The indicators of a brain injury are not part of a normal blood test. S100b and Tua proteins are not tested except in research or other extreme situations.

B-12, folate, D3, magnesium and such can be indicated in a normal test if the test was broad enough. The normal for B-12 is 200 to 970 pcgs/mL. An injured brain needs about 1000 pcgs/mL of B-12. Folate should be above 20. D3 is also important.

Are you getting quiet rest? Your brain needs it to start to recover. The nausea may be a cause of your weight loss. As much as you are concerned about struggling to gain some weight back, please don't complain too much. Plenty of us would like to be able to lose a few pounds. LOL.

Thyroid testing might be worthwhile as it can relate to weight loss.

Treatment for the panic attacks is worthwhile. I use a beta-blocker for panic attacks. I only take it when I have an attack that I can not use quiet for recovery. I rarely have a problem any more. I have learned to avoid the triggers.

Please feel free to tell us about your struggles.

My best to you.
