Shapiro syndrome
Encyclopedia
The Shapiro syndrome is a rare disorder consisting of paroxysmal hypothermia
(due to hypothalamic
dysfunction of thermoregulation
), epilepsy
, and agenesis of the corpus callosum
with onset typically on adulthood. The disease affects about 50 people worldwide. The duration and frequency of the episodes vary from person to person, with some episodes lasting hours to weeks and occurring from hours to years. Very little is known about the disease due to the small number of people affected.

Epilepsy is a common chronic neurological disorder characterized by seizures. These seizures are transient signs and/or symptoms of abnormal, excessive or hypersynchronous neuronal activity in the brain.About 50 million people worldwide have epilepsy, and nearly two out of every three new cases...

Agenesis of the corpus callosum
Agenesis of the corpus callosum is a rare birth defect in which there is a complete or partial absence of the corpus callosum. Agenesis of the corpus callosum occurs when the corpus callosum, the band of white matter connecting the two hemispheres in the brain, fails to develop normally,...
