Attention Deficit Hyperactivity Disorder
Attention deficit hyperactivity disorder is a condition associated with hyperactivity. According to the National Institute of Mental Health, which is a division of the National Institutes of Health, ADHD is a common childhood disorder and can last through the teenage years and into adulthood. ADHD is characterized by an inability to stay focused and pay attention, difficulty regulating behavior and hyperactive or overactive behavior. The NIMH states that ADHD has three principle subtypes: predominantly hyperactive-impulsive, predominantly inattentive, and combined hyperactive-impulsive and inattentive. Although experts are not sure what causes ADHD, the condition is believed to be multifactorial or caused by many different factors, with a person's genes playing the most significant role. Other possible causes of ADHD include environmental factors such as cigarette smoking, brain injuries, nutrition and a child's social environment.
Restless Leg Syndrome

The National Institute of Neurological Disorders and Stroke states that restless leg syndrome is a neurological disorder in which a person experiences an uncontrollable urge to move his legs when at rest. Patients with restless leg syndrome often describe the unwanted leg sensations as burning, creeping or tugging. Restless leg syndrome-related symptoms are often felt most acutely when lying down and attempting to relax, which means that most people experience the leg sensations at night while lying in bed.
