26 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] At this point, the left pupil became fixed. An ICP bolt was inserted (opening pressure 50 mm Hg; Figure ).[stroke.ahajournals.org] The disrupted brainstem can lead to decorticate posture , respiratory center depression and death.[en.wikipedia.org]

  • Brain Death

    INTRODUCTION: 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]

  • Reye Syndrome

    […] and decerebrate posturing Seizures Flaccidity Fixed dilated pupils Respiratory arrest Focal neurologic findings usually are not present.[merckmanuals.com] Stage IV: Seizures are present and are accompanied by a deepening coma, decerebrate rigidity, loss of oculocephalic reflexes, and fixed pupils.[web.archive.org] There is decorticate (flexor) posturing with intact pupillary light reflexes. . . . . .[hawaii.edu]

  • 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] […] disturbances in cerebral function, the pupillary reactions are typically spared, even if other cranial nerve reflexes are lost and the patient is exhibiting decerebrate or decorticate[medlink.com]

  • 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] CASE DESCRIPTION: 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]

  • Cerebral Edema

    Diagnostic criteria - abnormal motor or verbal response to pain, decorticate or decerebrate posture, cranial nerve palsy, abnormal neurogenic respiratory pattern (grunting[childrensmercy.org] Overnight, she acutely became unresponsive with fixed dilated pupils, tachycardia, and hypertension.[ncbi.nlm.nih.gov] Muir et al published a Bedside Evaluation of Neuro State of Kids with DKA Diagnostic Criteria Abnormal motor or verbal response to pain Decorticate or Decerebrate posture[emdocs.net]

  • Dysautonomia

  • Intracranial Hemorrhage

    Initial emergency room evaluation found the patient to have anisocoria with a fixed and dilated right pupil and demonstrated evidence of decorticate posturing.[ncbi.nlm.nih.gov] The pupils are now fixed and dilated. Abnormal posturing is absent. A brain CT scan is ordered.[foamcast.org] Initial emergency room evaluation found the patient to have anisocoria with a fixed and dilated right pupil and demonstrated evidence of decorticate posturing.[ncbi.nlm.nih.gov]

  • Primary Amebic Meningoencephalitis

    He also presented with a stiff neck and decorticate posturing. His blood pressure was 104/60 with a pulse rate of 126 bpm and body temperature of 39 C.[bmcinfectdis.biomedcentral.com] On November 18, neurologic findings included fixed nonresponsive pupils, no response in the upper or lower extremities, muted plantar responses, and no response to verbal[ncbi.nlm.nih.gov] […] and follows, although reactive pupils, had unsteady and wide base gait.[pjms.com.pk]
