[|Human|] Dear Sir, My mother is suffering from Depression since last 5 - 6 years and we are getting treatment from a Neuro psychiatrist.  She is continuing medicines since last 5-6 years.  She is alright all the times when she is taking medicines.  But sometimes when she heard any mishappenings she got in deep thinking & then got disturbed and start talking and she dont know what she was telling or doing.  She cant sleep for 2-3 days continue not even in night.  In July 2011 she also suffered from the fever Chikangunia and her complete body is paining & when we consulted a doctor, he has given three injections for relief from pain.  After that she is much more depressed and feels weakness.  Also there is one problem that about 2 - 3 times in a day her when she stands up and do something her body starts shivering  and she fells down for 1 - 2 minutes and after that she is ok.  My mothers age is around 56 years and weight about 82 Kgs.
[|AI|]  You have not described about medicine details and a other ailment she is suffering. Her weight is somewhat more. Considering your I can describe few reasons for her problem. First one is if some medicines are causing postural hypotension mean slow blood pressure, she feels dizzy and tremors as lack of blood supply to brain for a moment. Another reason she may have some neuropathic changes which may be due to relative nutritional efficiency in depression like methylate, it b12. Seeing her age and weight it may be due to knee problem. Ask her treating doctor to evaluate cause by examination of her.
