Great Lakes Neurobehavioral Center (GLNC) provides comprehensive neuropsychological and psychological assessment, as well as, interventions to assist parents and families to understand a child’s strengths and challenges. At GLNC we offer evidence based psychological and neuropsychological services to develop skills and provide supports for greater success in the lives of children.



Clinicians at the GLNC utilize a multi-layered approach to evaluate the child’s cognitive, neurobehavioral, emotional, and individual skills as they contribute to a better understanding of the child’s functioning.

About Neuropsychology

Pediatric neuropsychology is a specialty concerned with learning and behavior in relation to a child’s brain. A pediatric neuropsychologist is a licensed psychologist with expertise in how learning and behavior are associated with the development of brain structures
and systems.

Neuropsychological evaluations are conducted to diagnose learning or behavior disorders caused by altered brain function or development. Neuropsychology services at Great Lakes Neurobehavioral Center are available to individuals ages 1 to young adulthood.

Benefits of an Evaluation

Neuropsychological evaluations assist in better understanding a child’s functioning in areas such as memory, attention, perception, coordination, language, and personality. Gaining insight in these areas helps the child’s parents, teachers, therapists, and physicians provide treatments/interventions to meet the child’s unique needs.

Neuropsychology services are recommended when
a child has:

  • Difficulty with learning, attention, memory, or communication
  • Difficulty with behavior, socialization, or emotional control
  • Disease or inborn developmental problem that affects the brain
  • Brain injury from an accident, birth trauma, or prematurity
  • Conditions or complications such as:
    Epilepsy/Seizures, ADHD, Concussion/Brain Injury, Fetal Alcohol Spectrum Disorder, Learning Disability, Prematurity/Low, Birth Weight, Cancer/Brain Tumors, History of Organ Transplant, Emotional Difficulties, Autism Spectrum Disorders, and Tic Disorders

What to Expect

The psychologist will meet with the child and caregiver(s). Then the child will spend much of the day with the psychologist completing various evaluation activities, for example, solving puzzles, listening and remembering information, using their hands to construct things or draw pictures, and possibly working on a computer.

Caregivers are a vital part of the assessment team in providing information, history and current concerns. In addition to meeting together, caregivers will be interviewed without the child present on the day of the evaluation. At the conclusion of the evaluation, feedback regarding the evaluation results and diagnostic impressions are provided.

Intervention recommendations are provided to better understand and manage challenging behaviors that impact all aspects of the child’s life. These recommendations may impact medical, educational, or social functioning, and provide links to resources to make informed decisions.


GLNC provides therapy services to address emotional and behavioral issues, as well as psychological aspects of chronic or acute illness, injury and health-related behaviors.

These services focus on issues such as:

  • Developing adherence plans for chronic conditions.
  • Promoting proper health behaviors for conditions such as chronic or recurrent pain, carrying excess weight, enuresis, encopresis, and others.

Pediatric neuropsychology is a specialty concerned with learning and behavior in relation to a child’s brain. A pediatric neuropsychologist is a licensed psychologist with expertise in how learning and behavior are associated with the development of brain structures and systems.

Neuropsychological evaluations are conducted to diagnose learning or behavior disorders caused by altered brain function or development. Neuropsychology services at Great Lakes Neurobehavioral Center are available to individuals ages 1-18.

Neuropsychological evaluations assist in better understanding a child’s functioning in areas such as memory, attention, perception, coordination, language, and personality. Gaining insight in these areas helps the child’s parents, teachers, therapists, and physicians provide treatments/ interventions that will meet the child’s unique needs. Neuropsychology services are recommended when a child has:

  1. Difficulty with: Learning, attention, behavior, socialization, and emotional control
  2. Disease or inborn developmental problem that affects the brain in some way
  3. A brain injury from an accident, birth trauma, or prematurity

The neuropsychologist will speak to one or both parents as the child begins testing. Since consent or release of information forms may need to be signed, make sure that the person accompanying your child has the legal authority to do this. Step-parents or relatives who do not have legal custody or guardianship cannot give permission for testing or sign legal documents.

Depending on the age of the child and the reason for testing, most neuropsychological testing appointments last either the entire morning or entire afternoon. The neuropsychologist will be able to give you a rough estimate of time involved after discussing your child’s specific needs with you. Time actually taken will depend on your child’s rate of responding as well as your child’s need for breaks.

Most children think that visiting a doctor means they will get a shot. Let them know no shots are given in neuropsychology. Let them know why they are coming in for testing. You can describe it as a lot like school. They will be doing activities that involve listening, remembering, using their hands to construct things or draw pictures, solving puzzles, and possibly working on a computer. Tell them they will be given breaks to use the bathroom, and snacks you bring if they get hungry. Let your child know you will be waiting close by while they work along with the neuropsychologist.
