I would like to know what are the similarities and de similarities in BRAIN STEM DEATH AND BRAIN DEATH.
Greetings!
For Goila & Parwa (2009) brain stem death, is declared in the wake of a loss of electrical activity, to that portion of the brain. Brain death is extensive brain damage. Extensive brain damage must be validated by other objective measures, affirming terminality. More information can be derived at this link:

As concepts both Brain stem death and Brain Death differs.
In case of India & UK, Brain Stem Death and Brain Death Are used to pronounce death, although the criteria for declaring a person brain dead differs from country to country.
Health is not merely the absence of disease. Health is multifactorial. If this is the case, if a formerly "dead" person arises. Who is to say if that entity is fully recovered, without any late effects, that such a phenomenon is nothing short of a mystery. It is a given, we as humans do not have the last card, when it comes to the inner workings of human functionality. Let none of us, regale ourselves as being heirs to the secrets of The Book In Which Our Parts Are Recorded.
Brain stem death is the same as brain death. In brain stem death the criteria for brain death will be there.
Diagnosis of brain death (BD) varies around the world. In some countries BD diagnosis relies on clinical evaluation alone, i.e. evaluation of brainstem reflexes (pupillary light reflex, oculo-cephalic, gag reflex, apnea test, etc.); in these cases brainstem death is brain death, and patients can donate their organ for transplantation. In other countries some ancillary tests are mandatory, for example flat EEG in Italy or absent cerebral circulation in Northen European countries. It is curious that some patients would be declared brain dead in some countries but not in others!
A current arguement exists in regard how appropriate to use the terminology of brain death, which is ideally an autopsy diagnosis. However, neurologists tend to test & talk about brainstem death/dysfunction, classically defined by the Academy of Medical Royal Colleges as The irreversible loss of the capacity for consciousness, combined with irreversible loss of the capacity to breathe. Of course many other medical, legal & social definitions are available worldwide.
In brain stem death there is loss of function of respiratory centre and vasomotor centre,patient cannot have respiration of his own and blood pressure has to be supported from outside.such a patient is pronounced brain dead as there is no intrinsic vital activity of these centres.I
Brain stem death is essentially a clinical diagnosis, whereas brain death requires formal signs / proof that telencephalic structures have irreversibly been damaged.
