    Abstract: A stimulation therapy system dynamically modifies therapy intensity based on measured neurotransmitter levels. In some examples, the system delivers, via an electrode implanted in a brain of a patient and stimulation circuitry, an electrical stimulus; monitors an electrical current generated by the stimulation circuitry to deliver the electrical stimulus; determines, based on the electrical current, a value representative of a concentration of dopamine in the brain of the patient; determines, based on the value representative of the concentration of dopamine, a value for one or more stimulation parameters that at least partially define electrical stimulation therapy; and delivers, via the electrode, the electrical stimulation therapy.
