Psoriasis, an enduring autoimmune condition, prompts accelerated skin cell growth, leading to the formation of thick, scaly patches on the skin. While non-contagious, psoriasis can cause discomfort and contribute to other skin complications like infections.

The onset of psoriasis typically occurs between ages 15 and 35, though it can manifest at any age. While not communicable, psoriasis may have a genetic component, often running in families.

Causes

• Infections from bacteria or viruses, such as strep throat and upper respiratory infections
• Dry air or dry skin
• Skin injuries, including cuts, burns, insect bites, and other skin rashes
• Certain medications, like antimalarial drugs, beta-blockers, and lithium
• Stress
• Inadequate sunlight exposure
• Excessive sunlight exposure leading to sunburn

Symptoms

Symptoms of psoriasis can manifest suddenly or develop gradually, often recurring over time. The primary indication of the condition is the presence of irritated, red, and flaky patches of skin known as plaques. These plaques commonly appear on areas like the elbows, knees, and torso, although they can emerge anywhere on the body, including the scalp, palms, soles of the feet, and genital area.

Characteristic features of psoriatic skin include:

• Itchiness
• Dryness accompanied by silver, flaky scales
• Pink-red discoloration
• Raised and thickened skin

Additional symptoms may include:

• Joint or tendon pain and stiffness
• Nail abnormalities, such as thickened, discolored, or pitted nails, and separation of the nail from the underlying skin
• Severe dandruff affecting the scalp

These symptoms vary in severity and may significantly impact an individual's quality of life.
