Stupor

Template:Search infobox Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

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]

Differential Diagnosis of Underlying Causes

By organ system:

Cardiovascular Arrhythmias such as heart block, Cardiogenic shock, Congestive heart failure, hypertensive crisis, hypotension
Chemical / poisoning Alcohol abuse, heavy metals, hydrocarbons
Dermatologic No underlying causes
Drug Side Effect Anxiolytics, antidepressants, antipsychotics, anticonvulsants, LSD, narcotics, opiates, sedatives
Ear Nose Throat No underlying causes
Endocrine Hyperglycemia, hyperthyroidism, hypoglycemia, hypothyroidism
Environmental Heavy metals, hypothermia,
Gastroenterologic Liver failure
Genetic No underlying causes
Hematologic No underlying causes
Iatrogenic Overdose of anxiolytics, antidepressants, antipsychotics, anticonvulsants, narcotics, opiates, sedatives
Infectious Disease Infection involving the brain {brain abscess, meningitis), an infection complicated by sepsis
Musculoskeletal / Ortho No underlying causes
Neurologic Alzheimer's disease, dementia, 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, seizure, stroke
Nutritional / Metabolic Vitamin D deficiency
Obstetric/Gynecologic No underlying causes
Oncologic Brain tumor
Opthalmologic No underlying causes
Overdose / Toxicity Alcohol abuse, narcotics, opiates, sedatives
Psychiatric conversion disorder, depression, extreme fatigue, schizophrenia
Pulmonary COPD, hypercarbia, hypoxia due to a wide variety of lung diseases,
Renal / Electrolyte Hypercalcemia, hyponatremia, renal insufficiency (acute and chronic)
Rheum / Immune / Allergy No underlying causes
Sexual No underlying causes
Trauma Heat stroke, hypothermia, near drowning
Urologic No underlying causes
Miscellaneous No underlying causes

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.
