[|Human|] My dad has lung cancer and just in the last two days he has become very confused and cannot put sentences together, cannot feed himself, walk, or go to the restroom on his own...does this appear to perhaps reached his brain or could this be from the strong pain patches that he has been on for just a few days now? Thanks
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. There are few causes for altered mental status and confusion in lung cancer patients. 1. Spread of tumor in brain.2. Electrolyte imbalance especially hyponatremia (low sodium).3. Acute psychosis from the fact of having incurable disease. So get done MRI brain to rule out brain metastases. Get done S. Na+ to rule put hyponatremia. If both are normal than consult psychiatrist to rule out acute psychosis.
