Adam N. Mamelak, MD

  • Co-Director of the Pituitary Center

Neurosurgeon Adam N. Mamelak, MD, specializes in pituitary and skull base surgery and is one of only a few specialists nationally who uses an endoscopic approach through the nostrils to remove tumors of the pituitary region. This minimally invasive procedure results in minimal pain, shortened hospital stays and reduced recovery times.

Dr. Mamelak is conducting research on a device to assist severely paralyzed patients. He also was leading studies that used a synthetic version of a protein found in the venom of the Giant Yellow Israeli scorpion to deliver a dose of radioactive iodine to malignant brain tumors. The protein, TM-601, binds to glioma cells.

Joining Cedars-Sinai in 2005, Dr. Mamelak has held administrative and academic positions at Huntington Memorial Hospital in Pasadena and City of Hope National Medical Center in Duarte. A graduate of Tufts University with a medical degree from Harvard Medical School, he completed a residency in neurosurgery and fellowships in neuro-oncology, epilepsy, and neuroscience research.

He has published numerous articles in scientific journals and is often invited to speak at medical meetings and conferences.
