Understanding ALS

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons. It leads to muscle weakness, paralysis, and ultimately respiratory failure.

The Science of ALS

ALS targets motor neurons in the brain and spinal cord. These neurons control voluntary muscle movement, enabling actions like walking, talking, and breathing.

As ALS progresses, motor neurons degenerate and die. This causes muscles to weaken, twitch, and waste away. The disease typically begins in the limbs, trunk, or bulbar region.

Genetic mutations play a role in some ALS cases. SOD1, C9orf72, and TDP-43 are among the genes linked to the disease. Environmental factors may also contribute, but their exact role remains unclear.

Research has identified abnormal protein accumulation in neurons as a key factor. These protein clumps may interfere with normal cellular functions, leading to neuron death.

Current ALS Treatments

There is no cure for ALS, but treatments aim to slow progression and manage symptoms. FDA-approved medications include riluzole and edaravone.

Riluzole may extend survival by a few months. It works by reducing glutamate release, which can be toxic to neurons. Edaravone acts as an antioxidant, potentially slowing functional decline.

Multidisciplinary care is crucial for ALS patients. This includes:

• Physical therapy to maintain muscle strength

• Occupational therapy for daily living assistance

• Speech therapy for communication aids

• Nutritional support to address swallowing difficulties

• Respiratory support as breathing becomes impaired

Assistive devices like wheelchairs and voice synthesizers help maintain quality of life. Researchers continue to explore new treatments, including stem cell therapies and gene-targeted approaches.
