Thyroid nodules are growths on your thyroid. They are usually benign (not cancer). They may become overactive and make too much of the thyroid hormone.

All types of hyperthyroidism are due to an overproduction of thyroid hormones. Hyperthyroidism (an overactive thyroid) causes your thyroid to make more thyroid hormone than your body needs. Hyperthyroidism can accelerate your body functions such as your metabolism (can cause unintentional weight loss) or a rapid or irregular heart rate.

Multiple sclerosis (MS) is a chronic autoimmune neurological disorder that affects the central nervous system, specifically the brain and spinal cord. In multiple sclerosis, the body’s immune system mistakenly attacks the protective covering of nerve fibers, called myelin, in the central nervous system. This immune-mediated damage disrupts the normal flow of electrical impulses along the nerves, leading to a wide range of neurological symptoms.

For people with MS, exercise and physical activity can be variously challenging. However, being physically active is one of the most beneficial adaptations to a lifestyle with MS. The six pillars of brain health are nutrition, exercise, sleep, stress management, social connection and avoidance of risky substances. Advice and educational resources in these areas are part of our neurologic treatment plan.

Hemifacial Spasm is a potentially debilitating condition where the facial muscles of expression spasm uncontrollably. Botulinum toxin can control the spasm, but in severe cases, minimally invasive surgery for microvascular decompression of the facial nerve is more efficacious.

Listen to Chris B's story as he dealt with this issue and sought definitive care at the Pacific Neuroscience Institute with Dr. Garni Barkhoudarian and Dr. Melita Petrossian.

The Pacific Brain Tumor Center and Pacific Pituitary Disorders Center offers a 1-year neurosurgery fellowship in minimally invasive surgery for brain, pituitary and skull base tumors. Our clinical training program is focused on endoscopic endonasal and keyhole surgical approaches, neuro-endoscopy, pituitary tumor management and multimodality neuro-oncology treatments. The fellowship emphasizes operative and peri-operative patient management, outpatient evaluation of new patients and follow-up patients as well as clinical and anatomical laboratory research projects. The fellowship is integrated into the Saint John's Cancer Institute Surgical Oncology Fellowship.

Qualified applicants must have completed training in an ACGME-accredited neurosurgical residency program and be eligible for a California medical license.

Our memory isn't just a passive function. Just like our muscles, it's something that can be trained, optimized, and protected. Subtle changes in our memory can signal the earliest stages of cognitive decline, but preventative interventions can make a huge difference. That's exactly what Dr. Karen Miller, Senior Director of the Brain Wellness and Lifestyle Program at PNI, helps her patients achieve. Dr. Miller specializes in personalized approaches to improve brain health. One technique is the "memory palace," a method that links information to familiar places and strengthens one's ability to recall information. In this episode, learn how Dr. Miller combines cognitive training with lifestyle factors like exercise, nutrition, and social engagement to help patients preserve and improve their brain health.

Spinal disorders may be caused by spine trauma, genetic components or disease including cancer. As the backbone is made of bone, a misconception is that all spine issues are taken care of by orthopedic surgeons. In reality, neurosurgeons are integrally involved in spinal surgery due to the delicate nature and proximity of major nerves in these regions.

To meet the need for a specialty spine center in the South Bay area, in 2019, Providence Little Company of Mary Medical Center Torrance opened its state-of-the-art Spine Institute, bringing together a multidisciplinary team of surgical experts of neurosurgeons and orthopedic surgeons, and capitalized on the hospital’s already nationally recognized rehabilitation centers.

The Spine Institute at Providence Little Company of Mary is now the only comprehensive spinal treatment center in the South Bay. The institute cares for all emergency and conventional neuro-spinal disorders, focusing on advanced minimally invasive spinal procedures.

A cochlear implant for hearing loss is an electronic device that is implanted into the inner ear (the cochlea) and is used to restore hearing in patients who no longer benefit from traditional hearing aids or have hearing loss in just one ear. While a cochlear implant does not re-create normal hearing, it allows individuals to understand speech and perceive sounds in a way that improves communication and quality of life.

Mathilde Tranberg is the dedicated Cochlear Implant Outreach Ambassador at Pacific Head & Neck, Pacific Neuroscience Institute. Mathilde was born profoundly deaf and received Cochlear Implants when she was 2 and 6 years old. As a bilateral cochlear implant (CI) user and the 84th recipient of a CI in Denmark, she knows firsthand the transformative power of this technology.

Her goal is to share her personal journey and empower others with the knowledge and confidence to embrace improved quality of life through better hearing. Mathilde has always been very active and loves playing all kind of sports.

While traveling with her family, 17-year-old Malia experienced a grand mal seizure while she was sleeping. Her parents immediately brought her back to Los Angeles to the care of Dr. Walavan Sivakumar at Pacific Neuroscience Institute South Bay, in Torrance, Ca. An MRI showed that Malia had an Arteriovenous Malformation which likely had been growing for a few years. Learn more about the life-saving surgery and treatment that Dr. Sivakumar and the multi-specialty team at PNI-South Bay and Providence Little Company of Mary Torrance performed to put Malia back on course to live a long and full life.

Cochlear implants are leading a revolution in the treatment of hearing loss. According to a 2022 study, only about 10% of those who qualify for cochlear implants have received them. Cost, accessibility, and lack of awareness are only some roadblocks for potential patients. At Pacific Neuroscience Institute, Dr. Courtney Voelker and Dr. Chester Griffiths are working to change that. Dr. Voelker is recognized as one of the nation’s top cochlear implant surgeons, with patients as young as five months old. Dr. Griffiths is the founder of Pacific Head & Neck, a premier clinic in Los Angeles. Because hearing loss is the leading modifiable risk factor for cognitive decline, addressing it is vital. Tune in to hear how these two doctors are raising awareness about cochlear implants and making a difference in people’s lives.

Smell loss after viral infections can be difficult to manage. Dr. Yong uses various techniques to target smell recovery which is a complex process involving neurons in the nose and brain. Smell is intricately linked in both emotional and functional terms with quality of life. Learn more about smell dysfunction and treatment.
