Neurodermatitis

Neurodermatitis, or Local Scratch Dermatitis as it is sometimes call is a term used to describe several common forms of eczema. Lichen Simplex Chronicus is one type of eczema often referred to as neurodermatitis. It appears to be more prevalent in women, Asians and Native Americans -- and usually occurs between the ages of 25 – 50.

Symptoms

The primary symptom is a repeating itch-scratch-itch-scratch cycle, often just a single patch (i.e. the term “localized”) on the neck, forearm, thigh, wrist or ankle. Usually, this cycle of itching and scratching will come and go. Anxiety and/or stress may worsen the symptoms. Over time, due to the incessant scratching, the skin can become rough – with a leathery or scaly texture and appearance.

Causes

The cause in most cases is not known. However, scratch dermatitis can sometimes start with just very minor skin irritations, such as tight clothing, or a bug bite. The condition might also be attributed to extreme emotional stress or anxiety. Sometimes another skin condition, such as Contact Dermatitis or a parasitic infestation is the culprit.

Whatever the cause, once the scratching starts, the result is more intense itching – which leads to more scratching. Hence, the beginnings of a repeating itch-scratch cycle.

Normally, OTC (non-prescription) anti-itch creams will take care of the problem. Hydrocortisone (1%) may be sufficient to reduce the urge to itch, and allow the skin time to repair from the superficial damage caused by intense scratching. You can also try taking OTC antihistamines (i.e. Benadryl) to help reduce itching intensity.

In more stubborn cases, a doctor may prescribe oral corticosteroids and/or antihistamines. If anxiety or stress is deemed to play a role, anti-depressants or anti-anxiety medications may be helpful.

After the itching and scratching subsides, it can take several months for the skin to heal. In some cases, skin discoloration may remain long after the itching has stopped.
