This is an issue that deserves attention, as research examining iron levels in Americans shows that more people have iron levels that are considered too high, than levels that are deficient. In one study of more than 1,000 people, only 3 percent were iron deficient, but 13 percent had iron overload. 1. What are the Health Risks of Too Much Iron?
Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is, accompanied by spasticity (another form of hyperexcitability).
When your muscles contract, become stiff, or spasm involuntarily, it is called spasticity. Spasticity can make it difficult to walk, move, or talk. It can be uncomfortable and painful at times. Spasticity occurs when the nerve impulses that control muscle movement are interrupted or damaged. A variety of conditions can cause this, including spinal cord injury, brain injury, and diseases such as amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS).
