A 2015 study
published in JAMA Dermatology has found that people with Alopecia Areata
are more likely to also suffer from Atopic Dermatitis.
The study, conducted by Girish C. Mohan, M.D., and Jonathan I. Silverberg, M.D., Ph.D., M.P.H., of Northwestern University Feinberg School of Medicine in Chicago, conducted a systematic review of data from 33 previous observational studies of patients with Alopecia Areata and Atopic Dermatitis.

Alopecia Areata is a hair loss condition
which causes sudden, patchy hair loss. It has two more severe forms: Alopecia Totalis and Alopecia Universalis
, where all hair is lost on the head and body respectively.
affects approximately one person in every thousand, it is not known what causes the onset of the condition. External factors such as stress are thought to play a part, as are genetics.
Alopecia can come on suddenly, and can be temporary or long lasting. During periods of hair loss
, the hair follicles are dormant, rather than damaged, so hair growth
can re-occur at any time.
Although there is no cure, treatment for Alopecia Areata
can be successful although, as yet, treatment for Alopecia Totalis and Alopecia Universalis
has a less promising track record.
What is Atopic Dermatitis?
Atopic Dermatitis (AD) is an inflammatory skin disorder more commonly known as Atopic Eczema. It is a chronic condition which causes skin to become red, itchy, dry and inflamed. It most commonly appears in skin creases such as behind the knees or inside the elbows, and in the most severe cases, skin can crack and bleed.
One in five children in the UK suffer from Atopic Dermatitis however in over half of cases the condition clears up by the time the child reaches 16. In severe cases, the condition can remain throughout life.
Like Alopecia, the cause of AD is unknown, although genetic factors are thought to play a part. There is also no known cure, although various treatments have been found to reduce the severity of the condition.
Increased risk of Atopic Dermatitis for people with Alopecia
Although it was reported that 9-26% of Alopecia sufferers also had Atopic Dermatitis (compared with 5-20% in the general population) previous studies have been small and found conflicting results as to whether Atopic Dermatitis is increased in patients with Alopecia Areata.
However this systematic review concluded that patients with Alopecia, especially Alopecia Totalis or Universalis, do have a significantly increased risk for Atopic Dermatitis, opening up the possibility of further research to explore potential causes and treatments for both conditions.
