Psoriasis Symptoms
Scalp Psoriasis
Psoriasis is a chronic condition that currently affects about four million Americans. It is a disease in which the regeneration of skin cells occurs at an extremely rapid rate. This becomes compounded by the fact that the skin in affected areas does not slough off easily. Therefore, the result is patches of scaly, swollen lesions that are itchy and may even be painful. Psoriasis can occur on any area of the body, but it is most often found on the elbows, knees, legs, palms, feet, and face. It can also affect the area on and around the scalp. Scalp psoriasis affects roughly two to three percent of the population nationwide.
Psoriasis Causes
Approximately one-third of the people who are diagnosed with psoriasis have one or more family members with the condition. Yet it is unclear if genetic factors alone determine the propensity for psoriasis. Many doctors also believe that other factors, such as certain immune response and environmental conditions may play a role in the development of the disease. Other factors that may cause or aggravate psoriasis include climate, skin injuries, stress, infections, or a reaction to certain medications.
Symptoms of Psoriasis
The classic symptoms of psoriasis includes swollen, red patches of skin, or lesions, that are covered with loose, silvery scales. Psoriasis most frequently occurs on the knees and elbows, although it can appear on the skin anywhere throughout the body.
