Slow foot reflex: Suggests possible nerve compression in lumbar or sacral spine, which could result from bulging/ruptured disc, bone spur compressing spinal cord or nerve root, or spinal stenosis. Suggest seeing orthopedic or neurosurgeon for evaluation, tests (including mri), options for treatment. If u have foot drop or similar problems, do not delay. Sooner the treatment, less damage. ...Read more
Assists with feeding: The rooting reflex is a primitive reflex that is present at birth that helps your baby breastfeed. When your baby's cheek is stroked s/he will turn towards that side and open their mouth, searching for the object. This helps with breastfeeding. This reflex generally goes away around 4 months of age. ...Read moreSee 4 more doctor answers
Good nerves: Some people have naturally brisk reflexes. If brisk reflexes are present at an early age and equal on the two sides, usually nothing wrong. Pathologically brisk reflexes can occur: a. If nervous system is overstimulated (hyperthyroid, crack, fright etc) or if the reflex centers become disinhibited by brain or spinal cord disease, . ...Read more
What are some physiological (non-psychological) causes of exaggerated spinal reflexes (i.E. Exaggerated jerking/flinching in response to light touch)?
Startle vs DTR's: Your description of exaggerated jerking with light touch sounds like someone with very brisk "startle" reflex, as in post traumatic stress disorder. This is a physiological response to hypervigilance, as ptsd encompasses the whole person and his/her body. Hyperactive deep tendon reflexes (dtr's) can result from conditions like cerebral palsy, strokes, inflammatory diseases, and brain injury. ...Read more
Is repeated startle response (i.e "jumping") harmful after I've had a concussion? My job involves sudden, loud sounds that often provoke startling.
May provoke symptoms: Although probably not harmful, loud noises and repetitive brain stimuli such as bright lights, heavy technology use, prolonged reading can all make concussion symptoms worse and prolong recovery. If you have to work, consider ear plugs or headphones if possible to reduce the loud noises and startling.

A child has sudden random outbursts of aggression and giggling, punching, hitting, running, jumping on tables, and kicking objects while laughing. Why?
Eval: I don't know the answer to this. If he is showing this behavior in more than one setting (i.e., school, home) than evaluation by a child psychiatrist, child psychologist or developmental psychologist may be beneficial. ...Read more
Yes. Which Style?: Yes. Obviously, any martial art or fighting that involves contact with the head can lead to concussion, traumatic brain injury, etc. There may be some styles which may be safer, such as Tai Chi & Aikido. These arts rarely have percussive impact. It all depends upon how you train. ...Read moreSee 1 more doctor answer
Yes: Rsd or chronic regional pain syndrome is usually seen in the upper or lower extremities and usually involves a wider area than the knee itself. For instance, we may see it involving the calf, ankle and foot or hand wrist and forearm. I have heard of this diagnosis being made in a single joint like the knee but I have never seen it myself. ...Read moreSee 2 more doctor answers
Thigh weakness: straightening leg from a bent and weight-bearing position (climbing stairs, squats, etc) = leg reflexively feels like buckling. Ideas?

This : This sounds like a serious issue that should be evaluated in-person by a qualified physician! if your weakness was sudden, there are numerous possible causes, most importantly associated with your nervous system. It does not sound like you had a trauma, so muscle-or-tendon ruptures are unlikely. The most common reason for this problem is an acute disc herniation in the lumbar spine, that can occur without back pain or even any kind of bending/lifting injury. This causes nerve compression that gives patients typically radiating leg pain, numbness and weakness. The muscles that are associated with each lumbar spine level need to be tested individually during a good physical examination, and the distribution of your numbness should be traced. That can often lead to a pretty good diagnosis, even before imaging studies are done. You will probably need a set of standing lumbar x-rays and then possibly an MRI of your back to determine the real cause of the problem. There could be an inflammatory problem with onevof your nerves in the buttock or leg, although that is not as common as nerve root compression in the lower spine. Very rarely can individual nerve roots be affected with a disease inside of the cauda equina, the lower part of your nervous system inside of the lumbar spine, so that is unlikely. Even more rare would be a spinal cord problem higher up in the spine, or some kind of stroke inside of your brain, so that would not be the first thing your doctor will be looking for. Make sure you tell your physician as clear as you can when the problem started, where you feel weak, and where the numbness is (front, side, back of the lower leg?). Associated fever, chills, recent weight loss and problems with urination are important to convey to your doctor also. Do not wait too long to go see someone. Hopefully you can be treated with a course of anti-inflammatory medicines (similar to ibuprofen) and maybe physical therapy to see if things improve. Even with weakness, there is no good evidence for early surgery, as most patients -even if they were weak for a long time from nerve-root compression- eventually regain their strength just fine. Depending on the evaluation and possible MRI scan, do not let yourself get scared into surgery right away; try non-operative treatments first. If things do not improve, and there is indeed a significant amount of nerve compression in the lumbar spine, surgery might be the answer, and it is often very successful for this. Good luck! ...Read moreSee 1 more doctor answer
