Chiari malformation

Chiari malformations (CMs) are structural defects in the cerebellum. They consist of a downward displacement of the cerebellar tonsils through the foramen magnum (the opening at the base of the skull), sometimes causing non-communicating hydrocephalus as a result of obstruction of cerebrospinal fluid (CSF) outflow. The cerebrospinal fluid outflow is caused by phase difference in outflow and influx of blood in the vasculature of the brain. The malformation is named for Austrian pathologist Hans Chiari. A type II CM is also known as an Arnold–Chiari malformation in honor of Chiari and German pathologist Julius Arnold.

Hope for Jazmin

I started raising money and awareness for a girl with Chiari to have surgery simply for a Community Awareness competition and it immediately became much more than that. I now know so much more about Chiari, a malformation I didnt even know existed, and have a lot of respect for those who deal with it. It's hard to understand what they go through every day. Chiari causes other things also, such as Scoliosis.

I wanted to share this video because it is a disease I battle with daily. Someday soon, the surgery will be done to make my daily headaches go away. Its not a very well know disease and I wanted to share. Enjoy
