About Deep Brain Stimulation Device:
- The device uses DBS, which is also utilised for movement disorders associated with Parkinson’s, and other neurological conditions.
- Working
- The neurostimulator delivers constant electrical impulses to the brain to disrupt or block abnormal seizure-causing signals.
- A 3.5 cm square, 0.6 cm in thickness, the device was surgically implanted in Knowlson’s skull and anchored using screws.
- The doctor then inserted two electrodes deep into his brain until they reached the thalamus — a relay station for all the motor and sensory information. The ends of the electrodes were connected to the neurostimulator.
- The device was switched on after Knowlson recovered from his surgery. It can be recharged by a wireless headphone.
What is epilepsy?

- The disease has no identifiable cause in nearly 50% of the cases.
- Reasons for epilepsy: Head trauma, Tumours in the brain, some infections like meningitis, or even genetics can lead to epilepsy. It can increase the risk of accidents, drownings and falling.
