Brief Answer: Condition warrants further observation Detailed Answer: Hi, Thanks for writing to us, From the history you have provided, it seems like you have experienced a neurological event that could have had several causes. It may have been a partial seizure involving the occipital or parietal lobe of the brain. Having a normal EEG does not rule out the possibility of a seizure. There are several drawbacks in EEG, they only record the electrical activity in the outer part of the brain, it requires a synchronous activation to show up and the test is usually done when the patient is not having an active attack (as in your case) so it may be normal the first time. Since you experienced the phenomenon while falling asleep, a sleep EEG may be useful to gather some more information. Moreover, if at all it was an actual seizure, only one attack of seizure does not mean one has epilepsy. And nor is treatment recommended at this point. It could have been a side effect of one of the drugs you are on. Drugs can be seizurogenic (can cause seizures) in some individuals. It is very difficult to pin-point and say which drug has caused it, but you may consult your physician regarding this. It could have happened due to several other causes, like hypoglycemia, stress, sleep deprivation, uncontrolled hypertension etc. In this case, if the cause does not recur, the attack is unlikely to occur again. It could also have been a completely benign phenomenon called as the hypnogogic hallucinations that tends to occur in normal individuals while falling asleep. Usually one has a sensation of sinking or falling from a height. This is completely normal and warrants no treatment. Hope this helps, Dr A Rao

Brief Answer: MRI neck, vertebral and carotid Doppler Detailed Answer: Hi, Thanks for writing back, You had not mentioned this complain in your previous query. If you have a pathological disc in C6 and C7 and are experiencing stiffness and intermittent confusion on bending neck with an odd feeling, you may require investigating it with MRI neck, vertebral and carotid Doppler to rule out a compromised blood circulation to the posterior part of the brain from vertebrae. A compromised blood circulation to that part of the brain could lead to these symptoms. Visit a neurologist for a detailed evaluation at the earliest. I hope this helps, Dr. A Rao Kavoor
