Metabolic diseases affecting the nervous system

Metabolic diseases are disorders that occur when the body is unable to produce or use necessary metabolic products or processes. These diseases can affect any system of the body, but the nervous system is particularly vulnerable. Metabolic diseases that affect the nervous system can present in a variety of severe and disabling symptoms, including issues with movement, memory, vision, and other mental faculties. The most common metabolic diseases affecting the nervous system are lysosomal storage disorders, such as Tay–Sachs, Sandhoff, and Gaucher disease. These inherited conditions involve the accumulation of certain lipids, proteins, or carbohydrates in the body’s cells, which impair the cells’ normal functioning and can lead to neurological problems. Other metabolic diseases include mitochondrial diseases, in which the cells’ powerhouses have unfavorable genetic mutations, and Krebs cycle disorders, which disrupt the body’s processing of carbohydrates, proteins, and fats. Patients with metabolic diseases affecting the nervous system may show signs of neurological deficits such as difficulty with motor control and balance, cognitive impairments, and problems with vision. Other symptoms can include seizures, impaired concentration and attention, difficulty with language and communication, developmental delays, and behavioral issues. In severe cases, metabolic diseases can cause paralysis or coma. To diagnose metabolic diseases, clinicians will often order tests such as urine or blood analyses, genetic tests, MRIs, or brain scans. Treatments vary depending on the type of metabolic disease, but may include medications, infusions, physical therapy, lifestyle modifications, and, in some cases, surgery. Proper and prompt diagnosis and treatment of metabolic diseases is essential for minimizing their effects on the nervous system.
