From the Research
Features of Formal Thought Disorder
- Formal thought disorder is a complex and multidimensional construct that reflects difficulties or idiosyncrasies in thinking, language, and communication 1
- It is characterized by a range of symptoms, including disorganized and incoherent speech, loosening of associations, and impairment in semantic processing 2
- The neurocognitive basis of formal thought disorder is unclear, but it is thought to involve an impairment in semantic processing and a loosening of meaningful associations 2
Substitution as a Feature of Formal Thought Disorder
- There is no direct evidence to suggest that substitution is a feature of Schneider's formal thought disorder 3, 2, 4, 5, 1
- However, Carl Schneider described several formal thought disorders, including derailment, fusion, omission, suspension, and driveling, but substitution is not explicitly mentioned 5
Related Concepts and Symptoms
- Formal thought disorder is associated with a range of symptoms, including bizarre responses, literal responses, and self-disorder 3
- The relationship between formal thought disorder and self-disorder is complex, and further research is needed to fully understand the underlying mechanisms 3
- The study of formal thought disorder should incorporate the complexity of human communication, including the pragmatic, paralinguistic, non-verbal, and cognitive dimensions of the localized and unique situation where it takes place 4
