Amyotrophic Lateral Sclerosis (ALS), commonly known as Lou Gehrig’s Disease, is a progressive neurological disorder that affects nerve cells in the brain and the spinal cord. The disease is characterized by muscle weakness, wasting, and paralysis due to the death of motor neurons in the brain and spinal cord.
The onset of ALS is usually gradual, but it can also be sudden in some cases. Gradual onset of ALS typically begins with muscle weakness in one limb or one part of the body. This is usually followed by muscle twitching and cramping, fatigue, and difficulty speaking, swallowing, and breathing. Gradual onset of ALS is usually more common than the sudden onset.
In contrast, sudden onset of ALS is rare and typically occurs in younger individuals. Symptoms of sudden onset of ALS may include sudden muscle weakness in the arms, legs, or trunk, difficulty speaking, swallowing, or breathing, and rapid progression of the disease.
Overall, ALS can be either sudden or gradual in onset. While gradual onset is more common, sudden onset is possible as well. If you or someone you know is experiencing any of the symptoms of ALS, it is important to seek medical attention right away.
