Professor Vernon M Neppe MD, PhD (Med), FRSSAf, DFAPA, FFPsych (SA), MMed (Psych), ABPN (BC Psychiatry' subspecialties: Forensic Psychiatry -04, Geriatric Psychiatry-11), DPsM (with Neurology / Psychiatry), DSPE, DABFM, DABFE, DABPS (Psychopharmacology), FACFE, LMACFE, FCPsych, MB, BCh,, BA, FRCPC-10, MMed, is a formidable, highly trained, experienced and internationally renowned neuropsychiatrist, behavioral neurologist, psychopharmacologist, psychiatrist, epileptologist, consciousness researcher, in-demand communicator, civil forensic expert (defense or plaintiff), peer-respected clinician, extensively published academic, book-author and incisive thinker. Applying several objective criteria (peer-review and recognition,, training, experience, results, versatility), Dr Neppe is one of the most highly qualified medical experts in the USA, and uniquely qualified in his broad areas of testimony. He prefers civil medicolegal expert work, attempting to equalize defense and plaintiff cases, but will occasionally accept competency cases. His multiple specialties and qualifications allow him to be retained as a single expert performing tasks that often require numerous experts. He is very strong as a clinician and researcher and demonstrates powerful intangibles in forensic research (incisive thinker, professional communicator, excellent research methodologist, clinical scientist, writer —very useful for declarations, and MD and PhD). This allows Professor Neppe to at times double up on as a an expert in many different disciplines.

• Dr. Neppe was recruited after an international search to establish and become Director of what was then apparently the first Division of Neuropsychiatry in a Department of Psychiatry in the USA (in 1986, at the University of Washington, Seattle)
• In August 1992, he then established a model neuropsychiatric institute, the Pacific Neuropsychiatric Institute in Seattle, for complex clinical evaluations and also performs a limited number of  forensic evaluations.
• He also has a PhD and so is an MD, PhD. This increases his versatility as an expert and has led to his great expertise in Research Methodology allowing the skill of approaching medical and psychological data carefully and critically.
• He has over time been awarded numerous specialist qualifications making him academically one of the most highly trained physicians in the United States. MD, PhD(Med), FRSSAf, DFAPA, FFPsych(SA), FRCPC, MMed (Psych), DipABPN [Psychiatry; Geriatric Psychiatry; Forensic Psychiatry' BN&NP, DABFM, DABFE, DABPS (Psychopharmacology), FACFE, LMACFE, MB, BCh, DPsM , BA). On paper, this makes Dr Neppe one of the most highly qualified physicians in his area in the world. He has USA board certifications as well as numerous non-USA specialist qualifications.
  • He was the first USA physician to be elected to the prestigious position of Fellow of the Royal Society (South Africa).
  • He was recognized as a Distinguished Fellow of the American Psychiatric Association (highest public level).
  • He was in the first batch of board certified physicians under the United Council for Neurological Subspecialties being certified in Behavioral Neurology and Neuropsychiatry.
  • He led the first US and International Delegation in Neuropsychiatry and Psychopharmacology, and was chosen to lead the first such delegation in Behavioral Neurology and Neuropharmacology.
  • He was recognized by the CINP as one of the Leading Psychopharmacologists of the Twentieth Century.
  • He established the first Division of Neuropsychiatry in a Psychiatry Department in the USA.
  • His exceptional creativity across several different areas is demonstrated objectively by his being the only Distinguished Professor or the Exceptional Creative Achievement Organization.
• He has been working in this field of Forensic Psychiatry/ Neuropsychiatry/ Psychopharmacology for more than three decades. In the specific context of his Medicolegal work, Dr Vernon Neppe became certified in Forensic Psychiatry in their very first examination by the American Board of Forensic Psychiatry in 1994 (-2004). He is also a Member of AAPL (the American Association for Psychiatry and the Law).
• He has been regarded by his peers as a leading expert in his area: For example, he appears in every edition to date of America's Top Doctors, and is apparently the only MD ever listed under any five different specialties or subspecialties. In Dr Neppe's instance this is Neuropsychiatry, Behavioral Neurology, Psychopharmacology, Psychiatry and  Forensic Neuropsychiatry. America's Top Doctors is a peer voted primary source for such information and he is in all 13 editions.
Moreover, Dr Neppe was apparently also listed in all editions of the peer voted on book, 
Best Doctors in America, when it was the authority in the mid/late 1990s.
• He is an academic as well —an Adjunct Full Professor, Department  of Neurology and Psychiatry, in St Louis, 1700 miles from his home base, a singular honor, attesting to his degree of respect (an extremely unusual honor). He keeps up-to-date on the standard texts, controversies and trends in his field as well as with clinical changes.
• He is author of two books on psychopharmacology and has made ground-breaking contributions to the area. He has written 10+books and is very extensively published.
• He has developed several measuring and other neuropsychiatric tests and pioneered the area of neuropsychiatry.
• He was instrumental in the American Medical Association listing a subspecialty of neuropsychiatry under psychiatry.
• He was 
also a consultant for DSM 3, 4, 4R and 4TR.
• He also has been recognized as the pioneer of several major areas of research in psychopharmacology, such as the use of anticonvulsants in psychiatry and developing a treatment for tardive dyskinesia.
He has similarly made pioneering contributions in Neuropsychiatry and Behavioral Neurology in developing tests, new terms, new classifications and describing new conditions.


