What is it?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects both children and adults. A type of neurodiversity. It is characterized by persistent patterns of inattention, hyperactivity, and impulsivity that can significantly impact various aspects of life, including academic performance, work productivity, and relationships.

Inattention refers to difficulties sustaining attention, being easily distracted, and having trouble organizing tasks or following instructions. Hyperactivity manifests as excessive and often uncontrollable motor activity, such as fidgeting, restlessness, and an inability to stay seated. Impulsivity involves acting without considering the consequences, interrupting others, and having difficulty waiting for one's turn.

ADHD is believed to arise from a combination of genetic, environmental, and neurological factors. One prominent theory suggests that a dysregulation of neurotransmitters, particularly dopamine, plays a crucial role. Dopamine is a chemical messenger in the brain involved in regulating motivation, reward, and executive functions like attention and impulse control.

Research suggests that individuals with ADHD may have lower levels of dopamine or impaired dopamine receptor functioning, particularly in brain regions associated with attention and reward processing. This dopamine dysregulation may contribute to the core symptoms of ADHD and affect motivation, focus, and self-control.

Medications used to treat ADHD, such as stimulants like methylphenidate or amphetamines, work by increasing the availability of dopamine in the brain, which helps improve attention and reduce hyperactivity. These medications can help restore the balance of neurotransmitters and enhance the functioning of neural circuits implicated in ADHD symptoms.

However, it's essential to recognize that ADHD is a complex condition, and dopamine dysregulation is just one aspect of its underlying neurobiology. Other factors, such as abnormalities in other neurotransmitters and brain regions involved in cognitive control, may also contribute to the disorder.

Understanding ADHD as a multifaceted condition that involves the interplay of genetic, environmental, and neurochemical factors helps foster empathy and promotes effective interventions and support for individuals with ADHD. Education, behavioral strategies, therapy, and medication can all play important roles in managing ADHD symptoms and improving quality of life for those affected by the disorder.
