Doctor's Notes on Multiple Sclerosis Treatment Drugs and Side Effects

Multiple sclerosis is a chronic typically progressive disease due to damage of the myelin sheaths of nerve cells in the brain and spinal cord. Myelin sheath damage in multiple sclerosis may vary in people, but usually produce one or more of the following signs and symptoms: weakness and fatigue, vision problems, walking and balance problems, libido problems, pain, bowel and bladder problems cognition problems and various emotional changes like mood swings, irritability, uncontrollable crying or laughing.

The intermediate cause of multiple sclerosis is that myelin sheaths are disrupted or destroyed leaving nerves unprotected. Obtaining and/or sending nerve pulses inappropriately or not getting or sending any is the result. Over time, scar formation (sclerosis) occurs that further disrupts nerve signals. The primary or underling cause of myelin sheath damage and destruction is likely the body’s immune system that inappropriately attack the sheaths (likely the protein[s] in myelin).
