sneeze

Avatar m tn Is anyone aware of a neuro/muscular disease with one of the signs being the loss/lack of the sneeze reflex?
Avatar n tn Also some allergens only cause a mild irritation and their aerosols are not big enough for a sneeze reflex to be completed. The reflex gets initiated because the nasal receptors are tickled and send out the sensation however since the irritant is not big enough to sustain the reflex, the reflex is not completed. Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
Avatar n tn area with lots of closely packed structures which cause neurological deficits when damaged. Strokes in the lateral medulla can abolish the sneeze reflex but in association with other signs of stroke such as clumsiness, weakness or sensoru loss, or inability to swallow a reflex has both afferent (incoming to the nervous system)) and efferent (outgoing) components. An interuption can occur at any point, not necessarily in the brain, and block the final response.
Avatar n tn But the problem is that since many days, I get a sneezing sensation but the automatic sneeze reflex just does not come. The issue started when a sneeze came but it just did not follow through and after that I am just unable to sneeze. Its as if my brain wont allow a sneeze! I feel fine physically. I have no pains etc. Also, it seems a few people had this issue....can anyone help me out if they have gone through the same? As far as I can see, it seems like a mental issue now.
383536 tn?1225030613 It is especially bad in the morning, and when I cough or sneeze. DH laughs at me every time I cough or sneeze because I gag so much (it's nervous laughter, because he does NOT do vomit very well). I am 30w4d and thought I would not have to deal with this anymore after my 2nd trimester, but I didn't get that lucky. Good luck to you! I hope it goes away!!
Avatar n tn In 1997, I had a period of a month or more where I could not sneeze; I would have the urge to sneeze, build up to the sneeze, but it would not come out. Then, I went back to "normal" sneezing. Then several years later, I had the same thing again, for over a month, but again, went back to "normal" sneezing. Now, over two years since the last episode, I have been experiencing the same thing again, for around 6 weeks.
Avatar m tn I will sneeze every time, and if I need to egg the sneeze on, I will look right at the light until I sneeze. If I feel a sneeze coming on, I will either look at the sun or a bright light in a room. I rarely sneeze in a low light situation. My doctor thinks I am nuts, as does my opthamologist. However, my Mom did this (but not my Dad) and both of my daughters do it too. My Mom says that her Mom did it as well. It's very strong reflex and completely uncontrollable.
914415 tn?1243052654 One minute post hyperventilation, an intermittent feeling of drowsiness, and there were intermittent right central and bilateral occipital phase reversal noticed. Definite stage II sleep was not recorded. With photic stimulation, there is fairly frequent spike wave activity noticed. The majority of them are between the photic stimulation and those episodes also happen quite frequently right after the photic stimulation. There are no corresponding clinical events noticed.
Avatar m tn Hi all, This will sound extremely bizarre, but I would be grateful if anyone is able to shed some light on this very annoying thing that I am experiencing. It all started when I rubbed my eyes in my mirror 2 years ago, and then my eyes started stinging really badly, and I found I couldn't sneeze for about 2 weeks. For about 2 years now, I have been experiencing an inability to sneeze naturally. The sneeze builds up, but it never completes.
Avatar m tn When I sneeze, I start sneezing 12 time with 30 seconds intervals between each sneeze. Does anyone elase have this and is there a remedy?
787406 tn?1339203183 This waking and sleeping EEG was done in referential, bipolar and transverse monages using photic stimulation and hyperventilation as provocation measures. The posterior dominant rhythm is 10 Hz. Drowsiness is manifested by a dropout of the posterior dominant rhythm and presence of 4-7 per second activity over the frontcentral regions. Sharp waves are noted over the left temporal region. Photic stimulation produced no driving response.

9407801 tn?1403606948 when i sneeze i experience pain in my chest, shoulders which goes all the way to my palms. it lasts from a couple of seconds to minutes. sneezing is now a painfull experience. Its now about 6 months or so.
Avatar n tn I am 22 years old and my boyfriend recently discovered a soft spot on the back of my head...so I did some research, and for all of you who are worried here are some facts: A fontanelle (or fontanel) is an anatomical feature on an infant's skull. In cleidocranial dysostosis* the skull fontanelle may be enlarged, and may be slow to close or may never close.
Avatar f tn Does it do the same when someone runs a blunt object up the outside of your foot along the outside? Could it be a very strong Plantar reflex? http://en.wikipedia.

Avatar n tn Two of these three same nerves also send other branches to the throat and are involved in triggering the cough reflex, gag reflex, and to a lesser extent actual sneezing. So there is at least a small theoretical basis to support your observations.
Avatar f tn I had the same worries cux i actually had the flu. But u shoukd be ok just remeber to keep hydrated and try to get some rest. The saline sprays might help reduce some of the sneezing! Hope you feel better!
410903 tn?1209588402 Of note, there is the presence of brief generalized spike and slow wave activity at approximately 3 Hz, lasting 1-2 seconds. This was a maximal during photic stimulation and hyperventilation. Clinical manifestations were described. The patient apparently would not snswer during this episode. Abnormal EEG consistent with a primarily generalized convulsive disorder such as would be seen in absence seizures.
Avatar n tn I know that sometimes when some people feel the need to sneeze they look at a light and this triggers a sneeze. I, too, find this helps. What doen't help, however, is when I walk out of somewhere dark or shaded into somewhere bright, whereupon I break into a violent sneezing fit. These fits usually contain around 5-7 sneezes although my record is 9. This causes great helarity amongst my friends and often to passers by.
609540 tn?1257316841 When I wake and I start to sneeze,the whole day I will sneeze and my nose is very itchy and my eyes become red and watery.Sometimes I don't know why I sneeze, but sometimes when there is a dust I sneeze a lot, so thus this means that iam allergy with the dust?
