Epileptic seizures can precede the development of a subsequent brain Tumourby many years, suggests research online in the journal OfNeurology Neurosurgery and Psychiatry published.

The risk seems greatest among the aged between 15 and 44 will show the results as Firstadmitted to the hospital for a seizure.

The researchers based their results on first time traffic for Epilepsyfrom the Oxford record linkage study (ORLS) from 1963 to 1998 and national hospital episode statistics (HES) data for England for 1999 to 2005.

These data were then with subsequent diagnosis or deaths of Braintumours link.

The results showed that compared to people for other common Andrelatively minor diseases, those admitted with an epileptic seizure: the first approved almost 20 times as probably a brain of Tumouracross develop both data sets were attendance.

Accounting for the fact that tumors may have missed or not Recordedin the first year after admission for epilepsy, was this number on Betweena 7.5 (HES data) and almost a 9-fold (data ORLS) higher risk.

The risk of developing a cancerous tumor was twice as high as it is a Wasfor not cancer growth.

Acancerous were with epilepsy over 25 times as likely to develop brain cancer and more than 10 times as likely to develop anon cancer growth as those approved for other causes.

The risk was in young people aged between 15 and 44, the times Werebetween 24 (ORLS data) the biggest and 38 times (HES data) rather Mitteangesiedelte brain tumor as people in the same age without epilepsy.

In addition keep the risk for several years after the initial admissions to the hospital, with a more than a six-time greater until 14 years later in the Group of ORLS data and a five-fold risk higher risk up to Sevenyears later in the group data HES.

The authors point out that brain tumours, are Withepilepsy even among these. The overall risk of a brain tumour in 15 to 44-year-old Wasabout 1 to 2%.

"Our study suggests that tumor such as a root cause for epilepsy can obviously Notbecome for several years after the start, and indicates a need for Forongoing vigilance" they write.

The seizure activity can either point a pre-clinical phase of Tumourdevelopment or caused directly by a tumour which show not on MRI scans could, say it.
