SOLUTIONS COMPLETE LEARNING

◉ Seizure - Patho
Answer: *Epileptogenic focus - an abnormally excitable area of the
brain
-More excitatory glutamate transmission
-Disruption in the inhibitory system (GABA)
*Spread of local discharge
-Extracellular K+ stimulates release of glutamate
-Reduction in inhibitory stimuli like densensitization of GABA
receptors with high-frequency stimulation, loss of inhibitory circuits
◉ Guillain-Barre
Answer: A syndrome of rapidly progressive acute demyelination that
affects motor axons leading to ascending muscle weakness
, ◉ Guillain-Barre - etiology
Answer: Epstein-Barr
Cytomegalovirus
HIV
◉ Guillan-Barre - patho
Answer: *Infection breaks down self-tolerance --> autoimmune
reaction that targets peripheral nerve myelin --> loss of nerve
conduction and motor function
◉ Shingles
Answer: Reactivation of latent chickenpox in spinal cord secondary
to decreased immunity
◉ Shingles - patho
Answer: Inflammatory response to virus --> neuronal injury and
loss.
◉ Shingles - clinical manifestations
Answer: *Vesicular skin eruption in the distribution of sensory
dermatome.
*Radicular pain, burning, and tingling
