Final answer:
It is true that 40% of psoriasis patients have a family history, indicating a genetic predisposition. Psoriasis involves an accelerated cell turnover leading to characteristic skin patches and can lead to psoriatic arthritis.
Step-by-step explanation:
The statement that 40% of patients with psoriasis have a family history can be considered true as numerous studies indicate a significant genetic link in the development of psoriasis. Having a family member with psoriasis increases an individual's risk of developing the condition. Psoriasis is an inflammatory skin disease characterized by rapid cell turnover, leading to thick, red skin with silvery scales. It can also lead to psoriatic arthritis, causing joint inflammation in some cases.
Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. It is characterized by a fast turnover of skin cells due to cytokine activation, resulting in the thick inflamed patches of skin.
According to the provided information, 40% of patients with psoriasis have a family history. This means that a significant proportion of individuals with psoriasis have a genetic predisposition to the disease.
