Bilateral striopallidodentate calcinosis (BSPDC) is a rare brain condition where calcium-rich deposits build up on both sides of deep brain areas that control movement and thinking—especially the striatum, globus pallidus, and dentate nuclei. These deposits are usually seen first on a non-contrast CT scan. People may have movement problems (like stiffness, tremor, imbalance, dystonia, or parkinsonism), seizures, headaches, speech/swallowing trouble, mood or thinking changes, or sometimes no symptoms at all. Some cases run in families (now called PFBC) and are linked to genes such as SLC20A2, PDGFB, PDGFRB, XPR1, MYORG, JAM2, OCLN. Other cases are secondary to treatable causes (for example, low parathyroid hormone). There is no proven medicine that removes the calcifications, so care focuses on finding and treating secondary causes and controlling symptoms. SpringerLink+4NCBI+4NCBI+4

Bilateral striopallidodentate calcinosis is a brain condition where tiny calcium deposits build up in deep brain areas on both sides. The word “strio-pallido-dentate” points to the parts most often involved: the striatum (caudate and putamen), the globus pallidus, and the dentate nucleus of the cerebellum. These deposits are usually seen best on a head CT scan. The condition can be primary (genetic; also called primary familial brain calcification) or secondary to another disease like low parathyroid hormone. Symptoms, if they occur, often include movement problems, speech changes, thinking or mood problems, or seizures. NCBI+1

Other names

This condition is also known as Fahr disease (for primary/idiopathic cases) and Fahr syndrome (for secondary causes). Other names include primary familial brain calcification (PFBC), idiopathic basal ganglia calcification (IBGC), and calcinosis nucleorum. The descriptive term bilateral strio-pallido-dentate calcinosis highlights the typical brain regions. NCBI

Types

1) Primary (genetic) PFBC.
Calcium builds up because of inherited changes in certain genes. It often runs in families, sometimes with age-dependent penetrance (some carriers stay well for years). The most commonly affected regions are the basal ganglia, thalamus, cerebellum, and subcortical white matter. NCBI

2) Secondary (Fahr “syndrome”).
Here, the calcification comes from another problem such as low parathyroid hormone, chronic kidney disease, infections, toxins, or rare genetic syndromes that are not the classic PFBC genes. Treating the underlying condition is the goal. NCBI+1

3) Age-related (physiologic) calcification.
Small basal ganglia calcifications may be seen in otherwise healthy older adults and are often found by chance on CT. These are usually mild and cause no symptoms. NCBI

Researchers think minerals deposit around small blood vessels in these deep brain regions. In PFBC, gene changes disturb how brain cells handle phosphate, growth-factor signaling, or small-vessel function, which favors calcium phosphate deposition. In secondary cases, disturbed calcium-phosphate balance (for example from hypoparathyroidism) and other processes trigger similar deposits. NCBI+1

Causes

1) SLC20A2-related PFBC.
Changes in the SLC20A2 gene (PiT-2 phosphate transporter) are the most common PFBC cause. They impair phosphate handling, encouraging calcium-phosphate to precipitate in vessel walls and surrounding tissue. NCBI

2) PDGFB-related PFBC.
Variants in PDGFB affect platelet-derived growth factor B signaling important for brain small vessels (pericytes). Vessel dysfunction promotes calcification. NCBI

3) PDGFRB-related PFBC.
Changes in PDGFRB (the receptor for PDGF-B) similarly disrupt signaling at the blood–brain barrier and small vessels, enabling deposits to form. NCBI

4) XPR1-related PFBC.
XPR1 helps export phosphate from cells. Faulty export raises local phosphate levels and favors calcium phosphate crystals. NCBI

5) MYORG-related PFBC (autosomal recessive).
MYORG variants often cause symptom onset in mid-life with widespread calcifications, including brainstem. Heterozygous carriers may show CT changes with few or no symptoms. NCBI

6) JAM2-related PFBC (autosomal recessive).
JAM2 variants cause early adult onset and high penetrance. They affect endothelial junctions and small-vessel integrity, promoting calcification. NCBI

7) CMPK2-related PFBC (autosomal recessive).
CMPK2 encodes a mitochondrial enzyme. Its disruption links energy metabolism to abnormal mineral deposition in brain microvessels. NCBI

8) NAA60-related PFBC (autosomal recessive).
NAA60 encodes an acetyltransferase. Recently reported families show early onset, mostly motor symptoms, and extensive multi-region calcifications. NCBI

9) Idiopathic hypoparathyroidism.
Low parathyroid hormone lowers calcium and raises phosphate in blood. This promotes calcium-phosphate deposition in basal ganglia and other regions. NCBI

10) Post-surgical hypoparathyroidism.
Accidental removal or injury of parathyroid glands during thyroid surgery can cause chronic hypocalcemia and calcifications if not corrected. NCBI

