Our Clinical Services


Psychological evaluation services at IAN include comprehensive neuropsychological evaluations, behavioral assessments, cognitive and memory testing, personality assessment, and diagnostic clarifications.

Psychological testing provides an in-depth understanding of the relationship between the brain and our memory, thinking, and behavior. Individual testing allows us to assess cognitive processes such as concentration, planning and organization, reasoning, memory, language, personality, and coordination. Some of the most common conditions assessed include many different types of dementia, mild cognitive impairment, head injuries, learning disabilities, and developmental disorders. Testing allows us to determine the cause of one’s difficulties (i.e., processing speed or executive functioning deficits) and develop treatment recommendations to improve one’s quality of life and values.

Insurance Accepted: Blue Cross/Blue Shield, Medicare, Medicaid (pending)

What to Expect: Initial consultation, testing sessions (3-6 hours), and feedback session to review testing results.


(Brainwave Biofeedback) Neurofeedback is an advanced form of biofeedback that allows a client to see and train his/her brainwaves to cultivate efficient patterns of EEG activity. Since all behaviors, sensations, and emotions are based on brainwave functioning, neurofeedback training can help people learn to reduce stress and stress-related symptoms, regulate their emotions more effectively, improve their focus, concentration, and performance, and in many cases reduce or eliminate the need for medications for a variety of disorders. Neurofeedback is essentially a form of exercise for the brain that enhances the flexibility and stability of the EEG. If you’re interested in learning more about this service, we invite you to attend one of our free monthly talks or to schedule a personal consultation with one of our providers.

Interior Design for the Soul: Redecorate Your Inner Space

Your private, inner world is a virtual reality constructed from perceptions of yourself and your environment. In a well-intended effort to ensure survival, the human brain naturally emphasizes negative information in its awareness, frequently making one’s inner space a difficult place in which to live. Advances in neuroscience have confirmed what ancient wisdom traditions already knew - that specific skills are necessary to create a safe, supportive, and kind internal dwelling place. Doing so expands our emotional resiliency, better equipping us to maintain loving relationships and successfully navigate the challenges of the external world. Retreat participants will spend the weekend in the beautiful Blue Ridge Mountains, learning the neuroscience behind why these self-regulation strategies work, and have multiple opportunities to practice them with physiological feedback reflecting their progress.
