Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to a neurologist (brain and nerve doctor).

Living with it

  • Keep a simple diary of symptoms, triggers, and medicines to bring to visits.
  • Bring a list of your medicines and questions to each visit.
  • Make your home safe from falls: good lighting, no loose rugs, grab bars.
  • Ask your doctor whether it's safe to drive.
  • Long-term illness can affect mood. Tell your doctor if you feel down or anxious.

Support groups and helplines

Back to school, work, or sports

  • Many people keep working in the early stages, with changes to their tasks.
  • Plan ahead for work, money, and legal choices while you can.

Pregnancy and breastfeeding

  • If you're pregnant or planning to be, tell your prenatal provider about this condition.
  • Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
  • Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
  • Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

For caregivers

  • Set up a pill organizer and a simple daily routine.
  • Make the home safe from falls.
  • Go to visits with them and write down what the doctor says.
  • Take breaks and ask for help. Caregivers need care too.

Treatment keeps many people active for years.
