Symptoms of This Disease
- Difficulty performing familiar tasks: Short-term memory loss is usually the first symptom of Alzheimer's disease. This includes forgetting how to do everyday tasks such as getting money out of an ATM or filling out a check.
- Problems with language: This is also a common sign of Alzheimer's disease. This symptom includes forgetting everyday words or common terms used on a daily basis. It is common for people to forget names or other words every once in a while, but this symptom involves people forgetting extremely common words and phrases.
- Extremely poor judgement: This symptom does not involve people making bad decisions every once in a while, rather it involves people not dressing appropriately or trusting a complete stranger.
- Disorientation: This symptom involves people forgetting or not knowing where they are or what time it is. This also includes extreme confusion, suspicion, fear or dependency
- Severe mood swings: This includes random emotional outbursts and severe changes in behavior.
Brain Size Comparison
As seen in the image above, Alzheimer’s disease literally causes the brain to decrease in size and capacity.
Brain Scan Comparison
The above image shows how a brain with Alzheimer’s disease consists of plaque that surrounds and smothers the brain tissue and causes dementia as a result of the disease. The healthy brain does not have much plaque at all.
Normal vs. Advanced Alzheimer's
The images on the left display a healthy brain while the images on the right display a brain affected by advanced Alzheimer's. The brain on the right is visibly much smaller and consists of many gaps and holes while the healthy brain is much larger and more full.

Who does Alzheimer's affect?
Methods of Treatment
Connection to the Biological Levels of Analysis
- This principle involves the effect of brain localization. Alzheimer's disease is caused by the brain shrinking and being smothered by plaque proteins. Parts of the brain are shut down and disabled by the plaque proteins. This causes the functions of those parts of the brain to become altered and in most cases stopped altogether.
2. Patterns of behavior can be inherited
- Alzheimer's is a disease that can be passed down from generation to generation. If Alzheimer's is common in someones family it is very likely that they will inherit the disease at some point in their life.
3. Animal research may inform our understanding of behavior
- According to Understanding Animal Research mice can be used to mimic Alzheimer's disease and develop possible treatments for the disease. Whenever mice are altered to mimic Alzheimer's disease they seemed to burrow and dig less than unaffected mice. This mimics the symptoms of people with Alzheimer's because they often forget how to do everyday tasks and processes.
Connection to the Cognitive Levels of Analysis
- People with Alzheimer's disease lose the ability to perform common tasks and display normal behavior. This is because their brain is unable to function properly and the mental processes are basically stopped. This shows how mental processes guide behavior because when the brain is altered, so are peoples actions and behavioral characteristics.
2. The mind can be studied scientifically
- Researchers can use brain scans to study and compare the brains of normal people to people with Alzheimer's disease. This helps them develop possible treatment methods and medicines that could eventually produce a cure for Alzheimer's disease.
3. Cognitive processes are influenced by social and cultural factors
- Memory is considered a cognitive process and people with Alzheimer's have an extremely limited capacity for memory. This influences their ability to socialize and communicate with others because they are unable to remember common words, tasks, processes and names of people they used to know.
