This is a normal symptom as it is affecting parts of the nervous system.
In addition to @_OM’s excellent suggestions (all on point), please add:
Blood Brain Barrier Repair to protect the endothelial junctions, which are disrupted in this case.

For the nervous system, which disrupts and affects the rest of the system downstream, one can also see how one responds to the protective Brain and Spine Antioxidant Complex.
One can also use Plasma Brain of Youth or Brain Regeneration.
