When people think about a stroke, many imagine sudden paralysis, facial drooping, and/or trouble speaking. However, other symptoms are often experienced and problematic — persistent vertigo and dizziness. These sensations are described as spinning (of the person or the environment), imbalance, or lightheadedness, and can linger for months or even years. This study demonstrates that vertigo and dizziness are common after stroke, have a negative effect on daily living, and are not specifically addressed by current stroke care.
Why This Study Was Done
Stroke survivors often have lingering symptoms that make life harder, even after doctors have treated the immediate medical emergency. Researchers indicate that long-term quality of life after stroke can be lower than expected, and that most post-stroke care focuses on things like physical weakness or language problems. Vertigo and dizziness — which are subjective symptoms that people report themselves — haven’t been systematically studied in large groups of stroke survivors.
The researchers set out to analyze the impact of vertigo and dizziness in a large group of stroke survivors over the course of one year, and to answer the following questions:
- How do these symptoms affect a person’s quality of life?
- Are there associations with comorbidities and risk factors?
- What are the symptom frequency and durations?
- What is the relationship between current rehabilitation participation and ongoing symptoms?
Ultimately, the understanding of post-stroke vertigo and dizziness could potentially support the need for comprehensive assessments to assist in addressing these symptoms.
Who Took Part In This Study
The study looked at nearly 1,800 adults who were admitted to a hospital in Augsburg, Germany, after having a stroke or a “mini-stroke” (TIA). These participants were first evaluated in the hospital and then followed up at 3 months and 12 months after their stroke. About 55 % of participants completed the 12-month follow-up. It was that 12-month follow-up which was analyzed in detail.
Among those who completed the follow-up, around 41% reported chronic vertigo or dizziness at one year after their stroke. That means four in ten stroke survivors were still struggling with these symptoms long after hospital treatment.
What “Vertigo” and “Dizziness” Mean in This Study
In this research, vertigo was defined as the sensation of rotational movement or rocking/swaying, like the room or the individual is moving when it shouldn’t be. Dizziness was described as lightheadedness or imbalance while walking. The study described symptoms as chronic at the 12-month mark, regardless of frequency (constant or intermittent).
Impact on Quality of Life
To measure quality of life, the researchers used a stroke-specific tool called the Stroke Impact Scale (SIS). This scale includes many different categories, most noteworthy:
- Participation in social or work activities
- Mobility and balance
- Memory and thinking
- Everyday function and independence
After adjusting for age, sex, stroke severity, and other health conditions, the study found that people with vertigo or dizziness scored significantly lower across multiple quality-of-life domains compared to those without these symptoms.
Some of the biggest impacts were seen in:
- Participation: People with new-onset vertigo or dizziness struggled more to return to social life, work, and activities they used to enjoy.
- Mobility: Those who already had vertigo or dizziness before their stroke were particularly affected in their ability to walk or move confidently.
- Memory and Thinking: People who couldn’t clearly identify when their symptoms started tended to have more trouble with memory and thinking.
The Bottom Line
Chronic vertigo and dizziness aren’t just occasional annoyances post-stroke — these symptoms clearly make it harder for people to re-engage with life, walk safely, work, and think clearly. Even though rehabilitation is available, it may not specifically address these symptoms, resulting in a lower quality of life.
Rehabilitation and Treatment Participation
People who developed vertigo or dizziness after a stroke were more likely to take part in rehabilitation programs compared with survivors who did not report these symptoms. Yet despite greater participation, they actually had worse outcomes in quality-of-life measures. This suggests that current rehabilitation programs may not adequately target the specific challenges associated with dizziness and vertigo.
Why These Symptoms May Persist
Vertigo and dizziness after a stroke can have many causes. In some cases, a stroke damages parts of the brain that help control balance and eye movement coordination. Symptoms may also be worsened by:
- Cardiovascular issues (like blood pressure changes or arrhythmias)
- Visual problems
- Anxiety or psychiatric conditions
- Small vessel disease in the brain
- Peripheral nervous system dysfunction
The complex nature of it all makes it hard to treat vertigo and dizziness with a single approach, especially since balance tests don’t always reflect how severe the symptoms feel to a patient.
What This Means for Stroke Care
The big takeaway from this study is that vertigo and dizziness are common and persistent post-stroke symptoms that significantly affect quality of life AND are often overlooked in standard care plans. The authors argue that stroke recovery should include:
- Systematic screening for vertigo and dizziness
- Careful clinical evaluation to understand potential causes
- Multidisciplinary rehabilitation approaches, including physical and vestibular therapy, tailored to these symptoms
Addressing these issues earlier, with a standardized, comprehensive approach, could help stroke survivors improve their quality of life and optimize their return to meaningful activities.
