what is the difference between multiple sclerosis and amyotrophic lateral sclerosis?

MS is an autoimmune disease that causes the body to attack the myelin sheath that insulates nerve cell fibers in the brain and the spinal cord. In contrast, ALS is a motor neuron disease that mainly affects the actual motor neuron cells in the brain and spinal cord.

When differentiating upper and lower motor neuron disease, remember that upper motor neurons are responsible for motor movement, whereas lower motor neurons prevent excessive muscle movement. Upper motor disorders usually cause spasticity; lower motor disorders usually cause flaccidity.

Lou Gehrig's disease is a disorder that's also called amyotrophic lateral sclerosis (say: ah-my-uh-TRO-fik LA-tuh-rul skluh-RO-sis), or ALS. The official name comes from these Greek words: "a" for without. "myo" for muscle.

Difference is that sensory neurons are carrying info to the CNS while motor neurons are carrying info away.

Another key difference is that multiple sclerosis flares occur over several days, whereas stroke symptoms are sudden and severe and can occur within a few minutes. If your symptoms then appear with full force, it is very likely that you are having a stroke as opposed to a multiple sclerosis flare.

Muscle twitches (or fasciculations) are a common symptom in other neurodegenerative diseases, particularly amyotrophic lateral sclerosis (ALS). It seems that many people living with MS also experience the same twitches from time to time in various parts of the body.

When you have a stroke, a blocked or burst blood vessel cuts off the blood supply to part of your brain. With MS, you have a lifelong disease where your immune system, your body's defense against germs, attacks the nerves in your brain and spinal cord. Two very different conditions, but they can look and feel alike.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system, which leads to the development of focal inflammatory lesions with secondary axonal damage.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting particularly motor neurons for which no cure or effective treatment is available. Although the cause of ALS remains unknown, accumulative evidence suggests an autoimmune mechanism of pathogenesis.

Multiple sclerosis, or MS, is a long-lasting disease that can affect your brain, spinal cord, and the optic nerves in your eyes. It can cause problems with vision, balance, muscle control, and other basic body functions. The effects are often different for everyone who has the disease.

He called it Amyotrophic Lateral Sclerosis (ALS). There are virtually no other neurological conditions in which both these processes occur simultaneously. Nearly 90 percent of patients with MND have the mixed ALS form of the disease, so that the terms MND and ALS are commonly used to mean the same thing.

Sclerosis. Sclerosis in MS is caused by a breakdown in myelin. When demyelination occurs, signals from the brain to other parts of the body are interrupted. In ALS, sclerosis damages the motor neurons, causing the myelin sheath to become harder.

Amyotrophic Lateral Sclerosis (ALS) and other neurodegenerative conditions, including Parkinson's disease (PD), share some common traits. ALS and Parkinson's are both progressive conditions, which means they get worse over time.

Multiple sclerosis, or MS, is a long-lasting disease that can affect your brain, spinal cord, and the optic nerves in your eyes. It can cause problems with vision, balance, muscle control, and other basic body functions.

MS causes gradual destruction of myelin (demyelination) and transection of neuron axons in patches throughout the brain and spinal cord. The name multiple sclerosis refers to the multiple scars (or scleroses) on the myelin sheaths.

The main difference between secondary-progressive MS (SPMS) and primary-progressive MS (PPMS) centers on the presence or absence of relapses. SPMS develops in patients who initially had relapsing-remitting MS (RRMS) as a secondary phase of that disease course.

[Multiple sclerosis: a degenerative disease?] The clinical course results from an interplay between relapses and progression. Relapses are the clinical counterpart of acute focal inflammation of the central nervous system, whereas progression is due to chronic diffuse neurodegeneration.
