Atherosclerosis and Brain Aneurysms
Atherosclerosis occurs when plaque accumulates in arteries, which can be particularly dangerous if it affects those supplying the brain. Maintaining low cholesterol levels is essential to prevent issues such as aneurysms.
What exactly is atherosclerosis?
Atherosclerosis occurs when plaque accumulates on artery walls, causing them to stiffen and narrow, which reduces blood flow. It is often caused by high cholesterol and can affect brain arteries, potentially leading to strokes or aneurysms.
How Atherosclerosis Leads to Aneurysm Formation
Atherosclerosis and aneurysms are connected because plaque buildup strains artery walls. Excess plaque can weaken arteries, causing them to bulge or rupture as aneurysms. Monitoring cholesterol levels is essential to prevent these issues.
| Factor | Description | Impact |
|---|---|---|
| Cholesterol Levels | High levels of LDL cholesterol contribute to plaque buildup. | Increased plaque can lead to more significant artery blockages and potential aneurysm development. |
| Arterial Wall Strength | Plaque weakens artery walls over time. | Weakened walls are more likely to form aneurysms under stress. |
| Blood Flow Restriction | Blockages reduce the flow of blood to vital organs. | Reduced blood flow to the brain can precipitate severe health events, including aneurysms. |
Age and Gender as Risk Factors
