Coronavirus (COVID-19) information for stroke survivors, neurology patients and caregivers
What is coronavirus (COVID-19)?
As many of you already know, the novel coronavirus or COVID-19 is an infectious disease that has now spread throughout the world. It is a respiratory infection that can range from mild, common cold symptoms like a cough to flu symptoms like fever or a sore throat. COVID-19 can also cause severe symptoms like breathing problems and respiratory arrest. We’ve also seen patients experience neurologic symptoms such as mild headaches, muscle aches and loss of senses such as smell and taste.
Are people with neurologic conditions at higher risk of contracting COVID-19?
We do know specific populations of patients with neurologic diseases are at a higher risk, including patients who are on immunotherapy. Medications that suppress your immune system, which are used to treat conditions like multiple sclerosis (MS), may make patients more vulnerable to contracting the coronavirus.
Patients who have neurologic conditions and are not on immune suppressant medications may also be more vulnerable because of their age and associated neurologic deficits, like stroke, Parkinson’s disease and dementia. These individuals and their caregivers need to be aware of potential exposures to COVID-19 and take extra precautions.
Are people who have survived a stroke at higher risk of contracting COVID-19?
In the data that has been published to date, we have seen that some patients with risk factors for stroke and heart disease, as well as those who have previously experienced a stroke, are at higher risk of serious complications of COVID-19, including death.
If you have had a stroke or are at risk for experiencing a stroke, take extra caution during this pandemic.
What should stroke and neurology patients do to stay safe and healthy during the COVID-19 pandemic?
The advice we’ve been giving the general public should be followed more strictly by stroke and neurology patients. That includes physical distancing, washing hands, cleaning surfaces and limiting time outside the home unless it is essential. We recommend neurology and stroke patients ask a family member or friend to make essential trips to the grocery store or pharmacy, as opposed to going out themselves.
The recent emphasis on universal masking is to prevent people who may be asymptomatic (not showing symptoms) from spreading any illness. We recommend our stroke and neurology patients wear masks at all times outside their homes. If you do not have a mask, the CDC offers a guide for how to make masks out of household items.
Should I keep taking my stroke medications? If I need to take a blood test or attend a checkup, how should I do that?
It is essential to keep taking your stroke medications, especially medications that control risk factors like blood pressure or diabetes, because the risk for stroke increases if you stop taking medications. When it comes to medications that require blood checks, such as Coumadin or Warfarin, talk to your doctor about the frequency with which you need to have your blood drawn so that you can maintain the appropriate INR levels.
Does COVID-19 affect the brain or cause other neurologic conditions?
There seem to be several levels of effects of the virus. In general, we have seen COVID-19 cause some mild neurologic conditions like headache, muscle aches, dizziness and even confusion. Early signs of the virus can also be loss of sense of smell or taste.
COVID-19 can also affect current neurologic patients such as those who have survived a stroke or have MS. If those patients contract the virus, they may experience a temporary worsening of their preexisting conditions. This is because most viruses and other acute conditions can make the brain weaker than it was before onset of the condition, but these symptoms are not necessarily permanent. It is important that the patient or their caregiver recognize any symptoms of coronavirus and contact their physician immediately. If the physician thinks the symptoms are a worsening of the baseline neurologic condition, they may request an assessment by phone or in person.
The last level of effect is the most unknown. Right now we only have small pieces of data that suggest it is possible for COVID-19 to directly infect the brain, causing conditions like meningitis and encephalitis. Although this has been rarely reported, it may be a possibility for those who are immunocompromised (weakened immune systems) and have a higher risk of infection.
Why is COVID-19 causing stroke/blood clots in young and middle aged people?
While there isn’t enough data to know exactly why COVID-19 may cause strokes in otherwise healthy young people, it may be related to three possible concepts. First, infections including COVID-19, trigger inflammation in the body. Inflammation may increase the chances of a clot forming in the blood and causing a stroke. Second, COVID-19 may cause some direct changes to the lining of the blood vessels, which can result in clot formation. Lastly, it has been shown that COVID-19 is associated with severe clotting resulting in stroke. It is not yet know if asymptomatic COVID-19 patients are experiencing these reactions in a milder form.
What are symptoms of stroke/blood clot?
A stroke occurs when blood supply to the brain is disrupted either by a clot blocking an artery or a rupture of an artery in the brain. Depending on the region of the brain that is affected, stroke symptoms vary. Typical symptoms are sudden weakness or numbness on one side of the body, difficulty speaking clearly, loss of vision, and loss of balance. Use the acronym F.A.S.T. to recognize symptoms of a stroke and know when to call 911.
- F – Face drooping
- Does one side of the face droop or is it numb? Ask the person to smile. Is the person’s smile uneven or lopsided?
- A – Arm weakness
- Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward?
- S – Speech difficulty
- Is speech slurred? Is the person unable to speak or hard to understand? Ask the person to repeat a simple sentence, like “The sky is blue.” Is the person able to correctly repeat the words?
- T – Time to call 911
- If someone shows any of these symptoms, even temporarily, call 911 for help. Don’t delay and also note the time when symptoms started so you can help emergency responders.
If you or a family member is having a stroke, it’s critical to get medical attention right away. Immediate treatment may minimize the long-term effects of a stroke and even prevent death.
What should I do if I am experiencing a stroke/blood clot?
The most important thing to do if you or a family member is experiencing a stroke is to call 911. The city of Chicago follows stroke protocol that ensures safe evaluation and management by paramedics who then take suspected stroke patients to the nearest certified stroke center hospital. The University of Chicago Medicine has two nationally recognized stroke centers, including our Joint Commission-certified Comprehensive Stroke Center in Hyde Park.
Even during this pandemic, UChicago Medicine has been serving our community and providing stroke care. If you think you are having a stroke, it is extremely important not to wait or avoid health care because you are concerned about COVID-19.
