How is restless legs syndrome connected to the brain?

Research suggests that the main cause of restless legs syndrome (RLS) is a misuse or lack of iron in the brain, according to the National Institutes of HealthOff Site Icon (NIH).

The brain uses the iron to control some brain activities and to make dopamine, which works in the part of the brain that controls movement, according to the NIH.

There are a variety of conditions that can affect the amount of iron in the brain and how it’s used, according to the NIH, including:

  • Diabetes
  • Iron deficiency
  • Kidney failure
  • Parkinson’s disease
  • Pregnancy
  • Rheumatoid arthritis

Having any of these conditions can increase your risk of also having RLS.

Talk to your doctor for more information about RLS and its connection with the brain.
