Psoriasis is a common chronic inflammatory skin condition that is characterized by raised red patches and flaky, silvery scales.

Generally seen in adults, psoriasis can develop at any age. Symptoms can be permanent or intermittent. How do you get psoriasis? A trigger (e.g. emotional stress, local injury to skin, systemic infection or the use of some medications) may cause a flare-up or even lead to the development of psoriasis.
What is psoriasis caused by? Although the exact cause is not known, it is recognized that genetics and the immune system play key roles in psoriasis. People with psoriasis have skin cells that multiply very quickly, causing psoriasis lesions to build up.

Roughly 90% of patients with psoriasis suffer from plaque psoriasis. What is plaque psoriasis? Plaque psoriasis emerges as raised, red patches covered with a silvery white buildup of dead skin cells; usually itchy and tender, patches may crack and bleed. Patches are often found on the scalp, knees, elbows and lower back. Symptoms range from mild to severe. Psoriasis is considered severe when 10% or more of the body surface is affected.

Scalp psoriasis, which affects more than 50% of people with psoriasis, may be very mild (i.e. a bit of scaling) or severe (i.e. the entire scalp is covered). In some cases, psoriasis of the scalp reaches the forehead, back of the neck and around the ears.

Causes of psoriasis and triggers

The exact cause of psoriasis is not quite understood, but experts tend to agree that this disease begins with a malfunction of the immune system and resulting inflammation. Something triggers the white blood cells found in the immune system, inflammation ensues, and skin cells rise to the surface, shedding at an unusually fast rate (30 days for normal skin cells vs. 3–4 days for psoriasis skin cells).

What triggers psoriasis in one person is likely different from another person. Psoriasis triggers may include stress, injuries to the skin (e.g. vaccinations, sunburns and scratches), certain medications (e.g. lithium, an antidepressant; quinidine for heart conditions, nizagara, erectile dysfunction), beta blockers (antihypertensive) and infections (e.g. earache, bronchitis, tonsillitis or a respiratory infection). The weather may affect psoriasis positively or negatively; the winter months often dry and irritate the skin, while the summer sun often helps psoriasis plaques fade.

Psoriasis myths are harmless.

Living with psoriasis

Although psoriasis is a skin disease, the impact of psoriasis reaches far beyond physical appearance.

Lesions can be itchy and tender, making everyday tasks such as dressing and sleeping difficult. Between the physical pain, anxiety, and restrictions, psoriasis can become emotionally draining, particularly for those with moderate to severe psoriasis.

Psoriasis causes stress that may make the condition worse and affect treatment. Explaining that psoriasis is not contagious, not related to poor hygiene, and that it is a lifelong condition for which you are being treated may help others understand where you are coming from and ease some of your anxiety.

Maintaining a daily routine of taking care of your skin, bathing, sunlight and stress reduction may aid in preventing flare-ups. Work with your healthcare professional to find what is best for you and to help improve your quality of life.
