What Puts You at Risk for Alopecia Areata?
Published: May 22, 2024
Alopecia areata can appear out of the blue, but certain factors might increase your risk. Let's explore what these are.
Genetic Predisposition
Family history plays a significant role in the development of alopecia areata. Studies reveal that about 20% of people with alopecia have a first-degree relative with the condition. Twin studies also show a higher concordance rate in identical twins compared to fraternal twins.
Environmental Triggers
Infections, stress, and even certain vaccinations are thought to trigger episodes of alopecia areata. While many patients report severe emotional stress before episodes, others have no such history. Childhood trauma has also been suggested as a factor in adult cases.
Associated Autoimmune Conditions
Alopecia areata is often linked with other autoimmune disorders like thyroid disease and vitiligo. The presence of these conditions might indicate a higher risk for developing alopecia areata. Autoimmune thyroid disease is particularly noted for its association.
