To ascertain whether or not misfolded SOD1 is a common pathological feature in non- SOD1 ALS, we performed a blinded histological and biochemical analysis of post mortem brain and spinal cord tissues from 19 sporadic ALS, compared with a SOD1 A4V patient as well as Alzheimer's disease (AD) and non-neurological controls.

When there is preservation of sensation and/or motor activity below the neurological level of insult that includes the lowest sacral segments (S4-S5), the injury is termed incomplete. (dovepress.com)
A thorough neurological examination is fundamental to evaluate the spinal cord function and provide the client with a reasonable prognosis. (vin.com)
As a next step, scientists will use the devices to better understand neurological disease, test drugs and therapies that have clinical potential, and compare different patient-derived cell models. (frogheart.ca)

These findings suggested that the DRGs and the dorsal horn of the spinal cord are important targets for electroacupuncture at ST25 to reduce visceral hypersensitivity in IBS rats. (iasp-pain.org)

Excitotoxic mechanisms kill neurons and oligodendrocytes, leading to demyelination. (medscape.com)

Bexarotene (Bxt) is a retinoid-X receptor agonist used in the treatment of cutaneous lymphoma with a favorable safety profile whose effects have been recently investigated in other neurodegenerative diseases. (frontiersin.org)

Following IV placement, anesthesia, hand bagging to get the radiographs and do a myelogram that should a ruptured C4-5 space and cord compression. (dvm360.com)
When the spinal cord flattens due to compression, pathological changes occur in the gray matter. (epainassist.com)
For the diagnosis of cervical spondylosis, it is important to diagnose a high-level disorder based on the symptom of the spinal cord and/or radiculopathy and to judge whether or not the high level generally matches the spinal cord compression seen on the image. (epainassist.com)

When the lowest sacral levels are without sensory and motor activity, the injury is termed complete. (dovepress.com)
Spinal Cord Injury is severe damage to the human spinal cord. (cellebrationlifesciences.com)
The damage to the spinal cord begins at the moment of injury when displaced bone fragments, disc material, or ligaments bruise or tear into spinal cord tissue. (braininjurysupport.org)
A spinal cord injury is a medical emergency and immediate treatment has the potential to reduce long-term effects. (braininjurysupport.org)
Any damage to the spinal cord is a very complex injury. (braininjurysupport.org)
People who are injured are often confused when trying to understand what it means to be a person with a spinal cord injury (SCI). (braininjurysupport.org)
The following is a brief summary of the changes that take place after a spinal cord injury. (braininjurysupport.org)
It tells how the spinal cord works and what some of the realistic expectations are for what a person should eventually be able to do following a spinal cord injury. (braininjurysupport.org)
Considerable differences exist in terms of clinical complications after traumatic and nontraumatic spinal cord injury (SCI). (medscape.com)

A second period of EV-D68 circulation, again associated with severe respiratory disease, was described during late summer and fall of 2016, although 2 studies suggest lower levels of circulation during that period than in 2014 ( 8 , 9 ). (cdc.gov)
The ventral (anterior) horns of the grey matter contain lower motor neurons. (emcrit.org)
