Stupor is characterised by impaired reaction to external stimuli. Those in a stuporous state are rigid, mute and only appear to be conscious, as the eyes are open and follow surrounding objects. If not stimulated externally, a patient with stupor will appear to be in a sleepy state most of the time. In some extreme cases of severe depressive disorders the patient can become motionless, lose their appetite and become mute.^[1] Short periods of restricted responsivity can be achieved by intense stimulation (e.g. pain, bright light, loud noise, shock).^{[citation needed]}
