Children who are newly diagnosed with epilepsy are also at risk of developing cognitive problems, a new study has found.
Youngsters who recorded a normal IQ before their first seizure may go on to experience cognitive skills, such as language, memory and learning issues as early as three months after the attack.
Related factors such as the impact of multiple seizures, taking epilepsy drugs, or signs of epilepsy on early tests of brain waves were all investigated as part of the research.
Dr Philip Fastenau, professor of Neurology at Case Western Reserve University School of Medicine and the Neurological Institute of University Hospitals in Cleveland, Ohio, commented on the findings.
He said: "Our study highlights the importance of testing children with epilepsy for possible cognitive problems soon after they are diagnosed with epilepsy in order to avoid these issues affecting them later in life, especially if they have additional risk factors."
Earlier this month, scientists discovered a gene that has a pivotal role in the development of epilepsy, prompting hopes for a cure.
