Neuropsychology involves the assessment of cognition and behavior in people with known, suspected or disputed abnormalities in brain function. A referral from your primary care physician, pediatrician, neurologist or other medical professional is typically required if you want to utilize Mary Free Bed’s outpatient neuropsychology services.

Through interviews, observation and a series of tests that evaluate attention levels, memory, mood and other mental functions, the neuropsychologists at Mary Free Bed will work to determine the presence and nature of abnormal brain function and will assist with treatment planning.

Mary Free Bed employs several neuropsychologists. Doctors Jacobus Donders and Kate Wilson are both board-certified in clinical neuropsychology through the American Board of Professional Psychology.

Mary Free Bed offers brief neuropsychological screenings and comprehensive neuropsychological assessments. We also provide follow-up treatment, including behavioral management consultations and psychotherapy.




A neuropsychological evaluation involves an interview, observation and various tests with a psychologist who has special expertise in the relationship between the brain and various aspects of human behavior. The goal is to develop an understanding of why your brain might not be functioning in a normal and healthy way and what needs to be done to improve your brain function.

The psychologist may recommend certain types of therapy, but those will most likely need to be approved first by your own doctor and/or your insurance company. Often, the evaluation can help your doctor decide what kind of treatment is needed.

The majority of the neuropsychological evaluations at Mary Free Bed Rehabilitation Hospital are done at the request of physicians or other service providers. A much smaller number are independent medicolegal evaluations (IMEs), which typically are completed at the request of a lawyer, claims adjuster or other person involved in a case where there is disagreement about the nature or cause of the problem. Under those conditions, the psychologist performing an IME has agreed to do a one-time evaluation and will not continue as your treating doctor.

Below are questions we hear from patients and their families who are interested in learning more about our neuropsychology services.

Frequently Asked Questions

How long will the evaluation take and who should attend?
Plan on the evaluation taking a full morning and most of the afternoon. A typical evaluation is at least six hours. The neuropsychologist may find it helpful to talk to your spouse or adult children as part of the evaluation process. This will only be done with your permission.

If the evaluation is for your child, the length may vary depending on the child’s specific needs. For children under the age of 18, a custodial parent is required to sign forms and participate in part of the interview. The parent, or an adult designee, should stay on the premises while the child is being evaluated.

No one other than the patient and the psychologist will be allowed in the room during the formal testing. Exceptions may be made for very young children or very unusual circumstances, at the sole discretion of the psychologist.

How will I learn about the results?
The neuropsychologist will schedule a time to go over the results with you. Typically, these are available the same day but always within three working days.

The person who referred you, most often your physician, will receive a formal report within 10 working days. You may also request, in writing, that the report be sent to others, such as doctors or a school principal.

The only circumstances in which the psychologist cannot give you information about the results is when the evaluation is done as part of an independent medicolegal evaluation (IME), which is typically done at the request of a lawyer, claims adjuster or other person involved in a case where there is disagreement about the nature or cause of the problem.

What if I need to cancel my neuropsychological appointment?
Please call us at least 24 hours in advance if you need to cancel your neuropsychological appointment for any reason. If you fail to show for your appointment or do not give at least 24 hours of notice on two consecutive occasions, the psychologist will not agree to reschedule.
