What is Multifocal Motor Neuropathy (MMN)?

Multifocal motor neuropathy in Canada (MMN) is a disease that affects your body's motor nerves. Those are the nerves that control your muscles.

The condition makes it hard for them to send the electrical signals that move your body, which makes your hands and arms feel weak.

MMN in Canada is not life-threatening, and, in most cases, treatments can make the muscles stronger.

MMN (Multifocal Motor Neuropathy) is a finite disorder in which important fields of various motor nerves are attacked by one’s own immune system.

MMN is slowly progressive, appear in an asymmetrical weakness of a patient’s limbs.

Patients generally develop weakness in their hand(s), resulting in dropping of objects or consistently inability to turn a key in a lock.

The weakness associated with MMN can be recognized as fitting a specific nerve territory.

There is essentially no numbness, tingling, or pain. Patients with MMN can have other manifestation counting blink or small random dimpling of the muscle under the skin which neurologists call fasciculation.

MMN has many features similar to CIDP in that its onset is progressive over time, causing increased disability that reflects the greater number of nerve sites involved.

For all that, dissimilar CIDP, MMN is asymmetric and suggest the right and left the side of the body differently. Unlike other forms of chronic nerve inflammation, it is thought to never remit.

However appropriate treatment that is FDA approved does limit progression and improves function.

What causes Multifocal Motor Neuropathy?

No one knows what causes Multifocal Motor Neuropathy (MMN) in Canada. Scientists do know it’s an autoimmune disease, meaning your immune system mistakenly attacks your nerve cells as if they were invaders.

Researchers are studying the disease to try to find out why it happens.

What are the symptoms of Multifocal Motor Neuropathy?

If you have MMN, you’ll most likely notice the first manifestation:

1. In your hands and lower arms.
2. Your tissue may feel feeble and cramp up or twitch in a way you can’t control. It may start inexact parts of the arm or hand, like the wrist or finger.
3. Usually, the symptoms are more severe on one side of your body. The disease may eventually affect your legs.
4. MMN isn’t difficult, and you’ll still be able to feel with your hands and arms because your sensory nerves are not concerned.
