Transcript of Alzheimer's Disease

Alzheimer's Disease
What happens to the cells during the process?
The healthy cells in the brain are damaged by the plaque and tangles in the nerves caused by Alzheimer's disease. The cellular debris also causes micro-tubules to collapse and prevents the cells from working properly. When the cells are being blocked they can't send messages to each other. Which makes it difficult for the brain to properly control the body. Due to all this cellular debris, neurons and other nerve cells start to die little by little.
How is Alzheimer's contracted?
The symptoms resulting in Alzheimer's disease first appear to people from 30 to 60 years of age. Scientists are not certain on exactly what causes Alzheimer's disease and why it only affects an older age group. Though, it is believed that this disease is created by a combination of genes and environmental factors. It only takes one parent with a defective copy of this gene to pass it down to their child in order for them to obtain this disease.
What are the affects of Alzheimer's disease?
In the first stages of Alzheimer's disease, the only symptoms include constant confusion and the mild difficulty to remember past events. But as the disease progresses, the amount of brain cell loss increases. This causes may other symptoms to appear. These symptoms include:

Loss of speaking, thinking and writing skills
Difficulty in making decisions
Difficulty in completing simple tasks
Changes in personality and behaviour
Growing confusion of spatial relationships

The symptom that most affects a patient with Alzheimer's disease is their loss of memory. To be more specific, their loss of recent memories. As time progresses, the patient will begin to forget the names and faces of their friends and family. This disease will not only affect the patient containing the disorder , but also their many loved ones.
Can Alzheimer's be treated and how?
Scientists have not found a cure for Alzheimer's disease, therefore the life of a patient with this disease will end in death. But several medications are available to these patients to slow down some of their symptoms. Due to the many symptoms caused by this disease, patients with Alzheimer's disease often need a "caregiver". A caregiver is a person who helps the patient with the things that they can no longer do because of the disease. Scientists are working hard to find a cure for Alzheimer's disease and someday that cure will be found!
Fun Facts
What life system does Alzheimer's disease affect?
Alzheimer's mainly affects the nervous system, more specifically the brain. The brain is targeted by Alzheimer's through the nerves. The brain of a person with Alzheimer's contains clumps of cellular debris and proteins (plaques). The brain also reduces the amount of neurotransmitters that allow nerve cells to communicate with each other.
What is Alzheimer's Disease?
Alzheimer's is a fatal disease that destroys brain cells. It is the most common form of dementia, or loss of brain function. Alzheimer's is an irreversible brain disease that slowly destroys how you think and feel. It also affects the memory and can even make someone forget their own identity. Did you know that Alzheimer's disease was named after Alois Alzheimer, a german doctor who named this disease in 1906?

That's the end of our presentation and we hope you enjoyed it!
This is how a brain with advanced Alzheimer's looks like. The cortex shrivels up, the hippocampus shrinks and the ventricles grow larger.
This is what a healthy brain without Alzheimer's looks like. It has no signs of shrinkage and no dying neurons.

Dementia : a disorder of the mental processes caused by brain disease or injury and marked by memory disorders, personality changes, and impaired reasoning.

Neurotranmitters: a chemical substance that transmits nerve inpulses across a synapse.

Micro-tubules: a microscopic tubular structure present in numbers in the cytoplasm of cells

Synapse: a junction between two nerve cells.

Cortex: the outer layer of the cerebrum or the brain.

Ventricle: is a set of structures containing cerebrospinal fluid in the brain. It is continuous with the central canal of the spinal cord.
