Overview

Neurodermatitis may be a skin condition that starts with an itchy patch of skin. Scratching makes it even itchier. This itch-scratch cycle causes the affected skin to become thick and leathery. You may develop several itchy spots, typically on the neck, wrists, forearms, legs or anal region.

Neurodermatitis — also referred to as lichen simplex chronicus — isn't life-threatening or contagious. But the itching are often so intense or recurrent that it disrupts your sleep, sexual function and quality of life.

Breaking the itch-scratch cycle of neurodermatitis is challenging, and neurodermatitis is typically a lifelong condition. Treatment success depends on resisting the urge to rub or scratch the affected areas. Over-the-counter or prescription medications may help ease the itching. You'll also need to identify and eliminate factors that may be aggravating the problem.

Symptoms

Signs and symptoms of neurodermatitis include:

Ø  An itchy skin patch or patches

Ø  Leathery or scaly texture on the affected areas

Ø  A raised, rough patch or patches that are red or darker than the rest of your skin

The condition involves areas that can be reached for scratching — the head, neck, wrists, forearms, ankles, vulva, scrotum or anus. The itchiness, which may be intense, may come and go or be n"art-13">You may cut out of habit and while sleeping.

When to see a doctor

See your doctor if:

Ø  You catch yourself repeatedly scratching the same patch of skin

Ø  The itch prevents you from sleeping or focusing on your daily routines

Ø  Your skin becomes painful or looks infected and you have a fever

Causes

The cause of neurodermatitis is unknown. The persistent rubbing and scratching that characterize the condition may begin with something that simply irritates the skin, like tight clothing or a bug bite. As you rub or scratch the world , it gets itchier. The more you scratch, the more it itches.

In some cases, neurodermatitis is related to chronic skin conditions — like dry skin, eczema or psoriasis. Stress and anxiety can trigger itching too.

Risk factors

Certain factors may affect your risk of neurodermatitis, including:

Ø    Your sex and age. Women are more likely to develop neurodermatitis than are men. The condition is commonest between ages 30 and 50.

Ø    Other skin conditions. People with a private or case history of dermatitis, eczema, psoriasis or similar skin conditions are more likely to develop neurodermatitis.

Ø    Anxiety disorders. Anxiety and stress can trigger the itch of neurodermatitis.
