Just been onto the Human Chiari Site ,and wondered if this information would of a wee bit of interest.
Published 31-7-09.
For several years now Researchers have been using MRI's to Measure Skull Base Dimensions of Chiari Patients in what is know as Morphometrics ,this measures Dimensions of the Skull and the Brain.
The Theory that has emerged is that ,that the Brain is not too Big for the Skull ,but that the Skull is too Small for the Brain
French Researchers have just published their findings,and have made an interesting point ,namely that if the Skull Abnormalities found with Chiari are due to a defect in the early Embryo ,why is there such a range in the age when Symptoms become apparent?
Why is'nt Everyone Symptomatic at a very early age?
One possibility ,as the Authors note, is that there are actually different Mechanisms which can lead to a Mismatch between the Skull and the Brain.
For example ,some Skull Sutures don't fully close until late Teens or Adulthood which could push back Symptoms.
This would imply Chiari is actually a Dynamic Phenomenon,and there are case Studies to support this View
The Paper goes onto mention ,however ,another possibility is that crowding alone does'nt always lead to symptoms .
For example ,perhaps ,perhaps over time Scar Tissue and Adhesions build up which then lead to Symptoms
Could we substitute Cavaliers for Humans in this Paper, could it be making sense. ?
