Apparatus for and method of measuring intracranial dynamics

An apparatus for measuring intracranial dynamics, wherein the apparatus comprises at least one sensing device of the following:

• an electroencephalographic electrode arrangement, which is configured to be in electric contact with skin of a cranium, and sense direct-current electroencephalographic signals from the brain,
• an optic measurement arrangement configured to direct optic radiation toward the brain through the cranium, and receive the optic radiation reflected and/or scattered therefrom, and
• a capacitive sensor arrangement configured to be in proximity without having an electric contact to the skin of the cranium, and sense electric potential signals of the head, and the apparatus additionally comprises
• a data processing arrangement configured to receive electric signals from the at least one sensing device, and determine data on at least one of the following dynamics:
• glymphatic system, 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;
• and
• the data processing arrangement is configured to output of at least one piece of the data on the dynamics through a user interface.
