Che cosa causa l'epilessia e le convulsioni riducono la vita di una persona?
Autore:Epilepsy is a neurological disease, characterised by attacks or seizures that recur in episodes over time. An underlying brain abnormality causes the seizures and they can be tonic-clonic in nature or much less subtle. Here to tell us about the underlying causes of epilepsy and how seizures can affect life expectancy is Doctor Dora Lozsadi.
Anyone can develop epilepsy at any stage of their life. However, it is far more common in children and over the age of 65. The underlying abnormality that causes epilepsy can vary. Epilepsy in children is mostly genetic, where a finite molecular abnormality in the brain affects how nerve cells communicate with each other. This abnormality is what causes seizures. Developmental abnormalities are also a cause, where abnormalities in blood vessels or developmental problems before birth can lead to epilepsy. Childhood trauma can also be to blame.
Later in life, structural abnormalities in the brain are more likely to cause epilepsy, but the underlying genetic predisposition for epilepsy will determine whether a person gets epilepsy or not. Older people who suffer from strokes or people who develop tumours are at a greater risk of developing epilepsy.
Are all seizures related to epilepsy?
No, not all seizures are related to epilepsy. Under certain conditions, the brain can generate a seizure, for example, if a person is lacking in oxygen, dehydrated or have had a large amount of alcohol. The seizure may unmask a genetic propensity for epilepsy but doesn’t mean that the person will go on to have the condition. Epilepsy in contrast to provoked, isolated seizures, generally involves two or more unprovoked seizures that occur over a period more of more than 24 hours.
Does epilepsy reduce life expectancy?
As a consequence of the underlying brain abnormality in people with epilepsy, reduced life expectancy is expected. Patients with poorly controlled epilepsy will have a lifespan reduced by approximately 10 years. Those who control it well may only have their life expectancy reduced by 2 years.
A child with learning difficulties and epilepsy, for example, can have a reduced life expectancy by decades, but someone without structural abnormalities in the brain, with normal memory and cognition, will have little or no reduction to their life expectancy.
Good control of epileptic seizures and knowing how to deal with them when they occur is the key to living longer with epilepsy. If you have epilepsy and would like to talk about your case, reach out to a specialist who can offer you their guidance and support.
