![]() That’s the section of the brain responsible for tracking long term goals and obligations.īut in ADHD brains, the connections between neural networks are underdeveloped and weak, which means… The “automatic attention capture system” then sends a signal to the parietal lobe. ![]() Why? Welcome and unwelcome distractions activate the brain’s “automatic attention capture system,” which reflexively responds to sights and sounds. Or, an inattentive child may be so hyperfocused on a video game that the outside world fades away.ĪDHD makes it hard to pay attention on demand…and to break focus on something interesting. Inattention, a primary symptom of ADHD, may bring a shortage of focus – or an abundance.Īn inattentive child may struggle to focus on her teacher when squirrels are playing outside. Here, learn what activates the ADHD brain’s “automatic attention capture system,” and why it’s so hard to ignore distraction and refocus. Inattention, a primary symptom of ADHD, may bring a shortage of focus - or an abundance. That impacts inattention, impulsivity, and emotional regulation. The ability to self-regulate is managed across the brain in highly interconnected ways similar brain nodes regulate both attention and emotion - and when one area isn’t performing well, the others suffer, too.Brain networks - the way the different regions of the brain communicate - work differently for people with ADHD. Self-regulation weaves together all the older theories of ADHD into one cohesive picture it is also what allows humans to manage impulses, engage or disengage attention, and navigate between deliberate and automatic responses to different situations. Now, researchers understand that ADHD is primarily a disorder of self-regulation. What started as hyperkinetic impulse disorder - its primary symptom excessive hyperactivity - over time shifted to attention deficit disorder and a focus on problems with inattention, then to reward functioning, and later to executive functioning. Our understanding of ADHD has grown by leaps and bounds over the past 30 years. Stress, foods, and environmental toxins change the brain as well. More Than Just Genes: How Environment, Lifestyle, and Stress Impact ADHDĪDHD is a genetic disorder, but DNA is not working alone. Individuals with ADD, although typically shy, may engage in risk-taking and thrill-seeking activities as ways to experience a level of engagement they have difficulty sustaining in their daily lives. Their problem lies more in motivation than in inhibition.Ĭhallenge or risk, something to literally get their adrenaline pumping, can be key to keeping their attention and to eliciting optimum performance. People with ADD are not so much easily distracted as easily bored. A marked deficit in the release of DA and NE might cause sluggishness and under-arousal. ![]() Amphetamines affect both the reuptake and release of catecholamines. Addressing reuptake appears to be sufficient to help individuals with ADHD.Ī significant subset are helped by amphetamines rather than methylphenidate. Methylphenidate addresses catecholamine reuptake. ~There are marked similarities in the neurobiological and psychological effects of nicotine and methylphenidate.! Those with ADHD are more likely to smoke than are those with ADD. Those who are helped by methylphenidate often do best at low doses. Most respond positively to methylphenidate in moderate to high doses. Respond positively to methylphenidate ~Ritalin!Ī significant percentage are not helped by methylphenidate. Reading and language deficits and problems with mental mathematical calculations are more commonly comorbid with ADD than with ADHD. ADD children tend to be socially isolated or withdrawn. Internalizing disorders, such as anxiety or depression, are somewhat more common in children with ADD than those with ADHD. Social problems because too passive, shy, or withdrawnĮxternalizing behaviors, such as conduct disorder, aggressivity, disruptive behavior, and even oppositional defiant disorder are far more commonly comorbid with ADHD than with ADD. Social problems because too assertive and impulsive: butt in, take things belonging to others, fail to wait their turn, and act without first considering the feelings of others Primary deficit in working memory, especially prominent in auditory processing because of the demands it places on working memory A significant subset are hypoactive and sluggish and have slow response speeds.