11) Pseudohypoparathyroidism (GNAS-related).
In this disorder, tissues resist parathyroid hormone. Calcium falls, phosphate rises, and basal ganglia calcifications can develop over time. NCBI

12) Kearns–Sayre syndrome (large mtDNA deletions).
This mitochondrial disease often shows globus pallidus calcification with ataxia, ophthalmoplegia, and heart block, usually before age 20. NCBI

13) MELAS (mitochondrial encephalomyopathy).
Some individuals with MELAS show bilateral basal ganglia calcifications on imaging along with strokes-like episodes and lactic acidosis. NCBI

14) Congenital infections (CMV, toxoplasmosis, rubella, herpes).
Perinatal infections can cause intracranial calcifications, often including basal ganglia, with seizures or developmental problems. NCBI

15) HIV infection.
HIV-related brain disease, opportunistic infections, or treatment history may be associated with basal ganglia calcifications in some cases. NCBI

16) Neurocysticercosis.
Parasite cysts may calcify, sometimes in basal ganglia, leaving ring-enhancing lesions that later become calcified nodules. NCBI

17) Aicardi–Goutières syndrome.
An interferon-mediated encephalopathy with early onset, developmental delay, and characteristic basal ganglia calcifications. NCBI

18) Cockayne syndrome.
A DNA-repair disorder; patients can have basal ganglia, cerebellar, and cortical calcifications with growth failure and photosensitivity. NCBI+1

19) Tuberous sclerosis complex.
Subependymal nodules and cortical tubers can calcify over time; neurologic features vary by age and lesion load. NCBI

20) Toxic or iatrogenic exposures.
Lead or mercury exposure, excess vitamin D, prior cranial radiation, and methotrexate therapy have all been reported with intracranial calcifications. NCBI

Symptoms

1) Slowness and stiffness (parkinsonism).
People may move slowly, feel rigid, and have reduced arm swing. This reflects basal ganglia circuit dysfunction. NCBI

2) Tremor.
A fine shaking at rest or with posture can occur. It may be mild or interfere with tasks like writing or holding a cup. NCBI

3) Dystonia.
Sustained twisting or abnormal postures can affect the neck, face, limbs, or trunk due to aberrant basal ganglia signaling. NCBI

4) Chorea or fidgety movements.
Brief, dance-like, unpredictable movements may appear in the hands, face, or trunk. NCBI

5) Gait imbalance and ataxia.
Unsteady walking and poor coordination, especially with turns, are common when cerebellar dentate nuclei are involved. NCBI

6) Speech changes (dysarthria).
Speech may become slurred, slow, or monotonous because of impaired coordination of tongue and facial muscles. NCBI

7) Swallowing trouble (dysphagia).
Some people choke on liquids or solids. This raises aspiration risk and should be assessed. NCBI

8) Seizures.
Both focal and generalized seizures can occur, sometimes the first sign in adults. Frontiers

9) Headache or migraine.
Head pain is reported in PFBC and may reflect altered networks or comorbid disorders. NCBI

10) Memory and thinking problems.
Short-term memory, planning, attention, and processing speed can decline. Severity does not always match calcification load. NCBI

11) Depression.
Low mood, loss of interest, and fatigue are frequent and may need active treatment. NCBI

12) Anxiety or irritability.
Worry, tension, and restlessness can accompany other symptoms and affect quality of life. NCBI

13) Psychosis (less common).
Hallucinations or delusions may occur in a subset, especially with extensive disease or later life onset. NCBI

14) Sleep disturbance.
Insomnia or fragmented sleep may worsen daytime function and mood. NCBI

15) Falls and injuries.
Poor balance, rigidity, and slowness increase fall risk and can lead to fractures if not addressed. NCBI

Diagnostic tests

A) Physical examination

1) General and vital signs.
The clinician checks blood pressure, weight, and signs of endocrine problems (for example, muscle cramps or tingling from low calcium). This helps decide which lab tests to order. NCBI

2) Full neurological exam.
Cranial nerves, muscle tone, strength, reflexes, sensation, coordination, and mental status are reviewed to map which systems are involved. NCBI

3) Movement-disorder exam.
The examiner rates tremor, rigidity, bradykinesia, and postural stability to document baseline severity and follow change. NCBI

B) Manual (bedside) tests

4) Finger-to-nose test.
You touch your nose and the examiner’s finger back and forth. Overshoot or shaking suggests cerebellar involvement. NCBI

5) Rapid alternating movements.
Quickly flipping the hand palm-down/up tests speed and rhythm. Slowness or irregularity points to extrapyramidal or cerebellar dysfunction. NCBI

6) Heel-knee-shin test.
Sliding the heel down the opposite shin checks leg coordination; wobble indicates cerebellar or proprioceptive problems. NCBI

