Nerve biopsy would show axonal neuropathy, but it is no longer indicated. A muscle biopsy of<unk><unk>  myopathy would show selective loss of thick filaments in muscle, demonstrating the loss of myosin and the presence of muscle cell death (necrosis). When muscles lose stimulation from neurons, they can undergo degeneration. However, when<unk><unk>  myopathy occurs, it is not solely due to loss of innervation of the muscle. With<unk><unk>  myopathy, no other cause of the muscle degeneration can be found. Unlike Guillain Barre Syndrome, another neurological disorder that causes weakness, patients with<unk>  do not have loss of the myelin sheath that normally surrounds neurons (demyelination).
