"atopic dermatitis"の定義と意味

What is "atopic dermatitis"?

Atopic dermatitis, often called eczema, is a chronic skin condition characterized by dry, itchy, and irritated patches of skin. It commonly affects areas like the face, elbows, knees, and hands, but it can occur anywhere on the body. Atopic dermatitis is believed to be caused by a combination of genetic and environmental factors, such as allergens, irritants, and immune system dysfunction. Symptoms can vary from mild to severe and may include redness, swelling, crusting, and oozing of the affected skin. Treatment typically involves moisturizing the skin, avoiding triggers, using skin creams or ointments to reduce inflammation, and managing itching to prevent scratching and further irritation.
