Brief Answer:
BPPV (benign positional proximal vertigo), is one possibility, needs evaluation.

Detailed Answer:

Hi,

I had gone through your question and understand your concerns that you are having brain fog. I would like to ask you few more details.


Is your dizziness continuous or episodic ?


As per your clinical details, it appears to be BPPV (episodic-peripheral vertigo) or due to variation in blood sugar.

I suggest you to consult ent surgeon, get detailed Ent examination, vestibular tests (to differentiate central from peripheral vertigo), blood tests (blood sugar, serum electrolytes), BP monitoring. If necessary CT brain (age related ischemia). Depending on the examination, treatment can be started.


Hope this answers your question, if you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.


Wishing you good health.

Dizziness is most of the time. Brain fog is more of the issue.

Brief Answer:
Brain Fog requires investigations.

Detailed Answer:

Hello again,

Thanks for considering my answer and for your follow up.

Continuous dizziness and fogginess denote some systemic abnormality, it has to be evaluated. Blood work and a CT scan of the brain are the absolute minimum to rule out any kind of organic issue.

Kindly do these investigations at the earliest and upload them so we can discuss the results and what to do next.


All the best.

Take care.
