What is Attention Deficit Hyperactivity Disorder (ADHD)?

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common childhood disorders and can continue through adolescence and adulthood Symptoms include difficulty staying focused and paying attention, difficulty controlling behavior, and over activity.

ADHD has three sub-types:

1. Predominantly hyperactive-impulsive

● Most symptoms (six or more) are in the hyperactivity-impulsivity categories and fewer than six symptoms of inattention are present, although inattention may still be present to some degree.

2. Predominantly inattentive

● The majority of symptoms (six or more) are in the inattention categories and fewer than six symptoms of hyperactivity-impulsivity are present, although hyperactivity-impulsivity may still be present to some degree.

3. Combined hyperactivity-impulsive and inattentive

● Six or more symptoms of inattention and six or more symptoms of hyperactivity - impulsivity are present.

● Most children have the combined type of ADHD.

Possible causes:

1. Genes. Results from several international studies of twins show that ADHD often runs in families. Researchers are looking at several genes that may make people more likely to develop the disorder. Knowing the genes involved may one day help researchers prevent the disorder before symptoms develop. Learning about specific genes could also lead to better treatments.

2. Environmental factors. Studies suggest a potential link between smoking and alcohol use during pregnancy and ADHD in children. In addition, preschoolers are exposed to high levels of lead may have a higher risk of developing ADHD.

3. Food additives. Recent British research indicates a possible link between an increase in activity and consumption of certain food additives like artificial colors or preservatives. Research is under way to confirm the findings and to learn more about how food additives may affect hyperactivity.

Signs & symptoms:

Inattention, hyperactivity and impulsivity are the key behaviors of ADHD. To be diagnosed with the disorder, a child must have symptoms for six or more months and to a degree that is greater than other children of the same age.

Children who have symptoms of inattentive may:

● Be easily distracted, miss details, forget things and frequently switch from one activity to another.

● Become bored with a task after only a few minutes, unless they are doing something enjoyable.

● Have difficulty focusing attention on completing a task or learning something new.

● Not seem to listen when spoken to.

Children who have symptoms of hyperactivity may:

● Talk nonstop.

● Dash around, touching or playing with anything and everything in sight.

● Have trouble sitting still during dinner school and story time.

● Have difficulty doing quiet tasks or activities.

Children who have symptoms of impulsivity may:

● Be very impatient.

● Act without regard for consequences.

● Have difficulty waiting for things they want.

● Often interrupt conversations or others’ activities.

ADHD can be mistaken for other problems

Parents and teachers can miss the fact that children with symptoms of inattention have the disorder because they are often quiet and less likely to act out. They may get along well with other children, compared with those with the other sub-types, who tend to have social problems. But children with the inattentive kind of ADHD are not the only ones whose disorders can be missed. For example adults may think that children with the hyperactive and impulsive sub-types just have emotional or disciplinary problems.

1. If a kid shows six symptoms of inattention and seven symptoms of hyperactivity -impulsivity, which of the subtypes of ADHD does he belong to?
A.Predominantly hyperactive-impulsive.
B.Predominantly inattentive.
C.Combined hyperactive-impulsive and inattentive
D.It all depends.
2. Which of the following causes of ADHD has been confirmed by scientific research?
A.Genes.B.Smoking during pregnancy.
C.Food additivesD.Exposure to high levels of lead.
3. Which of the following is true according to the passage?
A.Kids who have symptoms of ADHD for more than four months can be diagnosed with ADHD.
B.The hyperactive and impulsive sub-types tend to be mistaken for emotional or disciplinary problems.
C.One of the symptoms of inattention is that kids become tired of a task easily even if they are doing something enjoyable.
D.It is claimed that artificial colors and preservatives have nothing to do with ADHD.

【推荐1】Children with long-term health conditions, such as asthma (哮喘), may be at greater risk of developing a mental health disorder in early adolescence compared to healthy children, according to a new study.

The findings, published in the journal Development and Psychopathology, show that kids with chronic illness exhibit higher rates of mental problems at age 10, and these health issues continue to be associated with poor mental health at ages 13 and 15.

In the study, the research team reviewed a sample of approximately 7,000 children to investigate the occurrence of mental health disorders, including anxiety or depression, and chronic illness. They found that children with chronic health conditions were approximately twice as likely at 10 and at 13 to present with a mental health disorder than healthy children. At age 15, children with chronic health problems were 60% more likely to present with such disorders.

“Although the link between chronic health conditions and mental health problems in childhood has been made before, this study provides the strongest evidence of it to data in the years of late childhood and early adolescence," said study author Dr. Ann Marie Brady. “The difference chronic illness makes to mental health is concerning, and the first impact can be seen even before adolescence, in late childhood."

The researchers also found that bullying and health-related absence from school were two most significant additional factors for children with mental health issues. The second one was identified as the most consistent factor predicting mental health problems over time.

“If children with chronic illness are more likely to miss school, or experience bullying, that can make the situation worse. Keeping an eye on school attendance and looking out for evidence of bullying amongst those children may help to find out who are most at risk.", said Dr. Brady.

