Brain blood flow pulse analysis may help to recognize individuals who suffer from hydrocephalus.

ABSTRACT:

Background

Normal pressure hydrocephalus (NPH) is often associated with altered cerebral blood flow. Recent research with the use of the ultrasonic method suggests specific changes in the shape of cardiac-related cerebral arterial blood volume (C_aBV) pulses in NPH patients. Our study aims to provide a quantitative analysis of the shape of C_aBV pulses, estimated based on transcranial Doppler ultrasonography (TCD) in NPH patients and healthy individuals.

Methods

The C_aBV pulses were estimated using TCD cerebral blood flow velocity signals recorded from probable NPH adults and age-matched healthy individuals at rest. The shape of the C_aBV pulses was compared to a triangular shape with 27 similarity parameters calculated for every reli
