Brain death

Drugs are chemicals that affect the brain by tapping into its communication system and interfering with the way neurons normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. Drugs that enter the blood stream have faster and definitely more intense effects. The more directly the drug enters the bloodstream determines how fast and intense the drug will take effect.…

who had gone into cardiac arrest in an out-of-hospital scenario to prevent neurological damage and the. The researchers hoped that if by inducing hypothermia early on after the cardiac arrest and loss of consciousness there would be little to no brain damage. The researchers believed that in order to get a better understanding of cooling temperatures the patients were to be randomly assigned a cooling temperature either at 33 ° C or at 36 °C group. From there a set of test would be preformed to…

Alzheimer’s is a permanent brain disorder that slowly destroys memory and thinking skills. It will eventually inhibit the ability to carry out the simplest daily tasks. More than 5 million people have the disorder. Adults younger than the age of 65 account for almost 500,000 cases. There are seven stages to Alzheimer’s. These seven stages range from no impairment to severe dementia. Dementia is the loss of cognitive functioning that interferes with a person’s daily life. Alzheimer’s disease is…

research the nervous system. The nervous system includes the brain, the spinal cord, and the peripheral nerves. It is a complex collection of nerves and neurons which carry messages to different parts of the body. The nervous system is responsible for responses of the body to environmental changes. The Nervous system is made up of two components: the central nervous system and the peripheral nervous system. The central nervous system entails the brain and the spinal cord. The peripheral nervous…

In 1997 Adrian Raine conducted a study that focused on brain abnormalities in murderers that were shown by the use of positron emission tomography (PET). “The aim of his experiment was to see if murderers who pleaded not guilty by the reason of insanity (NGRI) showed signs of brain abnormalities with PET scans. Raine used 41 participants, 39 of which were male and 2 of which were females. The prisoner’s reasons for insanity varied. Six said they were schizophrenic, 23 said it was due to a head…

Medicine were able to determine that a group of cells found in the adult brain remain highly active by transforming into insulating nerve fibers. These nerve fibers then formed scars that contributed to tissue repair when they were artificially inserted into a group of mice. Their work brings to light how these multifunctional cells communicate with one another in the central nervous system (CNS), also known as the brain and spinal cord. The removal of one of these special cells, known as…

the Peace, Eric Williams, convicted and sentenced to death for the murders of: District Attorney Mike McLelland, his wife Cynthia, and top prosecutor Mark Hasse.

why does it cause forgetfulness? Alzheimer’s is a disease, which causes memory loss, and it causes difficulty dealing with daily life (1). Alzheimer’s disease happens because damage of cells in certain regions of the brain and these areas relate memory (2). Over time, all brain cells will die. As a result, it will cause for Alzheimer’s patient difficulty dealing with daily life (2). It has three stages which are mild Alzheimer's disease (early-stage) ، moderate Alzheimer's disease…

Human Brains Causes of Subarachnoid Hemorrhage Chanda Bajracharya February 9, 2018 Midwestern State University Abstract The anatomical study of the brain is known as neuroanatomy, whereas the study of their function is known as neuroscience. The human brain is an extraordinarily powerful organ of the body. It helps to function all the body parts and the amazing fact is it weights around three pounds only. It is covered by the skulls. The largest part of the human brain is cerebrum.…

between life and death. Advancement’s in technology are making an early diagnosis for many diseases possible. One of these diseases is Alzheimer’s disease. According to the Alzheimer’s Foundation of America, (AFA, 2015) “Worldwide it is estimated that 24 million people have dementia, the majority of these people are also thought to have Alzheimer’s disease.” The AFA (2015) also states that, “Alzheimer’s Disease affects 5.1 million Americans, making it a top ten leading cause of death in the…