7) Romberg and tandem gait.
Standing with feet together, eyes closed (Romberg) and heel-to-toe walking (tandem) expose balance deficits. NCBI

8) Pull test for postural stability.
A gentle backward tug gauges recovery steps; instability suggests postural reflex impairment. NCBI

C) Laboratory and pathological tests

9) Serum calcium–phosphate–magnesium–PTH–vitamin D.
These core tests look for hypo- or pseudohypoparathyroidism, the most common reversible secondary cause. Correcting abnormalities may prevent progression. NCBI

10) Kidney and liver function tests.
Chronic kidney disease and other systemic illnesses disturb mineral balance and can contribute to calcification. NCBI

11) Thyroid function and broader metabolic panel.
Thyroid disease and general metabolic derangements may coexist and affect symptoms or treatments. NCBI

12) Lactate and pyruvate (± acylcarnitine profile).
These help screen for mitochondrial disorders such as Kearns–Sayre or MELAS when history suggests them. NCBI

13) Infectious work-up (for example HIV, toxoplasma serology; CSF when indicated).
Ordered when infections are possible; congenital and acquired infections can cause intracranial calcifications. NCBI

14) Heavy-metal screen (blood lead, mercury) and toxic exposure history.
Identifies potentially treatable contributors from environment or prior therapies (for example radiation, methotrexate). NCBI

15) Genetic testing panel for PFBC genes.
When secondary causes are excluded, a PFBC gene panel (SLC20A2, PDGFB, PDGFRB, XPR1, MYORG, JAM2, CMPK2, NAA60) can confirm the primary form, guide counseling, and inform family screening. NCBI

D) Electrodiagnostic tests

16) EEG (electroencephalogram).
Looks for seizure activity or diffuse slowing. Useful when spells or events suggest epilepsy or encephalopathy. NCBI

17) Nerve conduction studies and EMG.
Usually normal in PFBC, but considered when weakness, cramps, or neuropathic symptoms need clarification or when another disorder is suspected. NCBI

18) Evoked potentials (for example visual).
Selected when vision or brainstem pathways are questioned; they can document conduction delays in affected tracts. NCBI

E) Imaging tests

19) Non-contrast head CT (key test).
CT is the most sensitive test for brain calcifications. It shows bilateral, symmetric deposits in basal ganglia, thalami, cerebellar dentate nuclei, and subcortical white matter. A standardized Total Calcification Score can quantify burden. PMC+1

20) Brain MRI with susceptibility-weighted imaging (SWI).
MRI confirms anatomy and excludes other lesions. Calcifications can appear as low signal on T2 or blooming on SWI; MRI also assesses white-matter change and brainstem involvement. PMC

21) Functional imaging when needed (FDG-PET or DaTscan/SPECT).
PET can show hypometabolism in affected networks; DaTscan can assess nigrostriatal dopaminergic function if parkinsonism is prominent. These tests are optional and used case-by-case. MD Searchlight

22) Family imaging for screening.
If a pathogenic PFBC variant is found, CT in adult relatives can detect asymptomatic calcification because penetrance rises with

Non-pharmacological treatments (therapies & others)

1. Physiotherapy for balance and gait
   A tailored exercise plan (strength, stretching, balance, cueing) helps reduce falls, maintain walking safety, and improve endurance. Therapists often combine task-specific gait training with home programs and caregiver education. This is central for movement disorders because calcifications can disrupt basal ganglia control of posture and step initiation. NCBI+1

2. Occupational therapy (ADLs & home safety)
   OT teaches energy conservation, safe transfers, bathing/dressing techniques, and home adaptations (grab bars, raised seats, lighting). The goal is independence and injury prevention, especially as gait, rigidity, or tremor progress. NCBI

3. Speech-language therapy (dysarthria/dysphagia)
   SLPs use breath-voice exercises, articulation drills, and safe-swallow strategies (posture, texture modification). Early referral reduces aspiration risk and improves communication confidence. NCBI

4. Cognitive rehabilitation
   Structured memory aids (planners, phone prompts), attention training, and problem-solving practice can offset executive and memory issues sometimes seen in PFBC. Family training helps reinforce strategies at home. NCBI

5. Psychological therapy (CBT and supportive therapy)
   CBT and supportive counseling can reduce anxiety, depression, and adjustment stress related to chronic neurological symptoms and diagnostic uncertainty. Coordination with neurology improves outcomes. NINDS

6. Seizure safety education
   Seizure first-aid, water safety, driving/occupation counseling, medication adherence, and sleep hygiene are critical when epilepsy occurs with BSPDC. Education lowers injury risk and improves control. NCBI

7. Falls-prevention program
   Home hazard review, footwear advice, vision checks, dual-task training, and strength/balance exercises reduce fall frequency—important with gait freezing or dystonia. NCBI

8. Assistive devices
   Appropriate canes/walkers, weighted utensils, lift chairs, and communication aids reduce effort and maintain autonomy while symptoms fluctuate. NCBI

