ADHD, or Attention Deficit Hyperactivity Disorder is a neurodevelopment disorder that affects both children and adults. It is characterized by signs such as difficulty with focus, hyperactivity, and impulsivity (Guy-Evans, 2022).

Facts About ADHD (Amino Science, 2018; National Institute of Mental Health, 2014)
- According to epidemiological data, approximately 5% of adults have ADHD. That represents over 11,000,000 people in the US. It occurs in both men and women and, in the majority of cases, persists throughout the lifespan.
- ADHD usually persists throughout a person’s lifetime. It is NOT limited to children. Since ADHD is a neuro-behavioral condition, there is no cure, and the majority do not outgrow it. Approximately two-thirds or more of children
- Individuals with ADHD Have Abnormal Neurotransmitter. Function High-quality research shows that individuals with ADHD have chemical abnormalities in their brains related to the neurotransmitters dopamine and serotonin, which carry signals between neurons along pathways governing crucial functions.
- Lifetime prevalence. The lifetime prevalence of ADHD is estimated at around 8.7%, with males being affected at a rate of approximately 13% and females at 4.2%
Important Vocab (Speilman et al., 2020)
- Dopamine: Is a brain chemical that regulates emotional responses and is involved in motivation, feelings of pleasure, and rewards
- Cognitive behavioral therapy (CBT): Is an evidence-based form of psychotherapy that focuses on the connections between thoughts, emotions, and behaviors.
- ADHD medications (stimulant): may help people with ADHD focus better by increasing dopamine levels in the brain.
Diagnosing ADHD (CDC, 2024; NHS, 2021)
There is no single test to diagnose ADHD Still, there are similar problems, such as sleep disorders, anxiety, depression, and certain types of learning disabilities, that can also have symptoms similar to ADHD.
The most common way for ADHD to be diagnosed is by a healthcare professional like a clinical psychologist or psychiatrist. For children and adolescents, they must have at least 6 symptoms according to the DSM-5. For adults, they must have at least 5 symptoms. For children, adolescents, and adults, their symptoms must also be negatively affecting their quality of life to meet the diagnosis this way.

ADHD and the Brain (Speilman, 2020)
There are multiple areas of the brain that are believed to be affected when someone has ADHD, but especially the frontal lobe, which controls behavior, emotions, and attention. There is no definitive brain test for ADHD, so brain scans comparing people with ADHD to Normal Brains are unreliable because the people are medicated with stimulants that will affect those brain scans.

Treating ADHD (CDC, 2024)
The current treatment for ADHD includes both therapy and medication for both adults and children
For therapy, you can use behavior therapy to help manage your ADHD
For medication, both adults and children can use stimulant or non-stimulant medication
Stimulant medication: is a fast-acting medication to help you have fewer ADHD symptoms
Non-Stimulant medication: Have the same effect as stimulant medication but they don't work as fast. They overall better improve your symptoms and have a longer lasting effect
ADHD Medication. Attentive, hyperactive, and impulsive symptoms related to ADHD can be treated by stimulant medication (such as Adderall) and non-stimulant medication (including Strattera).
Anxiety Medication. People with anxiety can benefit from Selective Serotonin Reuptake Inhibitors (SSRIs), a class of medication that prevents your brain from reabsorbing serotonin, the neurotransmitter connected to feelings of calm and happiness. SSRIs are taken every day. Some prescribers may also recommend benzodiazepines, medication that can be taken on an as-needed basis for panic attacks or severe anxiety symptoms.

Mindfulness-Based Cognitive Therapy can improve emotional regulation and executive functioning.
Dialect Behavioral Therapy can teach the patient utilizing Mindfulness, Interpersonal Effectiveness, and Distress Tolerance to reduce ADHD symptoms.
Supportive Psychotherapy can help the client learn coping skills and distressing skills to improve time management and organization.

Famous People with ADHD
Study finds that children with ADHD present memory problems, including working memory deficits.
De Beni and his colleagues (1998) conducted two studies examining working memory in children with ADHD symptoms. The first study compared 22 children (17 males, 5 females, aged 8-12 years) who had been teacher-referred for ADHD symptoms with a control group. Researchers assessed their performance using a listening span test, where participants had to identify animal names in word strings while remembering the final word of each string. The second study expanded this investigation by examining 34 children with ADHD symptoms (25 males, 9 females, mean age 9.26 years) and 50 control children. This time, researchers employed a visuospatial working memory task that paralleled the verbal task from the first study. Both studies yielded consistent results: children with ADHD symptoms demonstrated significant difficulties remembering the last item in sequences and experienced more intrusive memories of non-final items. The researchers concluded that these working memory deficits stem from an inability to suppress information that must initially be processed but later excluded from memory.
