stroke: perception changes

overview

when a stroke occurs on the right side of the brain, a person's ability to judge distance, size, position, rate of movement, form, and the way parts relate to the whole is affected (spatial-perceptual problems). people with these problems may have more trouble learning to care for themselves.

signs of perception problems are often noticed by the caregiver of a person who has had a stroke. these signs may include:

• not noticing people or things on the affected side and turning their head or eyes to the unaffected side. the person may not be able to steer a wheelchair through a large doorway without bumping the door frame.
• not being aware of body parts on the affected side.
• having trouble recalling how to form numbers and letters, or confusing similar numbers. the person may not be able to add numbers.
• having trouble recalling the written spelling of words. the person may not be able to read.
• confusing the inside and outside of clothing or the right and left sides of clothing.
• having a hard time knowing when they're sitting or standing.

helping someone who has perception changes

if a person has perception problems after a stroke, the stroke rehab team can teach you how to help. here are some examples.

• help prevent a fall.
  • cut down on clutter.
  • make sure that rooms are well lit.
  • install night lights in the bedroom and bathroom.
• avoid rapid movements around the person.

  other people moving around in the room also may be distracting.

• mark lines on door frames or full-length mirrors.

  this can help the person see what is vertical.

• do not overestimate the person's abilities.

  watch to see what can be done safely rather than taking the person's word for it.

• help the person do a task.
  • tell the person how to do things if they have trouble remembering how to do a task.
  • put your hands in your pockets to keep yourself from gesturing as you talk the person through the steps.
  • it may also be good to have the person talk through the task.
  • give lots of praise.
• break tasks into small steps.
  • encourage the person to slow down and check each step carefully.
  • don't nag. nagging may cause the person to become angry and upset.
• arrange transportation.

  people with perception problems-—even minor ones—should not drive a car.
