Episode notes
Define Psychosis By Syndrome, Not Phrase
- Psychosis should be defined precisely, not merely as 'loss of contact with reality'.
- Dr. Fu prefers syndrome-based language tied to underlying processes rather than broad phenomenology.
Use The TALD To Spot Thought Disorder
- Read the TALD (Thought and Language Disorder) scale to recognize varied forms of thought disorganization.
- The TALD lists objective and subjective signs with clear examples that improve detection in clinical practice.
Delusions Defined By Origin And Rigidity
- Delusions are best understood by contrast with culturally or socially derived beliefs.
- Dr. Fu argues delusions are beliefs arising from a psychotic process and remain impervious to reasoning.
