Thank you for this fine article, Samantha. I would like to clarify this point: “However, these symptoms are often misdiagnosed as a functional disorder or “relapse” back into mental illness.” I do not know how often antidepressant withdrawal symptoms are misdiagnosed as a functional disorder (Functional Neurological Disorder or FND). I cannot recall any incidences of this on my Web site, which is based in the US, with a majority US membership. In my opinion, misdiagnosis of withdrawal syndrome as “relapse” by GPs or psychiatrists is far, far more frequent — near total. Most likely, this misdiagnosis is so pervasive, it precludes most people suffering from withdrawal syndrome from advancing to see a neurologist. It takes a stubborn patient to get to the neurologist specialty level. Of those on my Web site (including myself) who have taken their psychiatric drug withdrawal syndromes to neurologists, the most they get is a shrug rather than a diagnosis, and maybe a referral back to psychiatry. A diagnosis of FND for people with psychiatric drug-induced movement disorders may be misguided but it may be a portal to the best treatment these people can get, since psychiatry is notably blasé about those movement disorders. The danger in not taking drug withdrawal syndromes into account in a FND diagnosis is that psychiatric drugs are one of the treatment options, and when applied to a nervous system already sensitized by drugs, may cause further damage. There is no doubt that in this overdrugged world, training in recognizing iatrogenic syndromes needs to be introduced and even emphasized for neurologists. To sum up, from what I’ve seen, a misdiagnosis of “relapse” for withdrawal syndrome is a clinical error occurring far more frequently than a diagnosis of FND. FND is a possible but not major withdrawal syndrome misdiagnosis.
