How Does The Upper Notor Neuron Lesion Cause The Babinski Sign

If the higher brain centers become damaged, these primitive responses return because they are no longer being suppressed. Hope this helps to simplify the prior excellent answer. ...Read moreSee 1 more doctor answer

Permanent or temporary? What is specific pathology? There are all kinds of qualifiers. ...Read more
Lesion Localization: The upper motor neurons also called “Cortical Motor Neurons” are located in the motor cortex of the brain. The the spinal motor neurons are the lower motor neurons. Signs of UMN is a stiffness and resistance to movement. Signs of LMN damage include weakness, muscle atrophy. Hope it helps. ...Read more
Antipsychotics: Demyelinating disease is generally autoimmune in nature -- different from the effects of antipsychotic medications.
