Episode notes
Anhedonia Is The Silent Core Symptom
- Anhedonia is a quiet numbing of pleasure and interest that shows up in depression, trauma, substance use and dementia.
- Judith Joseph describes people saying they feel "meh" or "bleh" and using busying or numbing behaviours to avoid the pain.
Depression Can Hide Behind High Performance
- High-functioning depression looks like people who continue to perform but feel empty, and it often gets missed because they don't meet classic diagnostic thresholds.
- Judith Joseph notes that many patients still deliver at work and hide pain until crisis points like suicide occur.
Judith Joseph's Personal Experience With High Functioning Depression
- Judith Joseph shares her own experience of running a lab, caring for family and pushing through pain during the pandemic.
- She says she suffered from high-functioning depression while still managing work and home responsibilities.
