Dr. Joshua Bederson, MD

Bio

Recognized internationally as a superb neurosurgeon, an outstanding teacher and clinical investigator, Dr. Bederson continues more than a century of neurosurgical excellence at Mount Sinai. 


Drawing on best practices from colleagues across the Medical Center, he is building on this legacy with an innovative multidisciplinary approach to caring for patients with complex intracranial and spinal pathology.


Dr. Bederson has performed more than 2,500 neurosurgical operations at the Medical Center ranging from the treatment of meningiomas, schwannomas and cranio-pharyngiomas, to pituitary tumors, giant intracranial aneurysms, and acoustic neuromas.  His vascular practice includes the treatment of arteriovenous malformations, cavernous malformations, and carotid artery disease. 


An advocate of collaboration with other accomplished physicians and scientists at Mount Sinai, Dr. Bederson developed one of Mount Sinai’s first interdisciplinary clinical programs with the Department of Neurology Stroke Program, and fosters deep collaborative efforts with the Departments of Radiology, Orthopedics, Medicine, Radiation Oncology, Pediatrics, Otolaryngology, Emergency medicine, Rehabilitation Medicine, the Cancer Institute, and the Translational Neuroscience Center. He established the first basic science lab in the Department of Neurosurgery, developing models of stroke and subarachnoid hemorrhage, and was the first Mount Sinai neurosurgeon to obtain an NIH R01 award as principal investigator.  Dr. Bederson previously directed the highly sought-after Neurosurgery Residency Program, and his residents have graduated to neurosurgery positions at prominent medical centers. 


 


Dr. Bederson has held leadership positions with various medical societies, including Chair of the American Association of Neurological Surgeons/Congress of Neurosurgeons Cerebrovascular Section, and Chair of the American Heart Association's writing group on subarachnoid hemorrhage.  He is the author of dozens of peer-reviewed papers, books, book chapters, and monographs focusing on neurosurgery and has received such honors as the Henry B. Newman Award from the San Francisco Neurological Society (1986) and the Cornell University Class of 1979 Top 25 Distinguished Classmates Award (2004).  


 


Dr. Bederson earned his medical degree and completed a residency in neurosurgery at the University of California in San Francisco.  While a resident, he did advanced-study programs in neuropathology at the University of Torino in Italy—as well as microvascular and skull-base neurosurgery programs at the University Hospitals of Zurich, Switzerland, and the University Medical Center in Ljubljana, Slovenia, and a cerebrovascular-surgery fellowship at the Barrow Neurological Institute.  An accomplished sculptor, he studied art at New York University and has exhibited his work, many of which depict human anatomy. Dr. Bederson joined the Mount Sinai faculty in 1992 as Director of The Clinical Program for Cerebrovascular Disorders and served as Vice-Chairman of Neurosurgery from 2001 until 2008, when he became Chairman.

    What is an acoustic neuroma?
    Acoustic neuroma is a benign tumor that arises from the nerves of hearing and balance and grows in the space between the ear and the brain. These tumors usually present with hearing loss in one ear, but with the advent of MRI scanning smaller tumors are discovered before they cause any symptoms....  Full Post

    What is the function of luteinizing and follicle-stimulating hormones?
    Luteinizing and follicle-stimulating hormones control the production of testosterone, estrogen, sperm, and egg maturation and release.

    What is the function of thyroid-stimulating hormone (TSH) in the body?
    TSH causes the thyroid gland to produce two hormones, triiodothyronine (T3) and thyroxine (T4), which help control the body's metabolism.

    When do symptoms of pituitary tumors show up?
    Symptoms arise when the tumors cause either excess or reduced production of pituitary hormones or when the tumor presses on adjacent structures. Symptoms and changes in bodily function vary depending upon which lobe of the pituitary gland is affected and the type of tumor.  Full Post

    What is stereotactic radiosurgery?
    Stereotactic radiosurgery is a treatment for brain tumors, such as meningiomas. In stereotactic radiosurgery, low-dose radiation beams penetrate the brain from different angles. The dosage is low enough to ensure that the healthy brain tissue the beams pass through receive minimal exposure, but significant...  Full Post

    What is awake brain surgery?
    Awake brain surgery is an advanced neurosurgical procedure used to remove brain tumors. During awake brain surgery, you will remain alert and responsive at various times during the surgical removal of infiltrative brain tumors, such as gliomas.

    Brain mapping may also be used if your surgeon is searching...  Full Post

    Does surgery cure meningiomas?
    A small percentage of meningiomas take a more aggressive course and can return or convert to a more malignant type of tumor. Treatment options remain the same for these types of meningiomas: surgery and radiation.

    Chemotherapy may also be appropriate for some more aggressive meningiomas. If your...  Full Post

    Do all meningiomas require surgery?
    The vast majority of meningiomas are permanently cured by simple and safe surgical removal. In certain cases, when the tumor involves critical structures, doctors will remove 95 to 99 percent of it and observe the rest. If the tumor begins to grow back, radiation can stop its growth.

    Meningiomas don't...  Full Post

    How important is early treatment for a meningioma?
    Early treatment of a meningioma can prevent disability. However, if your tumor is slow growing and does not affect your health, your doctor may choose to observe your tumor at scheduled intervals rather than treat it immediately. Your doctor might schedule you for an MRI every few months, and eve...  Full Post

    Who is most likely to develop a meningioma?
    Meningiomas often appear in adults between the ages of 40 and 70 and are extremely rare in children. Women are affected more often than men. A meningioma is the most common benign (noncancerous) brain tumor among men and women 20 years of age and older.  Full Post

    Is a meningioma cancer?
    Most meningiomas are not cancerous. Although the growth of the cells making up the meningioma is uncontrolled, cell growth is usually not rapid enough to qualify as a malignant (cancerous) brain tumor, nor are the cells likely to spread to other parts of the body (metastasis). However, if left un...  Full Post
