Introduction
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive degeneration of motor neurons. It is a chronic, destructive disease that gradually impairs nerve function. In advanced stages, ALS is extremely difficult to cure. Severe cases may involve the anterior horn cells of the spinal cord, brainstem nuclei, and pyramidal neurons in the cerebral motor cortex. Such involvement can lead to respiratory distress and dysphagia, thereby threatening life. Most patients develop ALS due to genetic factors, immune abnormalities, or viral infections.
In daily life, everyone possesses a certain degree of flexibility. As age increases, flexibility gradually declines, and in some individuals, it may even deteriorate further—manifesting as muscle atrophy. This condition is sometimes referred to as amyotrophic lateral sclerosis (ALS). But what exactly is ALS?
What Is Amyotrophic Lateral Sclerosis (ALS)?
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive degeneration and loss of motor neurons. It is a chronic, destructive disease that gradually impairs nerve function. In advanced stages, the disease becomes extremely difficult to treat. Severe cases may involve the anterior horn cells of the spinal cord, brainstem nuclei, and pyramidal neurons in the cerebral motor cortex. Such involvement can lead to respiratory distress and dysphagia, potentially threatening life. Most patients develop ALS due to genetic or immune abnormalities or viral infections.
Treatment for ALS includes etiological therapy, symptomatic management, and various non-pharmacological interventions. Given that the pathogenic factors underlying ALS are likely multifactorial and interrelated, a comprehensive, multimodal therapeutic approach is essential. Complete halting of disease progression using medications—especially monotherapy—is unrealistic at present, and no drug has yet been proven effective in reversing or reliably controlling disease progression. Current research directions in etiological therapy include targeting excitotoxic amino acid damage, administering neurotrophic factors, antioxidant and free-radical scavenging strategies, anti-apoptotic approaches, gene therapy, and neural stem cell transplantation. Riluzole tablets inhibit glutamate release; treatment for 18 months may modestly slow disease progression, but they do not significantly improve muscle strength or quality of life.
In daily life, maintain healthy lifestyle habits—avoid excessive physical exertion and ensure adequate sleep. We hope this information is helpful to you!
