Medical Mystery: The Secrets of ALS
Amyotrophic lateral sclerosis remains a scientific field where science faces many unknowns. Experts agree that the disease results from a complex combination of genetic predisposition and environmental factors. Like a sudden weather phenomenon, it can affect people with no family history as well as those with hereditary characteristics.

The Inexorable Process of ALS
This serious neurological disease attacks motor neurons, the vital cells that transmit impulses from the brain to the muscles. When these “biological messengers” die, the muscles, deprived of instructions, gradually lose their tone and atrophy. Gradually, movement, speech, swallowing, and, in advanced stages, breathing are affected.

Early Signs: Symptoms Not to Be Ignored
The first signs are often almost invisible, such as a gradual decline in muscle strength. Atypical muscle fatigue manifests as increasing difficulty with usual activities: walking, climbing stairs, holding objects firmly. What was once automatic suddenly requires increased concentration.

Two Main Forms of the Disease
BAS mainly presents in two forms:

Spinal form: Affects the spinal cord and is more common in men. Muscle spasms, cramps, and constant fatigue are characteristic.

Bulbar form: More common in women, it affects the muscles of the face and throat, causing speech and chewing difficulties. Approximately 30% of patients suffer from this type of disease. Read more on next page
