How can I find out if I have ALS?
Answer:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease, is a progressive nervous system disorder that affects nerve cells in the brain and the spinal cord. If you are concerned that you may have ALS, it is important that you speak with a doctor for a complete medical evaluation. This article will provide information on the various tests and procedures used to diagnose ALS.
The first step in diagnosing ALS is to take a complete medical history and perform a physical exam. Your doctor will want to know your complete medical history and any prior neurological issues, as well as family history of neurological disorders. They may also ask if you are experiencing any of the common symptoms of ALS, such as muscle weakness or twitching, cramping, difficulty speaking, difficulty swallowing, or changes in your handwriting.
Once your medical history and physical exam are complete, your doctor may order a number of tests to help confirm or rule out ALS. Some of these tests may include blood tests, an electromyogram (EMG), or a nerve conduction velocity (NCV) test. Blood tests can help rule out other potential causes of symptoms, such as thyroid disease or vitamin deficiency. An EMG test measures the electrical activity in your muscles, while an NCV test measures the speed of electrical signals traveling through your nerves.
Imaging tests, such as an MRI or CT scan, may be ordered to look for any abnormalities in the brain or spine. These scans can help identify any areas where the nerve cells have been damaged or have died. Your doctor may also order a lumbar puncture, or spinal tap, to obtain a sample of cerebrospinal fluid to test for any inflammatory markers.
Once all testing has been completed, your doctor will be able to make a diagnosis. If your test results and symptoms suggest ALS, your doctor may refer you to a neurologist for further evaluation and treatment recommendations.
It is important to remember that there is no single test that can diagnose ALS definitively. However, with proper testing and evaluation, your doctor will be able to determine if your symptoms are indicative of ALS or another condition. If you are concerned that you may have ALS, it is important to speak to your doctor to discuss the best course of action.
