Diagnosis
Identifying hemiparesis can be challenging, as many cases are congenital and go unnoticed during birth. It is often not until later in infancy when parents observe weakness on one side of the child’s body that concerns arise. To diagnose hemiparesis, a doctor will perform a thorough physical examination, which may involve testing reflexes, sensation, and strength. Advanced imaging techniques like MRIs and CT scans are also used to pinpoint the underlying cause and determine the specific areas of the brain that have been affected.
Range of Effects
Hemiparesis can vary in its impact, with some individuals experiencing mild effects while others are severely disabled. The extent of weakness can also differ, with some individuals having more control over their movements and others having limited control. Most individuals with hemiparesis exhibit partial paralysis or weakness on one side of their body. When the weakness occurs on the opposite side of the body as the damaged brain hemisphere, it is referred to as contralateral weakness. On the other hand, when the weakness occurs on the same side of the body, it is referred to as ipsilateral weakness. The latter is more common in cases where the damage is located in the spinal cord or brain stem.
