    What is the definition of Multiple Sclerosis (MS)?

    Multiple sclerosis is a chronic autoimmune disorder that affects the brain, spinal cord, and nerves, in which the body’s immune system attacks the myelin sheath (tissue that covers nerves) and nerve fibers, causing nerve deterioration, and eventually, permanent nerve damage. These immune system attacks cause patches of scarring on the myelin sheaths, which are called multiple sclerosis. Multiple sclerosis is a progressive disease characterized by periods of relapses during which the disease worsens, usually appears between the ages of 20 and 50, and affects women twice as often as men. Multiple sclerosis is categorized by the following types: Relapsing remitting multiple sclerosis (RRMS) – This type of multiple sclerosis is characterized by several relapses, after which the disease nearly completed remits (recovers) early in the disease, or periods when the disease is stable and not progressing, and includes nearly 85% of multiple sclerosis cases. More than 50% of patients with relapsing remitting multiple sclerosis will develop secondary-progressive multiple sclerosis within 10-to-25 years, although treatments have improved. Secondary-progressive multiple sclerosis (SPMS) – This type of multiple sclerosis starts out as relapsing remitting sclerosis (RRMS), but then demonstrates a progressive worsening that causes disability, and may include remissions, relapses, and periods of stable disease. Primary progressive multiple sclerosis (PPMS) – This type of multiple sclerosis maintains a steady progression of disability, with only occasional periods of stable disease or remissions and accounts for nearly 15% of multiple sclerosis cases. Tumefactive multiple sclerosis – This rare type of multiple sclerosis produces lesions and symptoms that are like those of brain tumors which can develop into relapsing remitting multiple sclerosis (RRMS). Pediatric multiple sclerosis – This rare type of multiple sclerosis affects children under the age of 18.

    When should I see a Multiple Sclerosis (MS) doctor near Fountain Valley, CA?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a Multiple Sclerosis (MS) doctor near Fountain Valley, CA?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How do I find the best Multiple Sclerosis (MS) doctor near Fountain Valley, CA?

    You can find a Multiple Sclerosis (MS) doctor in any of the 10 largest U.S. cities by clicking below:

    Multiple Sclerosis (MS) doctor near Los Angeles, CA

    Multiple Sclerosis (MS) doctor near Boston, MA
    Multiple Sclerosis (MS) doctor near Dallas, TX
    Multiple Sclerosis (MS) doctor near San Jose, CA

    How does MediFind rank Multiple Sclerosis (MS) doctors near Fountain Valley, CA?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Multiple Sclerosis (MS) doctors near Fountain Valley, CA?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a Multiple Sclerosis (MS) doctor near Fountain Valley, CA?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Multiple Sclerosis (MS) doctor search results page. 

    Why is it important to get a second opinion from a different Multiple Sclerosis (MS) doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a Multiple Sclerosis (MS) doctor near Fountain Valley, CA?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Multiple Sclerosis (MS) doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Multiple Sclerosis (MS) doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female Multiple Sclerosis (MS) doctors near Fountain Valley, CA?

    Look for the filter feature on the left side of the Multiple Sclerosis (MS) doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find a Multiple Sclerosis (MS) doctor that offers video calls?

    Look for the filter feature on the left-side of the Multiple Sclerosis (MS) doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
