Today is FND Awareness Day and as someone living with this condition, I wanted to take a moment to share what that means for me.
I received my official diagnosis six months ago, but looking back, the signs had been there for four years. Those six months have changed my life drastically, and I think one of the most important things I can do now is help spread awareness.
Functional Neurological Disorder is a condition where the brain doesn't send and receive signals to the rest of the body correctly. It can mimic conditions like MS, epilepsy, Tourette's, and Parkinson's, which is why it's so commonly misdiagnosed, sometimes for years.
The symptoms can include:
Movement issues such as tremors, muscle spasms, dystonia, and gait difficulties
Functional seizures (also called non-epileptic or dissociative seizures), which can involve long periods of unresponsiveness or fluctuating awareness
Sensory changes, numbness, tingling, vision loss, or tinnitus
Speech difficulties, brain fog, memory loss, and trouble concentrating
Chronic pain, severe fatigue, sleep disturbances, dizziness, and bladder/bowel dysfunction
I experience all of these to some degree, every single day, but no two days are ever the same. It's something I'm still learning to live with, and it has been a huge adjustment.
FND doesn't have one single cause. It can develop from a mix of neurological factors, disruptions in brain function, physical illness, injury, stress, or emotionally challenging experiences. The exact causes are complex and still not fully understood, which makes it all the harder to explain to others.
What surprises many people is that despite being classed as a rare disease, FND is actually one of the more common reasons people attend neurology clinics, with some research suggesting that around a third of outpatient neurology appointments involve patients reporting functional symptoms. Yet the mechanisms behind it remain poorly understood.
For me, it can strike without warning. One evening I had a cluster of seizures with no identifiable cause, no explanation on an MRI, nothing. That's the reality of living with FND.
There are lots of misconceptions about FND such as
Myth: It's all in the mind / it's a mental illness. Fact: FND is a neurological condition. While it can occur alongside anxiety or depression, it is a distinct, physical issue with how the brain functions.
Myth: There's no visible damage, so the symptoms can't be that bad. Fact: Think of it like a software malfunction, the hardware may look fine, but the system isn't working properly. The symptoms are very real and can be severely debilitating.
Thank you for taking the time to learn a little more about FND. Awareness matters for those of us living with it, being understood makes all the difference
