Ghormeh Sabzi Posted March 2, 2012 Report Share Posted March 2, 2012 So we know MRIs and EEGs normally come back normal in the case of HPPD. Are there any kinds of tests that may show abonormalities? fMRI? qEEG? SPECT? Anyone had a test that has shown anything irregular? Link to comment Share on other sites More sharing options...
vivienne Posted March 3, 2012 Report Share Posted March 3, 2012 I have not, but I believe a qEEG will show something if read by the right specialist, so I've never had one myself.. Link to comment Share on other sites More sharing options...
OliverW Posted March 12, 2012 Report Share Posted March 12, 2012 http://www.ncbi.nlm.nih.gov/pubmed/11566431 A study done by Dr. Abraham shows that brain wave coherence is actually reduced for individuals with HPPD... So EEGs will show irregularities in synchronization of brain waves. Not sure what frequency (alpha, beta, mu, etc.) but if you are a patient of Abraham you could probably ask him yourself.

vivienne Posted March 13, 2012 Report Share Posted March 13, 2012 Thanks, Oliver. The article does prompt me to wonder what falls under the spectrum of "within normal range" for someone reading the results but not looking for HPPD or not knowledgeable about it. Mine (EEG) was done to look for seizure activity I had (through acute illness not chronic), though found not to be classic epilepsy. I do know I have HPPD but I've not been formerly diagnosed by Dr. Abraham and doubt I could get to see him in the near future. Is there anyone else reading who had normal EEG's? I thought this was common-place on the old forum but I could be wrong! Link to comment Share on other sites More sharing options...
Ghormeh Sabzi Posted March 18, 2012 Author Report Share Posted March 18, 2012 I was under the impression normal EEG's were common too. I'll get my results soon and let you know what it says. I wonder if a PET or DaT scan would come out as abnormal. Link to comment Share on other sites More sharing options...
415_stylee Posted March 19, 2012 Report Share Posted March 19, 2012 I have done two EEG´s, one CT and one MRI. The EEG´s revealed nothing abnormal, but the MRI detected a scarring in the right ventricular wall in the brain (most surely not related to HPPD in any way). I´m still trying to get a qEEG done, which seems to be the only method of detecting abnormal HPPD brainwaves. But anyway, I finally have a HPPD diagnosis. This due to the unwavering persistance and nature of my visual disturbances (had it for 6 years now). And of course, the drugs that caused them.
