Risk Factors Risk Factors for Chickenpox (Varicella) Between 75 - 90% of chickenpox cases occur in children under 10 years of age. Before the introduction of the chickenpox (varicella) vaccine, about 4 million cases of chickenpox were reported in the U.S. each year. Since a varicella vaccine became available in the U.S. in 1995, the incidence of disease and hospitalizations due to chickenpox has declined by nearly 90%. Chickenpox usually occurs in late winter and early spring months. It can also be transmitted from direct contact with the open blisters associated with either chickenpox or shingles. (Clothing, bedding, and other such objects do not usually spread the disease.) A patient with chickenpox can transmit the disease from about 2 days before the appearance of the spots until the end of the blister stage. This period lasts about 5 - 7 days. Once dry scabs form, the disease is unlikely to spread. Most schools allow children with chickenpox back 10 days after onset. Some require chil...
It is impossible to read any information on ADHD without finding out that the three major symptoms of ADHD are inattention, impulsiveness and hyperactivity. But what does this really mean? What do these symptoms look like on a day to day basis?
Each child is different. Each child has symptoms of ADHD that fall somewhere between mild and severe. Each child has a unique combination of symptoms. Ask any parent. They can go into detail on their child's behavior and their description might have some similarities to another parent's stories, but there will be differences as well. If this is the case, how then, can we figure out what is ADHD, what is normal behavior, and what might be something else entirely?
The following lists are compilations of how the three major symptoms may show up. It will be up to each family to decide if the behaviors warrant consideration, accommodations, behavioral interventions or medication to help in reducing symptoms.
Healthy older adults with no symptoms of Alzheimer’s disease are the focus of a large study involving 61 medical centers across the U.S., Canada and Australia. The Anti-Amyloid Treatment in Asymptomatic Alzheimer’s study aims to find out if Eli Lilly’s solanezumab, which failed in earlier studies to help people with Alzheimer’s symptoms, will help prevent Alzheimer’s if given long before symptoms appear. Solanezumab did show some promise in the earlier clinical trials for people who had mild cognitive impairment (MCI) which can signal an early stage of Alzheimer’s disease.
The Anti-Amyloid Treatment in Asymptomatic Alzheimer’s study is one of four NIH-supported Alzheimer’s studies to focus on innovative treatments, thus the umbrella name A4.
