Right sided hemiparesis



(Stroke on the left side of the brain)

After a stroke in the left hemisphere, the patient is paralyzed on the right side of the body and vice versa. Paralysis is not always the case.

The speech and language center is located in the right hemisphere in left-handers.


Hemiparesis and hemiplegia
Hemiparesis refers to one-sided ('hemi') weakness ('paresis') The words 'hemiparesis' and 'hemiplegia' are used next to each other in practice.
In fact,  'plegia' means complete paralysis and 'paresis' means partial paralysis;

On one side of the body both arm and leg and face can be affected. It may also be that only the arm is affected, or only the leg or facial muscles.
Hemiparesis affects roughly 80 percent of stroke survivors, causing weakness or the inability to move one side of the body. 


Symptoms after a stroke in the left


Remember: One person with a stroke in this hemisphere may have one or two of these symptoms, the other has multiple. Roughly speaking:

  • disorders, paralysis or sensory disturbances on the right side of the body
  • vision on the right side of both eyes may have decreased (hemianopia)
  • speech and language problems (aphasia)
  • problems with object recognition (agnosia)
  • problems with daily activities, routines which formerly went well (apraxia)
  • memory for verbal (spoken) things
  • decreased analytical skills
  • problems with chronology (in order of time, cause and effect)
  • reduced timing and speed skills
  • left and right confusion
  • difficulty in dealing with numbers, understanding numbers and money
  • slow
  • shows some insecure, anxious and withdrawn behavior
  • risk of depression
  • Chance of changing moods, easily overwhelmed by emotions


Scientists are still discovering more functions that were previously roughly attributed to the 'other' brain hemisphere. The brains work as a whole. The hemispheres are divided into lobes again.

The blue area is the Frontal lobe

The yellow area is the Parietal lobe

The green area is the Temporal lobe

The red area is the Occipital lobe
