- Stupor
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. The word derives from theLatin "stupure", meaning insensible. Being characterised by impairments of reactions toexternal stimuli, it usually appears ininfectious disease s, complicatedtoxic states, severehypothermia ,mental illness es (e.g.schizophrenia ),vascular illnesses (e.g.hypertensive encephalopathy ),neoplasms (e.g.brain tumor s), vitamin D deficiency and so on.ymptoms
If not stimulated externally, a patient with Stupor will be in a sleepy mode most of the time. Short periods of restricted
responsivity can be achieved by intensestimulation (e.g. pain, bright light, loud noise).Localisation of brain lesions
Lesions of the Ascending Reticular Activation System on height of the
Pons andMetencephalon have been shown to cause Stupor. The incidence is higher after left-sidedlesion s.ee also
