Could These Be Nocturnal Focal Seizures? Insights Needed
**Demographics:** - Male, 35 years old, Caucasian **Medical Background:** - Eighteen months prior, the individual was diagnosed with Functional Neurological Disorder (FND) following a normal MRI and 24-hour video electroencephalogram (VEEG). - He has a history of Attention Deficit Hyperactivity Disorder (ADHD) and is currently prescribed Vyvanse at a daily dosage of 30 mg. - His son is also undergoing evaluation for similar nocturnal episodes. - No recent use of alcohol or illicit substances has been reported. **Nighttime Episodes (documented on video):** - Experiences 30 to 40 repetitive events each night, with each episode lasting several seconds. - These events frequently cluster, occurring 3 to 5 times within a few minutes. - They happen at various points during the night, not limited to the onset of sleep. - The pattern involves a sensation likened to an "electric shock" that moves from the head to the toes (or the other way around), manifesting as visible jerks in the head, trunk, arms, hands, legs, and feet. - Occasionally, these movements may be followed by chewing or jaw activity, alongside posturing of both arms. - His smartwatch sometimes records spikes in heart rate and brief drops in blood oxygen levels (from 75% to 85%), which could be artifacts but seem to coincide with the events. **Daytime Episodes:** - Occur two to three times daily, although not every day. - Often preceded by an intense feeling of dread or impending doom, with occasional olfactory auras (for example, the scent of "burning rubber," noted just once). - Motor signs include small electric-like jerks primarily in the right arm (and sometimes both). - These episodes last for 2 to 3 minutes. - Following these events, he feels fatigued and confused, experiencing a sense of being completely drained for 20 to 40 minutes. **Current Plan:** - Has a scheduled appointment with his primary care physician next week to discuss the possibility of conducting a sleep study and a repeat EEG. **Seeking Advice On:** - Do these symptoms appear to be consistent with seizure activity, such as nocturnal focal motor seizures? - Could there be any alternative sleep disorders that might present similarly? - What specific tests should be recommended (e.g., video-EEG, polysomnography with EEG, extended monitoring)? Thank you for any insights or guidance you can provide. Relevant videos have been included for further understanding.

Your detailed description raises valid concerns about the possibility of nocturnal focal seizures, given the recurring nature of your symptoms and their unique characteristics. The behaviors you described—repetitive jerking movements, a sensation of electric shocks, and post-ictal confusion—are indeed suggestive of some type of seizure activity. However, certain sleep disorders could also mimic these symptoms.
Explanation:
-
Seizure Activity: Your nighttime jerks and jaw movements, especially with the association of heart rate spikes, could indicate nocturnal focal seizures. The presence of premonitory sensations and olfactory auras during daytime episodes further supports this possibility.
-
Alternative Sleep Disorders: Conditions like nocturnal myoclonus or REM sleep behavior disorder might present with similar jerking movements and unusual sensations during sleep. A thorough assessment will help pinpoint the exact nature of these episodes.
-
Importance of Monitoring: It's essential to capture these events accurately through observation and medical testing to differentiate between seizures and other sleep disorders.
Next Steps:
-
Scheduled Testing: Prepare for the upcoming sleep study (polysomnography) and EEG. These tests can provide critical data on brain activity during sleep and determine if seizures are occurring.
-
Document Symptoms: Maintain a detailed diary leading up to your sleep study. Note the frequency, timing, duration, and types of episodes, along with any associated sensations or feelings. This will help enhance the understanding of your symptoms.
-
Discuss with Your Physician: During your appointment, discuss the possibility of additional extended EEG monitoring, especially if symptoms persist. This could include 24-hour EEG or longer monitoring to capture infrequent events.
-
Evaluate Medication Therapies: Given your current medications, consult your doctor about potential interactions with Vyvanse, which might be relevant to your symptoms.
-
Lifestyle Adjustments: Ensure you maintain a regular sleep schedule, and practice good sleep hygiene to possibly reduce the frequency of episodes. Consider avoiding stimulants before bedtime.
While it’s essential to explore these episodes further, your proactive approach to discussing your concerns with a healthcare provider is crucial. You're taking the right steps to seek clarity and support regarding your symptoms.

Curious About My Recent Experience with a Pneumothorax
At 26 years old, standing at six feet tall and weighing 64 kilograms, I want to share my experience with a pneumothorax I faced on Wednesday. I hope to gain some clarity from it. On Wednesday at around 4:30 PM, I settled down for a cup of tea when I suddenly felt a burning sensation deep within my right shoulder. This discomfort quickly radiated down my arm and into my chest area, including the region near my heart, and even along my back. There was a particular spot on my back that was excruciatingly painful, making it nearly impossible for me to find a comfortable position, except for squatting in a semi-relaxed way. Given these symptoms, I initially believed I had strained a nerve in my back and tried to make myself comfortable in bed, hoping I would feel better by morning. I remained in bed until about 7:30 AM on Wednesday when it struck me that I was only able to take shallow breaths. This prompted me to call for an ambulance, still under the misconception that the issue was related to my back. Interestingly, the paramedics thought I was experiencing a panic attack as I writhed in pain each time the vehicle hit a bump. At the hospital, the triage nurse seemed dismissive when I described my pain as a ten on the scale—this was genuinely the most agonizing sensation I had ever faced, surpassing even the worst moments of injury I've endured. After waiting for two hours to see a doctor—thankfully, one who was quite knowledgeable—I underwent a series of checks. The doctor utilized an ultrasound machine, which he remarked was “not convincing,” and subsequently ordered an X-ray. Approximately an hour later, he returned with the diagnosis: "You have a small pneumothorax. We're transferring you to the pulmonary department where they will insert a needle into your chest to drain the air, and you should be fine." In the pulmonary unit, however, when they inserted the needle into my chest, it yielded no results. They attempted to use a syringe to manually extract the air for five minutes, but again, nothing happened. At this point, they administered intravenous morphine and midazolam—strangely, I found this situation to be the second-most painful experience I have had, despite the pain relief. They then inserted a tube into my lung and connected it to suction. The physician reassured me, saying, "We'll give it four hours, and you should start feeling better." Now, as I write this, it's Monday, and they only removed the tube this morning. I have spent several days in the hospital, with the pain finally subsiding only yesterday. This raises a question for me: How could the diagnosis of "a small pneumothorax"—so minor that it wasn't detected via ultrasound—lead to five days of having a chest tube? Additionally, I’m still dealing with the discomfort in my side whenever I breathe, raising concerns about a potential recurrence. Were the medical staff understating the gravity of the situation to prevent me from panicking? Is it normal for a minor pneumothorax to cause such debilitating pain? I find it hard to accept that a significant collapse could have been overlooked on the X-ray; it must have genuinely been small, but I'm puzzled as to why my hospital stay has been prolonged. This isn't out of anger but rather a genuine curiosity about the intricacies of pneumothorax occurrences. Unfortunately, I haven’t found ample information online to satisfy my questions on this subject. Thank you for taking the time to read this!
