Overview

Polymyalgia Rheumatica
Polymyalgia rheumatica is an inflammatory disorder that causes pain and stiffness, especially in the shoulders, neck, and hips. Symptoms are often worse in the morning or after periods of rest. It mainly affects adults over 50 and may occur together with giant cell arteritis, which can cause headaches, vision problems, and other vascular symptoms.
Alopecia Areata
Alopecia areata is an autoimmune condition that causes the immune system to attack hair follicles, resulting in hair loss. It commonly produces one or more smooth, round patches of hair loss on the scalp or other areas of the body, although more extensive forms can affect much of the scalp or all body hair. Hair may regrow spontaneously, but the course is unpredictable and repeated episodes can occur. Changes to the nails may accompany more extensive disease.

Diagnosis

Polymyalgia Rheumatica
Polymyalgia rheumatica is diagnosed from the pattern of pain and stiffness, medical history, and physical examination. There is no single test that confirms the condition. Blood tests such as erythrocyte sedimentation rate and C-reactive protein may show inflammation. Additional testing may be used to exclude rheumatoid arthritis, other inflammatory disorders, infections, or malignancy.
Alopecia Areata
Alopecia areata is generally diagnosed through examination of the pattern of hair loss and the scalp, together with medical and family history. Dermoscopy can reveal characteristic changes in affected follicles. A scalp biopsy may be considered when the diagnosis is uncertain. Blood tests can be useful when there are signs of associated autoimmune, thyroid, nutritional, or other conditions. The clinician also considers other causes of patchy hair loss, including fungal infection and scarring disorders.

Prevention

Polymyalgia Rheumatica
There is no known way to prevent polymyalgia rheumatica. Because the condition is associated with giant cell arteritis, people diagnosed with PMR should be aware of new headaches, scalp tenderness, jaw pain while chewing, or visual changes and seek prompt medical evaluation if these occur. Regular follow-up can help monitor symptoms and treatment-related complications.
Alopecia Areata
There is no proven way to prevent alopecia areata because its autoimmune triggers are not fully understood. Maintaining general health and managing associated autoimmune conditions can support overall well-being but cannot guarantee prevention. People with sudden patchy hair loss should seek evaluation because some causes are treatable and early diagnosis can guide management. Avoiding unnecessary scalp trauma or harsh hair treatments can reduce additional hair damage, although these practices do not prevent the autoimmune process.

Risk Factors

Polymyalgia Rheumatica
Polymyalgia rheumatica occurs almost exclusively in adults over 50 and is more common in women. Risk may also be influenced by genetic and geographic factors. Having giant cell arteritis is closely associated with PMR, and people with PMR may develop symptoms of giant cell arteritis. There are no established lifestyle measures known to prevent the disorder.
Alopecia Areata
Risk factors for alopecia areata include a family history of the condition and a personal or family history of autoimmune disease. It can occur at any age but often begins earlier in life. Certain immune-related conditions may increase susceptibility. The presence of a risk factor does not predict how extensive hair loss will become. Some people develop alopecia areata without any known risk factor.
