How does hypotonia relate to dandy walker syndrome?

Cerebellar disorder: The dandy walker malformation is a defect of the outflow of fluid from the fourth ventricle of the brain. This can result in a large cyst, and can be associated with poor development of the cerebellum. Poor cerebellum function can result in poor muscle tone and poor balance that can be called hypotonia. This usually responds to therapy. Usually no surgery is necessary unless the cyst is severe. ...Read more

Have read that people with chiari 1 malformations can have cerebellar fits. What is the difference betw. A cerebellar fit & a tonic clonic seizure?

Some differences: Cerebellar fits"characterized by drop attacks with/without deterioration of consciousness, opisthotonic posturing(head and back arching backward), and varying degrees of respiratory compromise. Cerebellar fits may mimic other disorders such as cardiogenic syncope and epileptic seizures. Tonic/clonic (grand mal seizure) generalized seizure with muscle contractions and loss of consciousness. ...Read more
