Over the past three decades, catatonia research has experienced a remarkable renaissance, driven by the application of diverse methodologies and conceptual frameworks. This renewed interest has significantly reshaped our understanding of catatonia, a complex syndrome with multifactorial origins spanning epidemiology, historical context, phenomenology, genetics, immunology, and neurobiology. These advancements have offered a more comprehensive and nuanced perspective, culminating in the recognition of catatonia as a distinct diagnosis in the ICD-11 – a landmark development that underscores its clinical and scientific relevance. Despite these strides, several unresolved issues remain that require future research. Bridging these gaps is crucial not only to enhance our understanding of catatonia but also to identify the most effective treatments and uncover the mechanisms underlying their efficacy. Such advancements hold the promise of developing improved diagnostic markers and tailored therapeutic strategies, offering significant benefits to patients affected by this challenging condition. In this chapter, we explore the profound implications of catatonia research, spanning its impact on clinical psychiatry and neuroscience, as well as its broader contributions to our understanding of the intricate relationship between the brain and mind.
