FEATURES OF ELECTROPHYSIOLOGICAL METHODS FOR GUILLAIN–BARRÉ SYNDROME

2/3 of patients have symptoms of acute respiratory viral infections or gastrointestinal disorders. The first symptoms of GBS are paresthesia of the toes, followed by progressive weakness of the muscles of the lower extremities and impaired walking. The disease progresses for several hours or days, weakness of the upper limbs and cranial nerve palsy develop. Paralysis is usually symmetrical and, of course, peripheral in nature. Pain may be the initial complaint in half of patients, which makes diagnosis difficult. Ataxia and pain are more common in children than in adults. Urinary retention is observed in 10-15% of patients. Damage to the autonomic nerves is manifested by dizziness, hypertension, excessive sweating and tachycardia.
