Good questions from Ghormeh Sabzi. I have spoken with Dr. Halpern myself, in addition to doing my own reading on the subject. I have treated a handful of patients with HPPD - there are just not that many patients that seek me out for treatment. Visual and psychiatric symptoms have both been improved. I treat HPPD, as well as help patients learn to deal with it. Part, but not all of the treatment for HPPD, is helping patients learn to deal with it. I do not prescribe benzodiazepines. I detox patients from this class of medication, and see the horrible withdrawal syndromes that they experience.
