Help me to understand

[kynerer]

Hello everyone, I'm sorry, I'm writing through a translator. Please answer 3 questions. 1. To what extent is HPPD an independent disease? After all, people who have never used drugs can also experience DPDR and see visual snow. 2. Why did a mixture of paracetamol and aspirin, during a hangover, completely remove my brain fog for a while? What happens in the brain during a hangover? Is this due to increased cerebral circulation? For this reason, dizziness can occur, which is a common symptom. 3. As far as I know, the only cure for the brain is neuroplasticity and adaptation to new conditions. Has anyone taken drugs for people with stroke? I know that there are many people here who understand this topic better than me, so I will be glad for any answer.
