What causes episodes of pass outs, nausea and weakness?
Patient: I have been feeling extremely exhausted and having episodes where I feel like I m gonna black out usually when I m walking. I also have been feeling really weak and have had a headache for three or four days now. I find it hard to find words at times. And feel nauseous but haven t vomited. I m taking my medications regularly. Just feel horrible. Doctor: Hello,   You need a detailed neurological examination. This would be followed up by a brain scan to determine the cause of headache and word finding difficulty.   Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Sudhir Kumar, Neurologist
