A neurological disorder in which the pressure within the skull is elevated. This increase can be associated with a space-occupying mass creating a “mass effect,” it can be caused by a Chiari Malformation blocking the flow of cerebrospinal fluid and therefore increasing intracranial pressure. When no cause is seen on MRI, it is usually diagnosed as idiopathic, although they rarely order further testing to explore signs of venous hypertension (which can cause intracranial hypertension).

Examples of space-occupying masses include cranial cysts/tumors, hydrocephalus, or any factor causing edema (such as trauma, infection, disease, or an adverse reaction to certain medications).

One clear and somewhat indisputable fact remains: Intracranial Hypertension (IH) can cause a pushing effect on the cerebellar tonsils, causing an Acquired Chiari Malformation, AND the blockage of fluid associated with a Chiari Malformation increases Intracranial Hypertension, so it is an evolving circle until a successful treatment stops the pressure.

Pseudotumor Cerebri

Bridges are built as a means to assist people in getting over the things that obstruct their path. We are constantly facing obstacles when it comes to our health, so we decided to build a bridge! Chiari Bridges is a non-profit network built by Chiarians for Chiarians. Our goal is to provide information, substantiated by published studies, in a way that is easy to understand. We encourage readers, to not only read our articles, but look up every study for themselves and read that too. Print it out and sit down with a highlighter; read it as many times as necessary until you understand; then use it to talk to your doctors. Our doctors are under no obligation to read our articles, but they should be willing to read officially published studies from journals, especially those specific to their profession. As many of our authors are patients as well, all authors sharing original pieces will be writing under pseudo-ghost names, to protect them from being black-listed by their doctors. Chiari Bridges is not affiliated with any physician or medical group. You should in no way use this site as a replacement for diagnosis, treatment, or medical from a qualified medical professional. The information provided on our website is strictly for educational purposes, in order to help further the understanding of Chiari, and its associated conditions. Our goal is to share our collective experiences and the information we have gathered, with those in need of answers, that it may increase your knowledge and guide you in conversations with your doctors.
