The overall clinical presentation was consistent with motor neurone disease. Cerebrospinal fluid analysis revealed mild pleocytosis and increased protein concentration. [ncbi.nlm.nih.gov]

• Muscular Atrophy

  The condition has been called progressive muscular atrophy (PMA), spinal muscular atrophy (SMA), Aran–Duchenne disease, Duchenne–Aran disease, Aran–Duchenne muscular atrophy, and Duchenne–Aran muscular atrophy. [en.wikipedia.org]

• Muscle Twitch

  This then leads to fasciculations (muscle twitches), progressively worsening muscle weakness, and a loss of muscle mass and weight. The facts: PMA affects about five to seven percent of people with MND. [mndcentre.org.uk]

  Medications may be prescribed to control involuntary muscle twitching, muscle cramps and excess saliva. However, treatment essentially focuses on retaining function and quality of life, and providing comfort. [southerncross.co.nz]

  Muscles twitch (called fasciculations). Muscle tone typically increases, and muscles tend to become stiff and tight, leading to muscle spasms (called spasticity). Movements are stiff and clumsy. [merckmanuals.com]

  A single motor neuron may innervate many muscle fibres and a fibre can undergo many action potentials in the time taken for a single muscle twitch. [wikivisually.com]

After the diagnosis is made the doctor will discus treatment options with the patient. The actual treatment that is effective in stopping the deterioration of the nerve is still unknown. [ic.steadyhealth.com]

The distinction is important because PMA is associated with a better prognosis than classic ALS. [en.wikipedia.org]
