Alopecia areata: causes, symptoms and treatment

Alopecia areata, also known as alopecia areata or alopecia areata, is a form of baldness that appears as round or oval areas of baldness on the scalp or other parts of the body.

The causes of alopecia areata are not fully understood, but it is thought to be an autoimmune disease where the immune system attacks the hair follicles, leading to their destruction. Genetic factors, stress, trauma, infectious diseases and other factors can also influence the appearance of alopecia areata.

Symptoms of alopecia areata include the appearance of round or oval areas of balding on the scalp or other parts of the body. Bald areas can vary in size and can join together to form larger bald areas. In most cases, alopecia areata is not accompanied by itching, pain or other symptoms.

Diagnosis of alopecia areata involves examining the scalp or other parts of the body and reviewing your medical history. If the diagnosis is unclear, a skin biopsy may be performed to determine the cause of the hair loss.

Treatment for alopecia areata may include the use of medications such as creams, lotions, or steroid injections in the balding area. Light therapy or immunotherapy may also be used. Some people choose to wear wigs or use other methods to cover up balding areas.

Although alopecia areata is not a dangerous disease and does not cause physical pain, it can have a strong psychological impact on people suffering from this condition. Therefore, it is important to see a doctor if you notice areas of balding on your scalp or other parts of your body. The doctor will be able to make a diagnosis and suggest the most effective treatment methods.

Alopecia areata, or alopecia focal (aareatae; synonym alopenia circular - areatum, circle; English orphan alopecia, orphrenia alopecia) is focal hair loss caused by a violation of the synthesis and secretion of sex hormones or a change in their reception; in this case, hair falls out of the hair follicles in nest-shaped, often circular, foci.

Alopecia areata is characterized as a manifestation of hair loss of secondary origin. Hair loss is not a primary symptom and occurs mainly at the site of inflammatory processes - furunculosis and pyoderma, after the use of corticosteroids internally and corticonase drugs externally, with cirrhosis of the liver and infectious mononucleosis, as well as with psychogenic disorders. This etiology of hair loss is confirmed by laboratory indicators.

Clinically, alopenia alopecia is differentiated from alopecia infantum. The disease is characterized by the occurrence of multiple foci of baldness and is found in familial form. On the skin there are erythematous areas with nests and nests up to 1 cm in size with a tendency to merge and form large foci. Hair falls out both from the back of the head and throughout the entire head area, on the eyebrows, above the upper lip.
