Pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension, is a condition caused by elevated cerebrospinal fluid pressure in the brain. The symptoms of this condition mimic those of a brain tumor, giving it the name pseudotumor cerebri, meaning "false brain tumor." The increased pressure can cause swelling of the optic nerve and can result in loss of vision. Medications can often reduce the pressure and headache, but surgery is necessary in some cases.Alexander M. Solomon, MD, is a neuro-ophthalmologist and strabismus surgeon at Pacific Neuroscience Institute in Santa Monica and Torrance, CA.

A meningioma is a type of tumor that arises from the meninges, which are the protective membranes that surround the brain and spinal cord. It is typically a slow-growing, usually benign tumor, derived from the cells of the arachnoid cap cells or the meningeal cells themselves. Meningiomas are the most common primary brain tumor. Fortunately, most are benign and slow-growing although up to 10% can grow rapidly. They are more common in women than men and can occur in all ages but are typically seen in middle-aged and older adults. Most meningiomas needing surgery can be removed through one of several minimally invasive keyhole approaches.

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.

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.
