The goal of Chiari CARE is to address your individual medical and surgical goals.  There are many specialists involved with the complex care that is often required for those who live with and experience symptoms related to Chiari malformation. Evaluation and treatment at Weill Cornell Medicine Chiari CARE may also involve neurology, radiology, pain nutrition, management, ophthalmology, neuro-ophthalmology, ENT, sleep medicine, neuropsychology, genetics and/or immunology.

We pride ourselves in taking a dynamic, centralized approach to provide you with our neurosurgical expertise, but more importantly we coordinate care with other qualified physicians.  We also recognize that there is a lot that is not definitively known about Chiari and many of its associated disorders. Therefore, we are part of national Chiari clinical trials and have a growing list of internal clinical studies through which we continue to learn about and improve our care for our patients.
