This is a timeline of the history of medicine and medical technology.
Hematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, sickle cell anemia, blood clots (thrombus), other bleeding disorders, and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory analysis of blood is frequently performed by a medical technologist or medical laboratory scientist.
Historically, mental disorders have had three major explanations, namely, the supernatural, biological and psychological models. For much of recorded history, deviant behavior has been considered supernatural and a reflection of the battle between good and evil. When confronted with unexplainable, irrational behavior and by suffering and upheaval, people have perceived evil. In fact, in the Persian Empire from 550 to 330 B.C., all physical and mental disorders were considered the work of the devil. Physical causes of mental disorders have been sought in history. Hippocrates was important in this tradition as he identified syphilis as a disease and was, therefore, an early proponent of the idea that psychological disorders are biologically caused. This was a precursor to modern psycho-social treatment approaches to the causation of psychopathology, with the focus on psychological, social and cultural factors. Well known philosophers like Plato, Aristotle, etc., wrote about the importance of fantasies, dreams, and thus anticipated, to some extent, the fields of psychoanalytic thought and cognitive science that were later developed. They were also some of the first to advocate for humane and responsible care for individuals with psychological disturbances.
In the Middle Ages, the medicine of Western Europe was composed of a mixture of existing ideas from antiquity. In the Early Middle Ages, following the fall of the Western Roman Empire, standard medical knowledge was based chiefly upon surviving Greek and Roman texts, preserved in monasteries and elsewhere. Medieval medicine is widely misunderstood, thought of as a uniform attitude composed of placing hopes in the church and God to heal all sicknesses, while sickness itself exists as a product of destiny, sin, and astral influences as physical causes. On the other hand, medieval medicine, especially in the second half of the medieval period, became a formal body of theoretical knowledge and was institutionalized in the universities. Medieval medicine attributed illnesses, and disease, not to sinful behavior, but to natural causes, and sin was connected to illness only in a more general sense of the view that disease manifested in humanity as a result of its fallen state from God. Medieval medicine also recognized that illnesses spread from person to person, that certain lifestyles may cause ill health, and some people have a greater predisposition towards bad health than others.
The Hippocratic Corpus, or Hippocratic Collection, is a collection of around 60 early Ancient Greek medical works strongly associated with the physician Hippocrates and his teachings. The Hippocratic Corpus covers many diverse aspects of medicine, from Hippocrates' medical theories to what he devised to be ethical means of medical practice, to addressing various illnesses. Even though it is considered a singular corpus that represents Hippocratic medicine, they vary in content, age, style, methods, and views practiced; therefore, authorship is largely unknown. Hippocrates began Western society's development of medicine, through a delicate blending of the art of healing and scientific observations. What Hippocrates was sharing from within his collection of works was not only how to identify symptoms of disease and proper diagnostic practices, but more essentially, he was alluding to his personable form of art, "The art of true living and the art of fine medicine combined." The Hippocratic Corpus became the foundation upon which Western medical practice was built.
Cognitive disorders (CDs), also known as neurocognitive disorders (NCDs), are a category of mental health disorders that primarily affect cognitive abilities including learning, memory, perception, and problem-solving. Neurocognitive disorders include delirium, mild neurocognitive disorders, and major neurocognitive disorder. They are defined by deficits in cognitive ability that are acquired, typically represent decline, and may have an underlying brain pathology. The DSM-5 defines six key domains of cognitive function: executive function, learning and memory, perceptual-motor function, language, complex attention, and social cognition.
Aulus Cornelius Celsus was a Roman encyclopaedist, known for his extant medical work, De Medicina, which is believed to be the only surviving section of a much larger encyclopedia. The De Medicina is a primary source on diet, pharmacy, surgery and related fields, and it is one of the best sources concerning medical knowledge in the Roman world. The lost portions of his encyclopedia likely included volumes on agriculture, law, rhetoric, and military arts. He made contributions to the classification of human skin disorders in dermatology, such as myrmecia, and his name is often found in medical terminology regarding the skin, e.g., kerion celsi and area celsi. He is also the namesake of Paracelsus, a great Swiss alchemist and physician prevalent in the Medical Renaissance.
Aretaeus is one of the most celebrated of the ancient Greek physicians. Little is known of his life. He presumably was a native or at least a citizen of Cappadocia, a Roman province in Asia Minor, and most likely lived in the second half of the second century AD. He is generally styled "the Cappadocian" (Καππάδοξ).
Girolamo Mercuriale or Mercuriali was an Italian philologist and physician, most famous for his work De Arte Gymnastica.
Organic brain syndrome, also known as organic brain disease, organic brain damage, organic brain disorder, organic mental syndrome, or organic mental disorder, refers to any syndrome or disorder of mental function whose cause is alleged to be known as organic (physiologic) rather than purely of the mind. These names are older and nearly obsolete general terms from psychiatry, referring to many physical disorders that cause impaired mental function. They are meant to exclude psychiatric disorders. Originally, the term was created to distinguish physical causes of mental impairment from psychiatric disorders, but during the era when this distinction was drawn, not enough was known about brain science for this cause-based classification to be more than educated guesswork labeled with misplaced certainty, which is why it has been deemphasized in current medicine. While mental or behavioural abnormalities related to the dysfunction can be permanent, treating the disease early may prevent permanent damage in addition to fully restoring mental functions. An organic cause to brain dysfunction is suspected when there is no indication of a clearly defined psychiatric or "inorganic" cause, such as a mood disorder.
