A right-brain stroke causes damage to the right side of a person's brain, which is responsible for nonverbal communication, spatial awareness and the regulation of emotions, according to the American Speech-Language-Hearing Association. A person with a right-brain injury resulting from a stroke may exhibit poor judgment, short-term memory loss and a short attention span.
Damage to the right side of the brain causes problems on the left side of the body, notes the American Stroke Association. Sufferers of a right-brain stroke can experience full or partial paralysis or weakness on the left side of the face and body. They may also neglect the left side of the body or have trouble seeing anything to the left of the body. Because the right side of the brain is responsible for spatial awareness, which allows individuals to judge distance, space, size and speed, a right-brain stroke sufferer is prone to falling.
Individuals often have poor decision-making skills following a right-brain stroke, according to UW Health. Organizational skills and orientation to place and time are often also affected, states the American Speech-Language-Hearing Association.
Warning signs of a stroke include facial drooping, arm weakness and difficulty speaking, explains the American Stroke Association. If stroke symptoms are suspected, seek immediate medical attention from a licensed health care practitioner.
