Asthma is a chronic lung disease where the tissue and airways of the lungs become extremely sensitive to certain substances. When these substances are breathed in, the lungs become inflamed. The muscles around the airways tighten and squeeze the lungs, and passages within the lungs swell and tighten. The airways themselves produce mucus, which further clogs the tightened, swollen airways. A person having an asthma attack finds it very difficult to breathe, and a severe attack can even be fatal.

Asthma affects people of all ages, but people with asthma are most often diagnosed as children. Symptoms can include wheezing, a tight feeling in the chest, shortness of breath, and coughing. Some people have mild symptoms all the time, and some people have no symptoms at all, but everyone with asthma is susceptible to occasional severe attacks or flare-ups of symptoms when they are exposed to triggers. Triggers vary widely but can include:

• Allergens (dust mites, pet fur, mold, pollen, grass)
• Irritants (smoke, pollution, dust, chemicals)
• Viral infections
• Physical activity, especially outdoors
• Certain medications or chemicals in foods (aspirin, sulfites)

Attention Deficit Hyperactivity Disorder, or ADHD, is one of the most common disorders diagnosed in children. Nine percent of children in the USA have been diagnosed with ADHD. Symptoms, which include hyperactivity and difficulty maintaining focus or paying attention, can last into adulthood for some patients. Boys are four times as likely to be diagnosed as girls, although experts don't know why this is.

There are three main types of ADHD:

• Predominantly hyperactive-impulsive types show symptoms such as constant fidgeting, talking non-stop, touching everything, having trouble sitting still and waiting their turn, and interrupting others.
• Predominantly inattentive types tend to be distracted, get bored and wander off during tasks, forget things or instructions, daydream, and appear not to be listening. This type is sometimes misdiagnosed because they are not hyperactive and there are fewer behavior issues.
• Combined types show symptoms from both categories. This is actually the most common type of ADHD.
