Is it a bad idea to discuss my brother's mental illness in my personal statement?

Hello,

About 3 years ago my brother was diagnosed with a disorder similar to schizophrenia (schizoaffective disorder). When he first started showing symptoms he could not recieve proper care because there was no psychiatrist that would take him as a patient (all of them were full). His experience really inspired me to become a psychiatrist, seeing his hardships and struggles. I was wanting to discuss how his experience has shaped me considering the care my family and I had to give to my brother. I was wondering, however, if this was a bad idea due to the stigma associated with mental health. Thanks.
