The epidemiology of Lou Gehrigs Disease (ALS): a conspiracy of genes, environment and time.
Multi-dimensional roles of astrocytes in Amyotrophic Lateral Sclerosis (ALS)
Amyotrophic lateral sclerosis (ALS) is a progressive, fatal neurodegenerative disease that affects the respiratory system. Its symptoms include respiratory muscle weakness and respiratory dyspnea. A patient with ALS may experience disturbed sleep, excessive daytime somnolence, morning headaches, and fatigue. Additional symptoms may include anorexia, vivid nightmares, nocturia, tachypnoea, and a weak cough.
Symptoms of ALS
Amyotrophic lateral sclerosis (ALS) symptoms are progressive and can affect many areas of the body. Muscle weakness and atrophy make it difficult for the person to move and speak, and can lead to problems with breathing and walking. Eventually, a person with ALS may not be able to stand or walk at all. Another common symptom of ALS is trouble swallowing. Because the person with ALS cannot chew food, they often lose weight rapidly and become malnourished.
Some ALS symptoms can be managed with medications. These medicines are used to reduce muscle spasms and stiffness. They can also help with respiratory problems, such as pneumonia. Some people with ALS also get a tracheostomy to help them breathe. As the disease progresses, the patient's mobility becomes extremely limited and they will need full time care from an adult. They may also experience constant complaints such as headaches and dizziness.
Diagnosis and Genetic Testing
The diagnosis of ALS is complex, and can involve a variety of tests. As a result, the diagnosis process can be both stressful and confusing. For this reason, it is best to keep a diary of your symptoms, which may help your doctor see a pattern. You should also make sure that your care team communicates with you.
The symptoms of ALS may be hard to differentiate from those of other diseases, such as infectious diseases or neurological conditions. If your symptoms are similar to those of other diseases, your physician may want to run some tests to help rule them out.
Treatment options for ALS
Amyotrophic lateral sclerosis (ALS) treatments include biologics like stem cells and medicines that control the symptoms and slow down the disease's progression. These drugs can also help relieve the pain and depression associated with the disease. Occupational therapy is also available for people affected by the disease. It can help them with daily activities such as getting dressed, brushing their teeth, and moving about. Occupational therapy can also involve using special equipment, such as canes and reach extenders. Patients with ALS may also use wheelchairs to get around. Some may even get a computerized voice synthesizer to help them with speech.
Several companies operate in the amyotrophic lateral sclerosis treatment market. These include major players such as Amylyx Pharmaceuticals Inc., AB Science, Ionis Pharmaceuticals, Biohaven Pharmaceutical, and F.Hoffmann-La Roche AG.
Complications from Neurotoxin exposure
Neurotoxins are substances that can damage the brain and cause neurodegeneration. They have the capacity to target specific neuronal populations and phenotypes, alter intracellular and extracellular mediators, and induce apoptosis. They can also adversely affect astrocytes, which are necessary satellite cells that support neurons.
There are a number of factors that can contribute to ALS, but one major factor that may cause the condition is neurotoxin exposure. Many people develop ALS after being exposed to a neurotoxin, and neurotoxins have the potential to cause symptoms and even death. A recent study has identified a neurotoxin called BMAA as a potential cause of ALS in humans.
The etiology of the disease is not yet known, but studies in vitro have revealed several important mechanisms. For example, glutamate causes a gliosys response, which releases growth factors for repair. Moreover, glutamate opens ca++ channels and inhibits ATP synthesis. Inflammation, genetic muations (SOD1 Variant) and neuroimmunological events are thought to be involved in ALS and suggest potential therapeutics.
