Upper motor neuron lesion with spastic paraparesis is the clinical syndrome. Absence of radicular symptoms, sensory level, sphincter disturbance, back pain, non-progression, HIV-seronegativity and negative family history rule out most compressive, hereditary, infectious and metabolic myelopathies. Upper motor neurons connect the brain to the proper point of the spinal cord, where it can be synapsed and continued by either the local circuit neuron or the lower motor neuron. When the upper motor neuron synapses with the lower motor neuron, the neurotransmitter glutamate is used.

GLASGOW COMA SCALE (GCS) made easy (with ANIMATIONS & MNEMONICS)!! 6.2 Upper Motor Neuron Syndrome. Damage to any part of the motor system hierarchy above the level of alpha motor neurons (not including the side loops) results in a set of symptoms termed the upper motor neuron syndrome. Some of these symptoms are opposite of those of lower motor neuron disorders.

It is agreed that conventional magnetic resonance imaging (MRI) of the brain and spine is one of the core elements in the differential diagnostic work up of patients with clinical signs of motor neuron diseases (MNDs), for example amyotrophic lateral sclerosis (ALS), to exclude MND mimics. Damage to the anterolateral pathways cuase loss of pain and temperature below the level of the lesion, and damage to the anterior horn cells produce lower motor neuron weakness at the level of the lesion. Larger lesions may involve the lateral corticospinal tracts as well. Common causes include trauma, MS, and anterior spinal artery infarct.
