Introduction

Understanding vertigo and tinnitus

Tinnitus and vertigo are primarily conditions that affect the inner ear, however they can also affect the brain. Tinnitus is characterized by a ringing or buzzing sensation in the affected ear(s) while vertigo is characterized by feelings of dizziness or spinning impacting balance and focus.¹ 

What is vertigo? 

Dizziness is a broad term that people use to describe different feelings, including:

• Feeling like you might faint
• Feeling light-headed
• Feeling off-balance or unsteady
• Having a vague or swimmy-headed sensation

Vertigo is a symptom in which you may feel like your surroundings are spinning, even when this is not the case. Vertigo isn't a diagnosis, but rather a symptom. A good way to describe vertigo, is the feeling you get when you spin around and then suddenly stop, but the spinning sensation continues. Sometimes, it might feel like you're being pulled to one side.

During spells of vertigo, individuals may also feel nauseous, vomit, have trouble keeping their balance, or find it hard to walk. Some might notice their eyes jerking rhythmically (called nystagmus) during an episode.

Different people use the terms "dizziness" and "vertigo" differently, probably because it's tough to put these feelings into words. Additionally, the sensations might change over time, what feels like light-headedness one moment might feel like vertigo the next.²

Vertigo can be classified as being peripheral or central:³

Peripheral vertigo usually results from issues with the part of the ear that controls your balance or from the vestibular nerve, which connects the inner ear to the brain.

Causes of peripheral vertigo include:

• Medicines like certain types of antibiotics, cisplatin, diuretics or salicylates which can cause damage to inner ear structures
• Head injury
• Swelling and inflammation of the vestibular nerve
• Irritation of the inner ear
• Meniere disease
• Pressure on the vestibular nerve

Central vertigo is caused by a problem in the brain and may be due to:

• Blood vessel disease
• Medication such as aspirin and anticonvulsants
• Multiple sclerosis
• Seizures
• Stroke
• Tumours
• Vestibular migraines

Central vertigo may be accompanied by other neurological symptoms like:

• Difficulty swallowing
• Double vision
• Abnormal eye movements
• Facial paralysis
• Slurry speech
• Limb weakness

What is tinnitus? 

Tinnitus, or ringing in the ears, is when you hear noises that do not come from the outside world. It is a common symptom, about 10 to 15% of people experience it to some extent. The noise can present as buzzing, ringing, roaring, whistling, or hissing, and often happens alongside hearing loss. Some people might hear more complex sounds that change over time. Tinnitus is usually more noticeable in quiet places, especially when you're trying to sleep. But how bothersome it is varies from person to person.

There are two main types of tinnitus: subjective and objective. 

• Subjective tinnitus is most common and is linked to abnormal brain activity in the area that deals with sound. Doctors aren't entirely sure why this happens.
• Objective tinnitus is rarer and involves actual noise created by structures near the ear like blood flow through arteries or veins. Sometimes, others can even hear these sounds.

Many things can cause ringing or buzzing in the ears. Subjective tinnitus is often tied to issues with the ears, like exposure to loud noises, ageing, certain medications, or conditions like migraines or Meniere's disease. It can also be linked to problems like ear infections, excess ear wax, or issues with the tube that connects the ear and nose. Objective tinnitus usually happens because of blood vessel issues near the ear, like turbulent blood flow or certain tumors.⁴

What is the relationship between vertigo and tinnitus?

The two conditions are not connected but can occur simultaneously. While not everyone with tinnitus experiences vertigo, these two conditions frequently coexist. For instance, individuals with Meniere’s disease and vestibular schwannoma, also known as an acoustic neuroma) typically encounter both tinnitus and vertigo. Moreover, tinnitus might intensify significantly before the onset of vertigo. 

One possible explanation for their relationship is the close proximity of the auditory and vestibular systems within the inner ear. Dysfunction in one system may affect the other, leading to the simultaneous occurrence of vertigo and tinnitus. Additionally, certain underlying conditions, such as inner ear infections or vestibular migraines, can trigger both symptoms.This suggests that there may be common underlying mechanisms or triggers for both conditions.

