How to Manage Tinnitus After a Concussion

You’ve probably seen it in an action movie: an explosion goes off next to the hero, and suddenly all the sound fades out, replaced by a high-pitched ringing. That ringing noise isn’t just a dramatic effect; it’s an indication that the character might have sustained a mild traumatic brain injury, such as a concussion.

While Hollywood rarely dwells on the aftermath of such injuries, the ringing sound is a symptom known as tinnitus. Although tinnitus is commonly associated with hearing loss, it can also be triggered by traumatic brain injuries, including concussions. Understanding this connection can help in recognizing symptoms and seeking appropriate treatment.

What is a concussion?

A concussion is a type of traumatic brain injury (TBI) that takes place when a sudden force shakes the brain inside the skull. Picture your brain, cushioned by cerebrospinal fluid, snugly fit within the skull. A jolt or impact to the head can cause the brain to move rapidly, sometimes colliding with the inner walls of the skull. This collision can result in brain cell damage, leading to a concussion.

Common symptoms of a concussion

Symptoms of a concussion can occur right away or may develop over time, lasting from a couple days to several months. These include:

  • Memory loss and confusion
  • Headaches and sensitivity to light
  • Blurred vision or dizziness
  • Slurred speech
  • Nausea or vomiting
  • Delayed response to questions
  • Ringing in the ears (tinnitus)

Not everyone experiences the same symptoms, and their severity can vary depending on the force of impact. While a single concussion usually doesn’t result in permanent brain damage, repeated concussions can lead to more serious, long-term effects.

How do concussions lead to tinnitus?

You might wonder, can a concussion affect hearing and cause that persistent ringing in your ears? The answer is yes. Tinnitus can arise as a result of traumatic brain injuries, including concussions, due to several mechanisms:

  • Hearing Damage from Impact: In certain situations, such as a nearby explosion, the noise itself can damage the tiny hair cells (stereocilia) in the inner ear. These cells play a crucial role in transmitting sound signals to the brain. If they are damaged by loud noise or shockwaves, it can result in hearing loss and tinnitus. In these cases, the concussion and tinnitus share a common cause: the traumatic event.
  • Disruption of the Ossicular Chain: The middle ear contains three small bones known as the ossicular chain, which transmit sound vibrations to the inner ear. A strong impact can displace these bones, affecting their ability to relay sound effectively and leading to tinnitus. This mechanical disruption can be a direct result of the head trauma that caused the concussion.
  • Inner Ear Damage (Labyrinthine Concussion): Sometimes, the inner ear itself is damaged during a concussion, causing what is known as a labyrinthine concussion. This type of injury leads to inflammation and swelling in the inner ear, which can affect hearing and cause tinnitus.
  • Nerve Damage: The auditory nerve, which transmits sound signals from the ear to the brain, can be damaged during a concussion. Any injury to this nerve can disrupt normal hearing processes, resulting in tinnitus.
  • Brain Communication Disruptions: A concussion can damage parts of the brain that process auditory information. When these areas are affected, the brain may misinterpret or amplify sound signals, leading to the perception of ringing or buzzing noises.
  • Meniere’s Disease Triggered by TBI: In some cases, a traumatic brain injury can trigger Meniere’s disease, a condition characterized by fluid buildup in the inner ear. This can cause episodes of vertigo, hearing loss, and tinnitus, often becoming a chronic issue.

Each traumatic brain injury is unique, and symptoms can vary widely from person to person. It’s essential to get a comprehensive evaluation from a healthcare provider if you suspect you’ve sustained a concussion.

Managing tinnitus after a concussion

For many, tinnitus caused by a concussion is temporary and may resolve as the brain heals. However, in some cases, tinnitus can become chronic, lasting for months or even years. Here are some common treatment strategies:

Sound therapy and masking devices

Sound therapy involves using external noise to help reduce the perception of tinnitus. Masking devices, similar to hearing aids, produce soothing sounds tailored to your specific tinnitus, helping to drown out the ringing.

Hearing aids

When hearing loss is present alongside tinnitus, a hearing aid can help amplify external sounds, making the tinnitus less noticeable. By improving overall hearing, the brain can focus on external noises rather than the internal ringing.

Cognitive behavioral therapy (CBT)

CBT can help patients learn to cope with the stress and anxiety caused by tinnitus. This therapy aims to change the way individuals perceive tinnitus, reducing its impact on their daily lives. Over time, patients may learn to ignore the ringing, lessening its perceived intensity.

Medications and lifestyle adjustments

While no specific medication can cure tinnitus, some patients find relief from medications that address underlying conditions, such as anxiety or insomnia. Lifestyle changes, like reducing exposure to loud noises and managing stress, can also help alleviate symptoms.

Seeking professional help for tinnitus

If you’ve experienced a concussion and are noticing ringing in your ears, it’s important to consult a specialist. Early diagnosis and treatment can significantly improve your quality of life and help manage symptoms effectively. A tailored treatment plan, based on your specific condition and needs, can help reduce the impact of tinnitus.

The road to recovery

Experiencing a concussion can be unsettling, especially when accompanied by persistent tinnitus. However, it’s important to remember that tinnitus caused by a traumatic brain injury can often be managed successfully. With the right approach, including proper diagnosis and personalized treatment, you can work toward reducing the ringing and improving your hearing health.

Don’t wait to seek help. If you’ve recently experienced a head injury and are struggling with tinnitus, find a specialist in your area today to explore your treatment options and start your journey toward recovery.
