Dizziness and Vertigo (Spinning Sensations)

Vertigo is a feeling of imbalance. If you have this dizziness, you may feel you are spinning or the world around you is spinning. Many people use the term to describe the fear of heights, but this is incorrect. This can happen when a person looks down from a great height and refers to symptoms of temporary or continuous dizziness caused by inner ear or brain problems.

It is not a disease but a symptom. Many conditions can cause it and can occur alongside other symptoms, such as:

Types of vertigo

It can be divided into two types:

• Peripheral vertigo
• Central vertigo

Peripheral vertigo arises from complications in the inner ear or the vestibular nerve. The vestibular nerve connects the inner ear to the brain.

Central vertigo happens when there is a problem in the brain. Causes can include

• stroke
• Traumatic brain injury
• infection
• brain tumor
• multiple sclerosis

Vertigo Causes

Several conditions can cause vertigo, which typically involves an inner ear imbalance or a problem with the central nervous system (CNS). The following conditions can cause it.

• Benign Paroxysmal Positional Vertigo (BPPV):This is the most common cause and creates a brief, intense feeling that you are spinning or moving. These episodes are caused by a sudden shift in the brain's movement, such as a blow to the head.
• Infection:Vestibular neuritis, a viral infection of the vestibular nerve, can result in severe, persistent dizziness.
• Meniere's disease:When extra fluid builds up in the inner ear, the result can be unexpected episodes of dizziness that last for a few hours.
• Migraine:Migraine-induced vertigo can last from minutes to hours.

Other causes are:

• Head injury
• Ear surgery
• A perilymphatic fistula is when fluid from the inner ear leaks into the middle ear because of a tear in either of the two membranes between the middle ear and the inner ear
• Herpes zoster in or around the ear (herpes zoster oticus)
• Otosclerosis is a bone growth problem in the middle ear that leads to hearing loss
• Syphilis
• Ataxia, which leads to muscle weakness
• A stroke or transient ischemic attack, which people sometimes refer to as a mini-stroke
• Cerebellar or brainstem disease
• Acoustic neuroma, which is a benign growth that develops on the vestibulocochlear nerve near the inner ear
• Multiple sclerosis

Vertigo Symptoms

• Spinning Sensation: The main symptom of vertigo is feeling like you or your surroundings are spinning or moving while remaining still, often causing intense disorientation.
• Dizziness: Vertigo can cause a general sense of dizziness or lightheadedness, where you feel unbalanced or as though you might faint, particularly when standing up or moving.
• Loss of Balance: A key symptom of vertigo is loss of balance, where you may feel tilting or swaying, making it difficult to stand, walk, or even sit still.
• Nausea and Vomiting: The spinning sensation of vertigo can cause vomiting and, in severe cases, nausea, which may worsen symptoms and lead to dehydration.
• Tinnitus: Vertigo often includes tinnitus, a ringing or buzzing sound in the ear, which can worsen disorientation and discomfort.
• Headache: Headaches, especially migraines, can occur alongside vertigo. The intense vertigo symptoms can trigger or be accompanied by severe headache pain, intensifying the overall discomfort.
• Sweating: Excessive sweating is common with vertigo, often occurring during or after episodes due to the body's response to dizziness or imbalance.
• Difficulty Focusing: Vertigo's confusing effects can impair concentration and focus, making it difficult to stay alert and interfering with daily chores and interactions.
• Inability to Walk Straight: Walking straight can become nearly impossible due to balance issues. The loss of stability might lead to a wobbly or unsteady gait, and you may have difficulty walking without assistance.
• Blurred Vision: Some people with vertigo experience temporary vision impairment, such as blurriness or double vision. This can result from the disorientation caused by vertigo or as part of a broader vestibular issue affecting eye movement coordination.

When to Visit a Doctor?

See a doctor if you have any chronic, sudden, extreme or persistent dizziness:

• Sudden severe headache
• chest pain
• Shortness of breath
• Numbness or paralysis of the arms or legs
• Fainting
• Double vision
• Fast or irregular heartbeat
• Confusion or trouble speaking
• Stumbling or difficulty walking
• Continual vomiting
• Seizures
• A sudden change in hearing
• Facial numbness or weakness

In the meantime, the following self-care tips will help:

• Move slowly: Step slowly as you get up from sitting down. Many people experience dizziness if they get up too quickly.
• Drink plenty of liquid: Staying well-hydrated can help prevent or relieve various types of dizziness.
• Avoid caffeine and tobacco: These substances can block blood flow, which may worsen the symptoms.

Vertigo vs Dizziness

Vertigo Diagnostic Tests

To diagnose vertigo, healthcare providers may perform several tests, including:

• Fukuda-Unterberger Test: You march in place for 30 seconds with your eyes closed. If you lean or rotate to one side, it could indicate an issue with your inner ear labyrinth, causing vertigo.
• Romberg's Test: You close your eyes while standing with your feet together and arms by your sides. If you feel unbalanced, it could point to a problem with your central nervous system (brain or spinal cord).
• Head Impulse Test: Your provider moves your head gently while you focus on a stationary target. Eye movements are observed to determine if there's an issue with your inner ear's balance system.
• Vestibular Test Battery: A set of tests to assess the vestibular portion of your inner ear. It helps determine whether your symptoms stem from an inner ear issue or a brain-related cause.
• Imaging Tests: CT or MRI scans may exclude other potential causes, such as brain lesions or neurological disorders.

These tests help healthcare providers determine the root cause of vertigo and guide appropriate treatment.

Vertigo Treatment

Treatment for vertigo depends on the cause. In some instances, vertigo is gone with no treatment. This is because your brain can adapt to changes in the inner ear, relying on other mechanisms to maintain balance.

• Vestibular rehabilitation: This physical therapy helps improve the vestibular system. The function of the vestibular system is to signal the brain about the movements of the head and body relative to gravity.
• Canalith repositioning maneuvers: These movements move calcium concentrations out of the canal to the chamber in the inner ear so that the body can absorb them. You will probably have vertigo signs during the procedure as the canalitos move. A psychiatrist or physical therapist will direct you through your movements. Movements are secure and sometimes effective.
• Medicine: Sometimes, medications may be given to relieve signs such as nausea or dizziness associated with vertigo. This is caused by infection or inflammation. Antibiotics or steroids can reduce swelling and cure an infection. For Meniere's disease, diuretics (water pills) may be prescribed to reduce the pressure of fluid build-up.
• Surgery: In some cases, surgery may be necessary.

Vertigo Exercises

• Brandt-Daroff Exercises: Sit upright, then move quickly into side-lying positions. Helps desensitize the brain to motion signals.
• Epley Maneuver: Head and body movements reposition inner ear crystals.
• Vestibular Rehabilitation Therapy (VRT): Guided physical therapy for balance and dizziness. Customized exercises from a specialist.

Home Remedies for Vertigo

• Ginger tea can help with feelings of nausea and dizziness.
• Essential oils like peppermint or lavender have calming effects.
• It is important to drink plenty of water to keep your inner ear working well.
• Try to cut back on salt, caffeine, and alcohol, as these can disrupt the balance of fluids in your ears.
• Practicing meditation or deep breathing exercises can help manage anxiety that may cause dizziness.
• Make sure to eat a healthy diet that includes foods rich in magnesium and vitamin D.
