Body jerking could be restless leg syndrome. Did this show up after you were put on med for anxiety (possible side effect)?

Brain fog can come from lack of adequate sleep, which could be due to restless leg syndrome.

Try eliminating caffeine, drinking a large glass of orange juice every day, and supplementing with folic acid (folate) b6 b12 and magnesium may be helpful.

Good luck and God bless!

Do not automatically assume you need to take anxiety pills... They will only lead to more problems in the long run.

Try some dietary changes and take some supplements.

Best of luck

The hardest thing to do when you feel so crummy, is to research your problems, however, only you know what your feeling and what is normal for you. I would encourage you to do some research on the topics below. In your case I believe it is a good idea to go to the neurologist and proceed with the MRI. I would continue to take the medication for anxiety until you see a specialist. I would still do research between now and then, and don't give up hope if the results are normal. I would also recommend seeing an MD that specializes in FMS/CFS/MS/Lupus, or a Reumatologist.

Research:

FMS - Fibromyalgia
CFS - Chronic Fatigue
MS - Multiple Sclerosis
Lupus
Restless Leg Syndrome

Reviewing these may lead to looking into other conditions as well. Many sites with have questionaires that will help identify your symptoms. I hope this helps, please feel free to write if you have more questions.

I had the brain fog you describe for about one year. I would have conversations with people and forget what we had just talked about 5 minutes later. I went through my chain of doctors with no explanation of what was wrong with me. If you want to get rid of this mind fog take olive leaf extract. You can find it at any health nutrition store. Get some with a high % of oleuropein. I have to take four a day otherwise I the brain fog comes back along with the weird dull constant headaches and the marked fatigue during the middle of the day. I really hope this helps because I know exactly how you feel right now. God Bless

Like all of you I have had brain fog for ages. Please check out if you have diabetes and are on a sugar high. Also check out your liver as this can be a symptom of liver disease.
