What brain structure and function genes are linked to ADHD causes?

ByMy Patient Advice

Brain genes ADHD causes play a crucial role in understanding the biological foundations of ADHD. Research has shown that certain genes affect the development and function of the brain regions involved in attention, impulse control, and emotional regulation, which are key aspects of ADHD. These genetic differences affect brain structure and function in ways that predispose people to ADHD, which greatly increases the likelihood of developing the disorder. 

The prefrontal cortex, responsible for attention, decision-making, and impulse control, is particularly influenced by genetic factors. Brain genes ADHD causes are linked to changes in the development of this area of the brain, often leading to difficulties with concentration and behavioural regulation. ADHD is also significantly influenced by other genes that impact neurotransmitter systems, including dopamine. Neurogenetics ADHD explores how these genetic factors contribute to the condition, highlighting the importance of genetic research in understanding ADHD’s origins.

Common Symptoms Linked to Brain Genes and ADHD 

Here are some common symptoms associated with brain genes ADHD causes: 

Difficulty focusing and staying on task 

Children and adults with ADHD may struggle to focus, particularly during tasks that require sustained attention. This is linked to genetic variations that affect the prefrontal cortex. 

Impulsivity and emotional regulation issues 

Impulsivity, such as acting without thinking or emotional outbursts, is common in ADHD. These behaviours are often linked to genetic factors affecting the basal ganglia.
