Hello Linsky,Spasmodic Dysphonia (SD) is a neurological disorder that involves involuntary "spasms" of the vocal cords, causing interruptions of speech and affecting voice quality. SD can cause the voice to break up or to have a tight, strained, or strangled quality. In this video, it doesn't appear that any "voice" ever reaches your vocal chords.
I also watched all the other videos on your website. It certainly does appear that you have some very unusual symptoms. While you were unable to speak in this video, your voice sounds completely normal in the other videos, which is not typical of SD.
The videos of your "neck lock" and "whiplash bent back" could indicate some sort of dystonia, but also appear random and intermittent -- as an example, the video of your "speech deficit" doesn't show any neck or back symptoms, while the video of your "neck lock" doesn't show any speech or back symptoms, etc.
Your neurologist's diagnosis of "psychological" must be very frustrating. Unfortunately, many doctors resort to this diagnosis when they are unable to figure out what is wrong with someone. Spasmodic dysphonia was once thought to be psychogenic. Fortunately, there is now a lot more awareness about SD among the medical community.
Regardless of the exact cause of your symptoms, the support and guidance of a mental health professional can still help you deal with these challenges. Many people find that it is very beneficial to seek psychological counseling when they have illness or injury, especially one that is difficult to diagnosis and/or treat.
Best of luck to you.
