Hi, thanks for the question and I am very glad to help you with your health concerns. I had posted my answer at your previous question too and I am not sure whether you have received that answer or not, and I will post below here the exact copy of my answer which I had posted earlier at your other question.
This is the exact copy of my answer at your previous question;
“If she is having tongue bite then this looks like a seizure more than a syncope. I am not sure whether she had a Routine EEG (study of the brain waves) done or not. If not done she needs a Routine EEG asap because Routine EEG can help in telling us whether these episodes are seizures or not. If she already had a Routine EEG then she would require a Prolonged monitoring EEG like Ambulatory EEG for 72 hours etc which can help in establishing the correct diagnosis.
Serious possibilities like brain tumors etc are unlikely because she had a normal CAT scan of the brain. However because the CAT scan has come normal she now needs an MRI scan of the brain. MRI scan can identify conditions which might have been missed by a CAT scan so an MRI scan of the brain is recommended along with the EEG. However please not to worry about serious possibilities or life threatening conditions like brain tumors etc because such serious possibilities can be diagnosed with the CAT scan itself and her CAT scan being normal such serious possibilities appear unlikely. She will also need a test called as Tilt Table Test to explore the possibility of Syncope. If the syncope diagnosis is confirmed then the neurologist has to consider starting her on syncope treatments which may include trying her on meds like SSRI agents or Beta Blockers etc. If the seizure diagnosis is confirmed then the neurologist has to consider starting her on seizure meds to prevent these type of episodes happening in the future.”
In this question you have inquired about the possible role of environmental stimuli for her episodes, and the answer is yes, environmental stimuli can play a role. In fact seizures or syncope - both can get triggered due to environment. First she needs the additional investigations like EEG, MRI scan of the brain, and a Tilt table test etc to arrive at a correct diagnosis – Seizure disorder (Epilepsy) Versus Syncope and then she needs to be treated appropriately as discussed earlier above.
