The freeze-arrest model of catatonia: a critical neuroimaging review with evo-neurobiological integration.
Catatonia is a heterogeneous and poorly defined entity. Akinetic catatonia shares core phenomenology with the adaptive freeze-to-tonic immobility response, a threat-defense system conserved across evolution. It has been suggested that catatonia may be the maladaptive counterpart of the freeze-to-tonic immobility respon...
