Dravet syndrome (DS) is a severe form of epilepsy characterized by frequent, prolonged seizures often triggered by high body temperature (hyperthermia), developmental delay, speech impairment, ataxia, hypotonia, sleep disturbances, and other health problems. Dravet syndrome variants lead to a decrease in the level of a crucial protein that normal brain cells use to control the flow of sodium ions into cells. Neurons use these sodium channels to 2021-02-01 · Children with Dravet syndrome initially show focal (confined to one area) or generalized (throughout the brain) convulsive seizures that start before 15 months of age (often before age one). These initial seizures are often prolonged and involve half of the body, with subsequent seizures that may switch to the other side of the body.

These first seizures often occur with a fever (called febrile seizures).

Severe myoclonic epilepsy in infancy (SMEI) is a rare disease, characterized by febrile and afebrile, generalized and unilateral, clonic or tonic-clonic seizures that occur in the first year of life in an otherwise apparently normal infant. They are later associated with myoclonus, atypical absences, and partial seizures. The first onset of seizure is associated with fever. The seizure is tonic clonic in nature, which is characterized by jerking movement on one side of the body. On the first five years of life, the patient experiences myoclonic seizure, which is shock-like jerking movement of the muscles. (1, 2) The first onset of seizure is associated with fever.
