Catatonia was initially a clinical presentation of certain types of schizophrenia, but basic and epidemiological evidence has demon-strated its association with multiple somatic and psychiatric conditions. We describe and discuss current clinical, etiological, patho-physiological, and therapeutic concepts regarding catatonia. We conducted a broad narrative review of articles published in MEDLINE/PubMed. The diagnosis is clinical and can be supported by additional tests, but there are psychometric instruments with different clinical focus. The most validated subtypes are inhibited and excited catatonia. It is mostly associated with somatic, neurological, affective, psychotic, and autistic spectrum disorders. Genetic factors related to oligodendrocytes have been studied in its pathophysiology. Some findings point to an imbalance in neurotransmission and density of GABA and dopamine receptors, consistent with their function in motor pathways and therapeutic response with benzodiazepines. Likewise, glutamatergic activity has been analyzed from the pathophysiological model of autoimmune encephalitis. The cortico-cortical and cortico-subcortical pathways would have a central role, including structures such as the orbitofrontal and temporal cortex, basal nuclei, and brainstem, involved in decision-making, emotion regulation, storage, planning, and motor processing. The main therapeutic lines are benzodi-azepines and electroconvulsive therapy. Other interventions studied are zolpidem, antipsychotics, mood stabilizers, glutamatergic modulators, and transcranial magnetic stimulation. New neurobiological findings challenge nosological and therapeutic precepts, renewing the cycle in the conceptualization of catatonia. We highlight the affective component of the psychomotor syndrome and the role of interventions aimed at its modulation.
