<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, My father is 70yrs old and was recently admitted in hospital witChatDoctorplaints of low sodium 120. He was then discharged in a few days once his sodium levels were 132. But he was depressed and had delusions. Consulted a Neuro and he said he is having mild dementiaalzhimers. He initially gave aricept, nexito plus and vit b12 tablets for a week...nothing improved  <response>: Hello, dementia is a chronic condition that impairs the functional capacity of the patient, causing memory loss and other deficits as the disease progresses. I cant - obviously - explain your fathers condition without having examined him but Im sure the neurologist is more than capable to handle such situations. After dementia becomes evident, you cant expect a great improvement, and you cant expect him to get back to normal. The Chat Doctor. Despite that, you should discuss how hes going with the neurologist. The neurologist should re-assess your father and perhaps modify his treatment regimen. Kind Regards!
