The Glasgow Coma Scale looks at?
Motor, verbal, and eye opening responses
What is the normal intracranial range?
5 - 10 mmHg
A temporary interruption of blood supply to the brain.
Transient ischemic attack (TIA)
Persistent high blood pressure can be a cause.
Stroke
- Pain and temperature loss on the opposite side of the lesion.
- Proprioception loss on the same side of the lesion.
Brown-Sequard syndrome
- motor functions remain intact
- pain and light touch remain intact
- loss of proprioception
Posterior cord syndrome
Mechanism of injury is primarily hyperextension.
Central cord syndrome
The mechanism of imjur is usually a direct penetration by a foreign object damaging one side of the spinal cord.
Brown-Sequard syndrome

GCS
A nonmalignant overgrowth of bone is?
Heterotopic ossification (HO)
Cauda equina injury will present with?
Bowel and bladder incontinence
- difficulty with spatial perceptual tasks
- impulsive behavior
Right-hemisphere stroke (Left-hemi)
- expressive and/or receptive aphasia
- slow and cautious
Left-hemispheric stroke (Right-hemi)
What are the kinds of stroke?
Clot and bleed
A portion of the brain receives no blood while a surrounding area receives sufficient blood from collateral circulation to stay alive but not to sustain function.
Ischemic penumbra
Bleeding from an arterial source into brain parenchyma.
Intracerebral hemorrhage
Hyperactive flexor reflexes in the UEs and hyperactive extensor response in the LEs.
Decorticate posturing
Hyperactive extensor reflexes in both the upper and lower extremities.
Decerebrate posturing
The primary cause of SCI is?
MVA
Loss of sensory, motor, and autonomic control below the lesion right after the injury is?
Spinal shock
Occurs with a lesion above T5 and is the result of impaired function of the ANS caused by simultaneous sympathetic and parasympathetic activity.
Autonomic dysreflexia
- sudden onset of throbbing or pounding headache
- sweating and flushing of the face, neck, & shoulders
- sudden and significant increase in BP
