Jay1 Posted November 25, 2013 Report Share Posted November 25, 2013 anyone given this a try? http://en.wikipedia.org/wiki/Transcranial_direct-current_stimulation Sounds queit interesting (and safe) treatment for depression, but can also be used to minimise Anxiety and other things conected to hppd. I have been reading up on the areas of the brain that you can target and you could minimise the activity in the visual cortex, which could help us. It is very short lasting, but you can retrain your brain with very short 10 minute per day changes. More research is needed. Link to comment Share on other sites More sharing options...
The Former Fiend Posted November 25, 2013 Report Share Posted November 25, 2013 I read about this in New Scientist a month or two ago in an article framed around depression. The results sound very impressive... but I agree that more research needed before getting too excited. 1 Link to comment Share on other sites More sharing options...

etardnow Posted November 25, 2013 Report Share Posted November 25, 2013 iirc i think odisa had some positive results using tdcs but it is temporary(with usage) Link to comment Share on other sites More sharing options...
onedayillsailagain Posted November 25, 2013 Report Share Posted November 25, 2013 Yes tDCS has been, up to now, the most effective therapy for attenuating my symptoms, predominately depersonalization and cognition. I gave it up because the device I made is a bit of a hassle to apply, and indeed benefits are rather transient.This was at 1.5mA for 20 minutes, anode at F3 and cathode at Fp2 I believe.

Jay1 Posted November 25, 2013 Author Report Share Posted November 25, 2013 Did you make a DIY kit or buy one from somewhere? Link to comment Share on other sites More sharing options...
onedayillsailagain Posted November 25, 2013 Report Share Posted November 25, 2013 DIY kit. You can read of my experience starting here. Link to comment Share on other sites More sharing options...
Jay1 Posted November 25, 2013 Author Report Share Posted November 25, 2013 I wonder if trying anode at O1 and/or O2 (visual cortex) would benefit? Have any users had a qEEG test? can they remember where the over excitation was in their scans? Link to comment Share on other sites More sharing options...
hppd33 Posted November 25, 2013 Report Share Posted November 25, 2013 I wonder if trying anode at O1 and/or O2 (visual cortex) would benefit? Have any users had a qEEG test? can they remember where the over excitation was in their scans? Yes. I did rTMS for DP/DR and before that i had a qEEG. From the qEEG (we) could read i was nervous, everytime something new with neon stuff or weird questions came up, it was readable.. For me i didnt made any difference because i was on klonopin and lots of other meds. The good news is, there are people in (my) group of test persons, who dont have anxiety anymore for DP/DR.. for HPPD it didnt work(me.) My thoughts are if you have DP/DR and depression and you dont take meds, its possible it could work.. You will need to have patience and money though. It was in The Netherlands.

onedayillsailagain Posted November 25, 2013 Report Share Posted November 25, 2013 I would think, given the theory of hyperexcitability, that cathode over occipital regions would be of more merit.However, nothing is absolute, and it may be that anodal stimulation would be beneficial.I haven't tried it myself yet, though I remember I've added quite a few articles on the subject over at "Research Articles". You might have to click " load more topics" as it was a while back. Link to comment Share on other sites More sharing options...

biohacker Posted April 1, 2023 Report Share Posted April 1, 2023 Long time since this thread went dormant. But there was a promising article on this from 2022: Frontiers | Pathological Delta Oscillations in Hallucinogen Persisting Perception Disorder: A Case Report (frontiersin.org) "Two sessions of cathodal (inhibitory) transcranial direct current stimulation (tDCS) over 30 min attenuated visual hallucinations and occipital delta activity by approximately 60%. The response persisted for over four weeks." The process was as follows: The electrodes were placed perpendicularly to the midline, such that the cathode was centered to electrode position Oz and the anode was centered to position Fpz according to the international 10–20 system. Two 30-min sessions of tDCS each were performed, separated by an intermission of 30 min. EEG was obtained immediately before the first and after the second session of tDCS. I'm about to try it this afternoon. I've also done standard theta-burst rTMS over the dorsolateral prefrontal cortex, to great effect. Lots more energy and fewer mood impairments. A foot in the door to trying other things. Following this tDCS experiment, I'll try photobiomodulation. 2 Link to comment Share on other sites More sharing options...
Jay1 Posted April 2, 2023 Author Report Share Posted April 2, 2023 That's a great find! I look forward to hearing how you get on Link to comment Share on other sites More sharing options...
biohacker Posted April 2, 2023 Report Share Posted April 2, 2023 No results with tDCS on visuals for me, but no reason why it wouldn't work for someone else! I did experience flickering in my field of vision, so something was happening. I should also mention that my visuals aren't the same/as extensive as others -- I have brightness and starburst patterns, no trails, and very little snow. So perhaps there are different pathway issues for different visual problems. It's still incredibly irritating and seems reflect some kind of cascade throughout other brain regions. Next, I will try photobiomodulation (the Vielight Neuro Duo 3 + X plus), which acts on the default mode network in the gamma and alpha wave range (+ the X-plus works on the occipital lobe). Hallucinogens act on the default mode network, and, if you found your way to this thread, you would also know that (some believe) HPPD is also an expression of damage or disruption to the occipital lobe, causing hyperexcitability. The combination of these two devices by this manufacturer is worth exploring. Lots of research on the Vielight site validating the tech and the approach modulating the outer cortex. It costs about 3K. I'll use it for awhile and can report back. Then, if I can find the money (~6K) I'll also try the PoNS device. PoNS works to stimulate the midbrain (the internal brain structure) through the tongue, and it has made a miraculous difference for folks with traumatic brain injuries and MS. That includes improvement in visual processing, balance, tinnitus, and emotion regulation, depending on the rehabilitation protocol. It's theorized that PoNS does this by repairing interneurons. If you've done your reading, you'll know that one theory re: HPPD is that it reflects damage to interneurons, causing hyperexcitabilty in certain parts of the brain; hypoexcitability in other parts, including the prefrontal cortex. Between those two technologies, I will have tried acting on both the internal and the external structures of the brain. Link to comment Share on other sites More sharing options...
