One of the most common reasons people come to Lifespan for psychological testing in Conejo Valley is suspected ADHD. It might be a parent watching their fifth grader fall further behind despite working harder than peers. It might be a college student who has finally hit a wall they cannot study their way out of. It might be a 38-year-old executive who can run a department but cannot finish their own expense reports. ADHD looks different at different ages, and getting tested matters more than most people realize.

What ADHD actually is, and why "trying harder" does not fix it

ADHD is a neurodevelopmental condition. The current understanding, supported by decades of imaging and longitudinal research, is that ADHD reflects differences in the brain networks that manage executive function: working memory, sustained attention, response inhibition, and self-regulation. The lived experience is consistent. People with ADHD know what they need to do, often in painful detail. They just cannot reliably make their brain do it on demand. Effort is not the missing ingredient.

Signs that warrant evaluation in children

  • A persistent gap between intelligence and academic output, especially when the child is clearly smart in conversation but cannot get work done.
  • Homework that takes three times longer than it should, with meltdowns by the end.
  • Trouble with multi-step instructions, even simple ones.
  • Excessive forgetfulness with things they actually care about (not just chores).
  • Difficulty sitting through age-appropriate tasks, fidgeting, blurting, interrupting.
  • Teachers reporting that the child "could do this if they just focused" , that exact sentence shows up in almost every ADHD family's intake history.

Signs that warrant evaluation in teens and adults

  • Chronic underperformance relative to ability, especially in unstructured environments like college.
  • Procrastination that feels involuntary, not chosen.
  • Time blindness: missing appointments, underestimating tasks, no internal sense of how long things take.
  • Difficulty starting tasks that are not urgent, even ones you want to do.
  • Emotional dysregulation: outsized reactions, rejection sensitivity, low frustration tolerance.
  • A long history of being called "lazy," "inconsistent," or "not living up to your potential."
  • A family history of ADHD (it runs strongly in families).

What a real ADHD evaluation actually involves

This is where many people get misled. A 15-minute checklist with a pediatrician is not an ADHD evaluation. A comprehensive ADHD assessment at Lifespan typically includes:

  • Clinical interview: developmental history, symptom timeline, current functioning across settings.
  • Standardized rating scales: Conners, BASC, BRIEF, ASRS for adults, completed by the client and ideally a parent, spouse, or teacher.
  • Cognitive testing: WISC or WAIS, processing speed and working memory specifically.
  • Attention and executive function tasks: continuous performance tests, executive function batteries.
  • Differential diagnosis: ruling out or noting co-occurring concerns like anxiety, learning disabilities, sleep issues, or trauma that can mimic or accompany ADHD.
  • Feedback session and written report: a clear diagnostic picture and concrete recommendations.

A real evaluation runs 8 to 15 hours of clinical work across testing, scoring, and report writing. That is the standard, and that is what produces a diagnosis that holds up to a school, an employer, or a prescriber.

What changes after a diagnosis

For most clients, the diagnosis itself is half the value. Years of being told they were lazy, scattered, or insufficiently disciplined finally make sense. The rest of the value is what comes next: medication consideration with a prescriber, evidence-based behavioral strategies, school accommodations through a 504 plan or IEP, ADA accommodations for college boards, the bar exam, or work, and therapy tailored to ADHD rather than generic anxiety treatment.

Why people in Westlake Village, Thousand Oaks, and Agoura Hills come to Lifespan

Conejo Valley has very few practices that do comprehensive psychological testing. Most pediatricians refer out. Most general therapy practices refer out. Lifespan's psychologists, including Dr. Adela Gharabeki, do this work as a specialty. We see kids, teens, and adults, and we write reports that schools, prescribers, and accommodations offices actually use.

If you are on the fence

The most common regret we hear at intake is "I wish I had done this years ago." If you have been wondering whether ADHD is part of the picture, a 30-minute consultation call is enough to give you a sense of whether testing is the right next step. We are happy to do that with no commitment.
