Got my neurology appointment today in light of briefly being unable to walk forward a week or 2 ago. The brain's all good for the most part. The benign brain cyst hasn't really grown so it's just a matter of continuing to monitor growth once or twice a year. The lack of growth and the location both make it impossible for it to have an impact of the movement like that.

The explanation for what happened was pretty weird but also kinda fascinating imo if you're into medicine or just like to know how things work, particularly your brain.

Brief recap:
I had that issue about a week or 2 ago where my legs suddenly refused to walk forward and caused heavy tremors, therefore restricting the ability to move forward. This lasted for several hours. The baffling part was that I had no issues walking sideways or backwards during that brief period. In addition to that, if another person touched me or if one of my hands touched a part of my upper body, my brain magically allowed me to walk forward again without any tremors preventing the movement.
Apparently the brain suddenly refusing to perform a particular action is a "relatively" common issue and not entirely restricted to people with some form of epilepsy. Normally it's caused by intense stress/trauma though so idk why my brain randomly decided to pull a trick on me.

Actual explanation:
The neurologist described this as "functional tremors", referring to the brain refusing to perform a specific action rather than a more generalized or random form like in Parkinson's Disease.
Due to some kind of trigger, your brain basically gets fried but not all the way. To more or less sum up what happened in my case, it was like the forward button on the controller stopped working but the other buttons remained intact.
As for why the part of someone else's or my own touch magically allowing me to perform the action of walking forward again, it's because the brain receives a slightly different impulse in that case. Here's a very simplified version:
"Move forward" -> Error -> Brain denies request to carry out the motion -> Heavy tremors are caused to prevent attempts to perform the action
"(Condition) + Move forward -> No error -> Brain approves the action
Hence why the tremors immediately started back up as soon I or someone else stopped touching me. That removes the conditional aspect so the movement immediately stops working.

The neurologist said it's likely that attaching other kinds of conditions to the forward motion would've probably bypassed the brain malfunction as well but the touch condition was just the first thing I happened to stumble upon by trying various movements and combinations.


If for some reason the brain decides to malfunction like this, you're kinda screwed until it dissipates. The malfunction lasting about 6 hours or something was relatively long for this kind of thing.
Certain medications can lessen the impact but it's a similar principle as medication for Parkinson's Disease; just numbing your overall brain activity. Because functional tremors has such a short duration and came with a bypass method, it would've been pointless to take a benzo or something to numb my brain.

So that's how it works.
If anything, the strange part is that I didn't have any obvious trigger to cause this. Like the neurologist said, anyone can experience this and it's not specifically related to epilepsy but it's normally the result of your brain getting partially fried due to an overload of stress or trauma. I don't really consciously feel stress so it must be something subconscious, which is obviously harder to pin down and treat.
