Amyloid

Prion infectious diseases: History and molecular pathology It is circa 500 BC, and Hippocrates records rare but localised outbreaks of madness within livestock; he observes that the animals’ neurological capabilities rapidly decline after years of apparent normality. When he investigates, he finds that the brains of these animals are ‘very full of dropsy and of an evil odour’. He hypothesises that this disease would be able to spread and infect humans too (McAlister, 2005). To him, this is…

Legalization Of Marijuana The United States Of America’s Declaration of Independence says, we are subject to "Life, Liberty, and the pursuit of Happiness." These unalienable rights are taken away under the illegalization of marijuana. As other substances like alcohol are legal, marijuana should be too. The wishes of our Founding Fathers should not be broken unless our liberty and happiness lead to adverse consequences and the use of marijuana does not. I strongly believe in the legalization of…

have this gene you are for sure getting Alzheimer’s. Many doctors who have patients see two different types of abnormalities when viewing a person’s brain with Alzheimer’s. The first thing that doctors will notice is clumps of proteins, or beta-amyloid, that damage and destroy brain cells. These plaques are interfering with cell-to-cell communication. The other thing that doctors notice on a patient is that their brain cells are depending on internal…

“Memory is a way of holding on to the things you love, the things you are, and the things you never want to lose” –Kevin Arnold. We all have memories, good and bad, that we cherish. Imagine all of those memories slowly being taken away from you, one by one. Not only have you lost memories, but also you have lost your independence, your relationships, and the ability to care for yourself. These are all things that happen to a person with Alzheimer’s disease (AD). AD is a progressive,…

Glucotoxicity due to chronic hyperglycaemia. The abnormal incretin effect resulting in reduced levels of GIP and GLP-1, which promote insulin release. Amyloid deposits within the islets of beta cells, which may be either a cause or effect of long-standing type 2 diabetes. Many of the genetic polymorphisms which are associated with a lifetime increase in type 2 diabetes risk occur in genes regulating insulin…

age (Younger). The disease is named after a doctor, Alois Alzheimer, where in 1906, he found changes in a woman’s brain tissue after she had died of a mental illness. During her examination he noticed there were abnormal clumps, now know today as amyloid plaques as well as jumbled bundles of fibers (About Alz…). It is beyond incredible that someone can look inside a human’s already complex brain, pick out the abnormalities, and pin point that this is the cause of their mental illness. The…

Alzheimer, who, in 1906, noticed changes in the brain tissue of a woman who experienced memory loss, language deficits, and unpredictable behavior. After the woman’s death, Dr. Alzheimer examined her atrophied brain and discovered abnormal clumps (amyloid plaques) and tangled fibers (neurofibrillary, or tau, tangles) (“Fact”).…

Vascular dementia is defined by Zhong et al. (2016) as a general dementia caused by a series of cerebral vascular factors such as ischemic cerebral vascular disease. The dementia is very similar to Alzheimer’s disease and they share some symptoms such as impaired memory and cognitive function. Some of the non-cognitive symptoms of vascular dementia include tinnitus, sleeping disorder, numbness of the extremities, and emotion changes. Calabrese et al. (2016) believes there are two principal…

The Impact of Sleep Deprivation “If you 're an average sort of person, 36% of your life will be spent asleep, which means that if you live to ninety, then thirty two years will have been spent entirely asleep.” Russell Foster - a neuroscientist – said in his presentation about “Why Do We Sleep?” on Ted Talks (Foster). The numbers that Foster provided can clearly show how important sleep is; however, a lot of people do not spend enough time sleeping. Statistics by CDC (the Center for Disease…
