Giant Cell Arteritis (GCA), also known as temporal arteritis, is a serious condition that causes inflammation of the blood vessels, particularly the arteries in the head. This guide provides a detailed overview of GCA, including its definitions, causes, symptoms, diagnosis, treatments, and more, all explained in simple language to help you understand this condition better.
Giant Cell Arteritis is an inflammation of the lining of the arteries, primarily affecting the large and medium-sized arteries in the head, especially those around the temples. It is more common in older adults, typically those over 50. If left untreated, GCA can lead to serious complications like vision loss.
Key Points:
- Also Known As: Temporal arteritis
- Affected Population: Mainly people over 50
- Primary Impact: Arteries in the head and temples
- Serious Complications: Vision loss, stroke
Pathophysiology
Understanding how Giant Cell Arteritis affects the body involves looking at the structure of arteries, blood flow, and nerve supply.
Structure
Arteries are blood vessels that carry oxygen-rich blood from the heart to various parts of the body. In GCA, the walls of these arteries become inflamed and thickened, which can restrict blood flow.
Blood Supply
GCA primarily affects the arteries in the head, especially the temporal arteries located near the temples. This inflammation can reduce blood flow, leading to symptoms like headaches and vision problems.
Nerve Supply
The inflammation can affect nerves near the arteries, causing pain, especially in the temples and scalp. This nerve involvement is why headaches are a common symptom.
Types of Giant Cell Arteritis
GCA can be categorized based on the arteries affected and the severity of the condition.
- Classic Temporal Arteritis: Involves the temporal arteries and is the most common type.
- Large Vessel Arteritis: Affects larger arteries like the aorta and its major branches.
- Polymyalgia Rheumatica-Associated GCA: Occurs alongside polymyalgia rheumatica, causing muscle pain and stiffness.
Causes of Giant Cell Arteritis
While the exact cause of GCA is unknown, several factors may contribute to its development. Here are 20 potential causes and risk factors:
- Age: Most common in individuals over 50.
