Epilepsy and light

It is looking like transcranial photobiomodulation could improve epilepsy that results from having a stroke.

Having a stroke is a scary thing. So many parts of the body can be affected and the likelihood of full recovery is incredibly variable. To add to the misery, you can be left with epilepsy.

If you are even more unlucky, you will be one of the one third of people whose epilepsy doesn’t respond to standard medications. Treatment-resistant epilepsy is a dreadful burden to the individual and the family.

Dr Vogel’s research team looked at the effect of light on the heads of rats who had stroke-induced epilepsy. They compared recordings of brain activity from before starting transcranial light and sixty days after treatment.

They found that the rats who had been treated with transcranial light had fewer seizures and the duration of seizures had shortened.

While this is a very early report, it strongly suggests that transcranial photobiomodulation could reduce the impact of epilepsy in people who have had a stroke. This is exciting work.
