Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Causes of ADHD
In addition to genetics, scientists are studying other possible causes and risk factors including: Brain injury. Exposure to environmental risks (e.g., lead) during pregnancy or at a young age. Alcohol and tobacco use during pregnancy.
Overall population incidence is felt to be 8%-10%. Several investigations have demonstrated that children who have ADHD usually have a least one close relative (child or adult) who also has ADHD. At least one-third of all fathers who have ADHD will produce a child with ADHD.
ADHD symptoms start before age 12, and in some children, they're noticeable as early as 3 years of age. ADHD symptoms can be mild, moderate or severe, and they may continue into adulthood. ADHD occurs more often in males than in females, and behaviors can be different in boys and girls.
ADHD, also called attention-deficit disorder, is a behavior disorder, usually first diagnosed in childhood, that is characterized by inattention, impulsivity, and, in some cases, hyperactivity.
People with ADHD may have trouble completing thoughts when talking or finishing magazine articles and books. Failing to pay attention to details or constantly making careless mistakes. Often having trouble organizing tasks and activities. Often avoiding tasks that require mental effort over a long period of time.
There is no single test used to diagnose ADHD. Experts diagnose ADHD when symptoms impact a person's ability to function and they've shown some or all of the symptoms on a regular basis for more than 6 months and in more than one setting.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children.
Many children (perhaps as many as half) will outgrow their symptoms but others do not, so ADHD can affect a person into adulthood.
The exposure to stressful life events, and—more specifically—Childhood Trauma, has been shown to predict ADHD onset as well as persistence of the disorder into adulthood (Biederman et al. 1995; Friedrichs et al.
Anita Thayer, M.D. analyzed the DNA from 366 children with ADHD. A comparison with DNA from unaffected patients showed an abnormality in the sequences. Thayer's study shows that the ADHD group of children had larger and more frequent variations. Fathers with ADHD will pass this code discrepancy to offspring.
Biological: ADHD is associated with the way certain neurotransmitters (chemicals in the brain that help control behavior) work, especially dopamine and norepinephrine, and this difference causes changes in two different attentional networks of the brain — the default network, associated with automatic attention and the ...
People with ADHD will have at least two or three of the following challenges: difficulty staying on task, paying attention, daydreaming or tuning out, organizational issues, and hyper-focus, which causes us to lose track of time. ADHD-ers are often highly sensitive and empathic.
The three main symptoms of ADHD are hyperactivity, impulsivity, and inattention. All of these impact behavior, mood, and thinking. That's why ADHD meets the criteria for mental illness.
A well-balanced diet, exercise, and meditation are all good options for individuals looking to reduce their ADHD symptoms. However, while these natural ADHD remedies may reduce the severity of certain ADHD symptoms, they do not address the individual's underlying brain dysregulation.
ADHD: a disabling condition
It is recognized as a disability under the 1992 Disability Discrimination Act.
ADHD is diagnosed by the observation of behavioural symptoms. If you're concerned about your child's behaviour, your GP is a good place to start. Your GP might refer your child to a paediatrician, a psychologist or a child psychiatrist for a diagnosis of ADHD (or other condition).
Still, while environmental and cultural factors can alter behavior and child development, research confirms that ADHD is primarily a biologically-based disorder.
As you know, one trademark of ADHD is low levels of the neurotransmitter dopamine — a chemical released by nerve cells into the brain. Due to this lack of dopamine, people with ADHD are "chemically wired" to seek more, says John Ratey, M.D., professor of psychiatry at Harvard Medical School in Boston.
Autism spectrum disorder and ADHD are related in several ways. ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
A formal diagnosis of ADHD can only be made by qualified health professionals. Whilst general practitioners, and other front-line health providers may have useful information and experience in identifying ADHD symptoms, the diagnosis needs to be made by a paediatrician or a child psychiatrist.
Attention-deficit hyperactivity disorder (ADHD) can't be diagnosed with a physical test, like a blood test or an X-ray. Instead, a health professional uses an evaluation process to diagnose ADHD.
No. Diagnosing ADHD requires extensive knowledge, skills and training and ADHD must be diagnosed by a certified professional like a medical doctor or psychiatrist.
