Overview
Stupor is the lack of critical cognitive function and level of consciousness wherein a sufferer is almost entirely unresponsive and only responds to base stimuli such as pain. akinesis and mutism are present but with relative preservation of conscious awareness. A person is also rigid and mute and only appears to be conscious as the eyes are open and follow surrounding objects (Gelder, Mayou and Geddes 2005).
Historical Perspective
The word derives from the Latin stupure, meaning insensible.[1]

Differentiating stupor from other conditions
Stupor is not the same thing as a coma or a vegetative state. For example, some people who become injured suddenly with a concussion or some other cognitive impairment resulting from injury enter a stupor, where they are partially aware of their surroundings, or they become unconscious until they are revived by themselves or by others. This is often[citation needed] mistaken for delirium and treated with Haldol and or other anti-psychotic drugs.
Diagnosis
Symptoms
If not stimulated externally, a patient with stupor will be in a sleepy mode most of the time. In some extreme cases of severe depressive disorders the patient can become motionless, lose their appetite and become mute. Short periods of restricted responsivity can be achieved by intense stimulation (e.g. pain, bright light, loud noise).
CT Findings
Lesions of the Ascending Reticular Activation System on height of the pons and metencephalon have been shown to cause stupor. The incidence is higher after left-sided lesions.
