Hypoglossal nerve tumor: A tumor that develops on the hypoglossal nerve can cause compression of the nerve, leading to symptoms such as weakness or paralysis of the tongue muscles, difficulty swallowing, and speech problems. 3. Hypoglossal nerve injury: Trauma to the head or neck can cause injury to the hypoglossal nerve, leading to symptoms such as weakness or paralysis of the tongue muscles, difficulty swallowing, and speech problems. 4. Hypoglossal nerve inflammation: Inflammation of the hypoglossal nerve, such as that caused by an infection or autoimmune disorder, can lead to symptoms such as weakness or paralysis of the tongue muscles, difficulty swallowing, and speech problems. Treatment for hypoglossal nerve diseases depends on the underlying cause and severity of the condition. In some cases, surgery may be necessary to remove a tumor or repair an injury to the nerve. In other cases, medications or physical therapy may be used to manage symptoms and improve function.

Metal metabolism, inborn errors refer to genetic disorders that affect the body's ability to properly regulate the absorption, distribution, metabolism, and excretion of essential metals such as iron, copper, zinc, and manganese. These metals play important roles in various biological processes, including energy production, DNA synthesis, and immune function. Inborn errors of metal metabolism can result in a range of clinical manifestations, depending on the specific metal affected and the severity of the disorder. For example, disorders of iron metabolism can cause anemia, fatigue, and developmental delays, while disorders of copper metabolism can cause neurological problems, liver disease, and skin pigmentation abnormalities. Diagnosis of inborn errors of metal metabolism typically involves a combination of clinical evaluation, laboratory testing, and genetic analysis. Treatment may involve dietary modifications, supplementation with the deficient metal, or chelation therapy to remove excess metal from the body. Early diagnosis and appropriate management are important to prevent or minimize the long-term consequences of these disorders.

"Brain Diseases, Metabolic, Inborn" refers to a group of neurological disorders that are caused by genetic mutations or inherited metabolic disorders that affect the normal functioning of the brain.
