A regulatory framework Although common in other process manufacturing industries (e.g., food and chemicals), continuous processing is at a nascent stage in the pharmaceutical industry, where batch manufacturing is the prevailing mode.
When the motor neurons in the brainstem are affected (bulbar ALS), the muscles used in speech and swallowing are impaired. ALS only affects muscles that are moved voluntarily (such as those in the mouth or arm) and does not impact those muscles involved in involuntary movements, such as digestion.
Amyotrophic lateral sclerosis (ALS) is a progressive disease that affects motor neurons, which are specialized nerve cells that control muscle movement. These nerve cells are found in the spinal cord and the brain. In ALS, motor neurons die (atrophy) over time, leading to muscle weakness, a loss of muscle mass, and an inability to control movement.
