Alopecia areata
This autoimmune disorder affects approximately 2% of the general population and is characterized by transient, non-scarring hair loss with preserved hair follicle. Authors from USA describe the current knowledge on the epidemiology of alopecia areata from a global perspective. The onset of this pathology might be at any age, but most patients develop the condition before the age of 40. Numerous studies support that alopecia areata has a genetic basis and is associated with several comorbidities including depression, anxiety, and autoimmune disorders (thyroid disease, lupus erythematosus, vitiligo, psoriasis, rheumatoid arthritis). Diagnostics is often based on clinical manifestations, but dermoscopy and histopathology are recommended for verification. Get more details by the link!
