Myelopathy in AIDS. A clinical and electrophysiological study of 23 Danish patients.
In a cross-sectional population study of Danish patients with AIDS 16 of 23 had clinical signs of neurological disease with muscle weakness or ataxia of the lower limbs as the dominant manifestation. Tibial and median nerve conduction was mildly slowed in a few patients and 15 had widening of cerebral ventricles at CT. However, all had prolonged latency of cortical evoked response following tibial nerve stimulation mainly due to slowing through the spinal cord. The prolongation of the latency of the evoked cortical responses was most pronounced in patients with lower limb ataxia and/or paresis. It is concluded that affection of the long tracts of the spinal cord are closely associated with the human immunodeficiency virus infection.
