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.
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 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.
There is growing evidence that ADHD is emerging for the first time in adulthood for a number of people. It was only recently that the Diagnostic and Statistical Manual of Mental Disorders acknowledged, in the fifth edition, that ADHD sometimes develops after childhood.
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.
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.
A growing body of research links ADHD onset and severity to psychosocial and neurocognitive factors, such as the experience of stressful life events and memory processes.
Trauma and traumatic stress, according to a growing body of research, are closely associated with attention deficit hyperactivity disorder (ADHD or ADD). Trauma and adversity can alter the brain's architecture, especially in children, which may partly explain their link to the development of ADHD.
ADHD can't be prevented or cured. But spotting it early, plus having a good treatment and education plan, can help a child or adult with ADHD manage their symptoms.
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. Barkley explains that the heritability of ADHD runs around 80 percent.
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 ...
Boys (13%) are more likely to be diagnosed with ADHD than girls (6%). Black, non-Hispanic children and White, non-Hispanic children are more often diagnosed with ADHD (12% and 10%, respectively), than Hispanic children (8%) or Asian, non-Hispanic children (3%).
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children.
There is no specific physical test or written test that can make the diagnosis of ADHD. It is a diagnosis based on the child's history of behavioral symptoms at home and at school.
If you are concerned about whether a child might have ADHD, the first step is to talk with a healthcare provider to find out if the symptoms fit the diagnosis. The diagnosis can be made by a mental health professional, like a psychologist or psychiatrist, or by a primary care provider, like a pediatrician.
ADHD is a mental health condition typically characterized by inattentive, hyperactive, or impulsive behavior. On the other hand, trauma is a mental, emotional, or physical response to a shocking or distressing event or series of stressful events.
Traumatic brain injury (TBI) is a frequent cause for hospitalization in young children and teenagers. It's associated with developing mental conditions, including secondary ADHD, a form of ADHD that develops following an injury.
In addition to a formal treatment plan—whether medications, therapy, or both—prioritizing adequate amounts of restful sleep, consistent exercise, mindfulness practices, and a nutritious diet can help those with ADHD reduce hyperactivity, improve focus, and even boost mood.
Differences. The symptoms of ADHD are slightly different from those of anxiety. ADHD symptoms mainly involve issues with focus and concentration. Anxiety symptoms, on the other hand, involve issues with nervousness and fear.
ADHD and anxiety are closely connected. Anxiety disorder is ADHD's most common comorbidity — in no small part because the ADHD experience makes for a life characterized by stress and worry. This is especially true in the time of the pandemic, when new coping mechanisms are required.
Over time, insomnia may worsen as people start to develop feelings of stress related to bedtime. Many people with ADHD experience daytime sleepiness and difficulty waking up as a result of poor sleep. Others experience restless, non-refreshing sleep with multiple nighttime awakenings.
No. Diagnosing ADHD requires extensive knowledge, skills and training and ADHD must be diagnosed by a certified professional like a medical doctor or psychiatrist.
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.
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).