These two independent conditions often go hand in hand, with one sometimes worsening the other.This article discusses various ways to manage these symptoms, including medications, therapies, and lifestyle changes. It aims to help both patients and healthcare professionals better understand and address these challenging conditions.

Mechanisms underlying vertigo and tinnitus

Vertigo often happens when there are problems with the parts of your ear and brain responsible for keeping you balanced. There may be problems in your:

• Inner ear
• Brain stem and cerebellum
• Nerve tracts connecting the inner ear to the brain stem and cerebellum

Even though the symptoms can be really bothersome and make it hard to function, only a small number of cases are caused by a serious problem.

Diagnosis of vertigo and tinnitus

Here's some helpful guidance for people experiencing dizziness. This will help you to decide whether a doctor should be seen and what to expect during the visit:

Warning Signs: If you're dealing with dizziness, and you are experiencing some red flags like headaches, neck pain, trouble walking, fainting, or other unusual neurological symptoms (like hearing or seeing issues, difficulty speaking or moving limbs), you should seek out medical advice.

Seek help if: 

• you are experiencing any of the warning signs
• your symptoms are severe
• symptoms have continued for over an hour
• you have been vomiting

Head to the hospital as soon as possible. Otherwise, it's a good idea to see your doctor soon. If you've only had a short, mild episode with no other symptoms, you might wait to see if it happens again

What to expect at the doctor's office:² 

• Medical history
• Questions describing your symptoms 
• Describe the severity of the symptoms
• Have you experienced any falls or fainting episodes
• Have you missed work
• Are you vomiting
• Do you have ringing in your ears
• Do symptoms come and go or are they permanent
• Clinical examination 
• Look inside the ears
• Test hearing
• Test eye movement
• Based on what they find, they might suggest some tests (e.g. MRI)

Management approaches

Here's how we can tackle tinnitus and vertigo:

Pharmacological interventions

This means using medicines to help with the symptoms. For example, there are medications that can help reduce dizziness or ringing in the ears.

Non-pharmacological interventions 

These are treatments that don't involve medicines. Things like physical therapy exercises to improve balance, or techniques to help you relax and manage stress can be really helpful. They aim to improve balance and reduce dizziness.

Surgical options

In some cases, surgery might be an option. This could involve procedures to fix problems in the ear or brain that are causing the symptoms. However, surgery is usually considered only if other treatments haven't worked or if the symptoms are severe.

Lifestyle modifications and coping strategies

Making changes in your daily life, like adjusting your diet or finding ways to relax, can sometimes help ease the symptoms of tinnitus and vertigo. Coping strategies might involve things like stress-reducing techniques or joining support groups to talk with others going through the same thing.

Future plans and research needs

Researchers are always working on finding new ways to understand and treat tinnitus and vertigo better. They're exploring new treatments, technologies, and ways to improve the lives of people dealing with these conditions. In the future, we might see even more effective methods for managing these symptoms and improving quality of life.

Summary

It is clear that dealing with tinnitus and vertigo can be challenging, but there's hope. By understanding the relationship between these symptoms and exploring various management approaches, both medical and non-medical, we can significantly improve the quality of life for individuals affected by these conditions.

From medicines to lifestyle adjustments, there are many ways to tackle tinnitus and vertigo. It's essential for individuals to work closely with healthcare providers to find the best combination of treatments that work for them.

Looking ahead, ongoing research holds promise for even better solutions. As scientists continue to explore the underlying causes and mechanisms of these conditions, we can expect to see advancements in treatments and support options. This means brighter prospects for individuals living with tinnitus and vertigo, offering them more effective ways to manage their symptoms and lead fulfilling lives.

In essence, while tinnitus and vertigo can be tough to deal with, there are plenty of options available to help manage them. By staying informed, seeking support, and exploring available treatments, individuals can find relief and regain control over their lives. And with ongoing research, the future looks promising for even better outcomes.
