The analysis found: Participants who reported a previous COVID-19 infection were 9.7 times as likely to have rapid abdominal aortic aneurysm growth (higher growth than the average of 2.7 mm per year).
In this paper, we report two cases of ruptured vertebral artery dissecting aneurysm (VADA) immediately after messenger RNA (mRNA) anti-COVID-19 vaccination. In Case 1, a 60-year-old woman experienced sudden headache 3 weeks before her first dose of the Moderna mRNA-1273 COVID-19 vaccine.
Overall, incidence increased by 0.7% on average per year, rising 1.1% in middle-aged men, 2.3% in in older men and 0.7% in older women, the study showed.
[5,8,28] In addition, small peripheral arteries are more susceptible to vascular injury than the thick-walled main arteries of the brain, which may explain why SAH caused by COVID-19 infection is more common in cortical areas. Some COVID-19 patients also had multiple cerebral infarctions.
Brain aneurysms may be found during imaging tests that are done for other conditions. However, a ruptured aneurysm is a very serious condition, typically causing a severe headache. And if an unruptured aneurysm presses against brain tissue or nerves, it may cause pain and other symptoms.
Causes of aneurysms
high blood pressure (hypertension) over many years resulting in damage and weakening of blood vessels. fatty plaques (atherosclerosis) resulting in a weakness of the blood vessel wall. inherited diseases that may result in weaker than normal blood vessel walls.
They are most common in adults between the ages of 30 and 60 and are more common in women than in men. People with certain inherited disorders are also at higher risk. Sometimes cerebral aneurysms are the result of inherited risk factors, including: genetic connective tissue disorders that weaken artery walls.
When people first become sick from the virus, they may develop encephalitis — inflammation of the brain — causing confusion, difficulty concentrating, and memory problems. COVID also can trigger the onset of new psychological disorders such as severe depression or anxiety.
Recent research shows physical changes in the brain from COVID-19. In a study published earlier this year, scientists in the United Kingdom studied people who had COVID-19 and found evidence of decreased brain size, tissue damage and a decrease in grey matter (the brain's outer tissue which is vital to brain function).
How does COVID-19 affect the blood? Some people with COVID-19 develop abnormal blood clots, including in the smallest blood vessels. The clots may also form in multiple places in the body, including in the lungs. This unusual clotting may cause different complications, including organ damage, heart attack and stroke.
A severe headache that comes out of nowhere (often described as the worst headache one has ever felt) Blurred vision. Feeling nauseated. Throwing up.
On average, patients who underwent repair for a ruptured aneurysm lived 5.4 years after surgery. Researchers found no significant differences in relative five-year survival rates between men and women or between age groups. However, researchers found differences in the repair of intact aneurysms.
One of the most obvious signs of a ruptured aneurysm is intense head pain, typically described as the worst headache of your life. Additional symptoms of a ruptured aneurysm include: Nausea and vomiting. Double or blurred vision.
To our knowledge, ten cases of intracranial hemorrhage after the Pfizer-BioNTech COVID-19 mRNA (BNT162b2) vaccine have been reported in the literature across four different studies [3,6-8]. In one case, ruptured arteriovenous malformation caused intracranial hemorrhage [3].
Vascular complications in the brain
Due to the activity of the immune system, after the injection of COVID-19 vaccines, especially adenovirus-based type, thrombocytopenia, cerebral venous sinus thrombosis, ischemic stroke and intracerebral hemorrhage, have also been reported [27].
So far, there have been multiple reports of trigeminal neuralgia developing after COVID-19 vaccination.
How long does brain fog last after COVID-19 is treated? The good news is that the vast majority of patients with post-COVID-19 brain fog recover completely over the course of 6 to 9 months.
Blood clots in the arteries leading to the brain can cause a stroke. Some previously young, healthy people who have developed COVID-19 have suffered strokes, possibly due to abnormal blood clotting.
Research has found that though the COVID-19 virus largely affects the lungs, other organs can be damaged by it as well. Most of the damage scientists have seen so far has been concentrated to the heart, lungs, and brain, including damage to the heart muscle, scar tissue in the lungs, and strokes and seizures.
Strong emotions, such as being upset or angry, can raise blood pressure and can subsequently cause aneurysms to rupture.
Unruptured brain aneurysms affect 2% to 5% of healthy people, and about 25% of them have multiple aneurysms. Most brain aneurysms develop in adulthood, but they can also occur in children with mean age of detection around 50 years.
In a study of about 70,000 adults, researchers found that people with a genetic predisposition to insomnia were at somewhat higher risk of a brain aneurysm. An aneurysm is a weak spot in an artery wall that bulges out and fills with blood. In some cases, it can rupture and cause life-threatening bleeding.
