It's only been 3 weeks since I underwent deep brain stimulation. When I decided on this complex but established procedure at the Klinikum Rechts der Isar in autumn 2023, I had a clear idea of ​​what would happen in my head whether it works, hope was the father of the thought.

In recent years, THS technology has evolved. Modern procedures now use more advanced imaging techniques and more detailed brain maps to make electrode placement more precise and safer. The electrodes themselves have also evolved. The latest models allow even more precise control of electrical impulses, improving the effectiveness of treatment and reducing side effects.

The operation itself went smoothly. I had imagined it to be worse, especially the waking phases in which I had to react to the electrode alignment, which I experienced as if from a distance. The only thing that remains in my memory is the sound of the drill as it cut its short path through the top of my skull. I didn't realize that the almost 9 hours in the operating room were that long. During this time, the neurosurgeons, aided by state-of-the-art technology, worked precisely through my brain to place the electrodes in the right places. These electrodes would later send out regular pulses of electricity to relieve the symptoms of my Parkinson's disease.

But first a little shock. The treating neurologist, Professor Haslinger, told me the day after the operation that one of the electrodes was not optimally placed, but was about 2-3 mm too deep.

He advised me to have another procedure, which turned out to be completely harmless. The two electrodes now fit perfectly and I am happy and relieved that I didn't make any lazy compromises.

I was surprised at how much my symptoms improved without the device even being turned on. This so-called setting effect lasts about 3 weeks. However, the post-operative adjustment will be a longer process, fine-tuning the stimulator settings and adjusting my medications accordingly.

I have decided against rehab and will instead have the adjustments made on an outpatient basis. In the spring I will go to Bad Gögging for complex therapy, which seemed like the more sensible option to me.

Going forward, I expect a significant improvement in my symptoms and my Quality of life. Although Parkinson's disease will continue to be a part of my life, I hope to have a piece of my old life back.

I will report in six months whether this expectation will be fulfilled.
