The only invasive EEG testing/recording is the type where the electrodes have to be surgically implanted. Otherwise, EEG is noninvasive.
You mentioned that your last test was 10 years, ago. A lot has changed in the way of EEG testing and treatment, ie, HD-EEG. I had my first experience with EEG treatment, approximately, 5 years, ago, and then 3 years, ago, and I have just had 2 treatments, recently, for residual symptoms from trauma, anxiety and sensory, auditory and visual processing.
