A fairly atypical clinical case. An Australian man in his 60s was recently forced to go to the emergency room with nausea, dizziness and blurred vision caused by a brain hemorrhage. The reason for this hemorrhage? A visit to the dentist, a few minutes earlier, teaches us Science en direct. We will explain it to you.

Dizziness, nausea and vision problems
He described his symptoms to hospital staff: dizziness, nausea and vomiting, as well as vision problems. He says he perceives the environment with a 90° tilt to the left. Doctors notice high blood pressure, abnormal eye movements, and a tendency to lean to the right when walking. Signs of intracerebral hemorrhage. A diagnosis that is confirmed by imaging tests.
What is a brain hemorrhage?
A brain hemorrhageis a bleeding that occurs suddenly, by rupture of a small vessel, creating a hematoma inside the brain itself», Specifies the Saint-Joseph hospital, in Paris, on its website. These bleedings can also be the cause of so-called “hemorrhagic” strokes, which are rarer than cerebral infarctions or ischemic strokes.
“The main cause of hemorrhagic strokes is high blood pressure (hypertension or hypertension).», notes the Health Insurance platform Ameli.fr. Other factors can also cause cerebral hemorrhage, such as cerebral vascular malformations, coagulation disorders, cerebral amyloid angiopathy, brain tumors, venous thrombosis disorders or even alcoholism, lists the Stroke Research Foundation. Smoking, cholesterol and age are also identified risk factors.
A rare underlying pathology
The Australian patient was indeed suffering from hypertension when he arrived at the hospital. Doctors then quickly make the link with the dental appointment preceding the appearance of symptoms. They believe the sudden increase in the patient’s blood pressure was triggered by pain or stress from the dental procedure. Although rare, similar cases have already been reported in the scientific literature. In this type of situation, high blood pressure then acts as a “detonator” in people who already have vascular fragilities.
Six weeks before his brain hemorrhage, the patient had also seen a specialist for warning signs of Parkinson’s disease. Examinations carried out on this occasion showed a reduction in blood flow in certain parts of his brain. Genetic testing after his stroke revealed a mutation associated with CADASIL, a rare genetic disorder that thickens the walls of blood vessels and reduces their ability to carry blood to the brain. This pathology, which affects approximately two people in 100,000, is known to promote strokes, particularly hemorrhagic ones.
After receiving emergency treatment to stop the bleeding, the patient was placed on antihypertensive medication and aspirin, to facilitate blood circulation in the future. Three months after his release from the hospital, his vision and balance had improved.
