Loss of cells

PARKINSON'S occurs as result of a loss of nerve cells in the part of the brain known as the substantia nigra. These cells are responsible for producing a chemical known as dopamine, which allows messages to be sent to the parts of the brain that co-ordinate movement. With the depletion of dopamine-producing cells, these parts of the brain are unable to function normally.

Deep brain stimulation involves the implantation of a wire with four electrodes at its tip into one of three target sites in the brain.

The wire is connected to a small unit called an implantable pulse generator implanted under the skin. When switched on, the IPG produces electrical signals which are sent to the brain to stop or reduce Parkinson's symptoms.
