Possible causes for bilateral ankle clonus if spine and brain MRI are normal? Clonus is more prominent on the left side. Can clonus ever be bening?
I have bilateral ankle clonus. Spine MRI was normal. Seeing a neurologist soon. Could MS-disease cause this by affeting the brain instead of spine?
Clonus: Clonus is a sign that suggests the pathway that regulates muscle contraction was disrupted at some time. It is possible that changes in the brain, not the spine, caused this.

Developed nonsustained ankle clonus unilateral. 2 years ago had a neuro exam and this was not present. Is developing it a bad sign?
Sometimes it means something. Non sustained clonus sometimes does not hold up from exam to exam- some people are not good at detecting this.

I heard that immature myelin in toddlers can cause mild ankle clonus, is it true? When does the myelin will get mature?
Maturation: The nervous system matures from top down and inside to outside. Ankle clonus is normal in infants until they begin to walk, which the maturation allows. Persistence after 15-18 mo would be a problem. They first gain a wide grasp with fingers like pincers, but fine motor control of the individual fingers will not come in until well into school age. ...Read more
