In fact, ADHD can sometimes make you feel as though a fog has seeped into your brain. Your reaction time slows. It can be harder to recall information, process your thoughts, and find the right words to say what you want to say. This article explains the relationship between ADHD and the condition known as brain fog.
People with ADHD will have at least two or three of the following challenges: difficulty staying on task, paying attention, daydreaming or tuning out, organizational issues, and hyper-focus, which causes us to lose track of time. ADHD-ers are often highly sensitive and empathic.
But over the past two decades, research has shown that the brains of patients with ADHD look different than the brains of people who don't have ADHD. These differences show up on various brain scans in multiple types of imaging, including a functional MRI, called an fMRI.
Neuroimaging studies have revealed the structural differences in the ADHD brain. Several studies have pointed to a smaller prefrontal cortex and basal ganglia, and decreased volume of the posterior inferior vermis of the cerebellum — all of which play important roles in focus and attention.
Brain development is also slower in people with ADHD. The neural pathways don't connect and mature at the same rate, making it harder to pay attention and focus. This can impair executive function, which handles organization and routine tasks.
At the brain circuitry level, the superior longitudinal fasciculus (SLF) and cortico-limbic areas are dysfunctional in individuals with ADHD.
On average, the brains of ADHD children matured about three years later than those of their peers. Half of their cortex has reached their maximum thickness at age 10 and a half, while those of children without ADHD did so at age 7 and a half; you can see an evocative Quicktime video of this happening online.
Brain magnetic resonance imaging (MRI) can be used to identify people with attention-deficit/hyperactivity disorder (ADHD) from patients without the condition, according to a new study published in Radiology. Information from brain MRIs may also help to distinguish among subtypes of ADHD.
As you know, one trademark of ADHD is low levels of the neurotransmitter dopamine — a chemical released by nerve cells into the brain. Due to this lack of dopamine, people with ADHD are "chemically wired" to seek more, says John Ratey, M.D., professor of psychiatry at Harvard Medical School in Boston.
ADHD was the first disorder found to be the result of a deficiency of a specific neurotransmitter — in this case, norepinephrine — and the first disorder found to respond to medications to correct this underlying deficiency. Like all neurotransmitters, norepinephrine is synthesized within the brain.
Type 6: Ring of Fire ADD
Symptoms: primary ADD symptoms plus extreme moodiness, anger outbursts, oppositional, inflexibility, fast thoughts, excessive talking, and very sensitive to sounds and lights. I named it Ring of Fire after the intense ring of overactivity that I saw in the brains of affected people.
Attention Deficit Hyperactivity Disorder (ADHD) is a neurological disorder that affects a person's ability to control their behavior and pay attention to tasks.
People with ADHD of the inattentive type have trouble paying attention to details, are easily distracted, often have trouble organizing or finishing tasks and often forget routine chores (such as paying bills on time or returning phone calls).
Adults with ADHD may find it difficult to focus and prioritize, leading to missed deadlines and forgotten meetings or social plans. The inability to control impulses can range from impatience waiting in line or driving in traffic to mood swings and outbursts of anger. Adult ADHD symptoms may include: Impulsiveness.
ADD can sometimes go unnoticed because the symptoms may be less obvious. ADHD is more often diagnosed in boys than girls. Girls are more likely to have symptoms of inattentiveness only, and are less likely to show disruptive behaviour that makes ADHD symptoms more obvious.
Others with ADHD show mostly hyperactive-impulsive symptoms like fidgeting and talking a lot, finding it hard to sit still for long, interrupting others, or speaking at inappropriate times. Many people with ADHD have a combination of inattentive and hyperactive-impulsive symptoms.
Stimulants are believed to work by increasing dopamine levels in the brain. Dopamine is a neurotransmitter associated with motivation, pleasure, attention, and movement. For many people with ADHD, stimulant medications boost concentration and focus while reducing hyperactive and impulsive behaviors.
If your child has ADHD, they may have low levels of a brain chemical called dopamine. That's part of a mix of their genes, environment, and brain function that experts believe may cause ADHD.
Attention-deficit hyperactivity disorder (ADHD) can't be diagnosed with a physical test, like a blood test or an X-ray. Instead, a health professional uses an evaluation process to diagnose ADHD.
There is no specific ADHD test. Screening usually involves several steps, including: A physical exam to find out if a different type of disorder is causing symptoms. An interview.
There is no single test used to diagnose ADHD. Experts diagnose ADHD when symptoms impact a person's ability to function and they've shown some or all of the symptoms on a regular basis for more than 6 months and in more than one setting.
A: ADHD brains need more sleep, but find it doubly difficult to achieve restfulness. It is one of those ADHD double whammies: ADHD makes it harder to get enough sleep, and being sleep deprived makes it harder to manage your ADHD (or anything else).
ADHD is often also associated with lower intelligence quotient (IQ; e.g., Crosbie and Schachar, 2001). For instance, Frazier et al. (2004) reported in their meta-analysis that in comparison to individuals without ADHD, individuals with ADHD score an average of 9 points lower on most commercial IQ tests.
ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
