefrom, and/or a capacitive sensor arrangement (130), which senses electric potential signals of the head. The apparatus additionally comprises a data processing arrangement (150), which receives electric signals from the at least one sensing device (100), and determine data on at least one of the following dynamics: glymphatic activity, water within the cranium, brain tissue movements, water and/or electrolyte movements and intracranial pressure based on said electric signals from the at least one sensing device (100).
