Physiological Non-Epileptic Seizures

I have read that physiological non-epileptic seizures can be triggered by lack of oxygen to the brain, migraine, heart arrhythmia and brain wave slowing among other things. Apparently, if a person is hooked up to an EEG at the time of this type of seizure, no epileptiform pattern is seen on the readout. How can someone have a physiological seizure and not have it show up on EEG? Is it that when someone's body is not receiving adequate signals from the brain, the muscles shake? If so, why? I have low blood pressure, migraine, slow heart rate and brain wave slowing in the frontal-temporal region. I have focal motor seizure-like episodes without LOC that are triggered by flashing lights. I have read that strong signals traveling through the optic nerve can trigger seizures if these signals pass near enough to regions of the brain that are compromised by scarring or lack of blood flow. Does this make any sense? On EEG, I have had bi-frontotemporal spikes during hyperventilation but on another EEG, my leg shook without any spikes being recorded. I am scheduled to have a video EEG in January 2019 so I might get some answers then. In the meantime, I am trying to make sense of all of this. Any thoughts?

Psychogenic non-epileptic seizures (PNES) are events resembling an epileptic seizure, but without the characteristic electrical discharges associated with epilepsy. They are of psychological origin, and are one type of non-epileptic seizure mimics.physiological --- Anything physiological has to do with the body and its systems. You might notice that your physiological response to a scary movie includes your heart beating faster and your hands getting sweaty.Have you ever stood up really fast and had your head start spinning??? It is because the flow of blood to your brain did not get your blood get to your brain fast enough in that period of time. It happeans to many people and they can and do lose conciousness for periods of time. They do look like they had a seizure. So yes miss diagnoses are made. Which is also why Epitologists (neurologists that speialize in epilepsy) have been working with the PNES people so fewer miss diagnosse are made.Meaning the seizures you are talking about do not start in the brain.Epileptic seizures start with an electrical impulse hitting wrong in your brain. They start with an electrical impulse hitting wrong. That wrong hit causes a hain reaction which is the seizure itself.I have low blood pressure, migraine, slow heart rate <<<< no problem with that and a person can have mor then one ailment and have seizures.It is however the brain wave slowing in the frontal-temporal region. lack of oxygen to the brain ---- synscopeFocal motor seizures??? Just which seizures the list can be a focal seizure?? They changed the names of seizures and thyoes of epilepsy when neurologists started specializing back in the mid to late 1980's. I was diagnosed with Grand Mal. Petite Mal and Focal Motor Epilepsy back in the early 1960's. Grand Mal seizures are todays generalzed tonicclonic seizures, Petite Mal seizures are now Absence seizures. Focal motor seizures are seizures that start in one area of the brain and can look like absenece seizures. Or can be any of the partial seizures. They can generalize farther and beome like a grand mal seizure with the convulsing only the person in htem is concious.The seizures that can be cause by light changes (flashing lights ot even a computr screen change are in the occipital lobe. Considering the nurve is just a part of the lobe.Yes scar tissue can be a cause for ones seizures.Now if one is having a seizure like legs twitching during the EEG you need to understand that the EEG can only read to certain debpths of the brain and the activity could be happening deeper in the brain they the pickups will read.
