3. Epilepsy
Epilepsy is a condition that causes a person to experience sudden seizures on a regular, chronic basis. It is a mistake to believe that all seizures are caused by epilepsy (though it is a pervasive belief). In truth, over a third of all seizures have unknown causes.
Epilepsy itself can have a great number of different causes. Often it is genetic and therefore will be present from birth. In other cases, it can be the result of a traumatic or unusual birth. It’s also possible though for epilepsy to develop later in life – as a result of subsequent trauma, or even without an obvious explanation.
As with many conditions, it is likely that a person can be born with a genetic susceptibility to epilepsy, but that this will then be more likely to come to fruition only under the right circumstances.
