MSFinals-5593
A 45-year-old woman is brought in by her daughter because ‘she is acting wild again’. She drinks moderately about once a week. She is not sleeping much, talks incessantly about plans to travel the world and has made many impulsive and irrational purchases. She reports hearing voices but refuses to discuss this issue when questioned by the admitting psychiatrist. She begins a task but does not complete it, all the while making lists of things to be done. She has been starting tasks and not finishing them. She had a similar episode 3 years ago. She also has depressive episodes several times over the last few years and recovered in between them.
What is the most likely underlying diagnosis?
