HTLV-1 associated myelopathy

HTLV-1 associated myelopathy is a progressive inflammatory myelopathy that typically evolves over decades. Typical features include spastic paraparesis typified by early bladder dysfunction, neuritic pains in the low back and legs, and frequent subtle lower motor neuron findings. Brain and cord MRI with serology and PCR will make the diagnosis. There is only symptomatic treatment for inflammation and spasticity, but no specific etiologic treatment.
