[|Human|] Yes. I have a friend whose son in 2004 completely quit eating for 180 days not much water intake either. He has since been eating well and has been encouraged to eat other things.He at one point was in the hospital for a short time but then his mother took him home. He was in the Psychiatric Unit of the hospital. Now he has a girl friend and she is asking question. At this time he is getting his strength back and going to the gym once a week riding the elliptical and the tread mill at great paces. When and even before he seems to be having trouble bending his knees and is not stable when walking alone has to use a walker. I am assuming that much of this has been caused from not having the nutritional diet he needed for 180 day. They want to have him have a brain scan or even cat scan of his head. Is this a recommended way to go?
[|AI|]  I appreciate your query on Chat Doctor. Based on the history I would suggest that diagnosis of Depression is clinical and not based on CAT or CT scan or any brain scan at present.Moreover, patients of depression will have a (mostly)normal CT/CAT scan. The symptoms you have mentioned may be due to some other brain disease (Neurological) in that case CAT/CT scan or MRI brain is helpful. I hope you find this helpful.
