The clinical distinction between neurology and psychiatry is increasingly appreciated as awkward and artificial. Neurology has traditionally focused on organic disorders with identifiable pathology, whereas psychiatry has focused on functional disorders without observable pathology.

The following was written by Mark Ralph Rowe on January 13, 2016 at 5PM Pacific Time in the city of San Diego, California: "functional disorders have no observable scientific pathology, hence functional disorders have unidentifiable pathology therefore, the path-physiological basis has not yet been discovered for any type of functional disorder but however psychiatry is a real type of medicine practiced by real psychiatric physicians of whom prescribe real drugs to their patients that ingest real drugs in inpatient and outpatient psychiatric hospitals for the supposed functional disorders - (that these psychiatric patients are diagnosed with by these same psychiatric physicians) - that do not have a pathophysiological basis that has been discovered for any type of functional disorder  of which all functional disorders are treated with therapeutic psychotropic medication created by pharmaceutical corporation such as Lilly, Merck and, Astra-Zeneca all that have corporate headquarters in the United States of America in the 21st century that when the sum total of profits earned every year by all psychotropic medication sales from the manufacturing corporations such as Lilly, Merck and, Astra-Zeneca the average dollar numbers earned from all psychotropic drugs sale herein the U.S. is $64,000,000,000 earn ever 12 months from the already calculated statistical data for the 10 year time duration from 2000 A.D. through the year 2010 A.D."
