How can i be sure that i don t have brain damage from carbon monoxide poisoning ?

Symptoms: Unclear what occurred but if sufficient exposure, chronically, you would at least have headaches. Acute severe exposure might cause memory loss, incoordination, imbalance, and/or tremors like parkinson's. If you lack the above, do not worry, as you have escaped unscathed.

Consult your doctor: I would recommend discussing this with your doctor or a neurologist. Carbon monoxide poisoning may cause damage to specific areas in the brain and may be diagnosed with a head ct or preferably a brain mri. A radiologic study, however, does not replace appropriate medical consultation and evaluation.
