Question: what are the uses of vitamin e capsules

Reference:
Ataxia with vitamin E deficiency: Ataxia with vitamin E deficiency (AVED) is a progressive disease affecting motor control and movement. Symptoms of AVED include slurred speech ( dysarthria ), difficulty coordinating movements ( ataxia), numbness in the hands and feet ( peripheral neuropathy ), and progressive leg weakness. Some affected individuals may experience vision loss due to damage to the back of the eye ( retinitis pigmentosa). Symptoms typically begin during childhood or adolescence and worsen with age, resulting in the need for a wheelchair by early adulthood. AVED is caused by a mutation to the TTPA gene . When this gene is damaged, vitamin E cannot be distributed throughout the body. Vitamin E is important because it protects the cells of the neurological system (neurons) from dangerous molecules called free radicals. AVED is inherited in an autosomal recessive manner. Treatment for AVED includes vitamin E supplements, which will prevent AVED from developing if given before symptoms begin and may reverse some neurological symptoms if begun after AVED develops. [1] [2] The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.

AVED may be suspected in individuals who have the following findings at the beginning of puberty: [2] Progressive ataxia Clumsiness of the hands Loss of the ability to know where one's body is in space (proprioception) Absent reflexes (areflexia) The inability to perform rapid, alternating movements (dysdiadochokinesia) A tendency to sway or fall while standing upright with the feet together, arms stretched out and the eyes closed (positive Romberg sign) A nodding movement of the head (titubation) Decreased visual sharpness (acuity) Positive Babinski sign (upward movement of the big toe and fanning of the feet after the sole of the foot has been firmly stroked) Macular atrophy (wasting away of the cells that form the part of our eye responsible for central vision) Retinitis pigmentosa ( eye disease in which there is damage to the retina) Laboratory studies typically show a reduced plasma vitamin E concentration but normal levels of lipoproteins ( proteins that combine with and transport fat or other lipids in the blood). Other studies that may be useful include: nerve conduction studies, brain imaging , and studies of nerve tissues . [2] [3] Although no universal diagnostic guidelines are available, researchers suggest that diseases that cause fat malabsorption, such as abetalipoproteinemia should be ruled out. Genetic testing finding two TTPA gene mutations may be useful to confirm the diagnosis. [2] [3] Testing Resources The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. Treatment for AVED requires lifelong high dose supplementation of vitamin E. When treated early, some symptoms, such as ataxia and intellectual decline, can be reversed. In older patients, treatment may slow disease progression, but some symptoms remain. [2] [3] Research indicates that if vitamin E treatment is initiated in presymptomatic individuals with two mutations in the TTPA  gene (e.g., younger sibs of an affected individual), the symptoms of AVED will not develop. [2] Management Guidelines GeneReviews provides current, expert-authored, peer-reviewed, full-text articles describing the application of genetic testing to the diagnosis, management, and genetic counseling of patients with specific inherited conditions.

Answer: Ataxia with vitamin E deficiency (AVED) is a progressive disease affecting motor control and movement. Treatment for AVED includes vitamin E supplements, which will prevent AVED from developing if given before symptoms begin and may reverse some neurological symptoms if begun after AVED develops.
