Basal Ganglia Calcification: A Rare Neurological Condition

Basal ganglia calcification, also known as Fahr's disease, is a rare neurodegenerative disorder characterized by symmetrical and bilateral calcification of the basal ganglia [3]. This condition occurs when calcium deposits build up in parts of the brain, leading to neurological and neuropsychiatric symptoms [2].

Causes and Prevalence

The exact cause of basal ganglia calcification is unknown, but it is believed to be a genetic disorder with an autosomal dominant inheritance pattern [6]. It is estimated that this condition affects approximately 1% of all CT scans of the brain, depending on the demographics of the scanned population [4].

Symptoms and Clinical Manifestations

The most common presenting symptoms of patients with bilateral basal ganglia calcification are movement abnormalities, such as parkinsonism, ataxia, chorea, tremor, dystonia, athetosis, or seizures [8]. Other clinical findings may include increased tone/spasticity, hyper- or hyporeflexia, abnormal gait or inability to walk, and ataxia [9].

Basal Ganglia Calcification Signs and Symptoms

Basal ganglia calcification, also known as primary familial brain calcification (PFBC), is a progressive disease characterized by the formation of calcium deposits in various parts of the brain. The main signs and symptoms of this condition can vary from person to person but often include:

• Movement Disorders: These are the most common presenting symptoms of basal ganglia calcification, including:
  • Parkinsonism: A group of neurological disorders that cause tremors, stiffness, and movement difficulties [5].
  • Ataxia: Difficulty with coordination and balance [5].
  • Chorea: Involuntary movements, such as jerky or dancing-like movements [5].
  • Tremor: Shaking or trembling of the hands, arms, legs, or other parts of the body [5].
  • Dystonia: Muscle contractions that cause repetitive movements or abnormal postures [5].
  • Athetosis: Involuntary movements, such as writhing or twisting motions [5].
• Psychiatric or Behavioral Problems: Some individuals with basal ganglia calcification may experience:
  • Mood changes: Depression, anxiety, or other emotional disturbances [3].
  • Cognitive impairment: Difficulty with memory, attention, or decision-making [3].
  • Personality changes: Alterations in behavior, such as impulsivity or aggression [3].

It's essential to note that not everyone with basal ganglia calcification will experience all of these symptoms. The severity and progression of the disease can vary significantly from person to person.

Basal ganglia calcification can be diagnosed through various diagnostic tests, which are essential for an accurate diagnosis and treatment plan.

Imaging Tests

• Computed Tomography (CT) scans: CT scans are considered the gold standard for diagnosing basal ganglia calcification. They can show calcifications as hyperdense lesions in the basal ganglia region [8].
• Magnetic Resonance Imaging (MRI): MRI scans can also be used to diagnose basal ganglia calcification, although they may not be as sensitive as CT scans [3]. MRI can show calcifications as areas of low signal intensity in the basal ganglia region.
• X-rays: X-rays might also show if there's any calcium build-up in your brain, but they are less sensitive than CT or MRI scans [1].

Other Tests

• Blood tests: Blood tests may be performed to rule out other conditions that can cause similar symptoms. However, blood tests alone cannot diagnose basal ganglia calcification.
• Genetic testing: Genetic testing may be recommended if there is a family history of the condition or if the diagnosis is unclear.

Important Considerations

• A diagnosis of basal ganglia calcification often requires imaging tests to confirm the presence of calcifications in the basal ganglia region.
• It's essential to consult with a healthcare professional for an accurate diagnosis and treatment plan.

Treatment Options for Basal Ganglia Calcification

Basal ganglia calcification, also known as primary brain calcification, can be a challenging condition to manage due to its progressive nature and lack of a known cure. However, various treatment options are available to alleviate symptoms and improve quality of life.

• Symptom Management: The main goal in treating basal ganglia calcification is symptom management. This may involve the use of medications to control anxiety, depression, obsessive-compulsive disorder (OCD), and dystonia [4].
• Pharmacological Treatment: Studies have shown that pharmacological treatment can be effective in improving symptoms such as anxiety, depression, OCD, and dystonia [8]. Oxybutynin, a medication commonly used to treat overactive bladder, has been found to alleviate these symptoms in patients with basal ganglia calcification.
• Calcium Management: In some cases, abnormal calcium metabolism or parathyroid dysfunction may contribute to the development of basal ganglia calcification. Correcting this imbalance through intravenous calcium gluconate or long-term oral therapy may be necessary [3].
• Long-term Oral Therapy: Long-term oral therapy with calcium supplements may be prescribed to manage calcium levels and prevent further calcification.

It's essential to note that while these treatment options can help alleviate symptoms, there is no specific cure for basal ganglia calcification. A multidisciplinary approach involving a team of healthcare professionals, including neurologists, psychiatrists, and psychologists, may be necessary to provide comprehensive care.

Basal ganglia calcification can be caused by various factors, and it's essential to consider a range of differential diagnoses when evaluating this condition.

• Hypoparathyroidism: This is one of the most common causes of pathological basal ganglia calcification [4]. Hypoparathyroidism is a rare genetic disorder characterized by underactive parathyroid glands, leading to low calcium levels in the blood.
• Pseudohypoparathyroidism: Similar to hypoparathyroidism, pseudohypoparathyroidism is another condition that can cause basal ganglia calcification [4]. It's a genetic disorder affecting the parathyroid hormone receptors, leading to abnormal calcium metabolism.
• Fahr disease (Fahr syndrome): This is a rare neurological disorder characterized by abnormal calcified deposits in the basal ganglia and cerebral cortex [9]. Fahr disease can cause a range of symptoms, including movement disorders, seizures, and cognitive impairment.
• Other systemic or metabolic diseases: Various conditions, such as degenerative diseases, vascular conditions, and endocrine disorders, can affect the basal ganglia and thalamus, leading to calcification [7].
• Idiopathic basal ganglia calcification: In some cases, basal ganglia calcification may occur without a clear underlying cause. This is known as idiopathic basal ganglia calcification [8].

It's essential to consider these differential diagnoses when evaluating patients with basal ganglia calcification, as accurate diagnosis can guide treatment and management decisions.
