Dr Bessel from the Body keeps score author is the best one to explain the conversion disorder without mentioning FND. I'll leave it to the neurologists and researchers to explain the neurological details.
I like to use Maslow's Hierarchy of needs to visually explain the treatment, but to show the complexity of the treatment. I like oversimplifying complicated things in FND.
The bottom line of FND treatment is to maintain safety: physically, emotionally and mentally= TLC (tender loving care).
If basic needs are not met the body sends a distress signal whether through hormones or FND symptoms.
For example, when we are in pain right, we either rest, take meds, or get professional help? We and people around us, respond better to physical symptoms rather than psychological/emotional pain.
This is to answer why one size, doesn't fit all. Our needs are different. So I like to use principles of Maslow's idea.
How the principles of the treatment works:
1) Applying Maslow's hierarchy of needs in reducing distress signals in the body.
2) I use neuroplasticity to also show how it takes months to years to reduce relapse of FND. Pacing helps to better rewire the brain. Neuroplasticity is a way to maintain and prevent relapse from FND.
I cannot fully say that a person can fully recover from FND. Our needs are complex.
Plus, not enough research data to compare. However, there are other disorders with similar somatic symptoms as FND, which Dr Bessel has compiled. There are others, but his were a lot of longitudal data.
Why it is strongly linked to emotions? When we keep pushing our feelings down. It becomes an unresolved trauma. "Inescapable shock" (the body keeps score) is when our body relives the stress and doesn't know how to shut off the stress signals. The body thinks/learns (neuroplasticity) we are still in danger.
The accumulated stress has to go out somewhere? The body needs a natural way of healing.
3) Interoception is a way to assist in paying attention to internal signals.
Sometimes it requires a Reiki, trauma based physiologists, somatic psychotherapists. Specialists with knowledge of mind and body connection.

I just like to connect the dots.
I was curious why medical professionals like to ask certain questions, why some of their words have sometimes super powers of healing, why they say be gentle with yourself, why they say to distract yourself, why yoga helps, meditation, deep breathing, why seeing mental health professionals is needed or medications, or take this medication. I was curious why temperature flares up FND or sounds and lights can be awful to a person with FND. Finally, why it was said to be the most second diagnosed in the neurology department?
I was very curious and always asked the why, what, how, When, where. Which includes the connection of emotions to the mind and body.
I was quite appreciative of how people with FND share their personal stories before and after diagnosis. What medical professionals say to them, how their body responds. I was curious about similarities of treatments, body responses and how people got better. It helped me to start looking for patterns.
So this is one way of explaining FND and treating it.
