Understanding ADHD

Attention-Deficit/Hyperactivity Disorder affects millions of Americans – approximately 4.4% of U.S. adults and 9.8% of children according to the National Institute of Mental Health. Yet ADHD remains widely misunderstood. Many people mistakenly view ADHD as laziness, a lack of willpower, or a character flaw. In reality, ADHD is a neurodevelopmental condition with a strong genetic basis, rooted in differences in how the brain regulates attention, impulse control, and executive function.

At its core, ADHD reflects difficulties with executive function – the brain’s ability to plan, organize, prioritize, manage time, and regulate emotions. People with ADHD often experience racing thoughts, difficulty filtering distractions, trouble initiating tasks despite good intentions, and emotional dysregulation that can feel overwhelming. These aren’t character weaknesses; they’re neurological differences that respond well to proper treatment.

A significant challenge in adult ADHD is that many people go undiagnosed or misdiagnosed for years. This is especially true for women, who often mask ADHD symptoms through high effort and compensatory strategies, only to “hit a wall” when life demands exceed their ability to compensate. Adults seeking evaluation often report a lifetime of underperformance, relationship struggles, or chronic disorganization that finally prompted them to seek help.

Types of ADHD

Predominantly Inattentive Presentation

This presentation centers on difficulty sustaining attention, maintaining focus, and completing tasks. People with predominantly inattentive ADHD often lose things frequently, struggle with time management, miss deadlines, and appear disorganized despite trying hard. In the workplace, they may excel at brainstorming but struggle with execution and follow-through. In relationships, they might have difficulty remembering important details shared by loved ones or show up late consistently. Inattentive ADHD was formerly called ADD and is more commonly seen in women, who may not display the hyperactivity that typically draws attention in children.

Predominantly Hyperactive-Impulsive Presentation

This presentation involves excessive restlessness, impulsivity, and difficulty inhibiting behavior. Adults with this type often fidget, have trouble sitting still through meetings, interrupt frequently in conversations, and act without thinking through consequences. They may be prone to risky behavior, impulsive spending, or speaking before considering the impact on others. While more obvious in children (who are bouncing off walls), adults may internalize some hyperactivity but still struggle with chronic restlessness, a feeling of “always being on,” and relationship friction from impulsive decisions or comments.

Combined Presentation

The combined presentation includes significant symptoms of both inattention and hyperactivity-impulsivity. People with combined ADHD experience the full range of challenges: difficulty focusing, chronic disorganization, time management struggles, emotional reactivity, restlessness, and impulsivity. This is the most common presentation overall and tends to cause the broadest functional impairment across work, relationships, and self-care. Combined ADHD often leads to anxiety or depression over time due to the compounding frustration and consequences of untreated symptoms.

ADHD Symptoms in Adults

Adult ADHD often looks very different from childhood ADHD. Rather than the obvious hyperactivity and disruptiveness seen in children, adults with ADHD typically struggle with executive function challenges that directly impact their professional and personal lives:

• Time management and chronic lateness. Adults with ADHD frequently underestimate how long tasks take, struggle to plan backward from deadlines, and show up late despite genuine intentions. This pattern often damages professional reputation and relationships.
• Losing things and forgetfulness. Keys, phone, important documents, and appointments are regularly misplaced. Many adults with ADHD report a lifestyle of searching for things or relying on others to remind them.
• Difficulty with task initiation and follow-through. Even with high motivation, starting tasks is often extremely difficult. The brain may freeze in the face of administrative or tedious work, despite knowing it’s important.
• Relationship strain. Inattention during conversations, forgetfulness about important details shared by partners, and emotional reactivity create friction. Partners often feel unheard or unvalued, while the person with ADHD feels perpetually criticized.
• Career and academic underperformance. Despite intelligence and capability, many adults with ADHD find themselves chronically underperforming, missing promotions, or struggling through school. The gap between potential and actual performance is a source of significant frustration.
• Emotional dysregulation. Many adults with ADHD experience quick shifts to frustration, anger, or overwhelm. Disappointments feel catastrophic; feedback feels like rejection. This emotional reactivity is sometimes mistaken for anxiety or depression.
• Rejection sensitivity dysphoria. A subset of people with ADHD experience intense emotional pain in response to perceived or actual rejection, criticism, or perceived social disapproval. This goes beyond normal disappointment and can significantly impact relationships and career choices.
• Chronic stress and burnout. The constant effort required to compensate for executive function difficulties eventually depletes reserves. Many adults don’t seek evaluation until they experience a crisis – burnout at work, relationship breakdown, or a major life transition that exceeds their coping capacity.

If this resonates with your experience, an evaluation with Dr. Fredes can provide clarity and a path toward real improvement in functioning and quality of life.

Getting an Accurate ADHD Diagnosis

Proper ADHD diagnosis matters for several critical reasons. First, ADHD medications – particularly stimulants – are controlled substances, and Texas regulations require thorough evaluation before prescribing. Second, ADHD frequently co-occurs with anxiety, depression, sleep disorders, and thyroid issues; an accurate diagnosis ensures you’re treating the actual problem, not just surface symptoms. Third, many adults spend years on anxiety or antidepressant medications that don’t address the core ADHD, leaving them frustrated and wondering why treatment isn’t working.

