Another common symptom is a so-called brain fog. In general, a cognitive function is responsible for knowing the world around better and gaining new skills. In the case of patients with dysautonomia, their ability to educate is limited by the poor short-term memory and some other obstacles. They find it hard to concentrate as well as communicate with other people as they are not always sure which word to choose and how to build sentences correctly. As a result, the patients fail to study and work effectively.

People with dysautonomia cannot resist the changes in temperatures. Our limbs serve as the radiators. Along with the rest of the body parts, they make sure the person has a healthy temperature which is 37C. Through remodeling the blood flow to the extremities, our organism regulates the temperature. The autonomous nervous system is the one to manage any fluctuations in temperatures. The result of the disorder is the lower thermal control, which makes the patients suffer from the sudden heat or, vice versa, extreme cold.
