Patients can sleep and wake, have some sensory reactions, have some voluntary movements, and have some self or environment awareness {stupor} {minimally conscious state}. Stuporous means semi-conscious, semi-aware, and few sensations.
causes
Damage to cortico-striatopallidal-thalamocortical loop disconnects frontal lobes, basal ganglia, and thalamus. Bilateral anterior medial cortex, basal ganglia, and basal forebrain damage causes stupor.
A schizophrenia type involves excitement and then stupor.
types
Bilateral anterior-medial-cortex, basal-ganglia, and basal-forebrain damage, typically from anterior cerebral-artery aneurysm, can cause no motion, except to look around (akinetic mutism). Medial-caudal-thalamus, medial-dorsal-mesencephalon, caudate-nucleus, globus-pallidus, and medial-forebrain-bundle damage can cause no memory, slow behavior {slow syndrome}, and apathy.
Extensive temporal-lobe, parietal-lobe, and occipital-lobe junction damage can prevent self or environment awareness but allow coordinated behavior (hyperkinetic mutism).
