Around 5 years ago I had a sudden onset of seizures, movement disorder, gait and balance issues etc. I went to A&E twice, both times I was told it was 'conversion disorder' and was sent home with a link to the NeuroSymptoms website. I was having trouble speaking and emotional liability. Neurologists just immediately saw my history of mental health issues and made assumptions.
I deteriorated for years, including my mental health and cognitive function. No GP took me seriously as I had this diagnosis.
I am now under a new neurologist, and I have the real diagnosis of been suffering with adult onset rheumatic fever, which caused Sydenham's Chorea- i.e the symptoms the 'conversion disorder'.
I had been to my GP complain of joint inflammation and chest pain, about a month before the sudden onset of symptoms. But I was told it was 'fibromyalgia'!
I am so angry that I was immediately diagnosed with this condition, without exploring further causes. FND should be a diagnosis of exclusion, and can also be co-morbid with an underlying neurological condition.
I'm not saying that FND doesn't exist, but I'd urge anyone with this diagnosis to think about any instances of inflammation or illness. And please get a second opinion if you feel you need to.
