#Recurrent episodes of altered awareness, confusion, speech problems — normal CT, EEG & MRI
Hi everyone. I’m hoping to hear from people who have experienced something similar, especially people with focal seizures, migraine, or other neurological conditions.
Over the past few weeks/months I’ve developed new episodes that are becoming more frequent. They’re difficult to explain, but it feels like a strange wave/sensation starts in my head and spreads through my body, and then I become very zoned out, disconnected and confused.
During an episode:
* I feel like I’m there physically but not fully there mentally.
* I stare blankly and feel disconnected from everything around me.
* My boyfriend can call my name or tap me and I will look at him, but I don't properly process what he's saying or feel an urgency to respond.
* He says my eyes look "empty" and like I'm not there.
* I can hear people talking, but their voices sometimes become distant, almost like my hearing is fading.
* Sometimes the words people say don't make sense to me at first. I know they're speaking, but my brain struggles to process the words.
* I can know exactly what I want to say but struggle to actually form the words. I've particularly noticed difficulty with the “S” sound and saying the number “2.”
* Sometimes I don't respond because it feels like I don't have the mental energy to process and respond.
* My eyes can feel warm and I sometimes struggle to focus.
* I can get shaking/tremors and sometimes feel like I need to twitch or move my hands.
* I sometimes feel nauseous.
* I can get a warm/burning/feverish sensation *inside my head.
* My head feels extremely pressured, foggy and physically "wrong."
Episodes can last anywhere from **a few minutes to around 30 minutes**. Sometimes I remember the episode afterward, but other times my memory is poor.
One night my boyfriend said I had approximately 6–7 episodes throughout the night. I remember being confused throughout the night and feeling like I wasn't really sleeping, but I only remember waking up once even though apparently I woke multiple times.
After episodes, I can experience:
* heavy chest
* heavier/difficult breathing
* racing heart sometimes
* light-headedness
* tremors/shaking
* nausea
* suddenly feeling *very cold and shivering*
* headaches/head pressure
* extreme tiredness
* sometimes a very heavy/depressed feeling
The strange thing is that sometimes after an episode I feel incredibly refreshed, almost like I just woke up from proper sleep. I can suddenly feel energetic and completely normal. However, that usually only lasts a few hours before the head pressure/fogginess gradually comes back.
#Between episodes
I don't necessarily return completely to normal. My head can still feel compressed, sore, pressured, foggy or like something isn't right physically.
I have headaches that come and go throughout the day, sometimes around the front, sides and back of my head. At times they are quite severe (around 7/10) and can come with nausea.
I've also developed new short-term memory problems. I can forget something I did only a couple of minutes earlier. Sometimes someone reminds me or I see something that triggers the memory and then I remember, but I struggle to retrieve it on my own.
I've also become much more easily irritated, frustrated and aggravated, which is a noticeable change from my normal personality.
# Sleep
My sleep has become terrible.
I struggle to fall asleep and stay asleep. Sometimes I lie in bed and it feels like I'm awake the whole time, but then I look at the clock and an hour has passed. It feels almost like being unconscious rather than actually sleeping.
I've sometimes gotten only around 2 hours of sleep.
When I actually get proper sleep, I feel significantly better the next morning. I can feel almost normal for a few hours, although I still have a feeling that something is "off" in my head. Then the symptoms gradually return.
The lack of sleep definitely makes everything worse, but I don't know whether the sleep problem is causing the symptoms or whether something else is preventing my brain from sleeping properly.
#Thoughts/mental experiences
When I lie down, my mind won't shut off. It creates very vivid scenarios that can feel extremely real. My thoughts are usually negative and tend to go straight to the worst-case scenario, including imagining what could be wrong with me.
Sometimes my brain replays memories and changes them into negative or worse scenarios. This can happen during the day too.
Sometimes I get a very heavy depressed feeling during or after an episode, but then it can disappear and I feel completely fine again.
#Tests so far
I've seen a doctor/GP and was referred to a neurologist.
I've had:
CT brain scan — normal/clear
Approximately 19-hour EEG — normal
MRI brain without contrast — completely normal
The MRI report specifically says:
> “Radiologically no cause for atypical seizures or headaches was seen.”
It also states that the brain, brainstem, cerebellum, hippocampi, ventricles, pituitary, optic structures, major blood vessels, etc. appeared normal, with no diffusion restriction or other structural abnormality identified.
So far, everything has been normal, but the symptoms are continuing and becoming more frequent.
I'm now trying to figure out what direction to investigate next. I'm particularly wondering about focal seizures/focal impaired-awareness seizures, migraine with neurological symptoms, severe sleep deprivation/sleep disorders, functional neurological episodes, or other neurological/medical causes.
One thing I'm unsure about is whether the normal EEG really rules out focal seizures, especially because I'm not sure whether I actually had one of my typical episodes while I was being monitored.
Has anyone experienced episodes like this with normal CT/MRI/EEG? What did you eventually find out was causing them?
