Thanatology
Thanatology is the science that studies the events surrounding death, as well as the social, legal, and psychological aspects of death. The term thanatology originates from the Greek thanatos, meaning death and logos, for study or discourse. Thanatologists may study the cause of deaths, legal implications of death such as the rights and destiny of the remains or requirements for autopsy, and social aspects surrounding death. Grief, customs surrounding burial and remembrance, and other social attitudes about death are frequent subjects of interest for thanatologists.
From the forensic point of view, causes of death may be due to natural causes, such as from lethal
disease or advanced age), accidental causes, such as falls, plain crashes, fires, drowning, or automobile accidents, criminal actions, such as murder, neglect, malpractice, or other irresponsible acts by third parties, and finally, suicide. Thanatology also overlaps forensics when it focuses on the changes that occur in the body in the period near death and afterwards.
Some social issues explored by thanatologists, such as euthanasia (the merciful induction of death to stop suffering) and abortion (termination of a pregnancy) are subject to much ethical and legal controversy. These issues are legal in some countries, while considered a crime in other countries. In Brazil, for instance, although outright euthanasia is illegal, patients have the right to refuse medical treatment and artificial life supporting procedures, if they sign a legal statement in advance while of sound mind.
Rights over the corpse of the deceased is also determined by law in most developed countries, as well as burial, cremation, and embalming requirements. Clinical autopsies are generally required in cases of unexplained or violent death, suspicion of suicide, drug overdose, or when requested by the family of the deceased due to suspicion of medical error or when confirmation of certain diseases is sought.
The thanatology community is usually composed of a variety of health professionals including psychiatrists and other physicians such as forensic pathologists, advanced practice nurses, and veterinarians, along with sociologists and psychologists.
