Bronze-Schilder disease is an older name for X-linked adrenoleukodystrophy (ALD), a genetic disorder caused by harmful changes in the ABCD1 gene. This gene makes a transporter protein in tiny cell parts called peroxisomes. When the transporter does not work, very-long-chain fatty acids (VLCFAs) build up, especially in brain white matter, the adrenal glands, and sometimes the testes. The fatty-acid buildup can damage the insulating myelin around nerves and can also cause primary adrenal insufficiency (Addison disease). Illness patterns vary. Some boys develop fast brain inflammation and demyelination. Some men develop a slow, stiff-spastic walking problem (adrenomyeloneuropathy). Some people first show only adrenal failure. Women who carry the gene can develop a mild to moderate walking problem later in life. NCBI+1PMC
Bronze-Schilder disease is an older name for X-linked adrenoleukodystrophy (X-ALD). It is a genetic disease that mostly affects boys and men. A change (mutation) in the ABCD1 gene stops a peroxisome transporter from removing very-long-chain fatty acids (VLCFAs) from cells. These fatty acids build up in the brain white matter, the adrenal glands, and the testes. The buildup can slowly damage myelin (the insulation around nerves), cause adrenal gland failure, and lead to behavior changes, learning problems, weakness, stiffness, seizures, and vision or hearing problems. Some boys develop a fast “cerebral” form with brain inflammation. Some adults develop a spinal cord form with stiffness and walking troubles. Many patients also develop Addison’s disease (adrenal failure) with dark skin, fatigue, weight loss, and low blood pressure. Early diagnosis and early treatment are very important. NCBIPMCPubMed
Important note: Bronze-Schilder (ALD) is not the same as “Schilder’s disease” (myelinoclastic diffuse sclerosis), a different rare demyelinating condition. The old names overlap historically and can be confusing. BrainFactsPMC
Other names
Bronze-Schilder disease has many historical synonyms: Addison-Schilder disease, Schilder-Addison syndrome, Siemerling-Creutzfeldt disease, melanodermic leukodystrophy, diffuse (sudanophilic) cerebral sclerosis, X-linked adrenoleukodystrophy (X-ALD), and the adult form adrenomyeloneuropathy (AMN). Modern medical systems (MeSH, Disease Ontology) list “Bronze-Schilder disease” as an exact synonym for adrenoleukodystrophy. NCBIdisease-ontology.orgZFIN
Types
Childhood cerebral ALD (CCALD). Usually boys aged ~4–10. Rapid brain inflammation and demyelination. Without treatment, decline can be fast. NCBIPMC
Adolescent or adult cerebral ALD. Similar brain process, but later onset. NCBI
Adrenomyeloneuropathy (AMN). Adult-onset stiff, spastic legs, balance problems, bladder and sexual dysfunction from spinal cord and peripheral nerve involvement. Progresses slowly. NCBI
Isolated adrenal insufficiency. Some individuals first show only Addison disease (fatigue, weight loss, low blood pressure, skin darkening) before any brain or spinal symptoms appear. NCBI
Females with ABCD1 variants. Many are symptom-free in youth, but a significant number develop later-life myelopathy (stiff gait, pain). NCBI
Causes
In genetics, the true “cause” is the ABCD1 variant. The items below describe the root cause and the downstream biological mechanisms that drive damage.
