Cognition is the process of thinking and knowing things. Damage to the brain after a stroke can cause many cognitive changes. Doing things that once were easy may now be hard. Your loved one may not be aware of these problems. This puts them at greater risk for injury.
Why Is It Important to Get Help?
Changes in cognition are stressful for you and your loved one. Talk with your healthcare team. Professionals can do cognitive testing. They can suggest treatments and tips to deal with cognitive problems. Ask about a referral to a professional who specializes in cognitive problems. Below is a list of providers who can help:
- Neurologists or cognitive neurologists diagnose and treat memory problems.
- Neuropsychologists conduct tests and work with neurologists to treat problems.
- Occupational therapists and nurses suggest practical tips. They provide care in the office or the patient’s home.
Your local stroke associations can provide information. The Resources section has contact information for the American Stroke Association and the National Stroke Association.
What Do You Need to Know?
After a stroke, your loved one’s world is often confusing. Strokes affect people in different ways. For example, some stroke survivors have problems with perception or memory. Other survivors have problems learning or reasoning. Watching these changes in your loved one is difficult. It is normal to be anxious.
The following are tips that may help:
Join a caregiver support group or talk with others − Discussing your fears can help. Other stroke survivors and caregivers will understand. They can offer encouragement and ideas for dealing with cognitive problems. Learn more about stroke support groups.
Talk with other family members − Help them understand that stroke survivors often have cognitive problems.
Focus on what your loved one can still do − Build on the strengths and skills that weren’t lost. Avoid comparing your loved one to the way they used to be. Some of the changes may be permanent. Others will disappear over time.
Encourage your loved one to exercise their mind − Computer games may help regain thinking skills. Games like word puzzles, playing cards or dominoes may help.
Respect your loved one − Don’t assume they cannot understand you. Don’t talk down to your loved one.
What Is Disorientation?
Stroke survivors sometimes have trouble knowing what day it is. They may get lost or have trouble finding the bathroom. Being able to recognize friends and family members may be lost. This confusion can cause fear and embarrassment. There are ways you can help.
- Remind your loved one where they are. Talk about the time and day of the week. Discuss what is going to happen next.
- Be calm and gentle. Stress will increase your loved one’s confusion. Imagine how difficult it is for your loved one. Reassure your loved one that you are there to help.
- Have a daily routine. Do tasks at the same time each day.
- Place an easy-to-read digital clock on a bedside table.
- Hang a big calendar on the wall.
What Is Perception?
Perception involves making sense of what you see, hear, touch, smell and taste. Of all the senses, vision, hearing and touch are most often affected. Stroke survivors with visual problems may not recognize faces or familiar objects. They may have trouble judging distance and bump into things or misjudge steps.
Other survivors may have a loss of touch sensation. Some survivors may not feel pain or temperature. They may not be aware of being burned with hot water or cut with a sharp knife. Other stroke survivors may not feel the position of their arms or legs. This can cause problems when putting on a shirt or pants. These survivors may also have trouble walking. They may not know when their feet hit the ground. Other survivors may not recognize sounds like the phone ringing.
How Does Stroke Affect Your Loved One’s Perception?
How your loved one’s perception is affected depends on where the damage to the brain occurred. The right and left sides of the brain have different functions. In most people, the left side of the brain controls language. The left side of the brain controls the right side of the body. So, language problems are more common in persons who have right-sided weakness.
The right side of the brain helps us understand what we see, hear and touch. The right side also directs things, such as judging depth, size and distance. The right side of the brain controls the left side of the body. Persons with left-sided weakness have problems with vision, hearing and touch.

They may become easily distracted. It may be hard to do more than one thing at a time. They may have trouble staying on topic when talking with others. Attention problems improve for most people over time.
