The first symptoms of Parkinsonâ??s disease can be hard to diagnose, especially in older patients, and often start out mild and worsen over time. The most common signs of Parkinsonâ??s disease are shaking, called tremors, and jerky, stiff movements. Some of the other possible signs include:
Depression, anxiety, and memory loss
Slowed movements, slow blinking, and slowed speech
Difficulty swallowing and drooling
Problems with balance and walking
Deep brain stimulation is a technique that has been used for years now to treat conditions like Parkinsonâ??s, dystonia, and essential tremor. The procedure to put the electrode in place usually takes place with the patient awake, because brain mapping is easier when the patient isnâ??t under anesthesia and so doctors can periodically check with the patient. However, now doctors can use MRI to place the electrodes needed for the neurostimulator. This means the patients can be put under general anesthesia for the surgery. The MRI helps doctors visualize in real time where the electrode needs to be placed. This is important for patients who are nervous, canâ??t tolerate being awake, or too dystonic to be still during a surgery.
