1. A method of assessing intracranial pressure related to at least one of hydrocephalus and dementia in a human or an animal, comprising the steps of:

  • obtaining a first set of intracranial blood flow data;

    generating at least two blood flow factor values from said first set of intracranial flow data;

    correlating said at least two blood flow factor values; and

    assessing intracranial pressure based at least on said correlated blood flow factor values;

    wherein said at least two blood flow factor values include at least one of a mean flow velocity value, a systolic acceleration value, a pulsatility index value, a natural logarithm of systolic acceleration value, a peak systolic velocity value, an end diastolic velocity value, a peak systolic time value, an end diastolic time value, an acceleration/mean flow velocity index value, a velocity/impedance index value and an acceleration/impedance index value.
