Symptoms Of Upper Motor Neuron Lesion
What are the symptoms and signs of the upper motor neuron lesion (cortex, internal capsule, brainstem, spinal cord) ?
Neurologist: The physical exam findings will be more difficult to see, but a neurologist will be able to examine the patient and might elect to do testing such as an EMG which tests the conduction of the nerves. ...Read more

Higher brain centers: Babies normally have babinski responses but lose it as they mature. The response remains deep in the brain and spinal cord but is suppressed by the higher brain centers. 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
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
Weakness: Motor neuron diseases affect the nerves that send the impulse to muscles to initiate movement. Examples of motor neuron diseases include lou gerig's disease(als) and spinal muscular atrophy. Symptoms may include limb weakness, difficulty swallowing, and difficulty breathing. Some types may also affect eye movement and facial expression. ...Read moreSee 1 more doctor answer
Clinical is the best: You've just stated a few hundred different disease processes that involve "UMN disorders." Which one did you have in mind? The best way to a diagnosis is a well trained neurologist who likes to examine their patients, judiciously use tests to help support their clinical thinking or help reorient them if necessary and not make snap decisions. Do you know anybody like that? That's who needs to see U ...Read more
What happens if the upper motor neurons are damaged wouldn't that result in lower motor neuron weakness?
ALS: Yes, in some individuals there does seem to be a prevalence for one versus the other. At least at the beginning of the disease. As it progresses both upper and lower are progressively destroyed. Within ALS I wouldn't call it a rare finding. Its more related to the precision of the diagnostic findings by individual neurologists and overall timing. ...Read moreSee 1 more doctor answer
