My son is ten and does the same exact thing and he has done it since a baby. I thought he would outgrow it however it seems so happen more often now that he is older and I do notice it a lot more. I have not taken him to see a doctor about the situation lately and all his visits have always shown normal results. He does well in school and sports It seem random and mostly when he gets excited.
When I was 25 years old I suffered from depression and I visited a phycologist to find the root cause of my anxieties. It was then that I opened up about this 'tensing habit'.
I've experienced much of the same symptoms everyone is describing here.. If I'm alone and something I see or think about causes excitement I go into 'hulk mode' like I'm about to evolve into a different Pokemon. I scrunch up my face, usually bringing my hands up to around my mouth and experience a huge influx of adrenaline even only for a few short seconds.. at which point I usually notice my previously subconscious actions and stop.
I think the adrenaline and relief that this momentarily brings me from any excitement or anxieties I suffer from are what feeds this habit into something I cannot stop doing.
@Scrynthe, I finally made my concerns about this public when I was 25 as I also noticed that I began to experience headaches (or like a constant pressure) in my left temple and doctors we're concerned that it was possibly a tumor so I had an MRI scan but results showed a healthy functioning brain. The Doctors could not relate the characteristics of my habits to anything except tourette's and autism, both of which they would not diagnose me for and of which I know I do not have.
A few years ago I was convinced that it was ADHD but I do not share many of the symptoms associated with that disorder either. So quite possibly it is 'this primary motor (repetitive) stereotypy' that Dr John Hopkins describes.
I am 28 now and still experience these fits when I am alone. It still allows me to lead a relatively normal life except I do believe this habit affects my focus, attentiveness and motivation because if something provokes me to 'have an episode', often the adrenaline following that throws me off track and I can never regain focus.
Curious to hear more about diet and whether that can effect the urge. Some adult's here seem happy to live with it but I for one would love to hear of a cure?
Hi, look up complex motor stereotypy. A dr at Johns Hopkins specialize in it. I just discovered it for my son. my 9 month old has been making the O; face as well as other facial movements and stiffening his legs and waving his arms when excited. There are a couple Facebook groups and there are some adults on there that say they have always had it and they just learned to control it as they got older.
I'm glad so many people seem to experience the same thing. Just because it makes me feel more "normal." Haha. But seriously I do not think it is anything to worry about. I have been doing this shaking, huming, and grimacing or contorting my face when excited since I was a kid and I still do it sometimes. I am 32. Sorry I think some kids may not out grow this as I did not and neither did my 34 year old sister. I don't think it hinders me in any real way though. I am fully concious doing this and I only do it when I'm alone. I think it may be related to stress, diet, and a neurological influence. I was socially awkward as a kid but I grew out of that and am very friendly now. The same with my sister. I am able to work, socialize, travel, drive, and do everything a healthy adult can do. I hope this helps for people who may be experiencing this or with their children. I have noticed that I do it a lot less when I am eating really healthy, which I did not as much as a child.
Clearing Sailing above seems to have the right answer. My son did the open mouth/ hand twitching and stiff back routine at times when he was only 3 months old up until he was about 5 or so. I had an EEG done on him when he was 2 to rule out seizures. He did end up getting diagnosed with ADHD and used Ritalin during school hours once he turned 10 -- which helped tremendously in school. I think he just learned to control it. I tend to have feelings of a rush of adrenaline myself at times for no apparent reason. My son is 35 and I am 59 and we both are having successful lives! Never hurts to get all things checked out and answers given by professional doctors. But try not to make a big deal out of it -- to make them feel bad. I just would ask my son to do something active (engage in folding towels or something similar) when he did his "act." Perhaps this helped him recognize how to control what I feel is a "burst of energy". God wires us all differently and we just learn how to process our environment. (My son tended to do this when he was very tired. He was never a person that yawned. It was like he did this instead of yawning.)
My daughter is 5 and has done "the excited shaking" since she was a baby. She is also a toe walker. It has been brought to my attention recently that all of these things probably stem from sensory disorder. I took her to a neurologist last week and he did order and MRI for her. This will take place in Nov. He doesn't seem overly concerned. He just wants to rule some things out.
