This is a type of seizure that starts in a focal area of the brain and spreads to the rest of the brain.
In many cases, the trigger for this abnormal electrical activity in the brain is unknown, but it has been associated with trauma, infection and toxic substances.
Its initial symptoms are localised in a specific part of the body, such as repetitive arm movements, which later develop into generalised loss of consciousness and seizures.
The diagnosis is made clinically, by interview and physical examination. To confirm the diagnosis, an electroencephalogram must be carried out and additional tests may be carried out to investigate the cause of the onset.
Childhood epilepsy sometimes resolves spontaneously with the onset of puberty. In the meantime, anticonvulsants are used to control the seizures.
