From the Research
Formal Thought Disorder Symptoms
- The study by 1 mentions that Carl Schneider described several Formal Thought Disorders such as:
- Derailment
- Fusion
- Omission
- Suspension
- Driveling
- However, these symptoms are not specifically referred to as Schneider's first-rank symptoms of formal thought disorder.
Schneider's First-Rank Symptoms
- The study by 2 discusses the prehistory of Schneider's First-Rank Symptoms, which include:
- Somatic passivity
- Thought insertion
- Thought withdrawal
- Made actions
- These symptoms are not directly related to formal thought disorder, but rather to a broader range of psychotic symptoms.
- The study by 3 examines the relationships between Schneider's First-Rank Symptoms and major aspects of psychopathology in schizophrenia, but does not provide a list of specific symptoms related to formal thought disorder.
- The study by 4 reviews the concepts of First Rank Symptoms and their diagnostic utility, but does not provide a clear list of symptoms related to formal thought disorder.
Conclusion on Formal Thought Disorder Symptoms
- Based on the available evidence, it appears that Schneider's first-rank symptoms are not specifically related to formal thought disorder, but rather to a broader range of psychotic symptoms.
- The symptoms described by Carl Schneider in the study by 1 are related to formal thought disorder, but are not referred to as first-rank symptoms.
