I know an individual with Bipolar Type II who gained their PhD, and had two extended hospitalisation for mania during the time. They were given substantial extensions by supervisor, and supported by her university throughout.
I think the honest answer would be, with the right supervision and the right university, there would be no barrier, and adaptations would be made for learning. There chances of getting that combo is possibly as high (or low!) as it is for anyone else, as academia is an incredibly competitive and luck driven field.
Mental illness like previously discussed is broad. Identifying the individuals specification will help better understanding. Majorly what's needed is support from all quarters and an emotional stability.
In addition to the valuable input from other responses, universities are increasingly implementing measures informed by disability and diversity to enhance the inclusivity of higher education programs, which is something promising to look forward to. Continuous quality care and support would make the right difference for anybody.
In the United States, students with serious mental illnesses are protected under Special Education
laws. If a student is identified and receives an Individualized Educational Plan (IEP
), they may receive services.
Many institutions offer PhDs in mental health programs, including online classes. One can search for a program and contact the school's admission office directly.
If anyone has a mental or physical diagnosis Michigan rehabilitation services (a .gov site) will pay for vocational or other schooling. they will even provide Job coaching etc
What lies beneath this question is a well known stereotype; menthal illness equal low IQ. In my opinion, the best way to contribute to this discussion is to help people address this cognitive distorsion.
