The right cerebellum is a small portion of the brain that is responsible for controlling much of the movement involving the right side of the body. This differs greatly from most areas of the brain, because the right side of the brain usually controls the left side of the body. The right cerebellum is located at the back of the head, just behind the portion of the brain known as the cerebrum. Some studies indicate a possible link between acquired dyslexia and abnormalities in the right cerebellum. Some medical conditions that may affect the proper functioning of this area of the brain include traumatic brain injury, multiple sclerosis, and stroke.
Some of the functions of the right cerebellum include coordination of balance, muscle tone, and equilibrium involving the right side of the body. This area of the brain also helps to control voluntary muscle movements. Due to its location, the right cerebellum is naturally more protected from traumatic injury than other areas of the brain, although damage is still possible. Unfortunately, this protection does not extend to natural disease processes such as stroke or multiple sclerosis.
Potential symptoms that may indicate damage to the right cerebellum include slow, uncoordinated movements such as staggering when walking. In order to compensate for this deficiency, the affected person may develop a wider gait than normal, although this may only be noticeable to others. The ability to accurately judge distances or to stop suddenly may be compromised when there is damage to this portion of the brain.
Fine motor skills are controlled in part by the right cerebellum. When an injury has occurred, the affected person may begin to have difficulty writing or picking up small objects with the right hand. Mobility may be limited due to a loss of ability to control movement of the right arm or leg. Depending on the cause of the injury, damage to this portion of the brain can be temporary or permanent. It is important to consult a doctor if any potential signs of brain injury are present so that any severe medical issues can be diagnosed and treated as early as possible.
Occasionally, a person is born with abnormalities involving the cerebellum. These congenital issues are usually diagnosed early in life due to the obvious coordination issues that are present. Inherited disorders may also lead to a progressive degeneration of this area of the brain, causing the patient to slowly lose coordination. These conditions rarely respond to any form of treatment, as brain cells are not able to regenerate once they have become damaged.
