What is Hemiparesis (Weakness of One Side of the Body)?

Hemiparesis is defined as partial weakness of the arm and leg on one side of the body (right or left). It covers a wide spectrum from complete paralysis (hemiplegia) to mild weakness. It usually heralds an event affecting one of the cerebral hemispheres or the nerve pathways serving it.

While the most common cause is stroke, brain tumors, head trauma, multiple sclerosis, encephalitis, and brain abscesses can also cause hemiparesis. In children, cerebral palsy is among the common causes of hemiparesis.

An early-stage neurological evaluation, imaging, and laboratory tests are used to investigate the underlying cause. Treatment success is directly related to the underlying cause, prompt intervention, and ongoing rehabilitation.

Symptoms

Weakness in the arm and leg on one side of the body
Drooping or asymmetry of the face on the same side

Coordination problems on the affected side

Risk Factors

Hypertension, diabetes, and high cholesterol
Prior history of stroke or transient ischemic attack

  • Sudden-onset weakness or facial asymmetry (urgent — suspected stroke)
  • If accompanied by speech disturbance and altered consciousness
  • If weakness progresses over hours
