Progressive muscular atrophy (PMA), also called Duchenne–Aran disease and Duchenne–Aran muscular atrophy, is a disorder characterised by the degeneration of lower motor neurons, resulting in generalised, progressive loss of muscle function.
Symptoms of motor neuron diseases can be first seen at birth or can come on slowly later in life. Most of these diseases worsen over time; while some, such as ALS, shorten one's life expectancy, others do not. [2] Currently, there are no approved treatments for the majority of motor neuron disorders, and care is mostly symptomatic. [2]
The average lifespan after the onset of symptoms in patients with MSA is 6–10 years. [4] Approximately 60% of patients require a wheelchair within five years of onset of the motor symptoms, and few patients survive beyond 12 years. [4] The disease progresses without remission at a variable rate.
Duchenne muscular dystrophy is a rare progressive disease which eventually affects all voluntary muscles and involves the heart and breathing muscles in later stages. Life expectancy is estimated to be around 25–26, [18] [59] but this varies. People born with Duchenne muscular dystrophy after 1990 have a median life expectancy of ...
Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken.The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.
The most common symptoms include: [5] [6] [7] Chronic cough; Shortness of breath or dyspnea when exercising or exerting one's self; Wheezing (less frequent) Hemoptysis (Infrequent) Symptoms may be present for many years prior to diagnosis and are often ascribed to other lung conditions.
Distal spinal muscular atrophy type 1 (DSMA1), also known as spinal muscular atrophy with respiratory distress type 1 (SMARD1), is a rare neuromuscular disorder involving death of motor neurons in the spinal cord which leads to a generalised progressive atrophy of body muscles.
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present.
