One of the most common neurological conditions, essential tremor is a progressive shaking of the limbs and can rob a person’s daily independence, according to neurosurgeon Dr Ben Jonker at St Vincent’s Hospital in Sydney.
In January, the team at St Vincent’s used new MRI-Guided focussed ultrasound technology to treat essential tremor in patient, David Harvey.
