A person who has had a stroke may act differently than he or she did before the stroke. This will depend on which part of the brain was affected, and how severe it was. A patient who had a stroke on the left side of the brain will act differently than a patient who had a stroke in the right side. It is important to remember that the changes are caused by the stroke, and may lessen or resolve over time.
Left hemisphere stroke--if the stroke occurred in the left side of the brain, the person may tend to be slow and cautious. Disorganization or hesitation may occur when trying new tasks. A person with this type of behavioral style may need guidance dong common tasks. They need positive feedback and what they are doing is okay.
Right hemisphere stroke--a person who has a stroke on the right side of the brain may have difficulty judging distance, size, position, speed of movement, and how parts relate to wholes. He or she may act impulsively, or too fast and may tend to overestimate their abilities and try to do things they cannot. He or she may act as if they are unaware that there are any problems. This behavioral style could cause an increased risk for falling or bumping into things. He or she may have difficulty dressing or picking up objects, and it would most likely be unsafe to drive a car. Checking how well the person with a right brain injury can actually do certain tasks will provide a more clear idea of how safe the person will be doing things on their own. They will also need encouragement to slow down and carefully check each step as it is completed.