ABCD1 gene variant (X-linked). The basic cause; it disrupts a peroxisomal transporter. PMC
VLCFA transport failure. Faulty ABCD1 cannot move VLCFAs into peroxisomes for breakdown. BioMed Central
VLCFA buildup in cells. Excess C24:0 and C26:0 accumulate, especially in brain and adrenals. NCBI
Myelin membrane stress. VLCFAs disrupt normal lipid balance in myelin and cell membranes. BioMed Central
Microglial activation and inflammation. The brain’s immune cells become overactive in lesions. BioMed Central
Oxidative stress. Abnormal lipids may increase reactive oxygen species that injure cells. BioMed Central
Mitochondrial dysfunction. Altered membranes can disturb energy production in mitochondria. BioMed Central
Blood–brain barrier changes. Inflammatory injury allows lesions to expand. (Inference from inflammatory demyelination literature in ALD.) BioMed Central
Auto-inflammatory demyelination cascade. Once started, immune damage can spread through white matter. BioMed Central
Adrenal cortical cell toxicity. VLCFAs harm adrenal cells, causing cortisol deficiency. NCBI
Leydig cell involvement. Testicular cells may be affected, lowering testosterone in some males. Wikipedia
ELOVL1 pathway contribution. Body makes VLCFAs endogenously; upregulated synthesis worsens load. NCBI
Genetic background (modifiers). Different ABCD1 variants and modifiers may shift phenotype. Lippincott Journals
Age-related vulnerability. Brain development stages may influence onset (childhood cerebral vs adult AMN). PMC
Hormonal stressors. Untreated adrenal failure lowers stress tolerance and can unmask disease. Oxford Academic
Infections/fever as stressors. Systemic stress can worsen adrenal insufficiency and neurological symptoms (clinical inference consistent with adrenal physiology). Oxford Academic
Nutritional fatty-acid balance. Diet supplies some VLCFAs, but most are produced in the body; diet alone is not the primary cause. NCBI
Peroxisomal biology limits. Peroxisomes are the only place that can break down VLCFAs efficiently; when they fail, backup systems cannot compensate. PMC
White-matter tract susceptibility. Posterior brain regions (parieto-occipital) are often first hit. PMC
Female X-inactivation variability. In women, random X-inactivation can lead to symptoms later in life. NCBI
Common symptoms
Learning or behavior change in boys. Trouble in school, attention loss, irritability—often early signs of cerebral involvement. NCBI
Vision problems. Blurred vision or loss of peripheral vision from occipital white-matter damage. PMC
Hearing or speech difficulty. Pathways for language and auditory processing can be affected. NCBI
Seizures. Inflammatory demyelination can trigger seizures. NCBI
Headache and vomiting. Sometimes occur with active brain lesions. BrainFacts
Weakness and clumsiness. Damage to motor tracts causes weakness and poor coordination. NCBI
Stiff, spastic gait (AMN). Adult men often develop leg stiffness, balance issues, and falls. NCBI
Numbness or burning pain. Peripheral nerve involvement may cause sensory symptoms. NCBI
Bladder and bowel problems. Spinal cord involvement can cause urgency, retention, or constipation. NCBI
Sexual dysfunction. Erectile or ejaculatory problems can occur in AMN. NCBI
Fatigue and muscle weakness from adrenal failure. Low cortisol reduces energy and stress tolerance. Oxford Academic
Weight loss and low appetite. Common in chronic adrenal insufficiency. Oxford Academic
Skin darkening (“bronze” hyperpigmentation). High ACTH stimulates melanin in primary adrenal failure. Oxford Academic
Dizziness or fainting (orthostatic hypotension). Low aldosterone/cortisol lowers blood pressure. Oxford Academic
Adrenal crisis (medical emergency). Sudden vomiting, severe weakness, low blood pressure, shock during illness or stress. Oxford Academic
Diagnostic tests
A) Physical examination
Neurologic exam. The clinician checks strength, tone, reflexes, coordination, and gait. Spasticity, brisk reflexes, and Babinski signs suggest white-matter or spinal cord involvement. NCBI
Cognitive and behavior assessment. School performance, memory, attention, and mood changes may point to cerebral disease. NCBI
Skin inspection for hyperpigmentation. Diffuse “bronze” darkening supports adrenal insufficiency. Oxford Academic
Orthostatic vital signs. Blood pressure drop when standing suggests mineralocorticoid deficiency. Oxford Academic
Genital exam in males. Testicular size and signs of hypogonadism may be reduced in some patients. Wikipedia
B) Manual bedside tests
Manual muscle testing (MRC grading). Rates limb strength to track weakness over time.
Tone and spasticity check (e.g., Modified Ashworth). Detects stiffness typical of AMN.
Heel-to-toe walk and Romberg test. Screens balance and proprioception for spinal tract involvement.
Visual acuity and color vision (Snellen/Ishihara). Simple checks for vision pathway dysfunction. PMC
Reflex and plantar responses. Hyperreflexia and extensor plantar responses suggest corticospinal tract disease.
