Description of Medical ServiceDeep brain stimulation delivers electrical impulses to a key central location deep in the brain, suppressing the bursts of epileptic discharges that characterise seizures. Under general anaesthetic, a neurosurgeon places electrode leads into the thalamus of the brain through small holes in the skull. The leads are connected to wires running under the skin behind the ear and down the side of the neck, and are attached to a battery powered neurostimulator device implanted in the upper chest. After implantation, the frequency and amplitude of the delivered electrical stimuli are adjusted to maximally suppress the frequency and severity of seizures.
Description of Medical ConditionEpileptic seizures are characterised by abnormal brain activity, causing sudden and unpredictable changes in behaviour and awareness. The brain area affected, and duration of the seizure determine the seizure manifestations. There are many different underlying causes, including congenital brain abnormalities, acquired lesions and genetic changes.
