A brain aneurysm is a life-threatening medical condition that occurs when a weakened section of a blood vessel in the brain balloons out and fills with blood. They can range from small to large, but all of them can be very dangerous if left untreated. A ruptured aneurysm can lead to severe complications such as stroke, neurological damage, and even death.
Every year, over 6 million people worldwide suffer from a brain aneurysm, with approximately 30,000 deaths due to this condition. They are most common in adults aged 35-60. Early detection of these aneurysms is critical for successful treatment and increased survival rates. Symptoms may include numbness or weakness in certain areas of the body, vision changes, vomiting or nausea, headache, confusion and seizures. A CT scan or magnetic resonance imaging (MRI) scan may be used to diagnose a potential aneurysm.
15 Main Causes to Know
The exact cause of most brain aneurysms is unknown, but there are some factors that increase a person’s risk for developing them. Having certain inherited conditions such as polycystic kidney disease, cerebral arteriovenous malformations (AVMs) or genetic connective tissue disorders can increase one’s likelihood for having an aneurysm. Additionally, having a following risk factor over time can weaken them and lead to a rupture.
As people age, their risk of developing a brain aneurysm increases significantly. It is believed that increased age contributes to these weakening vessels due to the wear and tear on them over time, leading to deterioration in structure.
Older age is one of many risk factors for the development of a brain aneurysm. If left untreated, a brain aneurysm can cause serious health issues including stroke or even death.
