Amyotrophic Lateral Sclerosis (ALS)
Conditions
Brief summary
ALS is a disorder that weakens motor strength and lung function. Rapid loss of motor neurons in the brain and spinal cord of ALS patients causes the symptoms of increasing weakness and loss of muscle function. While there are drugs to help relieve symptoms of ALS, there is no cure for ALS. Rasagiline is a drug with possible neuroprotective characteristics. Neuroprotective means that the nervous system may be protected against weakening. It is known that rasagiline has possible neuroprotective characteristics and it is approved for use for patients with another disorder, the effectiveness of rasagiline for patients with ALS has not been tested.
Detailed description
The specific aim of this screen study is to determine whether rasagiline is safe in this patient population and if the drug has the potential to slow ALS disease progression
Interventions
rasagiline 2 mg daily for 12 months
