Abstract: The concept of Formal Thought Disorder (FTD) is an ambiguous and disputed one,
even though it has endured as a core psychopathological construct in clinical Psychiatry. FTD can
be summarized as a multidimensional construct, reflecting difficulties or idiosyncrasies in thinking,
language, and communication in general and is usually subdivided into positive versus negative.
In this article, we aim to explore the putative neurobiology of FTD, ranging from changes in
neurotransmitter systems to alterations in the functional anatomy of the brain. We also discuss recent
critiques of the operationalist view of FTD and how they might fit in its biological underpinnings.
We conclude that FTD might be the observable phenotype of many distinct underlying alterations
in different proportions.
