[|Human|] My sister is 66 years old, no heart problems, however she has recently been diagnosed with dementia. She recently started fainting and everything looks bright to her and she follows with a headache. She has been checked out by a cardiologist, had ct scans and mri of her brain. Nothing has showed up in any of the tests but she continues to have this problem. Any idea of what could be going on with her?
[|AI|]  Hello! I read your question and understand your concern. I think it may be migraine associated with aura. The normal MRI findings are in favor of this diagnosis. But the age is a little exceptional for primary migraine. Another possible diagnosis in this case would be partial Epilepsy. If I were her doctor I would perform an EEG to rule out Epilepsy. If everything is normal it is probably migraine. I would also recommend a regular measurement of blood pressure during standing up and sitting, because orthostatic hypotension can give such troubles. Although less probable as she has been consulted by a cardiologist. Hope to have been helpful! Thank you for using Chat Doctor! Best wishes Chat Doctor.
