Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Can visual processing issues stem from 1) respiratory infection or 2) stress and anxiety?I am 30F, relatively active lifestyle, diagnosed with ADHD and treating it using Vyvanse and regular therapy.I am on the tail end of a two-week cold. Still have a bit of congestion and fatigue but no sore throat or cough etc.Something I've noticed over the past couple weeks/in the past is that I feel like I have difficulty processing visual information. E.g. if I'm walking in a forest, the amount of visual information seems overwhelming. I can't really "see" what's in front of my unless I really stop and focus on one thing at a time.My last eye tests showed I had 20/20 vision and I have no issues reading on screens or seeing things far away, it's just that when I'm presented with a lot of visual information, I have issues processing it all.I've also notice this happen in the past when I've had depressive episodes. Does this sound like an actual issue with my eyes, or could it be linked to my mental state?. ### Response: Simple answer is yes. Fatigue and illness affect sensory processing and cognition, usually transiently. That's a good thing, since it forces you to rest, slow down, let your body recover. The more complicated question is whether there's something different about your experiences as compared to people without neurodivergent states.Your description suggests that you might have visual snow, though maybe you are just overwhelmed with information during higher stress?.
