At NHG, we specialize in comprehensive neuropsychological evaluation and treatment of children and adults and provide both clinical and forensic services. We provide evidence-based assessments, drawing upon the latest discoveries in neuroscience, psychological theories, and educational research to create an effective and individually tailored treatment plan.

The evaluation is a pragmatic, interactive, and solution-focused process where individual cognitive strengths and weaknesses are identified for a detailed understanding of each person’s unique profile. Our approach is to provide diagnostic support and practical feedback to help patients resolve current difficulties. Our mission is to capitalize on personal strengths and empower each individual with the knowledge and tools needed to live a fulfilling and successful life.

Frequently Asked Questions

Q. What is neuropsychology?

A. Neuropsychology is the study of brain-behavior relationships. A clinical neuropsychologist is a psychologist with a doctorate degree and specialized training in how mood, behavior, and cognitive functions relate to brain structures and systems. While neuroimaging is essential to understanding the structural integrity of the brain, only neuropsychological assessment allows for an examination of the brain’s functionality in order to detect areas of cognitive strength and weakness. Neuropsychological assessment can determine if observed changes are age-appropriate variations, or a signal for some sort of pathology. 

Q. How long is the neuropsychological assessment and what can be expected afterward?

A. The neuropsychological assessment typically lasts between 6-8 hours, depending on the referral question. Testing sessions are usually extended over the course of 1-3 days in order to prevent fatigue which may interfere with performance. During the initial consultation appointment, the doctor will conduct an interview with the patient and family to review the patient’s history and discuss any questions that need to be addressed. Patients and/or family members may be asked to fill out questionnaires to provide invaluable information about the presenting concerns. The feedback session, typically scheduled 2 weeks following the initial meeting, will consist of an in-depth discussion detailing the testing results and the unique pattern of strengths and weakness of the patient. Diagnoses, treatment recommendations, and referrals are provided in feedback as well as documented in the report. 

At NHG, we have relationships with prominent providers of speech/language therapy, educational therapy, tutoring, executive coaching, occupational therapy, social work, psychiatry, neurology, pediatrics, genetic counseling, and legal advocacy and attorneys. Following the evaluation, your doctor will provide coordinated care to ensure the implementation of appropriate services, and will continue to be available for ongoing consultation.

Q. How will I (or my child) be assessed? 

A. Neuropsychological evaluation does not involve any poking, prodding, or needles! The evaluation will be comprised of computerized tasks, a verbally based question and answer format with the examiner, as well as written paper and pencil activities. Some tests will be timed while others will not, and the examinee is fully oriented to each new task as the testing progresses. Breaks are provided and often encouraged as we strive to assess your neuropsychological abilities in the most optimal conditions with time set aside for rest or snacks.

While it is a perfectly appropriate response, some children may feel slightly anxious during testing so please let your doctor know what reinforcers work best for your child to have prepared ahead of time (e.g., stickers, small prizes, or a favorite snack) in order to elicit their optimal motivation and attention. We aim to make the evaluation a fun, interactive, and above all an informative and pleasant experience for all.

Q. What will be assessed?

A. The nature of the evaluation will depend on the specific concerns to be addressed and the reason for referral, but may also include: 

Intellectual functioning | Academic achievement | Learning style | Attention and concentration | Processing speed  | Executive functioning  | Verbal and nonverbal reasoning  | Memory and learning  | Sensorimotor/fine motor functioning | Language abilities | Visuospatial skills | Personality and emotional functioning

Q. What can I expect on the evaluation day?

A. Please bring contacts, glasses, or assistive hearing devices you may need to your evaluation. A list of current medications as well as copies of any relevant medical records will be important to bring (e.g., MRIs, CT scans, previous neuropsychological testing reports, school records). It is recommended that the patient be best prepared with a restful night’s sleep, a healthy breakfast, and comfortable clothing on the day of the evaluation. Children should avoid consuming sugar-laden foods or caffeine on the day of testing. Adults should not consume alcohol or illicit substances 24 hours prior to your evaluation. It is advised to consult with your physician if you are currently taking any sleep or analgesic pain medication as it may interfere with your cognitive functioning on the testing day.
