Hyperreflexia : Hyperreflexia means abnormally brisk (or "jumpy") reflexes. Clonus, most often seen at the ankles, is an example of hyperreflexia. Hemiparesis is weakness on one side of the body. As you can see, these three words are not really "diagnoses", instead, they are descriptions of physical examination findings. These findings are usually caused by a problem affecting a population of what is called "upper motor neurons". Upper motor neurons live in the cerebral cortex, and have many functions including voluntary movement of the opposite side of the body. Upper motor neuron problems can be caused at or before birth (such as cerebral palsy), or can be caused by problems that develop later (these include strokes, inflammatory diseases, and the effects of injuries acquired in accidents or during strokes). Problems in the lumbar (or low back) part of the spine is hardly ever the source of upper motor neuron problems because there are no upper motor neurons in the lumbar spine (except possibly in very young children). It is more likely for those sorts of problems to be found in the brain or in the cervical spine (neck). Mri scans are sort of like televisions. They have to be tuned to show what you are interested in seeing. For example, if an MRI is not tuned to look at acute inflammation, it won't find it.

Cerebral palsy: Children can be missed for this diagnosis, especially if its very mild. Not sure if your child had a long or laborous delivery when you had him, but this can deprive the brain of oxygen during the delivery. Many times children recover well afterwards and cerebral palsy is ruled out. It then manifests later in life as the clonus hyperreflexia or an achilles tendon rupture. See a pm;r/neuro doc.
