Welcome to Ben’s Friends.
Firstly, don’t be too worried about your English, you’re doing OK. Even people who have English as their first (and only) language can still have issues when it comes to expressing themselves with the written word (Well, I do anyways )
As for your question “Does gadget stimulation bad for AVM?”
We have ‘regions’ of the brain that are aligned with particular functions. For example the frontal lobe, behind our forehead, is considered as the area of decision making.
BUT it does not work solely on it’s own but rather in collaboration with other parts of the brain such as memory. So another example is we make a decision to touch the stove, but our memory reminds us ‘HOT’. So here we are using 2 differing areas of the brain and that’s even before using the physical aspect of movement involving yet other portions of the brain. All of these brain structures need to communicate with each other and all of these structures have their own blood supply. With an AVM this blood supply is altered, but which supply alters which part and to what extent? And this question is very much open to interpretation. Each dr can have their own ‘opinion’ of the specific impact.
No two brains are wired in exactly the same way, so to be saying that any AVM is going to have an exact effect on an exact structure is near on impossible. Depending on both the exact location and size, symptoms can vary massively. An AVM may affect blood flow, but it can also put pressure on other brain structures, so although the affected vessels may not directly correlate with the blood flow to your visual cortex, the pressure from the AVM could well have an effect on your vision.
Now I say all of this from my own experience. My situation is not AVM related but I have a growth within my brain. It is not directly related to my vision but it most definitely, at times, affects my eyes. I have had dr’s look at my scans and say ‘There’s no affect…’ but I have also had dr’s say the exact opposite. There is not a lot of space within our skulls and we need a balance between blood, brain matter and cerebral spinal fluid. If one of those things is out of balance I become symptomatic. Now, add tiredness, stimulation, light intensity to that and the effect/symptoms can be huge. I have learnt that despite a dr’s opinion/view I have to manage it all for myself. Be that by time management or limiting my screen viewing time or by medication or by my activity limits. It can all have an impact on my symptoms. And no 2 days are ever exactly the same.
