Persistent neck or back pain can impact more than physical health—it can interfere with work, hobbies, and daily activities.

In this PNI Minute, Jean-Philippe Langevin, MD, highlights how the Pacific Neuroscience Institute team approaches spine care by listening to each patient’s challenges, reviewing imaging, and carefully evaluating options. The goal is to consider every avenue, including non-invasive therapies such as massage, yoga, and acupuncture, before moving to surgery—helping patients return to their lives with less pain.

📅 October 7 is National Trigeminal Neuralgia Awareness Day

Trigeminal neuralgia (TN) is a severe facial pain condition often triggered by routine activities such as brushing teeth, eating, or even a light breeze. Symptoms can range from sudden, stabbing pain to ongoing burning discomfort.

The most common cause of classic TN (Type 1) is a blood vessel pressing against the trigeminal nerve at the brainstem, though it may also result from multiple sclerosis, tumors, shingles, or trauma.

At Pacific Neuroscience Institute, our specialists provide advanced medical and surgical treatment options to help patients manage this debilitating condition.

In October 2024, we welcomed back Mamadou to Pacific Neuroscience Institute. Diagnosed with gigantism as a teenager, he faced vision loss, severe headaches, and rapid growth caused by a growth hormone-secreting pituitary tumor.

After an initial surgery elsewhere that could not fully remove the tumor, his family placed their trust in Dr. Daniel Kelly. With the successful outcome, Mamadou not only recovered but went on to achieve a remarkable basketball career at the high school, collegiate, and professional levels.

Now standing 7’6” and in excellent health, Mamadou returned 14 years later to express gratitude to Dr. Kelly, Dr. Chester Griffiths, and nurse practitioner Amy Eisenberg.

With basketball season around the corner, we are honored to reflect on his inspiring story and the impact of compassionate, expert care on patients’ lives.

When patients turn to PNI with complex voice and swallow concerns, they find more than advanced treatment—they find attentive care from physicians who listen.

One patient described their experience with Omid Mehdizadeh, MD:
⁠
“Dr. Mehdizadeh is fantastic. He was professional, attentive, and took the time to carefully listen to all of my concerns. He thoroughly checked every symptom, explained everything clearly, and made me feel comfortable and confident in the care I was receiving. The staff was equally wonderful: friendly, efficient, and scheduling was very easy.”

We’re proud to highlight physicians like Dr. Mehdizadeh, whose commitment to clear communication, thorough care, and patient comfort reflects the values at Pacific Neuroscience Institute.
