Neurons start dying in this area first. It then spreads into the adjacent entorhinal cortex EC which acts as a central hub, for a widespread network that handles signals for memory and movement [9] like a main train station with train tracks going to different areas. The EC is the main area for communication between the hippocampus, and the neocortex - which is the outer portion of the brain responsible for higher functioning such as how the brain perceives information from the five senses; smell, sight, taste, touch and hearing; Ex. The disease then spreads into the hippocampus which is part of the limbic system.

The hippocampus is the part of the brain that is involved in forming new memories, organizing them, and storing them for later recall. It is also where emotions and senses, such as smell and sound are attached to specific memories. Example 1. Example 2.

The hippocampus then sends memories to the different parts of the cerebral hemisphere where they are placed in long-term storage and it helps retrieve them when necessary. Example: An adult trying to remember the name of a classmate from kindergarten.

In addition to handling memory the hippocampus is also involved in emotional responses, navigation getting around and spatial orientation knowing your sense of place as you move around Example: Knowing your way around your bedroom even with the lights off. There are actually two parts of the hippocampus which is shaped like a horseshoe with one in the left part of the brain and the other in the right part of the brain.

This is a short example of the test. The test is used to measure different cognitive functions such as selective attention. Naming the colors of the first set of words is easier and quicker than the second, because in the first set, the colors match the words, in the second set they do not.

So a person has to pay more attention. These small preclinical changes no symptoms in the brain may occur many years, to even a few decades before a person is diagnosed with Alzheimer's. With a stage where there is some memory loss, or mild cognitive impairment. These changes put a person at risk of developing the clinical symptoms of full-blown Alzheimer's but not everyone who has these changes will get the disease. Even though there is no cure for Alzheimer's, there are new treatments which are being developed which would work better in the very first stages of the disease.

At this time exactly what makes up the preclinical phase of Alzheimer's is still being researched, such as why some people with go on to develop Alzheimer's and others do not. So the term preclinical phase is being used for research only. In people with mild memory complaints, our accuracy is barely better than chance," according to study researcher P.

Murali Doraiswamy, MBBS, professor of psychiatry and medicine at Duke Medicine, "Given that the definitive gold standard for diagnosing Alzheimer's is autopsy, we need a better way to look into the brain. She was married and had a normal life until eight months prior to her commitment, when she started having psychological and neurological problems, such as problems with memory and language, paranoia, becoming disorientated and having hallucinations.

She was studied by a doctor on staff named Alois Alzheimer — Alzheimer became interested in her case because of her age; while the effects of senile dementia were known at the time, they usually did not start until a person was in their early to mid-sixties. Her case was also notable because of the rapid onset of dementia, only eight months, from the first reported symptoms, until she was committed.

While conducting one of his examinations of Ms. Deter, he asked her to perform a series of simple writing tasks. Unable to do what was asked such as write her name, she said "I have lost myself, so to speak" " Ich habe mich sozusagen selbst verloren ". Alzheimer left the hospital in Franfkurt in to begin working with Emil Kraepelin at the Psychiatric University Hospital in Heidelberg-Bergheim , and in both he and Kraepelin began working at Ludwig Maximilian University in Munich.

When Ms. Deter died of septicemia on 8 April , Alzheimer was informed and her brain was sent to Munich for him to study.

Studying samples of her brain under a microscope he noticed neurofibriallry tangles and bundles made up of beta-amyloid plaque, which are two of the main features of the disease. In , Emil Kraepelin named the disease 'Alzheimer's disease'. Alzheimer's disease usually beigins affecting people between ages 60—65, in Ms. Deter's case - who was years-old when she died - she had a form of what is now known as Early-onset Alzhiemer's disease. Anyone can get Alzheimer's disease, rich people or poor famous people and unfamous people.

Some of the famous people who have gotten Alzheimer's disease are former United States President Ronald Reagan and Irish writer Iris Murdoch , both of whom were the subjects of scientific articles examining how their cognitive capacities got worse with the disease.

The vesicles , which contain neurotransmitters , are brought to the end of the microtubule inside the neuron's brain cell axon to the synapse , to send a signal to the dendrite of the next neuron. Tangles The tau proteins holding the microtubules together undergo a chemical change called hyperphosphorylation. They now no longer hold the microtubule together. The two strands 'walking' down the microtubule is a motor protein called kinesin.

The kinesin is carrying a vesicle on top, with the neurotransmitters inside. It cannot finish its job because the microtubule has fallen apart. The pieces of hyperphosphorylated tau form tangles inside the neuron. The neuron eventually dies and the tangle is all that remains. The arterial wall has three layers. In cerebral amyloid angiopathy , beta-amyloid accumulates in the middle layer, the tunica media , and the outer layer, the tunica externa.

MRI scan showing Cerebral amyloid angiopathy. The beta-amyloid deposits show up as black 'dots' spread throughout the brain's outer layer, the cerebral cortex. This was how Auguste Deter, described what was happening to her. Steven G. Home Contact us Help Free delivery worldwide.
