HIV-related neuromuscular diseases: nemaline myopathy, amyotrophic lateral sclerosis and bibrachial amyotrophic diplegia

The human immunodeficiency virus (HIV) causes diverse disorders of the brain, spinal cord and peripheral nerves. Rarely, polymyositis and myoglobinuria are seen. Two other neuromuscular syndromes in people with HIV antibodies are nemaline myopathy and bibrachial amyotrophic diplegia, a form of motor neuron disease. The associations between these diseases and the possibility that HIV infection could be a risk factor for either amyotrophic lateral sclerosis (ALS) itself or other motor neuron diseases are investigated.
