Adult Neuropsychology

Adult Neuropsychology -



The Stixrud Group serves adults of all ages. Our staff includes the Director, Dr. Robb Mapou; Dr. Wendy Law, who has been with the practice since 1996; and Dr. Salya Namazi, who rejoined the Group in 2014 after completing her doctoral degree. She had previously worked with us for two years as a Psychology Associate. You can click on each person’s name or go directly to our Staff page for their biographies. We routinely evaluate adults with complex diagnostic issues that may date to childhood (developmental) or that may be new. There are various reasons why you may want a neuropsychological evaluation. Some types of problems for which adults see us include:

  • Memory problems
  • Problems with attention and concentration
  • Difficulty with organization, time management, and work completion
  • Difficulty with reading, writing, or math
  • Difficulty succeeding in school
  • Difficulty establishing independence as a young adult

The causes of these problems can include, but are not limited to:

  • Normal aging
  • Learning disabilities
  • Attention-deficit/hyperactivity disorder [ADHD]
  • Autism-spectrum disorders
  • Other disorders starting in childhood
  • Traumatic brain injury (mild [concussion] to severe)
  • Seizure disorders (Epilepsy)
  • Other brain disorders
  • Dementia
  • Psychiatric and psychological disorders
  • Genetic disorders that can affect the brain
  • Sleep disorders
  • Health conditions that can affect the brain

Our neuropsychological evaluations are always determined by a client’s needs and particular problems. Our Clinical Care Managers will often consult with our neuropsychologists, to determine what type of evaluation is needed. These evaluations include:

  • A comprehensive evaluation, typically used when individuals are seen for the first time, have a need for a very detailed report for academic accommodations, or prefer this level of evaluation.
  • A differential diagnostic evaluation, typically used to sort out what is going on with the person and to make recommendations. Academic testing may be limited or not included at all, and the report is shorter.
  • Consultations, which are much briefer and typically involve an interview, completion of rating scales, review of records, and, sometimes, a test of attention and a personality measure. These are often best for individuals who wonder if they have ADHD, who have had a concussion but are not recovering as expected, or who have had a comprehensive assessment and would like a neuropsychologist to review what was done. Some adults will go on to complete a longer neuropsychological evaluation, if the neuropsychologist believes that would be helpful.

We also have three types of specialized evaluations:

  • Federal Aviation Administration (FAA) neuropsychological evaluations, including Cogscreen, needed for medical certification or recertification.
  • Medico-legal evaluations, typically done for an attorney and in the context of a legal case. These cases are always reviewed with the attorney first, before they are accepted, to be sure that the neuropsychologist can serve the client in the best way.
  • Independent medical evaluations, typically completed at the request of a disability insurance company, to determine a client’s level of disability and treatment needs.
