Does anyone have non epileptic seizures? I have been diagnosed with PNES and vestibular migraines. I also have absence seizures. Ive had mri's ct scans, and eeg's. Everything is normal. I have olfactory hallucinations as well. This episode of smelling burnt exhaust fumes has lasted for a week now. I have other type smells too..all burnt. I dont understand the difference between a migraine aura and a seizure aura. I have so many of the same symptoms of each and I am so confused as to what my true disorder is.
