Primary Familial Brain Calcification: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Primary Familial Brain Calcification?
A neurologist, a doctor who specializes in the brain and nervous system, usually manages this condition. Many patients first see a primary care doctor, who can order initial tests and make a referral. Because the condition is rare, some neurologists work closely with movement disorder specialists or genetics experts.
What it is
Primary familial brain calcification is a rare condition in which calcium deposits build up in parts of the brain that control movement. The word "familial" means it can run in families. The word "primary" means the deposits are the main problem, rather than a side effect of another disease. Many people with these deposits never notice any symptoms. Doctors sometimes call this condition by the older name Fahr's disease.
Symptoms
Symptoms usually start in mid-adulthood, though the age of onset varies from person to person. Some people have no symptoms at all, even when scans show calcium deposits. When symptoms do appear, they often involve movement: muscle stiffness, trembling, slow movement, or trouble with walking and balance. Some people develop slurred speech or involuntary movements.
Causes and who gets it
This condition is caused by changes in certain genes, most often a gene called SLC20A2, and it is usually passed down from a parent. It is very rare, and it affects men and women at similar rates.
How doctors diagnose it
Doctors use a CT scan or MRI to look for calcium deposits in deep areas of the brain. Blood tests can check calcium levels and rule out other causes. Genetic testing and a detailed family history help confirm the diagnosis.
Treatment
There is no treatment that removes the calcium deposits. Care focuses on easing symptoms, such as medicines for movement problems, mood changes, or headaches. Doctors may also suggest speech, physical, or occupational therapy, and they monitor patients over time.
When to see a doctor
See a doctor if you or a family member develops unexplained movement problems, trouble with balance, speech changes, or new thinking or mood difficulties. Early evaluation matters, especially if a relative has this condition.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance for visits. A concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can order brain imaging and blood tests, manage medicines for mood or mild symptoms, and coordinate care among specialists. When symptoms or the diagnosis becomes complex, they will refer the patient to a neurologist.
Common questions
Is primary familial brain calcification the same as normal brain calcification that comes with age?
No. Small calcium deposits can appear in older adults for harmless reasons. But this condition involves deposits in specific deep brain areas and is caused by gene changes.
Will my children get it?
When the condition is passed down in the usual autosomal dominant pattern, each child of an affected parent has a one in two chance of inheriting the changed gene. Genetic counseling can help families understand their specific situation.
Can the calcium deposits be removed?
No treatment is known to remove the deposits once they form. Care focuses on managing symptoms, and what helps one person may not help another.
Can I live a normal life with this condition?
Many people with the gene change never develop symptoms, and others have mild ones. Outcomes differ from person to person, so it is best to discuss your own situation with a doctor.
