Encephalitis Periaxialis Concentrica (EPC) is a rare neurological condition that affects the brain’s white matter. In this article, we’ll break down the types, causes, symptoms, diagnostic tests, treatments, and drugs associated with EPC in easy-to-understand language.
Balo Disease is a rare and progressive variant of multiple sclerosis. It usually first appears in adulthood, but childhood cases have also been reported. While multiple sclerosis typically is a disease that waxes and wanes, Balo Disease is different in that it tends to be rapidly progressive. Symptoms may include headache, seizures, gradual paralysis, involuntary muscle spasms, and cognitive loss. The alternative names for Balo Disease, concentric sclerosis or Balo concentric sclerosis, refer to the fact that Balo Disease is characterized by bands of intact myelin (the sheath of fatty substances surrounding nerve fibers), alternating with rings of loss of myelin (demyelination), in various parts of the brain and brain stem. The symptoms of Balo Disease vary, according to the areas of the brain that are affected. Symptoms may progress rapidly over several weeks or more slowly over two to three years.
Types of EPC:
- Primary EPC: This is the most common type and occurs without any known underlying cause.
- Secondary EPC: This type develops as a result of another condition or infection.
Causes of EPC:
The cause of MS and its variants remains unknown. However, some studies indicate that autoimmune factors may play a role in the development of Balo Disease. Autoimmune disorders are caused when the body’s natural defenses against “foreign” or invading organisms (e.g., antibodies) begin to attack healthy tissue for unknown reasons.
- Viral Infections: Certain viruses can trigger EPC, such as herpes simplex.
- Autoimmune Disorders: When the immune system mistakenly attacks the brain’s white matter, EPC can develop.
- Genetics: In some cases, EPC can be linked to genetic factors.
- Toxic Exposure: Exposure to certain toxins can lead to EPC.
- Metabolic Disorders: Conditions that affect metabolism, like Wilson’s disease, can be a cause.
Symptoms of EPC:
Most cases are characterized by the gradual onset of symptoms that might be found in the more common type of MS, including muscle spasms and paralysis. Other neurological symptoms develop depending on the areas of the brain that are affected and may include intellectual impairment and/or physiological abnormalities. However, in its most serious form, Balo Disease may also suggest the presence of an infectious disease, starting with a high fever and painful headaches.
- Headaches: Frequent and severe headaches are a common symptom.
- Weakness: Muscle weakness or paralysis can occur.
- Coordination Problems: Difficulty in coordinating movements.
- Vision Changes: Blurred or double vision.
- Cognitive Issues: Memory problems and confusion.
- Seizures: Some individuals may experience seizures.
- Behavioral Changes: Mood swings or personality changes.
- Speech Difficulties: Trouble speaking or understanding speech.
- Fatigue: Excessive tiredness.
- Loss of Sensation: Numbness or tingling in the limbs.
Diagnostic Tests for EPC:
- MRI (Magnetic Resonance Imaging): This scan creates detailed images of the brain to identify abnormalities.
- CT (Computed Tomography) Scan: It helps visualize the brain’s structure and any possible damage.
- Spinal Tap (Lumbar Puncture): A sample of cerebrospinal fluid is taken and analyzed for signs of inflammation.
- Blood Tests: These can reveal infection markers or metabolic issues.
- Electroencephalogram (EEG): Measures brain activity and can detect abnormal patterns.
- Biopsy: In some cases, a small brain tissue sample may be taken for examination.
- Nerve Conduction Studies: These tests assess nerve function.
Treatments for EPC:
- Medications: Corticosteroids may be prescribed to reduce inflammation and control the immune response.
- Immunosuppressive Drugs: These drugs can help calm the immune system’s overactivity.
- Antiviral Medications: If a viral infection is the cause, antiviral drugs may be used.
- Plasma Exchange (Plasmapheresis): In severe cases, this procedure removes harmful antibodies from the blood.
- Physical Therapy: Helps improve muscle strength and coordination.
- Occupational Therapy: Focuses on enhancing daily life skills.
- Speech Therapy: Assists with communication difficulties.
- Seizure Medications: If seizures occur, specific medications can be prescribed.
- Pain Management: Medications or therapies to manage headaches and discomfort.
- Supportive Care: Adequate rest, nutrition, and hydration are essential during recovery.
Drugs Used in EPC Treatment:
- Prednisone: A corticosteroid that reduces inflammation.
- Methotrexate: An immunosuppressive drug.
- Acyclovir: An antiviral medication for viral-induced EPC.
- Intravenous Immunoglobulin (IVIG): Provides immune system support.
- Diazepam: Helps manage seizures.
- Gabapentin: Used for neuropathic pain.
- Physical Therapy Drugs: Medications to ease muscle spasms.
- Antidepressants: May be prescribed for mood changes.
- Anticonvulsants: Medications to control seizures.
- Pain Relievers: Over-the-counter or prescription drugs for headache relief.
Encephalitis Periaxialis Concentrica is a complex condition that affects the brain’s white matter, leading to various neurological symptoms. It can be categorized into primary and secondary types. Primary EPC occurs without any known cause, while secondary EPC is linked to other conditions or infections.
The causes of EPC can vary. It may develop due to viral infections like herpes simplex, autoimmune disorders where the immune system attacks the brain, genetic factors, exposure to toxins, or metabolic disorders like Wilson’s disease.
