The right hemisphere of the brain is responsible for several important thinking skills, according to the American Speech-Language-Hearing Association. These skills include attention, memory, reasoning, and problem-solving. Damage to the right hemisphere of the brain can lead to problems with these skills, and a person with right hemisphere brain damage may have trouble communicating with others. Additionally, the right side of the brain controls the left side of the body, so a person with right hemisphere brain damage may also have problems using their left arm or leg.

While there is a popular belief that the left and right hemispheres of the brain are distinct and control separate aspects of thinking, this is not entirely accurate. While the left hemisphere is primarily responsible for speech and abstract thinking, and the right hemisphere is responsible for image processing, spatial thinking, and movement in the left side of the body, the two sides of the brain work together and communicate with each other. However, there are some differences in what the left and right hemispheres do. For example, the right hemisphere is dominant in processing emotional responses, while the left hemisphere is dominant in language processing.
