The article "The Human Factor" talks about the use of artificial intelligence (AI) in medicine. It highlights that AI is being used in various fields, including medical decision-making. A study is mentioned in which the responses of an AI chatbot were compared to the responses of real doctors, and it was found that the chatbot's responses were better rated in terms of quality and empathy. Additionally, the results of several observational studies on the relationship between stress and the onset of alopecia areata (AA) are discussed, concluding that there is no solid scientific evidence to demonstrate that recent distress can directly cause the onset of the disease.

The article discusses a study that observed a thicker choroid in alopecia areata (AA) patients; and suggesting a potential relationship between T lymphocyte-mediated inflammation against melanocytes and choroidal changes in the eye.

Alopecia areata or hair loss occurs in one in 1,000 people. If medical reasons for the hair loss are ruled out, opinion and hypothesis point towards autoimmunity and stress as possible causes. Dealing with the gradual or sudden loss of head hair, eyebrows, eyelashes, nasal, ear and body hair poses unique challenges for those it affects. Autoimmune-associated alopecia areata has no age boundaries and affects children, men and women equally. The dramatic change in appearance can result in psychological trauma, loss in confidence, bullying, low self-esteem and relationship difficulties. [ABSTRACT FROM AUTHOR]
