How the schizophrenia concept deteriorated and became a roadblock to the acquisition of knowledge is noted and implications of a clinical syndrome status and Liddle’s proposal in this context are commented on.
Kraepelin’s inspired assertion that dementia praecox is a specific disease entity has seemingly failed the test of time. Is Peter Liddle rescuing the schizophrenia concept? In this commentary, I will first note how the concept deteriorated and became a roadblock to the acquisition of knowledge. Secondly, I will comment on implications of a clinical syndrome status and Liddle’s proposal in this context. Describing the course of the schizophrenia concept over time must be brief in a commentary and assertions are for clarity and open to challenge.