Given Dr Neppe's prime leadership position, pioneering as he has higher brain functions and traumatic brain injury, a recent topically important, high profile area that Dr Neppe is now forensically consulting in is Chronic traumatic encephalopathy.

His major areas of expertise include multiple areas where he is an international authority on numerous related areas, using a criterion based on publications, presentations, research or recognitions:

1. Head trauma / brain injury / cerebral disturbances/ head injury (e.g., key chapters in books; own published classification of closed head injuries, plus medicolegal consultations including 8-figure settlement), 
2. Side-effects and clinical impacts of brain medications (e.g. author of two books on psychopharmacology; extensive publications plus medicolegal consultations),
3. Seizures and atypical spells (extensive background; publications; pioneering discoveries; measuring instrument; classification plus medicolegal consultations),
4. Tardive dyskinesia, neuropharmacology of basal ganglia disorders (such as Parkinson's syndromes) (e.g. plus medicolegal consultations and key publications).
5. Neuroleptic malignant syndrome (e.g. published review, pioneering discovery plus medicolegal consultations),
6. Attention deficit (e.g. pioneering discovery, treatment published plus medicolegal consultations; far more than Attention Deficit Disorder),
7. Mental status (a leading authority plus medicolegal consultations),
8. Narcolepsy (developed questionnaire and delivered inaugural invited address to Division of Chronobiology at Cornell University),
9. Vegetative states and minimally conscious states (published on special evaluation skills in persistent vegetative states and minimally conscious states (expert consultant in a major 8-figure settlement),
10. Organic and psychiatric aspects of brain and biological conditions. (e.g. consultancies to DSM-IVR; publications and medicolegal consultations)
11. Pharmaceutical patents (retained by attorneys for both brand name and generic companies plus published in generic/ brand drugs),
12. Nutraceuticals, nutritional supplements (major interest e.g., writing a book on dietary supplements and developed a special document on the hazards for the ASCP) on obesity (including psychotropic medication side-effects, lectured nationally) and diet (currently, writing a book on the subject) and on previously used diet compounds such as Ephedra alkaloids (both plaintiff and defense expert).
13. Suicide and depression, anxiety, and aggression (retained by both defense and plaintiff; extensive expertise in area with publications).
14. Medical malpractice (within expertise and writings and retained by both defense and plaintiff; see too How Attorneys Can Best Utilize Their Medical Expert Consultant: A Medical Expert’s Perspective)
15. HIPAA and related security internet issues (publications),
16. Chemical sensitivities, prolonged. (e.g.’s-Disability-Award),
17. Carbon monoxide and brain injury (medicolegal consultations for neuropsychiatric expertise on carbon monoxide's effects on the brain),
18. Personal injury (within expertise and writings and retained by both defense and plaintiff; see too How Attorneys Can Best Utilize Their Medical Expert Consultant: A Medical Expert’s Perspective)
19. Competency issues provided these are not associated with criminal cases . (Developed evaluations of higher brain function with mental status; plus medicolegal consultations).
20. Disability. e.g. again’s-Disability-Award, where comprehensive reports are written.
21. Wrongful death  (medicolegal consultations).

These skills allow Dr. Neppe to be a very powerful expert for many different kinds of cases, including personal injury, malpractice and competency issues. Moreover, his potential use in multiple capacities, such as Neuropsychiatry and Behavioral Neurology and Psychopharmacology as well as Psychiatry and Seizure phenomena, and as an expert on higher brain functioning, and his combined MD and PhD qualifications, and extensive publications in many areas, markedly increase his versatility and range as an expert consultant. This should permit the retaining of fewer experts in certain cases, and allows for powerful rebuttals and more complete perspectives in consultations.

Dr. Neppe's passion for supporting the finest achievements in medico-legal forensic work has led him to write an excellent and informative book, designed to give any attorney the inside view of how to best utilize a medical expert witness:

How Attorneys Can Best Utilize Their Medical Expert Consultant: A Medical Expert’s Perspective  (2nd edition, ).

Nationally respected medico-legal expert, Vernon M Neppe MD, PhD has put his many years of experience as an expert medico-legal consultant in complex forensic neuropsychiatric and psychopharmacological cases to good use: He has drawn upon his singular expertise to put together this detailed guide for the attorney as well as for fellow medical experts. The many layers of this monograph are all directed toward one aim—winning the case. In his new book, How Attorneys Can Best Utilize Their Medical Expert Consultant: A Medical Expert’s Perspective, Dr Neppe balances the importance of the medical expert’s integrity, which places limits on his or her testimony, with the needs of the attorney in pursuing the legitimate objective of successful litigation. This balance which Dr Neppe achieves harnesses the best of both worlds of Law and Medicine: the professional integrity of the medical expert, while limiting the utilized testimony, at the same time endows it with unimpeachable effectiveness for use by the attorney as long as its limitations are understood and targeted. Dr Neppe succeeds in analyzing and presenting the dynamics of this balance in a format that is at once clear and elegant yet sacrifices none of the potential complexities of that necessary partnership between attorney and medical expert.
This monograph/e-book may assist attorneys in their choice of medical expert witnesses.
