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.
There are three causes of ADHD symptoms: genetics, biology, and chemistry. Learning about these causes helps families understand that their daughter is not doing these behaviors intentionally.
Some environmental factors that cause ADHD include brain injuries and exposure to lead. Other factors, such as lack of sleep, increase the severity of ADHD symptoms. ADHD is a biological condition, meaning structural or chemical changes in the brain are likely to cause the symptoms.
Some of the common foods that can cause ADHD reactions include milk, chocolate, soy, wheat, eggs, beans, corn, tomatoes, grapes, and oranges. If you suspect a food sensitivity may be contributing to your child's ADHD symptoms, talk to your ADHD dietitian or doctor about trying an elimination diet.
Lack of Sleep
For others, anxiety, depression, and other conditions that come along with ADHD are to blame. Lack of sleep doesn't just make you tired. It can also worsen symptoms like lack of focus and problems with motor skills.
Foods rich in protein — lean beef, pork, poultry, fish, eggs, beans, nuts, soy, and low-fat dairy products — can have beneficial effects on ADHD symptoms. Protein-rich foods are used by the body to make neurotransmitters, the chemicals released by brain cells to communicate with each other.
You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents. In a recent Norwegian study, inherited risk was somewhat higher when a child's mother had ADHD compared to their father, but researchers weren't certain why that would be.
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.
Many American children have abnormally low levels of vitamin D. Newer research shows that children with ADHD have lower vitamin D levels than children without the condition. One study showed that expectant mothers with low vitamin D levels had a higher likelihood of their children having ADHD.
In general, ADHD doesn't get worse with age. Some adults may also outgrow their symptoms.
Many people think that ADHD is a result of trauma, but is it true? The answer is yes, but more for some people than others. The truth is that 90% of the time ADHD is not caused by trauma, but if the trauma is extreme enough, it can cause severe ADHD-like symptoms.
ADHD is a condition that both children and adults can have. The symptoms include an inability to focus, being easily distracted, hyperactivity, poor organization skills, and impulsiveness. Not everyone who has ADHD has all these symptoms. They vary from person to person and tend to change with age.
Differences in emotions in people with ADHD can lead to 'shutdowns', where someone is so overwhelmed with emotions that they space out, may find it hard to speak or move and may struggle to articulate what they are feeling until they can process their emotions.
Inattentiveness and difficulty concentrating may cause fatigue, especially among students and full-time employees working long days. Distractibility and poor focus can cause people with ADHD to quickly lose interest in activities or objects that once gave them pleasure as well.
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.
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children. Symptoms of ADHD include inattention (not being able to keep focus), hyperactivity (excess movement that is not fitting to the setting) and impulsivity (hasty acts that occur in the moment without thought).
Although anxiety and ADHD may occur together, ADHD is not an anxiety disorder. Sometimes, anxiety can occur independently of ADHD. Other times, it can be as a result of living with ADHD. A person who has ADHD and misses a work deadline or forgets to study for an important exam can become stressed and worried.
The symptoms may peak in severity when the child is seven to eight years of age, after which they often begin to decline. By the adolescent years, the hyperactive symptoms may be less noticeable, although ADHD can continue to be present.
Although genetics account for the majority of the risk, Strathearn points out that if we are seeing a true rise in ADHD, it seems likely that environmental factors play a role in the recent rise, “because genetics don't change that quickly,” he says, i.e. over the course of 20 years.
Foods rich in protein — lean beef, pork, poultry, fish, eggs, beans, nuts, soy, and low-fat dairy products — may have beneficial effects on ADHD symptoms. Protein-rich foods are used by the brain to make neurotransmitters — chemicals that help brain cells talk with each other.
