If you’re searching for comprehensive ADHD testing in Southlake, you’re likely looking for clear answers—not assumptions. At Dr. Messina & Associates, we specialize in evidence-based ADHD evaluations for children, teens, and adults, providing thorough psychological testing that goes far beyond a brief screening or checklist.
ADHD can impact focus, organization, emotional regulation, academic performance, work productivity, and relationships. However, many symptoms overlap with anxiety, depression, learning disorders, trauma, or sleep issues. That’s why an accurate, structured evaluation is essential. Our ADHD specialists use standardized assessments, clinical interviews, behavioral measures, and cognitive testing to determine whether ADHD is present—and to identify strengths alongside challenges.
When you need reliable answers, professional ADHD testing provides clarity, direction, and confidence.
A true ADHD assessment involves much more than a short questionnaire. Our comprehensive evaluation process is designed to examine attention, executive functioning, processing speed, memory, impulse control, and emotional regulation in a detailed and objective way.
ADHD presents differently across the lifespan. In children, it may appear as hyperactivity, impulsivity, classroom struggles, or emotional outbursts. In teens, it often shows up as academic stress, disorganization, mood changes, or risk-taking behaviors. In adults, ADHD frequently presents as chronic procrastination, difficulty managing responsibilities, overwhelm, or career instability.
Our ADHD testing specialists tailor evaluations to the developmental stage of the individual. For children and teens, we collaborate with parents and may coordinate with schools when appropriate. For adults, we assess both current symptoms and childhood history to determine whether long-standing patterns are consistent with ADHD.
Receiving an accurate diagnosis can be life-changing. For many clients, testing brings relief—replacing years of self-blame with understanding. Whether you are seeking answers for yourself or your child, professional ADHD evaluation provides the foundation for effective treatment.
Without comprehensive testing, ADHD is often confused with anxiety, trauma responses, learning disabilities, or behavioral issues. When ADHD is missed, individuals may struggle unnecessarily. When it is misdiagnosed, treatment may not work.
Accurate psychological testing for ADHD allows us to:
• Create targeted therapy goals
• Guide school accommodations (IEP or 504 plans)
• Inform medication decisions when appropriate
• Improve parenting strategies
• Support workplace adjustments
• Strengthen self-esteem through understanding
At Dr. Messina & Associates, our integrated model means testing results can immediately inform therapy or psychiatric care under one roof. This coordinated approach leads to clearer treatment plans and more consistent progress.
