Psoriasis is a life-long skin condition, for which there is no cure, in which skin cells reproduce at a faster rate.

The skin cells accumulate (build up) and cause raised plaques (patches) to form. These patches can be red, (on Caucasian skin) or dark (on darker skin tones) flaky, itchy and scaly.

Psoriasis can occur anywhere on the body and can vary in degree and severity. Some people can go for long periods of time without a flare up of their psoriasis whilst other people may experience regular flare ups.

Psoriasis is a condition that affects a person physically and psychologically and has also been associated with other conditions. When people are provided with appropriate advice and treatment psoriasis can be well managed.

One of the aims of the GPA is to understand the number of people who are affected by psoriasis globally and what care and treatment is available to them wherever they live.

Although psoriasis is most often considered to be a physical condition, it can affect many areas of a person’s life, including their family, relationships, work, lifestyles, behaviour and mood.

Looking after mental well-being is important for everyone. We can all experience low mood at times in our lives and this is normal. However, sadness, anxiety, depression, anger and shame are all feelings that have been reported by people with psoriasis. Some people also report poor self-esteem and low self-worth, which can sometimes lead to social isolation.

It is important that people with psoriasis get advice from a doctor (ideally a dermatologist) to make sure they receive the correct diagnosis. In order to treat psoriasis successfully, a dermatologist and a psychologist may need to work together to develop a treatment plan which takes account of physical and psychological health, enabling people with psoriasis to achieve the best possible outcome.
