If you’ve ever had an ear infection, you know how debilitating it can be. The pain is enough to make anyone want to crawl into a dark hole and hide away from the world until it passes. But can inner ear infection cause brain fog?

Unfortunately, yes. If you’re suffering from an inner ear infection, it’s likely that your cognitive function will be affected as well. You may find yourself feeling more forgetful than usual, or struggling to concentrate on simple tasks.

This can obviously have a major impact on your day-to-day life, so it’s important to seek medical attention if you think you might have an ear infection.

What Is an Inner Ear Infection?

An inner ear infection is an infection that occurs in the inner ear.

The most common type of inner ear infection is called otitis media, which is a middle ear infection.

Inner ear infections can also occur in the cochlea, which is the part of the inner ear responsible for hearing.

Symptoms of an inner ear infection may include:

  • Pain in the ear.
  • Fever.
  • Loss of balance.
  • Nausea and vomiting.
  • Ringing in the ears (tinnitus).
  • Hearing loss.

If you experience any of these symptoms, it’s important to see your doctor right away so they can properly diagnose and treat the condition.

Inner ear infections are usually caused by viruses or bacteria entering the body through the nose or mouth and making their way into the middle or inner ears.

In some cases, allergies or environmental factors such as smoke exposure or excessive wax buildup can contribute to developing an inner ear infection.

Treatment for an inner ear infection typically includes antibiotics (if bacterial) or antiviral medications (if viral).

If fluid build-up behind your eardrum is present, your doctor may insert tubes into your ears to prevent future fluid accumulation and reduce pressure on your eardrums.

Surgery to repair any damage caused by the disease process may also be necessary in severe cases.

While inner ear infections are usually not serious, they can be very uncomfortable.

If you think you may have an inner ear infection, see your doctor as soon as possible so they can properly diagnose and treat the condition.

Key Takeaway: Inner ear infections can cause symptoms like pain, fever, balance problems, and hearing loss. Treatment typically includes antibiotics or antiviral medications. Surgery may be necessary in severe cases.

Inner Ear Infection and Brain Fog

Can inner ear infection cause brain fog?

An inner ear infection can cause brain fog by affecting the balance and hearing organs in the inner ear. This can lead to dizziness, confusion, and difficulty concentrating.

Inner ear infections are more common in young children and adults over 65 years of age.

You can prevent ear infections by keeping your ears clean and avoiding exposure to loud noises or sudden changes in pressure such as flying.

If you experience any symptoms of an inner ear infection, such as severe dizziness, vertigo, nausea, vomiting, or fluid drainage from the affected ear(s), see a doctor immediately.

Risk Factors For Inner Ear Infection

Ear infections are one of the most common illnesses in children, but they can occur at any age.

An inner ear infection (also called otitis media) is usually caused by a virus and often follows a cold or upper respiratory infection.

Anyone can get an inner ear infection, but some people are more likely to develop them than others.


Ear infections are very common in young children, particularly those between the ages of 6 months and 3 years old. This is because their immune systems haven’t fully developed yet and their eustachian tubes — the tubes that connect the middle ears to the back of the throat — are shorter and narrower than those of adults, making it easier for bacteria or viruses to enter the middle ear.

In addition, kids this age tend to put things in their mouths a lot which can spread germs from their hands to their ears.

The Elderly

As we age our immune system weakens, putting us at greater risk for developing an inner ear infection as well as other types of infections such as pneumonia or influenza.

In addition, older adults may be more likely to have underlying medical conditions that contribute to decreased immunity such as diabetes mellitus, cancer, and chronic kidney disease.

Also, many medications used to treat these conditions further suppress immunity.

People with Weak Immune Systems

Anything that compromises your body’s ability to fight off illness increases your chances of getting an inner ear infection. These include certain medical treatments like radiation therapy or chemotherapy for cancer patients.

Taking long-term steroids (oral corticosteroids) also decreases immunity, thus predisposing someone to develop an opportunistic bacterial or viral illness when exposed.



Smoking directly damages cells that line various organs including the lungs, thereby weakening overall resistance against invading microorganisms.

Secondhand smoke also has similar immunosuppressive effects on nonsmokers, making them more susceptible to contracting infectious diseases.

Obese People

Being overweight makes it harder to fight off existing infections due to excess tissue which harbors bacteria and provides an ideal environment for pathogens to multiply.

Obesity also puts a person at a greater risk of complications should they happen to contract something.

People With Poor Dental Hygiene

Bacteria can enter the bloodstream through the gums and travel throughout the body, increasing the chance of infecting other sites like your ears.

Stressed Individuals

Both physical and psychological stress can limit the ability of white blood cells to fight inflammation.

While anyone can get an inner ear infection, these groups of people are more susceptible than others. If you fall into any of these categories, it’s important to maintain good hygiene habits, eat a healthy diet, and see your doctor regularly so you can catch any potential problems early on.

Key Takeaway: People with weakened immune systems, smokers, obese individuals, and those exposed to polluted environments or drafty conditions are more susceptible to inner ear infections.

How to Prevent an Inner Ear Infection

If you’re prone to inner ear infections, there are a few things you can do to help prevent them.

  • Avoid swimming or getting water in your ears. When showering, use a washcloth to carefully clean the outer surface of your ear canal without inserting anything inside. Pat the area dry afterward.
  • Don’t put anything smaller than your elbow in your ear canal. This includes Q-tips! Cleaning too far inside the ear could damage delicate tissue and actually lead to an infection.
  • Eat a healthy diet and get regular exercise as this helps boost immunity overall.

If you think you might have an infection, see a doctor as soon as possible.

FAQs on Can Inner Ear Infection Cause Brain Fog

Can an ear infection mess with your brain?

Infections in the ear can be very dangerous, leading to serious conditions such as meningitis, brain abscess, and other neurological complications.

While antibiotic use has greatly decreased the dangers of ear infections, it is still possible to develop severe, life-threatening conditions, such as hearing loss and facial paralysis.

Can vestibular issues cause brain fog?

Symptoms of vestibular disorders include emotional, physical, and mental exhaustion, as well as confusion and disorientation.

Can an ear infection make you feel spaced out?

When the inner ear is infected, the nerves swell and throw off the signals that are sent to the brain, resulting in symptoms of vertigo, nausea and vomiting, and concentration issues.

Can vertigo cause brain fog?

Dizziness and vertigo can cause brain fog, which is when patients feel confused and have difficulty concentrating. Sometimes, this clears up after vestibular physical therapy, but not always.


Can inner ear infection cause brain fog?

It’s true! When the infection spreads to the brain, it can cause inflammation and swelling. This can lead to symptoms like difficulty concentrating, poor memory, and feeling confused.

Treatment for brain fog depends on the underlying cause but may include antibiotics if the infection is bacterial, or steroids if it is viral. If you’re dealing with brain fog, talk to your doctor to find out the best course of treatment for you.
