Medicolegal Neuropsychological Evaluations in St. Charles, IL
When a legal question depends on how a person thinks, remembers, or makes decisions, an objective neuropsychological evaluation can provide clear, defensible answers. Hesed Psychological Services provides medicolegal neuropsychological evaluations from our St. Charles office for attorneys, fiduciaries, claims professionals, referring physicians, and individuals across Chicagoland, including Kane and DuPage Counties.
Evaluations we provide
Capacity and competency: decision-making capacity for medical and legal matters
Brain injury and medical conditions: cognitive and emotional effects of traumatic brain injury (TBI) and other injuries or neurological conditions
Return to work: whether cognitive or emotional changes affect a person's ability to resume their job
Disability: the level of impairment related to a neuropsychological condition
Depositions and testimony: clear explanations of test findings for attorneys, judges, and juries
Why neuropsychological data matters in legal cases
Many legal questions come down to specific thinking abilities: memory, attention, reasoning, language, and judgment. A neuropsychological evaluation measures those abilities with standardized tests and compares the results with people of the same age. It also uses measures of performance and symptom validity, so the findings rest on objective data rather than impressions alone.
Led by a fellowship-trained clinical neuropsychologist
Evaluations are led by Dr. Benjamin Pyykkonen, PhD, a licensed clinical psychologist and fellowship-trained clinical neuropsychologist with 20 years of experience. He earned his PhD at Illinois Institute of Technology, completed his fellowship at Rush, and has directed a doctoral program at Wheaton College. His research includes performance validity, traumatic brain injury, dementia, epilepsy, stroke, cancer, and cancer treatments. It has appeared in journals including Frontiers in Neurology, the Journal of the International Neuropsychological Society, and the Journal of the Alzheimer's Association.
