چکیده
how to cite this article: yıldırım s. inan ar, gül lh, türk börü ü. an acute motor axonal neuropathy (aman) case with motor conductıon blocks in childhood. iran j child neurol. winter 2016; 10(1):65-69. abstract objective characterized with decreased compound muscle action potentials (cmap) and absence of demyelinating findings in electrophysiological studies, is a subtype of guillain-barre syndrome (gbs). a 4 yr-old male patient presented with ascending weakness, dysarthria and dysphagia to i̇stanbul dr. lütfi kırdar kartal training and research hospital neurology outpatient for three days to in 2012. dysphonia, restricted eye movements, flaccid tetraplegia and areflexia were found in neurological examination. there were motor conduction blocks in all peripheral nerves in electrophysiological studies.according to these findings the patient was diagnosed as acute inflammatory demyelinating polyradiculoneuropathy (aidp). reduction of cmap amplitudes in posterior tibial nerve, absence of cmaps in median, ulnar and peroneal nerves and loss of motor conduction blocks were found in following electrophysiological studies. according to these findings, patient was diagnosed as aman. motor conduction blocks may appear in early stage of aman and they disappear in later examinations. that’s why electrophysiological studies must be repeated in patients with gbs.

متن کاملConduction block in acute motor axonal neuropathy.
Guillain-Barré syndrome is divided into two major subtypes, acute inflammatory demyelinating polyneuropathy and acute motor axonal neuropathy. The characteristic electrophysiological features of acute motor axonal neuropathy are reduced amplitude or absence of distal compound muscle action potentials indicating axonal degeneration. In contrast, autopsy study results show early nodal changes in ...

Acute motor axonal neuropathy (AMAN) is a subtype of Guillain–Barré syndrome. Characteristic electrophysiological features of AMAN are reduced amplitude or absence of muscle action potentials. Our patient described progressive weakness in his leg and was not able to independently walk; he had a feeling weakness in his arms within 24 h after the onset of symptoms. He was diagnosed with AMAN acco...
متن کاملPathophysiological heterogeneity of conduction blocks in multifocal motor neuropathy.
The pathophysiological mechanisms responsible for conduction block in multifocal motor neuropathy (MMN) are still unclear. To clarify the physiological abnormalities at the site of the block, we tested the effects induced by polarizing direct currents on motor conduction along forearm nerves in 25 normal nerves (13 subjects), and at the site of conduction block in six nerves (five patients) wit...
