What is Metachromatic Leukodystrophy?
Metachromatic leukodystrophy (MLD) is a rare genetic disorder that affects the nervous system. It is caused by a deficiency of an enzyme called arylsulfatase A. This enzyme is responsible for breaking down certain fatty substances in the body, known as sulfatides. As a result of this deficiency, sulfatides build up in the brain and nervous system, causing damage to the myelin sheath, the protective covering around nerve cells. There are three classifications of MLD, based upon initial display of symptoms: late-infantile onset (6months – 4 years of age), juvenile onset (4 – 16 years of age), and adult onset (16 years of age and older).
Causes & Symptoms of MLD
MLD is typically inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the impacted gene for their child to develop the disorder. Symptoms of MLD usually appear in early childhood and can vary in severity. Symptoms present in different ways based upon classification. The overarching common symptoms include developmental delays, loss of motor skills, muscle stiffness, seizures, and behavioural changes.
The Impact of Exercise and other Available Treatments
Currently, there is no cure for MLD, but there are treatments available to help manage symptoms and improve quality of life. One of the most common treatments is called hematopoietic stem cell transplantation, which involves replacing the defective cells with healthy cells from a donor. This treatment can slow the progression of the disease and may help improve some symptoms.
In addition to medical treatments, physical therapy and exercise can also play a crucial role in managing MLD symptoms. Regular exercise can help improve muscle strength, flexibility, and mobility, which are often affected by the disease. It can also help improve balance and coordination, making activities of daily living easier for those with MLD.
Exercise programs for individuals with MLD should be tailored to their specific needs and abilities. Prescribed exercise should include aspects such as stretching, light resistance training, and balance exercises. It is important for individuals with MLD to work with an accredited exercise physiologist who has experience working with neurological conditions to ensure they are engaging in safe and effective exercises.
While MLD is a devastating and progressive disease, there are treatments and interventions available to help manage symptoms and improve quality of life. Incorporating regular exercise into a comprehensive treatment plan can help individuals with MLD maintain function and mobility for as long as possible.
