Upper Motor Neuron vs. Lower Motor Neuron Disease. It is important for the practicing clinician to make the distinction between the term motor neuron disease (MND) and motor neuron diseases (MNDs). The intention of the first term, coined by Brain in 1969, is to refer to a specific disorder of both upper and lower motor neurons otherwise known as amyotrophic lateral sclerosis (ALS). The second term refers to the broader family of disorders that, 1. Lower motor neuron patterns of weakness Patients may have lower motor neuron (LMN) signs (more focal weakness and prominent muscle atrophy, decreased muscle stretch reflexes and tone, and fasciculations) from lesions occurring anywhere along the length of spinal cord or brain stem lower motor neurons..
