Sound Sensitivity After Concussion: Hyperacusis and Its Hidden Causes - Dr. Glen Zielinski | E30
Aug 11, 2025 Episode 30 Ayla Wolf, DAOM

Dr. Glen Zielinski from Northwest Functional Neurology explores commonly missed vestibular lesions that can develop after head impacts, focusing on Superior Canal Dehiscence (SCD) as a frequently overlooked cause of debilitating hyperacusis and other post-concussion symptoms. He shares diagnostic insights including a simple tuning fork test that can identify potential SCD cases.

• SCD creates a resonant cavity near hearing apparatus when the thin bone covering semicircular canals is damaged
• Simple tuning fork test on the knee can identify SCD when patients hear rather than just feel the vibration
• Proper diagnosis requires high-resolution temporal bone CT imaging
• Midbrain dysfunction often presents with combined symptoms of light/sound sensitivity, anxiety, and vestibular issues
• Hear the story of how Dr. Zielinski's clinic won architectural awards for its therapeutic design specifically engineered for brain injury patients
• Special features include specific shades of green for photophobia and felt materials that absorb aggravating sound frequencies
• The physical environment itself becomes part of the treatment approach