1. The underlined term “chronic illness" in Paragraph 2 refers to a kind of disease_________
A.causing a lot of deathsB.causing absent-mindedness
C.lasting for a long timeD.leading to mental disorders
2. By the findings of this study, we know that_________
A.chronic illness leads to the mental health disorder in early adolescence
B.healthy young adolescents have no chance of having mental problems
C.adolescents with illness are more likely to develop mental health disorders
D.chronic illness has some relation to mental problems in early adolescence
3. What is special about this study?
A.It makes a new discovery based on the findings of previous studies
B.It draws a more accurate conclusion based on the previous studies
C.It questions the accuracy of the findings by the previous studies
D.It draws more attention to adolescents' health than previous studies
4. Which of the following can best help to decide if children with chronic illness tend to have mental problems?
A.Their school attendance.B.Their physical conditions.
C.Their tolerance of bullying.D.Their tendency for bullying.

【推荐2】We all know the saying, “Nobody is perfect.” It has been planted in our brains since we were children, and of course, it is the truth. So if nobody is perfect, why do we have such a hard time admitting when we are in trouble or need help?

Like many other young people trying to get through their first year of college, I felt anxiety, and it had its grips on me pretty tight. It began getting in the way of my life, and I had to sit down and tell myself that my behavior was not healthy and there was a solution. Finally, I decided to turn to therapy (精神疗法).

Therapy. It has such a negative stigma (污名), but why ? Does going to therapy mean that you are failing as a person or that you cannot fix your problems on your own? No. Going to therapy means that you are strong enough to recognize that something inside your head is not working correctly, and you are brave enough to try to fix it.

After a couple of weeks, many parts of my life became so much clearer. I began to understand that I, myself, am my worst enemy, which was pretty frightening. But, although frightened, I knew that it was only I who could guide me towards feeling better, and that was extremely empowering.

I have been guided towards a healthier mindset, one that is positive and powerful. I have been able to understand that no matter what happens in my life. I will always be okay.

A lot of people do not understand that it is normal to have negative feelings and sometimes to feel like we have lost control over certain parts of our lives. Seeing a therapist can greatly change your way of thinking about something if you keep your mind open and I am so thankful that I decided to go and do something for myself.

If you are in need of help, you can go to therapy and then everything will be okay.

1. In the author’s opinion, going to therapy        .
A.means you are failing as a person
B.means you are brave enough to solve your problems
C.can make others think wrongly about you
D.can be quite unnecessary and helpful

【推荐3】The cancer death rate in the U.S. fell by the most on record as advances in treatments for lung tumors (肿瘤) like video-assisted surgery helped prolong the lives of patients.

The death rate from cancer has been gradually declining for 26 years, thanks in large part to fewer people smoking cigarettes. But from 2016 to 2017, the most recent period available, it dropped by 2.2%, the most ever in a single year, according to a report released Wednesday by the American Cancer Society. That compares with an average 1.5% yearly decline over the decade. The drop translates to roughly 2.9 million fewer cancer deaths than would have occurred had death rates remained at their peak. For lung cancer specifically, the death rate declined 4.3% annually from 2013 to 2017.

"It is really lung cancer that is driving this," said Rebecca Siegel, scientific director of surveillance research at the American Cancer Society, and lead author on the new study. "We found increases in survival for lung cancer at every stage in diagnosis.”, She attributed the lower deaths to improvements in treatments, including video-assisted surgery that enables more patients with early lung tumors to become eligible for operations; more precise radiation treatment; and better scanning technology that allows doctors to better assess the stage of tumor, so the patient gets the best treatment right away. At later stages of illness, new, targeted drugs that aim at specific disease-causing genes are helping patients whose tumors have those genetic flaws (缺陷).Overall, lung cancer death rates have dropped by 51% for men since their peak in 1990, and by 26% for women since their peak in 2002.

There's the potential for more progress in future reports. That's because the latest death-rate statistics go only through 2017, and likely don't include the potential impact in lung cancer death from immune-therapy drugs. They became widely used in lung cancer only in the past few years.

The report, based on U.S. government data, isn't all good news. Prostate (前列腺)cancer death rates have leveled off recently after a period of decline. That may be because many doctors pulled back on using the controversial prostate-specific antigen test, or PSA, which can spot the disease but can lead to over-treatment of men who may never have                                        died from their tumors.

"Though it was definitely causing harm, it was also contributing to declines in death," Siegel said. What's needed now is better screening tests to detect only the prostate cancers that will go on to cause harm.

Population death rates are considered one of the most reliable ways of measuring progress in cancer treatment and prevention. By contrast, cancer survival rates can sometimes be influenced by improvements in diagnosing tiny, early stage tumors that wouldn't necessarily be deadly.

1. According to paragraph 2, ______.
A.cancer death rate reached its peak in 2017
B.death rate decreases over the past 2 decades
C.2.9 million people die of cancer in America every year
D.most of the cancer patients in America suffer from lung cancer
2. We can learn from the passage that ______.
A.female death rate of lung cancer drops more than that of male
B.targeted drugs have led to rapid increase in cancer death rates
C.better scanning technology will lead to improvement in treating genetic flaws
D.improper use of prostate-specific antigen test can lead to over-treatment of men
3. The underlined expression "level off” in paragraph 5 means ______.
A.remain unchangedB.show up
C.take offD.become sharp
4. What might be the best title of the passage?
A.Medical Progress Prolonging Patients’ Lives
B.Cancer Death Rates Dropping at the Fastest Pace
C.Significant Improvement in Treating Lung Cancer
D.Advanced Technologies Applied in Cancer Treatment
