We propose that the pathophysiology of adult CMI involves a combination of craniocervical abnormalities which leads to tonsillar herniation and reduced compliance of the cervical spinal canal. However, only a small percentage of patients exhibit clinical instability and these theories do not account for asymptomatic herniations. Recently, it has been proposed that CMI symptoms are primarily due to instability of either the atlanto-axial (AA) or the atlanto-occipital (AO) joint and the cerebellar tonsils herniate to prevent mechanical pinching.
However, asymptomatic cases vastly outnumber symptomatic ones and it is not known why some people become symptomatic. Symptoms are believed to be due to the herniation causing resistance to the natural flow of cerebrospinal fluid (CSF) and exerting a mass effect on nearby neural tissue. The pathophysiology of CMI is not well elucidated however, the prevailing theory focuses on the underdevelopment of the posterior cranial fossa which results in tonsillar herniation. Infants may drool excessively, be irritable when feeding, have trouble swallowing and gaining weight, show delayed development, have a weak cry, or experience breathing problems.Chiari malformation Type I (CMI) is characterized by herniation of the cerebellar tonsils through the foramen magnum. Others may experience dizziness, depression, muscle weakness, balance problems, lack of coordination, numbness in limbs, hearing problems, trouble swallowing, insomnia, vomiting or loss of fine motor skills.
Some may have symptoms similar to Gray’s. Patients experience Chiari in a wide variety of ways. This weekend she will present a poster on her research at the conference. Since August she has been earning academic credit at CWRU by working in the UA center’s lab. Surgery created new passages for cerebrospinal fluid to flow and relieved pressure on the brain.īecause of her struggles with Chiari, Gray set about finding a way to contribute to research on the condition. As a teenager she suffered unexplained headaches, neck pain and vision problems until an MRI found a Chiari malformation. Kayla Gray, a graduate student in applied anatomy at Case Western Reserve University, is both a researcher at The University of Akron center and a Chiari patient. A panel discussion, “Voices of Chiari: Patient Experiences,” conducted by three Northeast Ohio Medical University staff members in family and community medicine.A report by Francis Loth, Ph.D., executive director of the Conquer Chiari Research Center, on new findings about how Chiari disrupts the flow of cerebrospinal fluid and how that information can help in diagnosing Chiari and evaluating the success of treatments.A study by Philip Allen, Ph.D., of The University of Akron suggesting that Chiari patients suffer from cognitive problems.A study by Rebecca Santelli, Ph.D., of the University of North Carolina showing that children born to women taking antidepressants during pregnancy may be more at risk to develop Chiari malformation.UA’s two-year-old Conquer Chiari Research Center, the first and only center solely dedicated to researching Chiari malformation, will host the conference. The Conquer Chiari Research Conference, held every two years, is coming to Akron for the first time.