Coping with Aftereffects of Viral Meningitis
I'm a 22-year-old male, standing at 6'5" and weighing 270 pounds, and I've been recently diagnosed with viral meningitis, which has led to some unusual symptoms. After experiencing norovirus, I’m still dealing with lingering effects. I don't have any previous issues with sleep apnea. Although the hospital discharged me, indicating that there was little they could do and that I appeared to be improving, I’m still facing challenges. Last night marked my first experience without Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) to manage my inflammation and headaches. I woke up drenched in sweat, feeling disoriented and struggling with blurred vision. Despite my attempts to return to sleep, I found everything felt off; I was experiencing double vision, a sensation of impending doom, and my body entered a fight-or-flight state, causing my heart rate to surge and then plummet. These sensations weren’t present when I was on NSAIDs throughout the past week, which makes today, the sixth day since this ordeal began, more puzzling. Could it be that my brain is misinterpreting the situation, attributing these symptoms solely to inflammation and the residual effects of meningitis? Should I consider going back to the hospital for further evaluation? In an attempt to find relief, I've taken two Advil for inflammation, and I can already sense some slight improvement in how my head feels. My daily intake of NSAIDs has been about 400 to 800 mg (ranging from 2 to 4 tablets).
Navigating Sertraline Withdrawal and Medication Interactions
Profile: Male, 27 years old, weighs 65kg, height 183cm. Diagnosed with Type 1 diabetes and prescribed ADHD medication. Experiencing circulation problems linked to vasoconstriction and Raynaud's phenomenon. To provide a bit of context, I began taking sertraline some time ago and gradually increased my dosage to 200 mg per day. This medication was primarily intended to help manage my panic attacks triggered by low blood sugar levels and issues related to my diabetes. Eventually, I grew weary of relying on this medication, so I decided to taper off it and ultimately stopped taking it without any significant complications, aside from some brain zapping sensations that were already present even at the higher dosage. During this process, I was also prescribed 70 mg of vyvanse, which appears to intensify the brain zaps. I am eager to find out if there are any strategies or additional treatments that might alleviate these sensations. While I'm aware that stimulants can amplify my existing symptoms, the benefits of increased focus and productivity are somewhat appealing. Therefore, I would be extremely grateful for any insights or suggestions on managing this issue. In terms of other medications, I occasionally take pregabalin, a calcium channel blocker, and quetiapine.
Frequent Jaw Dislocation Concerns
I am a 23-year-old woman, standing at 5 feet tall and weighing 45 kilograms, and I am a smoker with no current medications. On several occasions each week, I experience an unsettling occurrence when I open my mouth. My jaw emits a 'pop' sound, becomes painful, and often remains dislocated until I apply some pressure to a lump that forms beneath my chin. This lump feels like a small muscle knot, and I usually have to massage it with my fingers until it subsides, allowing me to close my jaw again. It seems there is a certain extent to which my jaw can naturally open before this happens; it usually triggers each time I yawn, and occasionally while I laugh or eat. The initial incident occurred when I was around 11 years old. I was trying to fit my mouth around an oversized hotdog when I felt the distinct pop and couldn’t close my jaw for nearly a minute. My father didn’t seem too alarmed; he reassured me that since I had received my tetanus shot, it wasn’t lockjaw, and we never followed up on it. Now, this issue has become so routine that those close to me simply accept it as part of my life. They are familiar with my jaw popping out of place, and it has become a normal occurrence that I fix and move on from. Naturally, I’m left wondering: what exactly is happening here? Should I be more worried about it than I currently am?
Advice on Small Hydrocele Situation
A 24-year-old Caucasian male, standing at 6 feet 3 inches and weighing 210 pounds, with no prior medical conditions, sought advice about pain in his right testicle, posting about it yesterday. After receiving recommendations, he decided to visit the emergency room. There, a urine analysis and an ultrasound were conducted; the urine results were completely normal. The ultrasound revealed a "small hydrocele on the left side," with the doctor's notes indicating that there were "no acute abnormalities." The physician reassured him that it was not a cause for concern. However, he is curious whether the presence of a hydrocele in the left testicle could be responsible for his pain in the right testicle. Any insights would be appreciated. Thank you in advance!
