Do I have brain damage?

I was undiagnosed for a long time, maybe a year. I never got the "physical" symptoms,  anaemia, poor balance,  reduced sensation of touch or tingling feet. My symptoms were reduced to fatigue, difficulty thinking and depression. I started treatment some weeks ago, and the depression and fatigue have gone away, but I still feel bad in the cognitive side. Is this gonna get better or is a permanent thing? What I don't understand is how I could have brain damage but no other nerve damage. Isn't the brain what the body protects the most?

What was you diagnosed with 

Be patient, it takes a long time for the treatment to repair things. It took me about a year to really begin to feel things were getting better. Are you taking a good B complex vitamin tablet to keep everything in balance? Do you know if your levels of ferritin, folate and VitD are good too? 

I haven't fully recovered my cognitive function, but I had very bad physical symptoms. You didn't have these so much, so hopefully you will recover fully. 

Best wishes

Not sure about vitamin D, but the other things are fine. I'll take a look.

I pressed my doctor to make me a b12 exam. My levels were quite low.

good question!
