Anna O.

Anna O. was a patient treated by psychiatrist Josef Breuer in the late 19th century. She experienced neurological symptoms like paralysis, blindness, and hallucinations, which medical tests couldn't explain. Through therapy, she talked about her memories and emotional struggles, which seemed to reduce her symptoms. This case was important because it helped develop the idea that psychological factors could cause physical symptoms, laying groundwork for psychoanalysis. Anna O.'s actual name was Bertha Pappenheim, and her case remains influential in understanding mind-body connections in mental health.
