Comprehensive Neuropsychological Evaluations in New Jersey
Dr. Hahn provides comprehensive neuropsychological evaluations for children, adolescents, and young adults in New Jersey. Each evaluation is individualized, combining objective testing with clinical expertise to identify cognitive strengths and areas for growth using an affirming approach, support accurate diagnosis, and guide meaningful recommendations for families, schools, and healthcare providers.
What Is Neuropsychology?
Neuropsychology integrates neurology and psychology into one field. A neuropsychologist is specially trained to evaluate brain-behavior relationships, identifying cognitive strengths and weaknesses that inform diagnosis and guide recommendations for parents, educators, healthcare providers, and legal professionals.
What Is a Board Certified Neuropsychologist?
Board certification is the highest standard in the field of neuropsychology. A board certified neuropsychologist has completed a doctoral degree, a two-year postdoctoral fellowship in a medical setting, and at least two years of clinical experience, and has passed a rigorous examination process including case submission and an oral review.
​
When choosing a neuropsychologist, look for the letters ABPP or ABPP-CN after their name. This indicates board certification through The American Board of Professional Psychology (ABPP) and/or The American Board of Clinical Neuropsychology (ABCN). Providers without these credentials do not meet the full definition of a clinical neuropsychologist.
​
Dr. Hahn holds dual board certification and brings this standard of expertise to every evaluation she conducts.
Why Training Matters When Choosing a Neuropsychologist for Your Child
Not all providers who call themselves neuropsychologists have the same training, and when it comes to evaluating children and adolescents, that distinction matters enormously.
Neuropsychologists are trained in one of three ways: as pediatric specialists with specific training in evaluating individuals from early childhood through adolescence, as adult specialists whose clinical expertise is focused on adult populations, or as lifespan neuropsychologists meaning they are trained to understand the entire range of development. While an adult trained neuropsychologist may offer services to younger patients, they have not completed the specialized developmental training required to fully understand a still-developing brain like a lifespan or pediatric neuropsychologist.
For children and adolescents, working with a lifespan trained or pediatric neuropsychologist ensures that your child's evaluation is interpreted through a developmental lens. Cognitive, emotional, and behavioral patterns that are typical at one stage of development may look very different at another. A neuropsychologist without pediatric or lifespan training may not have the clinical background to make that distinction accurately.
Dr. Hahn is a lifespan trained, dual board certified neuropsychologist with specialized expertise in evaluating children, adolescents, and young adults across the full developmental spectrum. She completed her doctoral clinical training at the University of Florida's Shands Hospital in their pediatric neuropsychology program and her post-doctoral training at Yale University's Department of Neurosurgery's pediatric department. When seeking a neuropsychological evaluation for your child or teenager in New Jersey, it is worth asking about your provider's specific training background and board certification credentials, specifically seeking a provider with the distinction of the pediatric subspeciality board certification.
Pediatric Neuropsychological Testing in New Jersey
Families across New Jersey seek pediatric neuropsychological testing to better understand how their child learns, processes information, and navigates emotional and social challenges. A comprehensive neuropsychological evaluation provides objective data that goes beyond what a questionnaire, teacher report or one hour clinical interview can offer, giving parents, educators, and providers a complete picture of a child's strengths and areas of need.
​
Dr. Hahn provides neuropsychological testing for children and adolescents in New Jersey, with expertise across a range of neurodevelopmental conditions including ADHD, Autism Spectrum Disorder, Dyslexia and other learning disabilities, anxiety, and more.
Some diagnoses often assessed are as follows:
​
Autism Spectrum Disorder/Asperger’s Disorder (ASD)
​
​
Attention-Deficit/Hyperactivity Disorder (ADHD)
​
Major Depressive Disorder (MDD)
​
Early Childhood Evaluations
Dr. Hahn has expertise in evaluating preschool age children. She is an advocate for understanding a child's developing brain as early as possible to ensure the child receives appropriate services. Research has shown implementing interventions early in development produces the most positive outcomes versus the “wait and see” approach.
​
Autism Evaluations
Assessing for Autism requires specialized training given the nuances of signs and symptoms. Dr. Hahn believes strongly in not only relying on subjective measures such as questionnaires but also integrating objective tools to asses an individual’s cognitive, emotional, and social skills.
​
Independent Neuropsychological Evaluations (INE)
At times, school districts and parents may agree an INE is an appropriate next step to gathering information regarding a student’s cognitive, social and emotional strengths and areas of targeted growth. Dr. Hahn is known for providing an unbiased assessment of New Jersey school district students to assist with educational planning and academic placements.
