What are the symptoms of neurodermatitis?

Normally, neurodermatitis is a common chronic inflammatory skin condition that may be caused by various factors such as improper diet, unhealthy lifestyle habits, local irritation, and contact with allergens. Symptoms may include skin itching, lichenification, dry skin, papules, and hyperpigmentation. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

1. Skin Itching

This is a relatively typical and prominent symptom of neurodermatitis, which may be related to dysfunction of the nervous system. Long-term mental tension, anxiety, depression, and other negative emotions can cause nervous system dysfunction, leading to symptoms such as skin itching.

2. Lichenification

Due to prolonged scratching and inflammatory stimulation, skin tissue may proliferate and thicken, causing gradual lichenification. This表现为 skin thickening, deepened skin markings, elevated skin ridges, and the formation of polygonal flat papules with clear borders that coalesce into patches, resembling moss. This is the characteristic skin lesion of neurodermatitis.

3. Dry Skin

Neurodermatitis can damage the skin's barrier function, reducing its ability to retain moisture and increasing water loss through the epidermis. At the same time, nervous system dysfunction may affect the secretory functions of sebaceous and sweat glands, leading to reduced secretion of sebum and sweat, which cannot effectively moisturize the skin, thus making the skin dry and rough.

4. Papules

The appearance of this symptom may be due to immune system abnormalities. Under the influence of triggers such as psychological factors and local irritation, the immune system may mount an abnormal immune response against skin tissues, causing accelerated proliferation of skin cells and forming flat papules the size of pinheads to rice grains, which may appear pale red, normal skin color, or light brown.

5. Hyperpigmentation

During the chronic course of the disease, due to repeated scratching, inflammatory stimulation, and other reasons, the affected areas of skin may develop hyperpigmentation, with darkened color appearing light brown, dark brown, or black, making the skin look rougher and duller.

Patients with neurodermatitis are advised to keep the skin clean and dry in daily life, avoid excessive scratching and friction of the affected areas, which helps promote skin recovery.
