My PhD adviser and I have had that debate a number of times. For the congenital case, we can't say one way or the other. But in the acute case, where there are localized lesions to the parts of the cerebellum thought to be involved in cognition, the effect seems to be primarily cognitive. From anatomical studies, we also know that there are "loops" formed between non-motor areas of the cerebral cortex and the cerebellum.
- TheLoneWolfling 12y agoBut couldn't that alternatively be explained by the cerebral cortex being able to act as a "backup" of sorts for the cerebellum, to the extent of "neglecting" its ordinary tasks? It would make sense if the brain were to "consider" motor control to be at a higher priority than cognition, and was designed as such. (Sort of like in a pinch a kitchen might use a cook as a dishwasher.) I'm using wishy-washy words here, sorry. I don't know how better to explain it.
- blennon 12y agoIt's unclear whether the circuitry of the cerebral cortex has the ability to implement the function of the cerebellum (whatever that may be, which we don't really understand). I think we're a long ways off from answering that question.
- TheLoneWolfling 12y agoWell, given this development, I think it's fair to say there's something else that can implement the function of the cerebellum.
- blennon 12y agoSomething that can partially implement the function of the cerebellum.
- TheLoneWolfling 12y agoTrue.
- cmdrfred 12y agoIt might be sort of like switching from hardware rendering of video to software rendering.
- celticninja 12y agoIs there a way to check for this other than brain scans? My son is incredibly clumsy at 2.5years old and he fell off the bed when he was younger, perhaps 1 year old, and had a nasty bang to his fore head. He is a twin and his sister doesn't have as many falls as he does.
- danudey 12y agoSomething tells me that going to your family doctor and saying 'I'm concerned that my son is missing some of his brain' isn't going to get you a referral to radiology, but who knows. If he hit his forehead really hard I'd probably take him in in case of a concussion, and that would probably tell you in some detail.
- celticninja 12y agoI did take him at the time and they said he was fine but he was also so small he wasn't really coordinated or talking anyway.
- x0054 12y agoBoys will be boys. I fell out of my bed at the age of 8! As far as I can tell, I am perfectly normal with excellent sense of balance now at the age of 30. As long as your son eats well, sleeps well, and is otherwise healthy, give it a few more years before you really start to worry.
- eru 12y agoAlso, make sure to encourage movement (adults call it exercise, for kids is play). I used to be really clumsy as a kid before I got into sports as a late teenager.
- mmakunas 12y agoConsider occupational therapy as well. It was very very helpful for my daughter, who was "behind the curve" with her gross motor skills. It's not just about increasing physical ability, either. Lack of core strength can affect the ability to sit still and focus as the body gets fatigued more easily.
