Catatonia: the Alteration in Stupor and Excitation. The data for this graph was gathered from the nursing notes documented over the course of a 3-week admission prior to the diagnosis of catatonia. Four of the authors independently reviewed the notes and rated the psychomotor behavior from −2 to +2. Excitation was scored as a 2, stuporous catatonia was rated a negative 2. Further information on this scale can be found in the Supplementary Material.
