⭐️ Brain Matters Special Edition | December 2025 ⭐️

As the holiday season leads us into a new year, we take a moment to reflect on 2025 with gratitude in this special issue of the PNI Brain Matters Newsletter.

Early this year, our Los Angeles community was deeply affected by the devastating wildfires that swept through the area. Many homes were destroyed, and countless families faced uncertainty and loss. Yet, even in the face of hardship, we witnessed the incredible strength and compassion that define our community.

An inspiring example came from one of PNI's founders, Dr. Chester Griffiths, who, alongside his son and neighbor, bravely fought to protect their Malibu neighborhood during the fires. Equipped with fire hoses, they worked tirelessly for four days and five nights to defend six homes—standing together against overwhelming odds.

The Importance of Making a Difference

Stories like Dr. Griffiths' highlight the dedication, courage, and compassion at the heart of the Pacific Neuroscience Institute. In that same spirit and because today is Giving Tuesday, we invite you to explore 3 programs—and the physicians who lead them—that transform our patients' lives.

⭐ Facial Nerve Disorders Program: Rebuilding Confidence

The Facial Nerve Disorders Program offers advanced care for those facing facial paralysis and related conditions. The team understands that facial movement is deeply tied to how we express ourselves and connect with others. With an emphasis on shared decision making, each patient's treatment plan is personalized, combining expertise from multiple specialties—including neurosurgery, otolaryngology, ophthalmology, neurology, facial plastic surgery, physical therapy, and speech pathology—to restore both function and confidence.

Specialists at the Cochlear Implant Program restore hearing and improve the quality of life for both adults and children who no longer benefit from hearing aids.

Our multidisciplinary team combines expertise in otology, audiology, neurology, and rehabilitation to guide each patient from diagnosis to long-term hearing success. From evaluation and surgery to activation and auditory training, every step is designed to provide comfort, clarity, and ongoing support.
