Vertigo in the Elderly: Symptoms, Causes, Diagnosis, and Treatment
Vertigo, a sensation of spinning or dizziness, is a common complaint among older adults. While it can affect people of all ages, the elderly are particularly susceptible to vertigo and its associated symptoms. In this comprehensive article, we will explore the symptoms of vertigo in the elderly, its various causes, and the diagnostic and treatment options available.
Symptoms of Vertigo in the Elderly

The primary symptom of vertigo is a feeling that you or your surroundings are spinning or moving, even when you are stationary[1. Older adults with vertigo may describe their symptoms as:
– Dizziness or lightheadedness
– Loss of balance or unsteadiness
– Nausea and vomiting
– Headache
– Ringing in the ears (tinnitus) or hearing loss
– Difficulty focusing or seeing clearly
These symptoms can range from mild to severe and may last anywhere from a few seconds to several hours or even days.
How Vertigo Symptoms Differ in the Elderly
While vertigo can cause similar symptoms in people of all ages, older adults may experience them differently. For example, elderly patients tend to report less rotatory vertigo (the classic spinning sensation) and more non-specific dizziness and instability compared to younger patients.
Additionally, older adults with vertigo may have a higher risk of falls due to age-related changes in balance, muscle strength, and reaction time. Falls can lead to serious injuries, such as fractures, head trauma, and even death, making vertigo a significant concern for the elderly population.
Causes of Vertigo in the Elderly

Vertigo in older adults can be caused by various factors, ranging from inner ear disorders to neurological conditions. Some of the most common causes include:
Benign Paroxysmal Positional Vertigo (BPPV)
BPPV is the most common cause of vertigo in the elderly, accounting for approximately 50% of cases in those aged 70 or above. It occurs when tiny calcium crystals (otoconia) become dislodged from their normal location in the inner ear and migrate into the fluid-filled semicircular canals. This disrupts the normal flow of fluids and sends false signals to the brain, causing brief episodes of intense vertigo triggered by specific head movements.
Vestibular Neuritis and Labyrinthitis
Vestibular neuritis is an inflammation of the vestibular nerve, often caused by a viral infection. Labyrinthitis is a similar condition that also involves inflammation of the inner ear (labyrinth). Both conditions can cause sudden, severe vertigo lasting several days, often accompanied by nausea, vomiting, and balance problems.
Meniere’s Disease
Meniere’s disease is an inner ear disorder characterized by episodes of vertigo, fluctuating hearing loss, tinnitus, and a feeling of fullness in the ear. It is more prevalent in those above age 50. The exact cause is unknown, but it is thought to involve a buildup of fluid in the inner ear.
Age-Related Changes
As we age, various systems involved in maintaining balance, including the vestibular, visual, and proprioceptive systems, begin to decline. This natural deterioration, sometimes referred to as presbystasis or multisensory dizziness, can contribute to vertigo and instability in older adults.
Other Causes
Other potential causes of vertigo in the elderly include:
– Stroke or transient ischemic attack (TIA)
– Brain tumors
– Multiple sclerosis
– Migraine headaches
– Cervical spondylosis (arthritis of the neck)
– Medication side effects
Diagnosing Vertigo in the Elderly
Diagnosing vertigo in older adults can be challenging, as the symptoms may be vague, inconsistent, or attributed to other age-related conditions. A comprehensive evaluation by a healthcare professional, often an otolaryngologist (ENT) or neurologist, is essential for accurate diagnosis and treatment.
The diagnostic process typically involves:
- Thorough medical history, including a description of symptoms and any precipitating factors
- Physical examination, focusing on the ears, eyes, and neurological function
- Specialized tests, such as:
– Dix-Hallpike maneuver to assess for BPPV
– Vestibular function tests (e.g., electronystagmography, rotary chair test)
– Hearing tests (audiometry)
– Imaging studies (MRI or CT scan) to rule out central causes
Treating Vertigo in the Elderly

Treatment for vertigo in older adults depends on the underlying cause and may involve a combination of approaches:
Vestibular Rehabilitation
Vestibular rehabilitation therapy (VRT) is a specialized form of physical therapy that helps the brain adapt to vestibular dysfunction. It involves exercises designed to improve balance, reduce dizziness, and promote central compensation. VRT is often recommended for older adults with persistent vertigo, as it can help reduce symptoms and improve quality of life.
Canalith Repositioning Maneuvers
For BPPV, canalith repositioning maneuvers, such as the Epley maneuver, can be highly effective. These maneuvers involve specific head and body movements that guide the displaced otoconia back into their proper location in the inner ear. A trained healthcare professional can perform these maneuvers in the office, and patients can also learn to do them at home.
Medications
While medications do not cure vertigo, they can help manage symptoms in the short term. Common medications used for vertigo include:
– Antihistamines (e.g., meclizine, dimenhydrinate)
– Benzodiazepines (e.g., diazepam, lorazepam)
– Anticholinergics (e.g., scopolamine)
However, these medications should be used cautiously in older adults, as they can cause side effects such as drowsiness, confusion, and increased risk of falls.
Lifestyle Modifications
In addition to medical treatments, lifestyle changes can help manage vertigo symptoms in the elderly:
– Staying hydrated
– Getting enough sleep
– Managing stress and anxiety
– Avoiding sudden head movements or positions that trigger vertigo
– Using assistive devices (e.g., cane, walker) to improve stability and reduce fall risk
Conclusion
Vertigo is a common and often debilitating condition among older adults, with various potential causes ranging from benign inner ear disorders to more serious neurological conditions. Recognizing the unique presentation of vertigo symptoms in the elderly and understanding the age-related factors that contribute to its development is crucial for accurate diagnosis and effective treatment.
By working closely with healthcare professionals and utilizing a combination of vestibular rehabilitation, repositioning maneuvers, medications, and lifestyle modifications, older adults with vertigo can find relief from their symptoms and improve their overall quality of life. It is essential for both patients and caregivers to be aware of the increased risk of falls associated with vertigo in the elderly and to take appropriate precautions to ensure safety and prevent injuries.
If you or a loved one is experiencing vertigo or dizziness, don’t hesitate to seek medical attention. With proper care and management, it is possible to successfully navigate the challenges of vertigo and maintain an active, fulfilling life in your golden years.
