Its causes are unknown, as is a cure for it. A progressive disease, the first symptom is mild forgetfulness, but it eventually results in death. An estimated over four million people in the United States have Alzheimer's disease, which generally sets in after age sixty. It is the most common form of... After the initial symptoms of memory loss comes difficulty performing every day thinking tasks such as simple math problems. This is due to the death of nerve cells in the brain's memory center. Some physiological signs of Alzheimer's are the formation of clumps in the brain and the tangling of nerve fibres, called, respectively... As Alzheimer's progresses, symptoms of memory loss and changes in mood and behavior begin dramatically affecting daily living. As the brain degenrates, people forget how to do simple things like brushing their teeth and forget the names of close family. Currently, doctors are unable to see the physiological changes in the brain Alzheimer's creates without conducting an autopsy after death. However, studies are being done to find out whether the clumps and tangles can be seen with an MRI. This section of the brain is responsible for managing basic emotions such as fear and anger. Alzheimer's severely damages the amygdala, causing emotional instability. Paranoia, temper outbursts and bouts of anxiety are common. In the early stages of Alzheimer's disease, damage to the brain stem results in erratic sleep patterns. As Alzheimer's progresses, sensory problems involving vision and hearing also occur. Continued damage to the brain stem creates other complications, such as difficulties swallowing, breathing and erratic blood pressure and arrhythmia. The hippocampus is primarily responsible for short-term memory. Alzheimer's begins attacking the hippocampus early in development. Diminished short-term memory capacity and slight disorientation results immediately. Could we be the generation to solve it?
