Medication, psychotherapy, neurofeedback…. How do I know what is the right treatment for me?

For Sadar Psychological, the most important thing is the quality of life and functionality of our patients. We use scientifically based methods to measure, analyze and understand your brain’s functioning, to help develop a plan to maximize treatments and life style changes to help you feel and function your best.

Understanding your brain is a collaborative work with researchers at Harvard University in the Neuromodulation Laboratory at Spaulding Rehabilitation Hospital in Boston with the aim of directing you to the the most advanced treatments in neuro-rehabilitation. Our partnership with HBIMed in Switzerland allows us to base our evaluations on the latest research available.

Understand your brain.

We are here to help you have hope and feel better.

Most people want to know about certain conditions, such as ADHD, Anxiety, Chronic Pain, Depression, etc. However, these “conditions” are names given to behavior without assessing how the brain is making the behavior.

We want to get to the root of your concerns, so the most personalized treatment can be recommended to expedite your path to feeling your best!
