Step-by-step explanation:
Diabetes, spinal cord injuries, and multiple sclerosis can cause various neurological effects. Multiple sclerosis (MS) is an autoimmune disease that affects the brain and spinal cord, leading to symptoms such as fatigue, vision problems, weakness in the arms and legs, and numbness or tingling in the extremities. Spinal cord injuries can result in paralysis and loss of sensation or movement in different parts of the body. Diabetes can cause peripheral neuropathy, which is characterized by numbness, tingling, and pain in the extremities.
