Which are the symptoms of Primary Familial Brain Calcification?

Symptoms of Primary Familial Brain Calcification

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 various areas of the brain. These calcium deposits, also called brain calcifications, can lead to a range of neurological symptoms. The severity and progression of symptoms can vary widely among affected individuals.

Movement Disorders: One of the most common symptoms of PFBC is the presence of movement disorders. These can include tremors, muscle stiffness (rigidity), involuntary muscle contractions (dystonia), and difficulty with coordination and balance. These movement abnormalities can significantly impact a person's ability to perform daily activities.

Cognitive Impairment: PFBC can also cause cognitive impairment, which may manifest as memory problems, difficulties with attention and concentration, and impaired judgment. Some individuals may experience changes in personality, mood swings, and depression. In more advanced stages, dementia-like symptoms may develop, affecting a person's ability to communicate and perform complex tasks.

Seizures: Epileptic seizures are another common symptom of PFBC. Seizures can vary in type and severity, ranging from mild episodes of staring to more severe convulsions. Seizures can further contribute to cognitive decline and impact overall quality of life.

Movement Disorders: In addition to the movement disorders mentioned earlier, PFBC can also cause other motor abnormalities. These may include muscle weakness, difficulty swallowing (dysphagia), and abnormal eye movements (oculomotor abnormalities). These symptoms can significantly affect a person's mobility and ability to perform basic functions.

Psychiatric Symptoms: Some individuals with PFBC may experience psychiatric symptoms, such as hallucinations, delusions, and psychosis. These symptoms can be distressing and may require appropriate management and support.

Other Neurological Symptoms: PFBC can also lead to a variety of other neurological symptoms, including headaches, vertigo, sleep disturbances, and sensory abnormalities. These symptoms can further contribute to the overall burden of the disease.

It is important to note that the symptoms of PFBC can vary widely among affected individuals, even within the same family. The age of symptom onset can also vary, with some individuals experiencing symptoms in childhood or adolescence, while others may not develop symptoms until adulthood.

Given the wide range of symptoms associated with PFBC, a comprehensive evaluation by a neurologist is crucial for accurate diagnosis and appropriate management. Genetic testing can help confirm the diagnosis and identify the specific genetic mutation responsible for the condition.

While there is currently no cure for PFBC, treatment focuses on managing symptoms and improving quality of life. This may involve a combination of medications to control movement disorders, seizures, and psychiatric symptoms. Physical and occupational therapy can also be beneficial in maintaining mobility and independence.
