Not from UK and never had it, but are you on antidepressants now? Which ones and at which dosage? SSRIs don't cause it unless you're on exceptionally high doses -- I've heard this only from the SNRI Effexor, but I suppose it can also happen with SSRIs. When there's too much serotonin floating around in your brain it starts to affect dopamine, and it's dopamine that causes TD. If that's in fact what it is, it's supposed to, anyway, go away if you stop taking the medication, or in the case of very high doses on an SSRI, taking a lower dose. I would guess it's also possible to get it from recreational drugs, as most of them also affect dopamine. It's mainly found in those who are on antipsychotics. There is a medication advertised on TV in the US that I think is a new drug that purports to mitigate TD from medication. Of course, that means taking another medication. As for worry about permanent brain or organ damage, don't know about the brain damage -- don't know anyone has found that. What they have found is not technically brain damage, but the inability of the brain to work naturally anymore because of long-term use of drugs that alter how the brain processes neurotransmitters naturally. Alcohol, of course, can do that as well, and I'm thinking it might also be able to cause TD. But again, this is something that they say goes away if you stop taking the drug or med that causes it. Have you talked to your psychiatrist about that? I know they can be pretty dense when it comes to drug side effects. You have some very good academic psychiatrists, by the way, teaching in England who have led the way on the dangers of taking antidepressants. I wish I could remember the names, but they've probably talked about this because they've talked about so much and is the reason we know a lot of this now. One of them is the reason withdrawal from stopping these meds came out into the open, so if you can do some Googling you might find this one fellow and he might be a valuable resource for you there. But you do need to make sure a doctor confirms your hypothesis, because other things can also cause this, such as Parkinson's and Parkinson's like syndrome. For the rest, I can be of no help.
