Lambert-Eaton Syndrome - CORRECTANSWER A syndrome caused by autoantibodies that inhibit
the function of presynaptic calcium channels, leading to decreased release of acetylcholine into
the synaptic cleft
Lambert-Eaton - Clinical Manifestations - CORRECTANSWER *Strong link to lung cancer
*Muscle weakness that IMPROVES with repetitive stimulation
*Do not respond to cholinesterase inhibitors
,Spinal cord trauma - patho - CORRECTANSWER *Microscopic hemorrhages in central grey
matter
*Axonal edema in white matter --> ischemia --> injury and degeneration
*Release inflammatory mediators -->necrosis and scar tissue formation
*Injury is maximal at injury site and two cord segments above and below it
Spinal cord trauma - Clinical manifestations - CORRECTANSWER *Spinal shock (normal activity
of the spinal cord stops at and below level of injury. Loss of spinal reflexes.)
*Paraplegia, quadriplegia
*Autonomic dysreflexia
Brown-Sequard Syndrome - CORRECTANSWER Occurs when there is trauma or lesion that
affects one half of the spinal cord. Typically occurs in the cervical region.
Brown-Sequard Syndrome - Clinical Manifestations - CORRECTANSWER *Loss of proprioception
on the SAME side as the lesion
*Loss of voluntary motor function from the corticospinal tract on the SAME side as the lesion
*Loss of pain and temperature on the OPPOSITE side of the lesion
, Syringomyelia - CORRECTANSWER The presence of a cavity in the spinal cord. Usually caused by
a tumor, cyst, or trauma.
Syringomyelia -Clinical Manifestations - CORRECTANSWER Loss of pain and temperature
sensation on both sides at the level of the lesion (Due to the crossing of the lateral
spinothalamic tract)
Stroke - Types - CORRECTANSWER *Ischemic (embolic, thrombolic)
*Hemorrhagic
Atherosclerosis - CORRECTANSWER Most common cause of thrombotic stroke
Internal carotid, middle cerebral, posterior cerebral, and basilar artery - CORRECTANSWER
Common sites of thrombotic stroke
Lacunar stroke - CORRECTANSWER Microinfarcts that involve small cerebral arteries that
penetrate the brainstem and thalamus. May be clinically silent or produce motor and/or
sensory deficits
Embolic stroke - CORRECTANSWER Emboli traveling through the heart, aorta, and carotic
arteries occlude the middle cerebral artery.
Emboli traveling the vertebral and basilar arteries occlude the apex of the basilar artery
Ischemic stroke - pathogenesis - CORRECTANSWER *Nerve cells within the ischemic focus are
damaged and killed by energy deprivation
