About Lanier Rossignol, BSN FNP-C

Lanier Rossignol, BSN FNP-C is a certified family nurse practitioner. She received her graduate training as a Family Nurse Practitioner and her Master’s Degree in Nursing from the University of Virginia. She also has a Bachelor of Arts in Neurobiochemistry and a Bachelor of Science in Nursing from the University of Virginia. After her two sons were diagnosed with autism, she sought information from a number of sources including researchers, specialists, the medical literature, and she attended 6-8 autism medical conferences per year to help find answers for her sons. As biomedically-based treatments helped her sons begin speaking, she became more involved in research in autism. After years of focusing on both her sons and her own medical issues, she has now joined her husband, Dr. Rossignol, and his medical practice as a Nurse Practitioner to help families struggling with the underlying medical issues of autism.  

 

Lanier has a special interest in autism spectrum disorders, PANS/PANDAS, chronic fatigue, and health and wellness through diet, supplements and exercise. Lanier is seeing patients in our Aliso Viejo office.

Not just medicine - It's about caring and helping you and your child

Caring for medically complex children and adults is, obviously, complex.  There are no “cookie cutter” templates that can be followed that will work consistently for all individuals.  Each individual possesses a unique medical puzzle.  That is why Dr. Rossignol treats each person individually, providing care with one goal in mind – to unlock this puzzle and allow each individual to thrive.

Identifying the biochemical fingerprint of autism: Implications for testing and treatments

Accumulating evidence has demonstrated that autism is sometimes characterized by complex abnormalities such as oxidative stress, mitochondrial dysfunction, inflammation, certain genetic abnormalities, exposure(s) to environmental toxicants, immunological abnormalities, infections, and in some cases, developmental regression and seizures. These abnormalities may contribute to the symptoms of autism, such as sleep problems, obsessive behavior, speech delay, impaired social interaction, self-stimulatory behavior, hyperactivity, inattention, and abnormal gastrointestinal findings.  Many children with autism have a unique combination of these abnormalities and may possess some or all of these problems simultaneously.  The early identification of these abnormalities may help clinicians and parents choose more effective treatment options.  Dr. Rossignol’s aim is to identify the unique biochemical abnormalities that each individual possesses (e.g., the biochemical fingerprint) and work to create the most effective treatments for these abnormalities using evidence-based medicine principles.  See a list of publications by Dr. Rossignol which discuss many of these abnormalities and potential treatments.
