What are common behaviors with a right brain stroke?

A person with a right brain stroke may show:

  • Impulsive behavior
  • Rambling speech or actions
  • Trouble paying attention
  • Poor memory
  • Short attention span
  • Disregard for left side
  • Lack of awareness of effects of stroke (overestimates ability)

These behaviors make the person a SAFETY RISK. A safety risk means that a person is not safe to be left without close supervision to protect him or her from harm.

Helpful Suggestions:

  • Approach from left side. Makes the person more aware of left side to help with left-sided neglect.
  • Slow the person down if moving too fast. Moving too fast could cause harm or injury (impulsive).
  • Sit next to the person. Place hand on the arm to silence or limit behavior. Helps stop or limit inappropriate behavior.
  • Keep a day-to-day routine. Repetition will help memory.
  • Give reminders and simple directions to finish task.
  • Needs reminders to finish task (short attention span).
  • Point out effects of a stroke. Reminds the person of problems and increases awareness (overestimates ability).
