Motor Neuron Types: Progressive muscular atrophy (PMA), also known as Duchenne-Aran muscular atrophy, is a rare sub type of motor neuron disease.
Progressive muscular atrophy only affects the lower motor neurons.
It is a sibling condition to amyotrophic lateral sclerosis (ALS), which affects both the upper and lower motor neurons. The distinction is important because PMA is associated with a better prognosis than classic ALS. Symptoms of progressive muscular atrophy include: Atrophy Muscle weakness Lack of reflexes Lack of spasticity Symptoms can be limited to the arms, legs, or both. #humsaathhai #DBLsocialwelfarefoundation #PhysiodeptGHMC
