It seems unlikely that a physician would write “head is getting older” in an MRI or CT scan report. Next time, simply report the result exactly as it was written. You also didn’t explain that state of “coma” very well. Coma that is due to stress and anxiety is not a real coma.

Blood vessels on the neck can become narrowed due to atherosclerosis. The walls of an artery are damaged because of the cholesterol precipitation. Atherosclerotic plaques form in the artery’s wall and they are places susceptible for developing thrombi. A thrombus created on such plaque can separate from the plague and tcan reach the brain causing temporary ischemia (thromboembolia) through the blood flow . Such ischemias are usually temporary because there are blood mechanisms that the body triggers that dissolve the thrombus (fibrinolisis).

The symptoms of an ischemia are the same as in blood insult, but last only temporarily. After dissolving the thrombus ,the blood flow is established again and the symptoms disappear. Your state of “coma” could be due to such a transitory ischemic attack. You can request a carotid arteriography to reveal the atherosclerotic plaques or to check to see if there are any.
