Epilepsy
is a common problem affecting 1 in 200 of the population. In
20% of patients with focal epilepsy (in which seizures originate
from a specific region of the brain) tdrug treatment is not effective.
Surgical treatment is increasingly being used in these patients
and can lead to complete or almost complete seizure control in up
to 80% of cases. This demands accurate identification of the
seizure focus. Our research has enabled non-invasive brain
imaging methods to be developed.
This
picture shows two blood flow scans of an epilepsy patient. The
one on the left shows the pattern of blood flow in the brain between
fits and the one on the right during a fit. The change enables
the damaged tissue to be identified and, where appropriate, removed.

The
part of the brain causing the epilepsy can be identified by its
reduced blood flow between fits and very high blood flow during
a
fit.
