Photosensitive seizure-like episodes after hemiplegic & chronic migraine, anyone experienced similar?
Hi everyone,
I’m posting because I’m trying to work out whether what I’m experiencing sounds familiar to anyone here, especially people with focal seizures, photosensitive epilepsy, or seizure/migraine overlap.
Quick background: I developed severe ME/CFS as a teenager in 2011/2012 (following a concussion and viral infection) and became extremely unwell for years. I lost the ability to walk between 2012–2019 and was bedbound for a long time. Over the years I improved massively with pacing/rest/time and regained a lot of function, although I still deal with chronic migraines, autonomic symptoms and fatigue.
My migraines used to mainly happen around storms/weather changes, but over the last couple of years they became chronic and I feel like I’m in a constant migraine state.
I’ve also had repeated episodes, usually in the evenings while watching TV, where I suddenly get palpitations, feel fearful or detached/spaced out, and sometimes fall or lose awareness briefly. I had cardiac tests to rule out any heart issues for my palpitations and dizziness, all game back boringly normal.
Then in April this year I had what doctors believe was a hemiplegic migraine. Sudden left sided weakness/limp, severe neurological symptoms, extreme light/sound sensitivity etc. MRI/CT were clear. Since then my nervous system has felt extremely sensitive.
The biggest thing has been severe sensory sensitivity. Shops/supermarkets became overwhelming, TV motion started making me feel strange and spaced out, and bright lights became unbearable.
Then in May I started having repeated seizure-like episodes, often clearly triggered by light or visual stimulation. The first major one happened while watching TV. Since then I’ve had episodes involving:
eye rolling/fluttering
lip smacking
reduced awareness/unresponsiveness
left facial twitching/spasms
feeling very clammy/confused afterwards
coughing/shaking after coming round
I ended up in hospital because they were happening repeatedly. Overhead lights repeatedly triggered them there too, including during a CT and when doctors shone lights in my eyes. Removing my sunglasses could provoke symptoms almost instantly.
Routine EEG captured dizziness and left facial twitching but showed no epileptiform correlate. There was intermittent temporal/posterior slowing but no epileptiform activity. Neurologist currently thinks these are more likely non-epileptic/dissociative attacks rather than epilepsy, this has all felt quite confusing as I don’t feel there’s a mental health connection, I also feel perfectly relaxed when these come on, rather than distressed in any way.
I’m struggling because some aspects feel VERY seizure-like to me, especially the impaired awareness/lip smacking/eye rolling, but the strong sensory trigger pattern and clear EEG seem to point away from classic epilepsy.
Has anyone here experienced:
focal seizures triggered mainly by light/visual overload?
normal routine EEGs despite convincing symptoms?
migraine evolving into seizure-like episodes?
attacks with automatisms/lip smacking but no EEG correlate?
severe post-migraine sensory hypersensitivity?
Also interested in whether anyone found things that genuinely helped reduce attacks or calm the sensory overload side of things.
I’m also waiting for a longer EEG/video EEG.
Thanks :)
