History of progressive fatigue for past 5 years, now so bad that I returned to my physician. I was treated for Depression with Wellbutrin (didn 't work) and SSRI and Adderal (didn't work either.) Acute episodes (about 1-2 X's per year) accompanied by extreme bad breath and incapacitating fatigue requiring bedrest for 2-3 days. Over the past 2 year there is an increase in fatigue and I am unable to perform dailly activities. Light headedness has become more freqent over past 2 years and becoming more acute now, usually every day. Have seen GP, Cardiologist and Neurologist in past 3-4 months. Diagnosis of possible stroke 2 years ago (sudden onset numbness left arm and hand and grasping function). Positive Babinski left foot. All labs are normal, other than +1 ketones in urine. Heart normal. Echo and CA++ Scan show 0% chance of cardiac event. MRI of head/neck shows 70% occlusion right internal carotid. SPEC scan normal. CT angiography show stenosis.
So, here's the question. Can the level of fatigue I am experiencing be due to the carotid stenosis and yet not show any brain dysfunction on the MRI, CT or SPEC scan?
