The Acute Inflammatory Demyelinating Polyneuropathy
The Acute Inflammatory Demyelinating Polyneuropathy The Acute Inflammatory Demyelinating Polyneuropathy (AIDP) is the most common form of Guillain-Barré Syndrome (GBS), a rare but potentially life-threatening neurological disorder. It involves the immune system mistakenly attacking the peripheral nerves, which are responsible for transmitting signals between the brain and spinal cord to the rest of the body. The hallmark of AIDP is rapid-onset muscle weakness and, in severe cases, paralysis that can escalate over days or weeks.
The Acute Inflammatory Demyelinating Polyneuropathy Typically, the symptoms of AIDP begin with tingling sensations or numbness in the extremities, particularly the feet and legs. This sensory disturbance often progresses proximally, affecting the thighs, hips, and eventually the upper limbs and face. As the immune response intensifies, patients may experience muscle weakness, difficulty walking, and diminished reflexes. In some cases, the paralysis can ascend quickly, affecting the respiratory muscles and necessitating ventilatory support. The progression varies among individuals, but prompt diagnosis and intervention are crucial to prevent severe complications.
The pathophysiology of AIDP involves an autoimmune reaction often triggered by infections, particularly those caused by Campylobacter jejuni, Cytomegalovirus, Epstein-Barr virus, or Mycoplasma pneumoniae. These infectious agents are believed to induce molecular mimicry, where immune responses directed against pathogen components cross-react with the myelin sheath—the protective covering surrounding peripheral nerve fibers. This immune attack damages the myelin, leading to demyelination, which disrupts nerve conduction and results in the characteristic weakness and sensory deficits.
The Acute Inflammatory Demyelinating Polyneuropathy Diagnosis of AIDP hinges on clinical presentation, supported by electrophysiological studies such as nerve conduction velocity tests, which demonstrate slowed nerve conduction indicative of demyelination. Cerebrospi
nal fluid analysis often reveals elevated protein levels with normal cell counts—a phenomenon known as albuminocytological dissociation. These findings, combined with the rapid progression of symptoms and exclusion of other causes, confirm the diagnosis.
The Acute Inflammatory Demyelinating Polyneuropathy Treatment strategies focus on modulating the immune response and supporting recovery. Intravenous immunoglobulin (IVIG) and plasma exchange (plasmapheresis) are the mainstays of therapy, both shown to accelerate recovery and reduce the severity of symptoms. Supportive care, including physiotherapy, respiratory management, and pain control, plays a vital role in patient recovery. Most individuals experience significant improvement over weeks to months, although some may have residual weakness or neurological deficits.
The prognosis of AIDP varies depending on the severity of initial symptoms and the speed of intervention. While many patients recover almost completely, others may experience persistent impairments. Early diagnosis and treatment are essential to prevent complications, including respiratory failure and autonomic dysfunction, which can be life-threatening.

Understanding AIDP underscores the importance of recognizing early signs of peripheral nerve involvement and seeking prompt medical attention. Advances in immunotherapy and supportive care continue to improve outcomes, transforming a once potentially fatal condition into a manageable illness with a good chance for full recovery.
