The MRI is very likely a waste of time and money. If the neuro did a basic neuro exam, he would know if you have any symptoms that suggest an MRI.

Did your blood work include D3, B-12, and folate ?

What are you doing to reduce stress and anxiety ?

Anxiety meds are not a crutch so you can continue with a stressful life. Most common anxiolytics are benzodiazepines. Benzos are known to cause memory dysfunction.

Why do you want an anxiety med ?

btw, Anxiety meds effect you the same whether you have anxiety or not. They are sedatives unless they are of the anti-depressant form like SSRI's, SNRI's, or Tri-cyclics. They do not get consumed by the symptoms they are treating.
