ADHD in Adults

ADHD Treatment Online in California

Attention-deficit/hyperactivity disorder is one of the most common — and most misunderstood — mental health conditions in adults. If you’ve spent years feeling scattered, forgetful, or chronically overwhelmed despite genuinely trying your best, you’re not alone, and you’re not lazy. ADHD is a neurodevelopmental condition with real, measurable effects on the brain, and it responds well to the right treatment. At Psych Wellness Spa, Kimberly Kaestner, PMHNP-BC, FNP-C, provides thoughtful, evidence-based ADHD care to adults across California through the convenience of telehealth.

What Is ADHD?

ADHD is a condition that affects the brain’s executive functioning — the set of mental skills that govern attention, impulse control, organization, and the ability to shift between tasks. It is not a childhood problem that people simply “grow out of.” Research consistently shows that roughly 60 percent of children diagnosed with ADHD continue to experience significant symptoms into adulthood, and many adults are never diagnosed until midlife, if at all.

ADHD is categorized into three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined presentation. Adults most often present with the inattentive type, which tends to be quieter and easier to miss — making it especially common for women and high-achieving individuals to reach adulthood without ever receiving an accurate diagnosis.

Signs and Symptoms of Adult ADHD

ADHD looks different in every person, but several patterns come up consistently in adults seeking evaluation. You may recognize yourself in more of these than you expect.

Inattentive Symptoms

• Difficulty sustaining focus on tasks that require mental effort
• Frequently losing items like keys, phones, or important documents
• Making careless mistakes even when you care deeply about the outcome
• Starting many projects but struggling to finish them
• Forgetting appointments, deadlines, or daily responsibilities
• Zoning out during conversations or meetings

Hyperactive and Impulsive Symptoms

• Feeling internally restless or “driven by a motor” even when sitting still
• Interrupting others or finishing their sentences
• Difficulty waiting your turn or tolerating delays
• Talking excessively or feeling compelled to fill silence
• Acting on impulse without fully thinking through consequences

Beyond these core symptoms, many adults with ADHD also experience emotional dysregulation — intense frustration, low distress tolerance, or a sensitivity to rejection known as rejection sensitive dysphoria. These emotional dimensions of ADHD are just as real as the attentional ones, even though they’re less widely discussed.

How ADHD Is Diagnosed

There is no single blood test or brain scan that diagnoses ADHD. Instead, diagnosis is clinical — meaning it’s based on a thorough evaluation of your history, symptoms, and how those symptoms have affected your life across different settings and over time. Kimberly conducts a comprehensive psychiatric intake that explores your current concerns, childhood history, family history, and any co-occurring conditions such as anxiety, depression, or sleep difficulties, which frequently accompany ADHD.

It’s also important to rule out other explanations for your symptoms. Thyroid disorders, sleep apnea, mood disorders, and anxiety can all produce inattention and restlessness. A careful evaluation ensures you receive the most accurate diagnosis and the most appropriate treatment plan — not just a label.

Treatment Options for ADHD

ADHD is highly treatable, and most people see meaningful improvement once they find the right combination of support.

Medication Management

Medication is often the most effective first-line treatment for ADHD, and it can be genuinely life-changing for many people. As a board-certified Psychiatric Nurse Practitioner with prescriptive authority in California, Kimberly can evaluate, prescribe, and carefully manage ADHD medications. This may include stimulant medications such as amphetamine or methylphenidate formulations, or non-stimulant options for those who prefer to avoid stimulants or have medical reasons to do so. Medication decisions are always individualized, monitored closely, and adjusted over time based on your response and any side effects.

Psychoeducation and Behavioral Strategies

Understanding how your brain works is itself a powerful intervention. Kimberly takes time to explain the neuroscience of ADHD in plain language and to discuss practical strategies for managing time, reducing overwhelm, and building routines that work with your brain rather than against it. For some individuals, a referral to a therapist who specializes in ADHD coaching or cognitive-behavioral therapy can complement psychiatric care meaningfully.

Treating Co-Occurring Conditions

ADHD rarely travels alone. Anxiety, depression, and insomnia are common companions, and treating one condition while ignoring the others rarely produces lasting results. Kimberly’s dual training as both a psychiatric and family nurse practitioner means she brings a whole-person perspective to your care.

Why Telehealth Works Especially Well for ADHD

It may seem counterintuitive, but telehealth is often an ideal fit for people with ADHD. Navigating traffic, finding parking, sitting in a waiting room, and managing appointment logistics can be genuinely difficult when executive functioning is already stretched thin. Telehealth removes those barriers entirely. You can attend your appointment from your home, your office, or anywhere private in California — on a schedule that fits your life rather than the other way around. Many patients find that eliminating the friction of in-person visits makes it far easier to stay consistent with their care.

What to Expect at Psych Wellness Spa

Your first appointment with Kimberly is a comprehensive psychiatric evaluation, typically lasting 60 minutes. You’ll have the opportunity to share your history in your own words, ask questions, and collaborate on what a treatment plan might look like for you. Follow-up appointments focus on monitoring how you’re responding to treatment, adjusting medications if needed, and addressing any new concerns that arise. Kimberly’s approach is unhurried and genuinely collaborative — she believes the person living with ADHD is always the expert on their own experience.

All appointments take place via secure, HIPAA-compliant video through a simple link sent to you before your visit. No special software or downloads are required.

Take the Next Step

If you’ve been struggling with focus, organization, or the quiet exhaustion of working twice as hard as everyone else just to keep up, you deserve a real evaluation — not another suggestion to try a planner. Kimberly Kaestner provides compassionate, evidence-based ADHD care to adults throughout California.
