The FDA has approved devices for use in the United States in the treatment of epileptic seizures[1] and chronic pain[2] conditions.
Devices are being studied for use in the treatment of essential tremor,[3] Parkinson's disease,[4] Tourette's syndrome,[5] depression,[6] obesity,[7] and post-traumatic stress disorder.
[9] The device keeps a record of abnormal electrical activity that is reviewed by a neurologist to improve the detection and treatment of seizures.
Continuous, or non-responsive, neurostimulation has been FDA approved since 2002 with the introduction of deep brain stimulators for Parkinson's disease.
[14] At this time, there are clinical trials for reponsive neurostimulation devices in the treatment of essential tremor,[3] Parkinson's disease,[4] Tourette's syndrome,[5] depression,[6] obesity,[7] and post-traumatic stress disorder.
