Can You Develop ADHD Later in Life?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurological disorder characterized by difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity (over-activity). ADHD is one of the most common mental disorders in children and adolescents, and can continue into adulthood. It is estimated that 4.4% of adults have ADHD, a rate that is expected to rise as better diagnostic criteria are developed. The question then arises, can you develop ADHD later in life, or are you born with it?
Genetics
Research suggests that ADHD is strongly linked to genetics. Studies have found that people with ADHD are more likely to have a relative, such as a parent or sibling, with the condition. However, it is important to note that not everyone with a family history of ADHD will develop the condition, and not everyone with ADHD has a family history of the condition.
Brain Development
Studies have also shown that people with ADHD have differences in the structure and function of their brains compared to those without the condition. For example, people with ADHD may have less gray matter in certain areas of their brains, which is associated with difficulty with executive functioning (planning, organizing, and decision-making). Additionally, research has found that people with ADHD have lower levels of dopamine, a neurotransmitter that is important for focus and attention.
Environmental Factors
While genetics and brain development may play a role in ADHD, environmental factors may also contribute to the development of the disorder. Studies have found that exposure to certain chemicals, such as lead, may increase the risk of developing ADHD. Additionally, research has shown that certain types of trauma, such as abuse or neglect, can also increase the risk of developing the condition.
Conclusion
While ADHD is strongly linked to genetics, there is evidence that environmental factors may also play a role in its development. It is important to note that not everyone with a family history of ADHD will develop the condition, and not everyone with ADHD will have a family history of the condition. Additionally, exposure to certain environmental factors, such as lead and trauma, may increase the risk of developing ADHD.
