Categories:

Adult polyglucosan body disease (APBD) affects the nervous system.[1] People with this disease usually begin to show signs after the age of 40.[2] Signs and symptoms include trouble walking due to peripheral neuropathy and muscle weakness and stiffness. People with APBD also develop problems with bladder control due to damage to the bladder's nerves (neurogenic bladder). About half of people with APBD also develop dementia.[1][2] APBD can be caused by mutations in the GBE1 gene and inheritance is autosomal recessive. In some cases, the cause is not known.[1] Treatment aims to improve quality of life by controlling each symptom of the disease.[2] APBD likely shortens life expectancy, but with symptom management and supportive care, people with APBD can have years of productive life.[2]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

The exact prevalence of adult polyglucosan body disease (APBD) is unknown, but the disease is considered rare. At least 70 people with APBD have been reported in the medical literature.[1] The disease appears to affect males and females equally.[3]

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources


Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.

Conditions with similar signs and symptoms from Orphanet
The motor neuron dysfunction seen in APBD may be similar to that seen in amyotrophic lateral sclerosis (see this term). Primary urologic dysfunction, multiple sclerosis and Alzheimer's disease should also be considered, as well as other causes of adult onset myeloneuropathy and leukoencephalopathy.
Visit the Orphanet disease page for more information.

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Patient Registry

  • A registry supports research by collecting of information about patients that share something in common, such as being diagnosed with Adult polyglucosan body disease. The type of data collected can vary from registry to registry and is based on the goals and purpose of that registry. Some registries collect contact information while others collect more detailed medical information. Learn more about registries.

    Registries for Adult polyglucosan body disease:
    APBDRF FAN Natural History Study
     

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
