Abstract :
Dear Editor,
Hemodynamic dysregulation due to autonomic
nerves involvement is common in Guillain‑Barre
syndrome (GBS). About 61% of patients suffering
from GBS have transient hypertension and 43% have
postural hypertension.[1] Persistent hypertension is not
a prerequisite for posterior reversible encephalopathy
syndrome (PRES) and 15 to 20% of subjects with PRES are
normotensive or hypotensive.[2] Transient hypertension
is sufficient to disrupt the autoregulation and lead to
PRES. Moreover, the upper limit for autoregulation
varies between different individuals. Our patient did
not have persistent hypertension, but could have had
transient hypertension.