Ancient Greek medicine was a compilation of theories and practices that were constantly expanding through new ideologies and trials. The Greek term for medicine was iatrikē. Many components were considered in ancient Greek medicine, intertwining the spiritual with the physical. Specifically, the ancient Greeks believed health was affected by the humors, geographic location, social class, diet, trauma, beliefs, and mindset. Early on the ancient Greeks believed that illnesses were "divine punishments" and that healing was a "gift from the Gods". As trials continued wherein theories were tested against symptoms and results, the pure spiritual beliefs regarding "punishments" and "gifts" were replaced with a foundation based in the physical, i.e., cause and effect.
Fasciculus Medicinae is a "bundle" of six independent and quite different medieval medical treatises. The collection, which existed only in two manuscripts, was first printed in 1491 in Latin and came out in numerous editions over the next 25 years. Johannes de Ketham, the German physician routinely associated with the Fasciculus, was neither the author nor even the original compiler but merely an owner of one of the manuscripts. The topics of the treatises cover a wide spectrum of medieval European medical knowledge and technique, including uroscopy, astrology, bloodletting, the treatment of wounds, plague, anatomical dissection, and women’s health. The book is remarkable as the first illustrated medical work to appear in print; notable illustrations include: a urine chart, a diagram of the veins for phlebotomy, a pregnant woman, Wound Man, Disease Man and Zodiac Man. In 1495, it appeared in Italian under the title Fasiculo de Medicina.
Medicine in ancient Rome was highly influenced by ancient Greek medicine, but also developed new practices through knowledge of the Hippocratic Corpus combined with use of the treatment of diet, regimen, along with surgical procedures. This was most notably seen through the works of two of the prominent Greek physicians, Dioscorides and Galen, who practiced medicine and recorded their discoveries. This is contrary to two other physicians like Soranus of Ephesus and Asclepiades of Bithynia, who practiced medicine both in outside territories and in ancient Roman territory, subsequently. Dioscorides was a Roman army physician, Soranus was a representative for the Methodic school of medicine, Galen performed public demonstrations, and Asclepiades was a leading Roman physician. These four physicians all had knowledge of medicine, ailments, and treatments that were healing, long lasting and influential to human history.
The following outline is provided as an overview of and topical guide to medicine:
The Medicina Plinii or Medical Pliny is an anonymous Latin compilation of medical remedies dating to the early 4th century AD. The excerptor, saying that he speaks from experience, offers the work as a compact resource for travelers in dealing with hucksters who sell worthless drugs at exorbitant prices or with know-nothings only interested in profit. The material is presented in three books in the conventional order a capite ad calcem, the first dealing with treatments pertaining to the head and throat, the second the torso and lower extremities, and the third systemic ailments, skin diseases, and poisons.
The history of dermatology concerns the development of the practice of researching, defining and treating skin diseases, from ancient times to the present. The field has its origin in the earliest forms of medicine, later becoming a distinct field with its own specialised practitioners and researchers.
Trota of Salerno was a medical practitioner and writer in the southern Italian coastal town of Salerno who lived in the early or middle decades of the 12th century. Her fame spread as far as France and England in the 12th and 13th centuries. A Latin text that gathered some of her therapies was incorporated into an ensemble of treatises on women's medicine that came to be known as the Trotula, "the little book [called] 'Trotula'". Gradually, readers became unaware that this was the work of three different authors. They were also unaware of name of the historical writer, which was "Trota" and not "Trotula". The latter was thenceforth misunderstood as the author of the whole compendium. These misconceptions about the author of Trotula contributed to the erasure or modification of her name, gender, level of education, medical knowledge, or the time period in which the texts were written; this trend often resulted from the biases of later scholars. Trota's authentic work was forgotten until it was rediscovered in the late 20th century.
Mental illness in ancient Rome was recognized in law as an issue of mental competence, and was diagnosed and treated in terms of ancient medical knowledge and philosophy, primarily Greek in origin, while at the same time popularly thought to have been caused by divine punishment, demonic spirits, or curses. Physicians and medical writers of the Roman world observed patients with conditions similar to anxiety disorders, mood disorders, dyslexia, schizophrenia, and speech disorders, among others, and assessed symptoms and risk factors for mood disorders as owing to alcohol abuse, aggression, and extreme emotions. It can be difficult to apply modern labels such as schizophrenia accurately to conditions described in ancient medical writings and other literature, which may for instance be referring instead to mania.
Ancient Roman surgical practices developed from Greek techniques. Roman surgeons and doctors usually learned through apprenticeships or studying. Ancient Roman doctors such as Galen and Celsus described Roman surgical techniques in their medical literature, such as De Medicina. These methods encompassed modern oral surgery, cosmetic surgery, sutures, ligatures, amputations, tonsillectomies, mastectomies, cataract surgeries, lithotomies, hernia repair, gynecology, neurosurgery, and others. Surgery was a rare practice, as it was dangerous and often had fatal results. To perform these procedures, they used tools such as specula, catheters, enemas, bone levers, osteotomes, phlebotomes, probes, curettes, bone drills, bone forceps, cupping vessels, knives, scalpels, scissors, and spathas.
Modern historians' knowledge of ancient Roman gynecology and obstetrics primarily comes from Soranus of Ephesus' four-volume treatise on gynecology. His writings covered medical conditions such as uterine prolapse and cancer and treatments involving materials such as herbs and tools such as pessaries. Ancient Roman doctors believed that menstruation was designed to rid the female body of excess fluids. They believed that menstrual blood had special powers. Roman doctors may also have noticed conditions such as premenstrual syndrome.
