1. A method comprising:
delivering, via an electrode implanted in a brain of a patient and stimulation circuitry, electrical stimulation therapy comprising an electrical stimulus;
monitoring an electrical current generated by the stimulation circuitry to deliver the electrical stimulus;
determining, based on the electrical current, a value representative of a concentration of dopamine in the brain of the patient;
determining, based on the value representative of the concentration of dopamine, a value for one or more stimulation parameters that at least partially define subsequent electrical stimuli of the electrical stimulation therapy; and
delivering, via the electrode, the subsequent electrical stimuli of the electrical stimulation therapy according to the value of the one or more stimulation parameters.
