Alopecia areata is a disease that happens when the immune system attacks hair follicles and causes hair loss. Hair follicles are the structures in skin that form hair. While hair can be lost from any part of the body, alopecia areata usually affects the head and face.
This is also called androgenetic alopecia. MedlinePlus identifies a number of additional medical conditions that may cause this type of hair loss. These include high blood pressure, heart disease, prostate cancer, and polycystic ovary syndrome (PCOS).
Alopecia is, simply put, hair loss. If you have alopecia, you might see extra hair on pillows or in shower drains, or you might notice bald patches on your scalp. Over time hair loss can grow back or fall out permanently, depending on the cause. Alopecia is not curable, but it's treatable and not life-threatening.
Alopecia areata is an autoimmune disease where your immune system attacks its own healthy hair follicles. Studies show that people with alopecia areata can have other autoimmune diseases, such as thyroid disease.
Alopecia areata is sometimes triggered by viral infections such as influenza that causes excess production of interferons (IFN). IFN- γ is one of the key factors that lead to the collapse of immune privilege.
A variety of factors are thought to cause alopecia areata (al-o-PEE-she-uh ar-e-A-tuh), possibly including severe stress. With alopecia areata, the body's immune system attacks the hair follicles — causing hair loss.
Both men and women tend to lose hair thickness and amount as they age. This type of baldness is not usually caused by a disease. It is related to aging, heredity, and changes in the hormone testosterone. Inherited, or pattern baldness, affects many more men than women.
How Long does Hair Loss Last? In half of patients with alopecia areata, individual episodes of hair loss last less than one year, and hair grows back without treatment. These patients may experience recurrent episodes of hair loss that spontaneously regrow or respond quickly to treatments.
Androgenic alopecia (AGA) is associated with significant cardiovascular risk factors that also have a negative impact on brain aging.
Compared with the general population, increased prevalence rates of psychiatric disorders are associated with alopecia (Koo et al., 1994) suggesting that people with alopecia may be at higher risk for development of a major depressive episode, anxiety disorder, social phobia or paranoid disorder.
There is no cure for AA. While treatments may promote hair growth, new patches of hair loss may continue to appear. The treatments are not a cure. Only the body, itself, can eventually turn off the condition.
Alopecia Areata.
Some people may experience hair loss in other parts of the body. Although the hair will grow back, continued anxiety and stress can cause the hair loss to continue leading to different patches of hair and baldness.
Alopecia areata (AA), an autoimmune disease that causes hair loss, including baldness, has been linked to a significantly increased risk for dementia, new research shows.
Alopecia areata can occur at any age but about half of cases come on in childhood and 80% of cases come on before the age of 40 years. Men and women are equally affected. The condition tends to be milder if it comes on at an older age.
The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30. Alopecia areata is not life-threatening and does not cause physical pain. However, the psychosocial effects of hair loss can be devastating.
Most people know alopecia to be a form of hair loss. However, what they don't always know is that there are three main types of the condition – alopecia areata, alopecia totalis and alopecia universalis.
The first sign of alopecia areata is often a round or oval bald patch on the scalp.
Answer: Alopecia areata and fatigue and cold intolerance
Suppression of adrenal gland function can lead to both fatigue and cold intolerance for example.
Alopecia areata occurs when the body's immune system mistakes hair follicles as foreign and attacks them. This causes the hairs to fall out. This specific form of autoimmunity is a lifelong tendency that can be inherited from either parent.
Alopecia areata is an inflammatory, non-scarring hair loss associated with autoimmune conditions. It is more commonly seen with thyroid disorders and vitiligo, but alopecia areata has also been linked to diabetes, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus.
Alopecia occurs for many different reasons and presents in various ways. It can occur suddenly or develop gradually over time. Sudden-onset causes include illness, diet, medications, and childbirth. Alopecia that has a gradual onset more likely has a genetic component.
Baldness, also known as alopecia, is hair loss, or absence of hair. Baldness is usually most noticeable on the scalp, but can happen anywhere on the body where hair grows. Treatment for baldness depends on the type of baldness and its underlying cause. Most forms of baldness have no cure.
Severe stress is one of several potential causes of alopecia areata, a state in which your body's immune system attacks hair follicles, inducing loss of hair. Hormonal imbalances, often linked with depression, are another potential source of thinning hair and hair loss.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
