The exact cause of ADHD is unknown, but research suggests that genetics, environmental factors, and brain chemistry may all play a role. Genetics are thought to be the most significant factor in the development of ADHD. http://adhdny1.com/ Studies have found that the disorder is more common in children who have a family history of ADHD. This suggests that the disorder may be inherited, although the exact genes responsible have yet to be identified.

Environmental factors may also contribute to the development of ADHD. Research suggests that exposure to certain toxins, such as lead, may increase the risk of developing the disorder. Other environmental factors, such as a lack of stimulation or a chaotic home environment, may also play a role.

Brain chemistry is also thought to be involved in the development of ADHD. Studies have found that people with ADHD have lower levels of certain neurotransmitters, such as dopamine and norepinephrine, which are responsible for regulating attention and behavior. This suggests that an imbalance in these chemicals may contribute to the symptoms of ADHD.

ADHD is typically diagnosed by a mental health professional, such as a psychologist or psychiatrist. During the evaluation, the doctor will ask questions about the patient’s symptoms and medical history. They may also conduct tests to rule out other conditions that may be causing the symptoms.

The doctor may also observe the patient’s behavior and ask them to complete tasks that measure their attention span and ability to focus. The doctor may also ask the patient’s family members and teachers to provide information about the patient’s behavior.

Once the doctor has gathered all the necessary information, they will make a diagnosis based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). To be diagnosed with ADHD, the patient must have at least six symptoms of inattention or hyperactivity-impulsivity that have been present for at least six months.

In conclusion, the exact cause of ADHD is unknown, but research suggests that genetics, environmental factors, and brain chemistry may all play a role. The disorder is typically diagnosed by a mental health professional using the criteria outlined in the DSM-5. If you think you or someone you know may have ADHD, it is important to seek professional help.
