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).
spasticity. [spastisâ²itÄ]. Etymology: Gk, spastikos, drawing in. a form of muscular hypertonicity with increased resistance to stretch. It usually involves the flexors of the arms and the extensors of the legs.The hypertonicity is often associated with weakness, increased deep reflexes, and diminished superficial reflexes. Moderate spasticity is characterized by movements that require great effort and lack of normal coordination.Slight spasticity may be marked by gross movements that are coordinated smoothly but combine selective movement patterns that are incoordinated or impossible.ne type of increase in muscle tone at rest; characterized by increased resistance to passive stretch, velocity dependent and asymmetric about joints (that is, greater in the flexor muscles at the elbow and the extensor muscles at the knee).
