Based on your symptoms of dizziness
, confusion, large pupils, unable to get words out,(dysathria), slight weakness on the left side of the body with intense headache
One need to consider two conditions, either a structural lesion in brain (stroke
, tumor), or other possibility is meningitis (inflammation of brain covering) which can also produce same symptoms.
Since MRI brain does not show lesion, You require lumbar puncture
and CSF study to arrive at a diagnosis (to rule out chronic meningitis
Meantime you need to have antiplatelets also (as 30% cases MRI can be normal)
It might be worthwhile to consult neurologist
and plan the aforementioned tests.
