Hello,
As per the symptoms described by you, these can be caused by multiple factors. Although a brain scan seems mandatory to me, till then you need to get your blood sugar and blood pressure check up as well.
The symptoms of a headache, brain fog and
dizziness can be caused by fluctuation in either of these two conditions.
Apart from that, I will suggest you keep yourself hydrated well. For that take ample amounts of fluids.
As the symptoms can have multiple etiologies, you should get your complete blood investigations including a renal and hepatic workout.
Apart from that, get your visual acuity testing and
inner ear check-up as well that could be a possible cause for the symptoms.
No doubt that the medication is taken by you (
Citalopram) is having a known profile for causing dizziness, you can certainly get it changed for some other medication.
As the symptoms have too many different etiologies, hence the treatment is dependent on the relevant tests and their specific treatment.
Do get all the above-mentioned health checkups to come to a conclusion.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Maninder, General & Family Physician