Dr. Fredes conducts comprehensive ADHD evaluations during a 60–90 minute initial appointment, which includes detailed developmental and symptom history from childhood through adulthood, assessment of current functional impairment across work, relationships, and daily living, screening for co-occurring conditions like anxiety, depression, sleep disorders, and thyroid dysfunction, review of prior evaluations or school records if available, medical history and lab work when indicated, and standardized rating scales combined with clinical interview.

This depth of evaluation is essential because ADHD presentations vary widely, overlap with other conditions, and require ruling out medical causes (thyroid disease, sleep apnea, anemia) that can mimic ADHD. You won’t receive a diagnosis after a 5-minute conversation. An accurate diagnosis takes time, thorough questioning, and clinical judgment.

Treatment Options for Adult ADHD

ADHD Medications Explained

How Stimulant Medications Work

Stimulant medications work by increasing dopamine and norepinephrine availability in the brain, particularly in regions responsible for attention, impulse control, and executive function. This increased availability helps the brain filter out distractions, sustain focus, initiate tasks, and regulate emotions more effectively. Stimulants are first-line treatment for ADHD because they have the strongest evidence base and produce the most noticeable improvement for most people.

Common stimulants include methylphenidate (Ritalin, Concerta, Adhansia) and amphetamines (Adderall, Vyvanse, Mydayis). Stimulants come in immediate-release (shorter duration, multiple daily doses) and extended-release (longer duration, typically once daily) formulations. The choice depends on your schedule, work demands, and how long you need coverage during the day.

Non-Stimulant Medications

Non-stimulants are preferred if you have cardiovascular concerns, significant anxiety, substance-use history, or side effects from stimulants. These medications work through different neurochemical pathways and often have a more gradual onset of action (2–4 weeks) compared to stimulants (which often work immediately). Common non-stimulants include atomoxetine (Strattera), which increases norepinephrine, guanfacine and clonidine, which are alpha-2 agonists often used for hyperactivity and impulsivity, viloxazine (Qelbree), a selective norepinephrine reuptake inhibitor, and bupropion (Wellbutrin), an atypical antidepressant that boosts dopamine and is especially useful if anxiety or depression co-occur.

Medication Side Effects and Management

Stimulants can cause appetite suppression, mild insomnia, increased heart rate, and occasional jitteriness, especially at higher doses. Most side effects diminish with time or are manageable through dose adjustment or timing changes. Non-stimulants may cause headache, nausea, dizziness, or sedation, but these typically resolve within the first few weeks. Dr. Fredes carefully monitors your response to medication at follow-up visits, adjusts dosing incrementally based on effectiveness and tolerability, and discusses strategies to manage any side effects (for example, taking medication with food, splitting doses, or adjusting timing).

The Titration Process

Finding the right ADHD medication is a deliberate, individualized process. After starting a medication or dose, you’ll have follow-up appointments at 1–2 week intervals to assess effectiveness and side effects. Dr. Fredes makes incremental adjustments based on your feedback and clinical response. Some patients find the right medication on the first try; others benefit from trying 2–3 medications or combinations to optimize symptom relief and tolerability. Patience, detailed feedback about what’s working and what isn’t, and realistic expectations about timeline (typically 4–12 weeks to reach optimal dosing) are essential for success.

ADHD Across the Lifespan

ADHD in Women

Women with ADHD are systematically underdiagnosed, often not identified until adulthood or not at all. This happens because girls are socialized to mask hyperactivity and impulsivity, excel academically through sheer effort (at the cost of burnout), and internalize restlessness. Women are more likely to have the inattentive presentation, which is quieter and easier to miss. Additionally, hormonal fluctuations across the menstrual cycle, pregnancy, and perimenopause significantly worsen ADHD symptoms, creating the false impression that ADHD waxes and wanes or that it’s purely hormonal. A comprehensive evaluation accounts for these patterns and ensures women receive appropriate treatment.

ADHD in College Students and Young Adults

College is often when undiagnosed ADHD becomes apparent. The transition from high school (where structure is externally imposed) to college (where self-direction is required) overwhelms many students. Similarly, early career transitions often unmask ADHD as job complexity increases. Young adults benefit enormously from diagnosis and treatment because addressing ADHD early prevents years of unnecessary struggle, relationship damage, and career setbacks.

ADHD and Parenting

Many adults seek ADHD evaluation after their child is diagnosed, recognizing themselves in their child’s symptoms. Parents with undiagnosed ADHD often struggle with consistency, follow-through on rules, emotional regulation during parenting stress, and organization of household logistics. Treatment for parental ADHD improves not only the parent’s wellbeing but also the entire family dynamic and the child’s outcomes.

ADHD in the Workplace

Untreated ADHD in adulthood commonly leads to underperformance, frequent job changes, missed promotions, and chronic stress. Many adults with ADHD thrive in high-stimulation, flexible, or entrepreneurial roles but struggle in structured corporate environments. Recognition of ADHD and appropriate treatment – whether through medication, coaching, workplace accommodations, or a career change – can be transformative for professional satisfaction and success.
