- Most children develop varying degrees of developmental disability.
What is the average life expectancy of someone with epilepsy?
Between 1970 and 1980, patients diagnosed with symptomatic epilepsy had a substantially greater reduction in life expectancy (–7.4 years in women and –7.2 years in men) than people diagnosed with idiopathic epilepsy (–5.5 years in women and –5.2 years in men) and people diagnosed with cryptogenic epilepsy (–1.8 years …
What are the 2 main types of epilepsy?
Types of Seizures
- Seizures are generally described in two major groups: generalized seizures and focal seizures.
- The difference between types of seizures is in how and where they begin in the brain.
Will epilepsy shorten my life?
Reduction in life expectancy can be up to 2 years for people with a diagnosis of idiopathic/cryptogenic epilepsy, and the reduction can be up to 10 years in people with symptomatic epilepsy. Reductions in life expectancy are highest at the time of diagnosis and diminish with time.
How is Lennox-Gastaut syndrome diagnosed?
A diagnosis of Lennox-Gastaut syndrome is usually made based upon a thorough clinical evaluation, a detailed patient history and a complete physical and neurological evaluation including advanced imaging techniques, such as electroencephalography (EEG) and magnetic resonance imaging (MRI).
