Is spasticity a symptom of ALS?

ALS can affect people of any age, though it usually strikes in late middle age. ALS typically announces itself with persistent weakness or spasticity in an arm or leg (80 percent of all cases), causing difficulty using the affected limb.

What does ALS spasticity feel like?

What are the symptoms? The onset of ALS may be so subtle that the symptoms are overlooked. The earliest symptoms may include fasciculations (muscle twitches), cramps, tight and stiff muscles (spasticity), muscle weakness affecting a hand, arm, leg, or foot, slurred and nasal speech, or difficulty chewing or swallowing.

What is ALS spasticity?

Muscle and Tone (Spasticity) Effects. Tone (spasticity) is present in some people with ALS. It causes a tightening of muscles and a stiffening of the body including the arms, legs, back, abdomen, or neck.

Does ALS lead to spastic paralysis?

The disease is caused by degeneration of upper motor neurons in the motor cortex and of lower motor neurons in the brainstem and spinal cord. This combined loss of function causes spastic paralysis, flaccid muscle weakness, wasting, and fasciculations.

What does ALS feel like in the legs?

With ALS, you may first have weakness in a limb that occurs over a few days or, more often, a few weeks. Then a few weeks or months later, weakness develops in another limb. For other people, the first sign of a problem may be slurred speech or trouble swallowing. As ALS progresses, more and more symptoms are noticed.

How does ALS feel in the legs?

Weakness in your legs, feet or ankles. Hand weakness or clumsiness. Slurred speech or trouble swallowing. Muscle cramps and twitching in your arms, shoulders and tongue.

What muscles are affected first with ALS?

When ALS begins in the bulbar motor neurons, localized in the brainstem, the muscles used for swallowing and speaking are affected first. Rarely, symptoms begin in the respiratory muscles. As ALS progresses, symptoms become more widespread, and some muscles become paralyzed while others are weakened or unaffected.

What does the beginning of ALS feel like?

Early symptoms of ALS are usually characterized by muscle weakness, tightness (spasticity), cramping, or twitching (fasciculations). This stage is also associated with muscle loss or atrophy.