9. Nutritional counseling (individualized)
   Dietitians optimize calorie/protein intake when fatigue, swallowing issues, or mood affect appetite. For secondary calcification due to parathyroid disorders, mineral/vitamin targets are guided by labs. PMC

10. Sleep optimization
    Regular sleep/wake times, light exposure, and treating snoring or REM behavior disorder can reduce daytime sleepiness, which often worsens gait and cognition. NCBI

11. Headache management (non-drug)
    Hydration, trigger diaries, regular meals, and relaxation techniques help if headaches or migraines accompany PFBC. Coordinate with medical therapy as needed. NCBI

12. Caregiver education & support
    Teaching symptom monitoring, safe transfers, and communication approaches reduces caregiver strain and prevents avoidable hospitalizations. NINDS

13. Social services & disability planning
    Navigating benefits, transport assistance, and workplace/school accommodations keeps people active and reduces financial stress. NINDS

14. Genetic counseling (for familial PFBC)
    Explains inheritance, testing options, and family screening. Helps with life planning and reduces uncertainty about risk to relatives. NCBI+1

15. Bone-health & fall-fracture risk review
    Because balance issues increase fracture risk, review vitamin D status, weight-bearing activity, and home hazards to protect bone and prevent injury. NCBI

16. Driving assessment
    For people with cognitive slowing, visual-spatial issues, or seizures, formal testing improves safety and guides restrictions or retraining. NCBI

17. Bladder/bowel routines
    Timed voiding, fiber/hydration plans, and pelvic-floor education can ease constipation or urgency that sometimes accompany neurological disease. NCBI

18. Heat-stress and dehydration avoidance
    Overheating and dehydration worsen fatigue, dizziness, and falls; simple hydration and cooling strategies help daily function. NCBI

19. Vaccination & infection prevention
    Infections can trigger delirium or seizures; keep routine vaccines current and treat fevers promptly in consultation with clinicians. NCBI

20. Community & peer support
    Patient groups and rare-disease communities provide coping tips and reduce isolation; clinicians can connect families to reputable networks. Rare Diseases

Frequently asked questions

1. Is BSPDC/PFBC fatal?
   Most people live many years. Symptoms vary widely—from none to significant disability—so care is individualized and focused on safety and quality of life. NCBI+1

2. Can medicines remove the brain calcifications?
   No. Current drugs control symptoms (seizures, movement, mood). Trials to reverse calcification do not yet exist. SpringerLink

3. How is it diagnosed?
   Non-contrast CT typically shows bilateral calcifications in characteristic deep brain regions. MRI helps rule out other causes. Blood tests screen for secondary causes (calcium, phosphate, PTH, vitamin D). NCBI+1

4. What’s the difference between PFBC and Fahr syndrome?
   PFBC refers to familial/primary forms with known genes; “Fahr disease/syndrome” is an older umbrella term sometimes used for both familial and secondary cases. NCBI+1

5. Do all people with calcifications get symptoms?
   No. Some remain asymptomatic; others develop movement, cognitive, psychiatric, headache, or seizure symptoms. NCBI+1

6. Can children be affected?
   Yes, but onset is often in adulthood; rare childhood forms and gene variants exist. SpringerLink

7. Should my family members be tested?
   In familial cases, genetic counseling helps discuss who to test and when. Imaging of at-risk adults may be considered. NCBI

8. What else can look like PFBC?
   Aging-related calcifications, infections, mitochondrial/metabolic disease, parathyroid disorders, toxins (e.g., CO, manganese) can mimic it—hence the lab/endocrine work-up. NCBI

9. Does vitamin D help or harm?
   Correcting deficiency may help bone health, but excess dosing can cause high calcium and soft-tissue calcification—never megadose without labs and medical supervision. Office of Dietary Supplements

10. Are “vitamin K2 for calcifications” claims true?
    Some heart-artery studies suggest slower vascular calcification progression with K2, but no evidence for brain calcifications in PFBC; talk to your doctor first, especially if on warfarin. Frontiers

11. Can DBS cure the disease?
    No; DBS may help select movement symptoms but does not change calcifications. PMC

12. What imaging follow-up is needed?
    Your team decides based on symptoms; imaging may be repeated if new problems arise or for family studies. NCBI

13. Are headaches part of PFBC?
    Headaches can occur but have many causes; your clinician will rule out other conditions and tailor standard headache therapy. NCBI

14. What about pregnancy?
    Pre-pregnancy medication review is essential (e.g., avoid valproate if possible). Plan care with neurology and obstetrics. FDA Access Data

15. Where can I learn more?
    Reliable sources: GeneReviews, NINDS, Orphanet, NORD patient pages; avoid unproven “decalcifying” treatments online. Rare Diseases+3NCBI+3NINDS+3