(Items 6–10 are standard neuro exam maneuvers; they help quantify deficits but are not disease-specific.)
C) Laboratory and pathological tests
Plasma VLCFA profile. Elevated C26:0 and high C24:0/C22:0 and C26:0/C22:0 ratios strongly suggest ALD in males. NCBI
Dried blood spot C26:0-LPC (newborn screening). Many programs screen newborns with this marker; positives need confirmatory testing. ARUP Consulthrsa.govMDPI
ABCD1 genetic testing. Sequencing confirms the diagnosis and enables family testing. NCBI
ACTH and morning cortisol. High ACTH with low cortisol indicates primary adrenal insufficiency. Oxford Academic
Cosyntropin (ACTH) stimulation test. Measures adrenal reserve; abnormal rise supports adrenal failure (note: can be normal in very early disease). Oxford AcademicNCBI
Plasma renin and aldosterone. Elevated renin with low aldosterone supports mineralocorticoid deficiency. Oxford Academic
Rule-out labs for other causes. 21-hydroxylase antibodies for autoimmune Addison, metabolic panels, thyroid tests—help exclude other reasons for symptoms. ScienceDirect
D) Electrodiagnostic tests
Nerve conduction studies and EMG. Detect peripheral neuropathy contributing to numbness or weakness. NCBI
Visual evoked potentials (VEP). Sensitive to optic pathway demyelination, sometimes abnormal even before symptoms. PMC
EEG. Used if seizures are present to characterize brain electrical activity.
E) Imaging tests
Brain MRI (T2/FLAIR). Classic parieto-occipital symmetric lesions, often with contrast enhancement in active disease; this is a cornerstone test. PMC
Loes score on MRI. A standardized severity score that tracks lesion extent and correlates with disability. PMCSAGE Journals
MR spectroscopy. Shows low N-acetylaspartate (NAA) and other changes that indicate neuronal loss in affected areas. ScienceDirect
Spinal MRI. In AMN, may show spinal cord atrophy consistent with myelopathy. NCBI
Adrenal imaging (optional). Imaging is usually not diagnostic for ALD, but may rule out other adrenal problems if needed.

Frequently asked questions
Is Bronze-Schilder disease the same as ALD?
Yes. It is an historical synonym for X-linked adrenoleukodystrophy. NCBIWhy “bronze”?
Because adrenal failure can cause dark skin (hyperpigmentation). WikipediaWhat gene is involved?
ABCD1 on the X chromosome. PMCDo all patients get brain disease?
No. Some have only adrenal failure for years; others develop the spinal cord (AMN) form; some boys develop the fast cerebral form. PMCHow is ALD diagnosed?
VLCFA blood test, ABCD1 gene test, adrenal tests, and MRI of the brain. PubMed+1PMCWhat is the MRI Loes score?
A scoring system that rates lesion burden and helps decide timing of HSCT. PubMedDoes Lorenzo’s oil cure ALD?
No. It can lower VLCFA levels and may help in early, asymptomatic boys but does not fix established brain disease. PubMedADCWhat treatment can stop early cerebral ALD?
HSCT or gene therapy (Skysona) may halt progression when done early in “active” disease, before major disability. ASTCT JournalU.S. Food and Drug AdministrationIs Skysona safe?
It can help some boys, but the label now carries warnings about blood cancers; strict monitoring is required. U.S. Food and Drug Administration+1Do girls/females get ALD?
Female carriers can develop symptoms, usually later and milder; they need monitoring. PMCWhat about adrenal crisis?
It is an emergency with vomiting, severe weakness, low blood pressure, or fainting. Give emergency hydrocortisone if trained and go to ER. WikipediaCan diet alone treat ALD?
No. Diet supports health and may be part of VLCFA management, but it does not replace HSCT/gene therapy in early cerebral disease. PubMedHow often do we need MRI?
Specialists schedule regular MRIs in at-risk boys to catch early changes; timing depends on age and prior scans. PubMedIs Schilder’s disease the same as ALD?
The term “Schilder’s disease” can also mean a different demyelinating illness. Use X-linked ALD to be precise. BrainFactsWhere should we get care?
At centers with ALD/HSCT/gene therapy experience so timing and risks are carefully managed. ASTCT Journal
