what actually causes brain fog?
 

after all these years and way too much of it I still don't know the cause. I tested my typing speed with and without brain fog and it was the same. I thought brain fog would affect it. looked online but could not find answers.

Apparently, your brain fog is not influencing your muscle memory. Different parts of the brain are involved in each task.

Mine seems to be caused by an increase in HR and BP... I wonder if it does not have to do with an increase in intracranial hypertension

Yes, I do feel a little out of it, but I can still do certain things fast. The key difference is that the experience is not as vivid and I almost feel like I am not in control.

I read that pulsatile tinnitus can be a symptom of intracranial hypertension but I do not have any of the other symptoms and have no desire for a spinal tap.
This may sound crazy but when my brain fog/irritation calms down, I can feel three stabbing spots on different areas of the head where the irritation seems to originate from.

Doesn't sound crazy.. same thing happens to me and gets worse with more pressure... the only thing so far that relieves pressure is alcohol and is cheaper than any med i have tried for sure.. .however, i have succumbed to the idea of a lumbar puncture... you may seriously want to consider especially if you have papledemia...

I am going to see that young neuro that I like and see what he has to say. if it's necessary I will get it.

I thought it was my brain injury that caused it, however I think nutrition and sleep are factors as well. I was diagnosed with sleep apnea and was advised to lose weight. A good night's sleep meant a world of difference for me, but changing my diet was also effective with helping my alertness. I cut out grains (mostly wheat) and began eating more fresh vegetables and fruit and lost over 20 pounds.

My understanding of vitamin therapy/rehab for brain injury is that it gives the injured brain a boost to help it work more efficiently. I believe that the fruit and veggies helps with that as well, and in fact my whole body is improved since changing my diet.

To summarize, the vitamin super charge combined with a diet change and good sleep has helped TREMENDOUSLY. I am working in a daily exercise routine as well which should add to the benefits along with meditation.

Vitamin regimen, a healthy diet, exercise and sleep.

I think that determining the cause is certainly useful, and helpful, but I'm good with whatever works. The bottom line is that the fog has gone because I'm getting a better quality sleep, have a greatly improved diet and the vitamin boost is great. My new body is a bonus!

Lack of good sleep will make anyone have brain fog.
The nights I have little sleep are a predictor for days of bad vertigo.
Go figure.
