Treatment and Daily Management

At a Glance

Adult polyglucosan body disease has no cure, so treatment focuses on protecting bladder and kidney function, managing spasticity and mobility problems, preventing falls, and preserving quality of life. Triheptanoin and extreme diets have not been shown to stop or reverse APBD.

Because there is currently no cure for APBD, your medical care will focus on symptom management—tailoring treatments to improve your mobility, protect your organs, and maintain your quality of life. This requires a multidisciplinary team of specialists, including neurologists, urologists, and physical therapists, who work together to address the different ways the disease affects your body [1][2].

Managing Your Bladder and Kidney Health

The most critical part of daily APBD management is monitoring your neurogenic bladder. When the bladder doesn’t empty fully, incomplete emptying, high bladder pressures, urine reflux, and recurrent infections can cause permanent kidney damage [3][4].

  • Intermittent Catheterization: If your bladder cannot empty on its own, your neuro-urologist may recommend clean intermittent catheterization (CIC) after assessing your post-void residual and bladder pressures, often using a urodynamic study. This involves using a small, disposable tube several times a day to fully drain the bladder. While highly useful to prevent overflow accidents and protect kidneys, it is not automatically required for every patient and carries risks like urethral trauma or infection [4].
  • Medications: Doctors may prescribe drugs to help the bladder relax (for urgency) or to help the “neck” of the bladder open more easily. Safety warning: Bladder-relaxing drugs (antimuscarinics) can worsen urinary retention and cognitive side effects, while alpha-blockers can worsen low blood pressure. Do not start, stop, or change these without your treating clinician [4].
  • Vigilance: You must stay alert for signs of a Urinary Tract Infection (UTI). In APBD, a severe UTI can cause a sudden, temporary “crash” in your ability to walk or think clearly [4].

Mobility, Spasticity, and Balance

Managing the stiffness (spasticity) in your legs is a delicate balance. The goal is to reduce discomfort without making your muscles so relaxed that they become too weak to support your weight [5].

  • Physical Therapy: Regular stretching and “task-specific” training (like balance and gait exercises) are essential. Some specialized centers use robot-assisted gait training to help maintain walking patterns [6][7].
  • Medications: Oral drugs like baclofen or tizanidine can help reduce muscle tightness. Because these can cause severe sleepiness, weakness, dizziness, and falls, your doctor will likely start with a very low dose. Baclofen should never be stopped abruptly [5][8].
  • Assistive Devices: Using a cane, walker, or wheelchair is not a “defeat”—it is a tool to stay active and prevent dangerous falls [9].
  • Blood Pressure Support: If you feel dizzy when standing (orthostatic hypotension), simple steps like wearing compression stockings and staying well-hydrated can help stabilize your blood pressure [10]. Note that this advice must be balanced against any kidney, heart, or bladder restrictions you have.

What the Research Says About Diet and Triheptanoin

You may find information online about specialized diets or a synthetic oil called triheptanoin. It is important to know the results of the clinical trials:

  • Triheptanoin Trials: In a study of 23 adults with APBD, triheptanoin was compared to a placebo. After one year, there was no statistically significant benefit in how far patients could walk, their stair-climbing ability, or their overall symptoms. It is not an established disease-modifying treatment [11].
  • Metabolic Diets: While nutrition is important for general health, high-fat/low-carbohydrate (ketogenic-style) diets have not been proven to stop or reverse the progression of APBD. Extreme diets should not be attempted outside individualized nutritional supervision, as they can cause harm [11][12].

Future Horizons: Preclinical Research

While there are no disease-modifying treatments available for humans today, scientists are working on several exciting “preclinical” (animal and cell-based) strategies:

  • Glycogen Synthase Suppression: Researchers have found that reducing the amount of glycogen your body makes in the first place can prevent the buildup of toxic polyglucosan bodies in mice [13][14].
  • Gene Editing (CRISPR): Early studies in mice have used CRISPR technology to “turn down” the production of problematic glycogen enzymes [15].
  • Antisense Oligonucleotides (ASOs): For patients with specific genetic mutations, ASOs are being developed in laboratory human cells to help the body “skip over” the error. This approach is mechanism-specific and not yet ready for human trials [16][17].

These technologies represent the next wave of research, but they must undergo years of safety testing before they can be used in patients. In the meantime, your best approach is proactive, multidisciplinary care.

Common questions in this guide

What treatment is available for adult polyglucosan body disease?
There is currently no cure for adult polyglucosan body disease. Treatment focuses on managing symptoms, protecting bladder and kidney function, supporting movement, reducing fall risk, and maintaining quality of life with help from a multidisciplinary care team.
When might someone with APBD need intermittent catheterization?
Clean intermittent catheterization may be recommended when the bladder does not empty fully or bladder pressures could threaten the kidneys. A clinician usually considers symptoms, the amount of urine left after urinating, and bladder-pressure testing; catheterization is not automatically needed for every person and can carry risks such as infection or urethral injury.
How can APBD care help protect the kidneys?
Kidney protection depends on monitoring bladder emptying and pressure, addressing urinary retention, and watching for urinary tract infections. Clinicians may also check kidney function and the upper urinary tract over time, then adjust bladder treatments based on the results.
What can help stiffness and walking problems caused by APBD?
Physical therapy with stretching, balance work, gait practice, and task-specific training can support mobility. Baclofen or tizanidine may reduce muscle tightness, while canes, walkers, wheelchairs, or specialized gait training can improve safety; these options must be balanced against weakness, sleepiness, dizziness, and falls.
Can APBD medicines make urinary retention, dizziness, or weakness worse?
Yes. Bladder-relaxing medicines can worsen urinary retention or cause cognitive side effects, alpha-blockers can lower blood pressure, and baclofen or tizanidine can cause sleepiness, weakness, or dizziness. Do not start, stop, or change these medicines without discussing them with your treating clinician.
Does triheptanoin or a ketogenic diet slow adult polyglucosan body disease?
In a trial involving 23 adults with APBD, triheptanoin did not significantly improve walking distance, stair climbing, or overall symptoms after one year, so it is not an established disease-modifying treatment. Ketogenic-style diets have not been proven to stop or reverse APBD, and extreme diets may be harmful without individualized nutritional supervision.
Are gene editing or antisense treatments available for APBD?
Gene editing, glycogen-production suppression, and antisense strategies are being studied in animals or laboratory cells. They are not currently established treatments for people and require further safety testing before human use; a specialist can help identify legitimate clinical trials or natural history studies.
