Why people come to us
When there are concerns about memory, attention, thinking, learning, or changes in cognitive functioning — and you need a clearer understanding of why.
A neuropsychological evaluation provides a detailed picture of cognitive strengths and difficulties. It can help clarify what is affected, how significantly it is affecting everyday functioning, possible reasons for those difficulties, and what steps may be helpful moving forward.
Memory
How new information is learned, retained, and retrieved over time — and which stage of that process is affected.
Attention
Sustained focus, divided attention, and the capacity to filter distraction across a working day.
Language
Word finding, comprehension, naming, and fluency in expression and understanding.
Executive functioning
Planning, organization, mental flexibility, judgment, and the regulation of behavior.
Processing speed
How quickly information is taken in and acted upon under everyday and timed conditions.
Visual-spatial skills
Perception, construction, and spatial reasoning, including navigation and visual organization.
Problem solving
Reasoning, abstraction, and the ability to work through unfamiliar situations methodically.
Emotional functioning
Mood, anxiety, and personality factors that can influence cognition and daily functioning.
