I had DBS, Bi Lateral, installed back in July this year. I went in teatime on the Wednesday and was home by Friday teatime. The general anaesthetic side effects lingered for a few days, I was constantly loosing my thread in conversations, don't let that panic you, all good now. The build up process to the op can be quite draining not only for the patient but also their nearest and dearest, consequently the sense of relief is huge following the op. Roughly week two onwards the brains reaction to the operation is often positive, this honeymoon period left me pretty much symptom free. It wanes gradually, bearing in mind I didn't get switched until 6 weeks post op.
In terms of risks my Parkinson's Nurse assured me that no one gets as far as the op if even the slightest thing pushes the risk beyond the norm for that individual.
I was switched on in August and have since been able to cut my pill intake down to only 25% of the pre op level. I started back to work full time in post op week 7.
If you'd like to hear my Wife's experience of my DBS feel free to send a PM through this forum.
Which hospital will be doing the op? Do you know which make of unit they will install? Mine is Boston Scientific with "steerable" current electrodes.
Best wishes for the outcome we all aim for.
