This problem is deeply connected to the latter because what happens if your brain doesn’t have enough nutrients to work correctly? It will also become sluggish, and your memory will be significantly impaired. In advanced cases of liver damage, there’s something called hepatic encephalopathy. In this state, the liver stops metabolizing ammonia. Similar to bilirubin, this substance builds up in the blood and enters your brain. High ammonia levels cause inflammation and trigger several chemical processes leading to worsening neurological symptoms. They start as memory issues but may worsen if you don’t look for medical help.
