### input:
My father in law, 70 yr old, very active and fit person residing in India. since a week of so he has been losing memory of day to day activities. just realised that he is bed wetting . we have admitted to the hospital. his blood pressure is normal. Still waiting for neurologist to give us diagnosis. Medical conditions: Cholesterol & diabetes is under control with medication from the last health check that was done few months ago. I hope this is not a sign of dementia . Could you kindly advise what other conditions could cause the same.

### output:

Thanks lot for posting your questions in this website. The problem in elderly individual is generally difficult to handle, and a given medical problem can have multiple causes. Regarding your father, if you are very sure that the problem has started very recently, a medical condition called as delirium needs to be ruled out. This is a medical condition which may present similar to your father, provided that the onset of illness is of short duration. As the causes of delirium are so many, your father would require blood tests to rule out any infections, altered liver functions, kidney functions, CT scan or MRI scan of brain to rule of any tumor/stroke which may explain his problem. The second part of the story is that this illness might have started earlier in a less severe form and might have worsened now. If this is true, a possibility of dementia is high on the card. My advice will be to get the blood tests, liver and kidney function tests, serum sodium, thyroid function including MRI Brain. If all these tests are inconclusive, he may be subjected to a detailed neuropsychological evaluation to see if he has dementia or not, and we can manage accordingly after establishing the diagnosis. The third part of the story in these types of cases is that a single patient can have both and if delirium is treated properly, he gets back to the previous state. Hope this will help you your father is in India, they can contact merest wishes
