It is a neurological disorder that causes a feeling of discomfort that is only relieved momentarily by moving the legs, due to an uncontrollable compulsion to do so, especially when lying down or sitting, especially in the afternoon or at night.
Women are more likely to suffer from it than men, and it can appear at any time of life and at any age, increasing discomfort over the years, as the quality of sleep and the ease of performing daily activities are affected.
So far, it is unknown what causes restless legs syndrome, also known as Willis-Ekbom disease, but studies indicate that it may be due to a deficiency of dopamine, a neurochemical that helps regulate muscle motility. However, it can also be due to hereditary factors, mainly if the disorder occurs before the age of 40, or as a result of pregnancy due to hormonal imbalances.
Sometimes this syndrome can be accompanied by other conditions, such as:
- Lack of iron.
- Kidney failure.
- Spinal cord injuries.
