Primary Familial Brain Calcification (PFBC), also known as Fahr's disease, is a rare genetic disorder characterized by the abnormal accumulation of calcium deposits in the brain's blood vessels and certain brain regions. The prevalence of PFBC is estimated to be around 1 in 200,000 individuals worldwide, making it a relatively uncommon condition. PFBC is inherited in an autosomal dominant manner, meaning that an affected individual has a 50% chance of passing the condition on to each of their children.

Prevalence of Primary Familial Brain Calcification: how many people are affected worldwide, differences by sex and region, with sources.
Primary Familial Brain Calcification (PFBC), also known as Fahr's disease, is a rare genetic disorder characterized by the abnormal accumulation of calcium deposits in the brain's blood vessels and certain brain regions. The prevalence of PFBC is estimated to be around 1 in 200,000 individuals worldwide, making it a relatively uncommon condition.
PFBC is inherited in an autosomal dominant manner, meaning that an affected individual has a 50% chance of passing the condition on to each of their children. The symptoms of PFBC can vary widely, but commonly include movement disorders, cognitive impairment, psychiatric symptoms, and seizures.
While the exact cause of PFBC is not fully understood, several genes have been identified as potential contributors to the development of the condition. These genes are involved in regulating the balance of calcium in brain cells.
Diagnosis of PFBC typically involves a combination of clinical evaluation, brain imaging (such as CT scans or MRI), and genetic testing. Unfortunately, there is currently no cure for PFBC, and treatment mainly focuses on managing symptoms and providing supportive care.
It is important for individuals with a family history of PFBC to seek genetic counseling to understand the risks and implications associated with the condition. Ongoing research is being conducted to further understand PFBC and develop potential therapeutic interventions.
