What Causes Hypersomnia, Lack Of Energy And Anemia In An Elderly Woman?
probably not any deficiency
Detailed Answer:
Hello,
although any kind of deficiency may initially have no noticeable effect on the complete blood count, it's rather doubtful whether such a disorder would have caused symptoms. A high MCV (particularly if her previous MCV were much lower) may indicate folate or B12 deficiency but it may also indicate hematologic disorders like the myelodysplastic syndrome (MDS). MDS also requires anemia of course...
Since her blood tests are all normal, one test that may reveal some pathology is a brain scan. Various brain disorders may cause sleepiness like hematomas, tumors, etc. Make sure she's done the following tests though: urea, calcium, sodium, ESR, urinalysis. The tests you've mentioned (if they also include the aforementioned tests) are enough as a first check-up for sleepiness. Also make sure that you check her temperature (morning and evening) for at least three days. Sometimes an old individual may be suffering from infections without an overt clinical presentation. Sleepiness and lack of energy might be the only presenting symptom.
If no diagnosis can be suspected after all the tests are done then I doubt that further diagnostic evaluation will help. Perhaps she's just become too frail due to her age...
I hope it helps!
Kind Regards!
