47 Possible Causes for Decorticate Posture, Fixed Pupils

  • Brain Stem Herniation

    Decorticate posturing (figure top) is recognized as bilateral flexion at the elbows and wrists, shoulder adduction and extension of the lower extremities occurring with lesions[casemed.case.edu] The result is usually fatal. [9] Other symptoms of this type of herniation include small, fixed pupils with [10] paralysis of upward eye movement giving the characteristic[en.wikipedia.org] Hyperventilation or Cheyne-Stokes Absent (eyes fixed) Decerebrate posturing, or nothing Lower pons and medilla Both pupils fixed and unreactive Apnoea Absent (eyes fixed)[derangedphysiology.com]

  • Brain Death

    Criteria for establishing brain death (BD) require absence of all brainstem-mediated reflexes including motor (ie, decerebrate or decorticate) posturing.[ncbi.nlm.nih.gov] A 28-year-old man was admitted following a road traffic accident with a Glasgow Coma Score (GCS) of 3/15 and fixed pupils.[ncbi.nlm.nih.gov] Components of a complete neurological examination are: Examination of the patient-absence of spontaneous movement, decerebrate or decorticate posturing, seizures, shivering[ncbi.nlm.nih.gov]

  • Bacterial Meningitis

    posturing Bilaterally dilated and fixed pupils Loss of vestibulo-ocular reflexes (tested by calorie stimulation or Doll's eye maneuver) Loss of deep tendon reflexes Isoelectric[atsu.edu] The pupils may be unequal and react sluggishly; they may even become dilated and fixed as the disease progresses. Squint and diplopia with ptosis are common.[atsu.edu] […] false-localizing sign in 20% of cases) Cortical blindness (rare) Coma Irregular respiration (Cheyne- Stokes, central neurogenic hyperventilation) Unilateral or bilateral decorticate[atsu.edu]

  • Coma

    A decorticate posturing indicates a lesion (a point of damage) at or above the red nucleus , whereas a decerebrate posturing indicates a lesion at or below the red nucleus[en.wikipedia.org] A 70-year-old man with coma (Glasgow Coma Scale score of 6) with fixed dilated pupils because of severe intracranial hypotension is described.[ncbi.nlm.nih.gov] […] dilated pupil, and brainstem signs, who had emergency DC, is presented.[ncbi.nlm.nih.gov]

  • Metabolic Encephalopathy

    posturing. • Respiratory patterns, along with blood gas (acid-base balance) testing can narrow the differential diagnosis considerably.[medlink.com] […] results in mid- to large-sized sluggish or fixed pupils [ 2 ].[aneskey.com] Decorticate and decerebrate reflex posturings with noxious stimulation are commonly seen with progressive metabolic suppression of any type.[dartmouth.edu]

  • Dysautonomia

    posturing.[ncbi.nlm.nih.gov] pupils, excessive sweating, loss of pain and temperature sensation, and absent reflexes; pathologic features include reduced numbers of small diameter peripheral nerve fibers[de.dict.md] Features of the syndrome include severe, paroxysmal increases in heart rate, respiratory rate, temperature, and blood pressure, with decerebrate or decorticate posturing,[jnnp.bmj.com]

  • Hematoma

    Decorticate and decerebrate posturing or lack of any motor function should also be recorded. Assess the size and reactivity of both pupils.[emedicine.medscape.com] Some of the above may occur later in the clinical course; for instance, coma with a dilated fixed pupil usually indicates unilateral transtentorial herniation.[emedicine.medscape.com]

  • Reye Syndrome

    […] and decerebrate posturing Seizures Flaccidity Fixed dilated pupils Respiratory arrest Focal neurologic findings usually are not present.[merckmanuals.com] , large pupils, and loss of corneal reflexes Brainstem dysfunction Minimal liver dysfunction Manifestations of Stage 5 Hypotonia Seizures Respiratory arrest Absence of liver[quizlet.com] There is decorticate (flexor) posturing with intact pupillary light reflexes. . . . . .[hawaii.edu]

  • Encephalopathy

    posturing. • Respiratory patterns, along with blood gas (acid-base balance) testing can narrow the differential diagnosis considerably.[medlink.com] Involvement of the midbrain (midposition and fixed pupils) would have occurred as part of the rostrocaudal process with the exception of the rare intraventricular hemorrhage[dartmouth.edu] […] and decerebrate posturing, muscle spasticity, and bilateral extensor plantar reflexes.[fpnotebook.com]

  • Basilar Skull Fracture
