Understanding Alzheimer’s Disease as a Type of Cortical Dementia
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Understand the basics of Alzheimer’s disease | Alzheimer’s disease is a type of cortical dementia that affects brain cell damage, memory loss, language impairment, spatial awareness decline, personality changes, and cognitive decline. | Age, genetics, family history, head injuries, and lifestyle factors such as smoking and lack of exercise. |
| 2 | Learn about the progressive nature of Alzheimer’s disease | Alzheimer’s disease is a progressive disorder that worsens over time, leading to severe cognitive decline and eventually death. | Age is the biggest risk factor, with the likelihood of developing Alzheimer’s disease doubling every five years after the age of 65. |
| 3 | Understand the neurodegenerative condition of Alzheimer’s disease | Alzheimer’s disease is a neurodegenerative condition that causes plaques and tangles to form in the brain, leading to beta-amyloid protein buildup and nerve cell death. | Other risk factors include having Down syndrome, having a history of depression, and having high blood pressure or high cholesterol. |
| 4 | Compare Alzheimer’s disease to other types of dementia | Alzheimer’s disease is just one type of dementia, with other types including dementia with Lewy bodies and vascular dementia. | It is important to understand the specific type of dementia a person has in order to provide appropriate care and treatment. |

Huntington’s Disease: A Unique Form of Subcortical Dementia
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Understand the basics of Huntington’s Disease | Huntington’s Disease is a neurodegenerative disease that affects the basal ganglia, a part of the brain responsible for movement and coordination. It is caused by a gene mutation that leads to the production of abnormal proteins, which damage brain cells over time. | The risk of developing Huntington’s Disease is inherited, with a child of a parent with the disease having a 50% chance of inheriting the gene mutation. |
| 2 | Recognize the motor symptoms of Huntington’s Disease | The most recognizable symptom of Huntington’s Disease is chorea, which is characterized by involuntary movements of the limbs, face, and torso. Other motor symptoms include rigidity, bradykinesia, and dystonia. | Motor symptoms of Huntington’s Disease can be managed with medication, but there is no cure for the disease. |
| 3 | Understand the cognitive decline associated with Huntington’s Disease | In addition to motor symptoms, Huntington’s Disease also causes cognitive decline, including difficulties with memory, attention, and executive function. | Cognitive decline in Huntington’s Disease is caused by damage to the subcortical regions of the brain, which are responsible for processing and relaying information to the cortex. |
| 4 | Recognize the psychiatric symptoms of Huntington’s Disease | Huntington’s Disease can also cause psychiatric symptoms, including depression, anxiety, irritability, and apathy. These symptoms can be just as debilitating as the motor and cognitive symptoms of the disease. | Psychiatric symptoms of Huntington’s Disease can be managed with medication and therapy. |
| 5 | Understand the genetic basis of Huntington’s Disease | Huntington’s Disease is caused by a mutation in the HTT gene, which leads to the production of abnormal proteins that damage brain cells. The mutation is characterized by the presence of CAG repeats, which are a sequence of three nucleotides that are repeated multiple times in the gene. | The number of CAG repeats in the HTT gene is directly correlated with the age of onset and severity of symptoms in Huntington’s Disease. |
| 6 | Recognize the different forms of Huntington’s Disease | There are two forms of Huntington’s Disease: adult onset and juvenile onset. Adult onset typically begins in middle age and progresses slowly, while juvenile onset begins in childhood or adolescence and progresses rapidly. | Juvenile onset Huntington’s Disease is less common than adult onset, but it is often more severe and has a faster progression. |
| 7 | Understand the role of neurotransmitter imbalance in Huntington’s Disease | Huntington’s Disease is characterized by a deficiency of the neurotransmitter dopamine, which is responsible for regulating movement and mood. This deficiency is caused by damage to the basal ganglia, which are responsible for producing and regulating dopamine. | Treatment options for Huntington’s Disease often involve medications that increase dopamine levels in the brain. |
| 8 | Recognize the limitations of current treatment options | While there are medications that can help manage the symptoms of Huntington’s Disease, there is currently no cure for the disease. Additionally, some medications can have side effects that are difficult to manage. | Research is ongoing to develop new treatments for Huntington’s Disease, including gene therapy and stem cell therapy. |
Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Cortical dementia and subcortical dementia are the same thing. | Cortical dementia and subcortical dementia are two different types of dementia that affect different parts of the brain. Cortical dementia affects the outer layer (cortex) of the brain, while subcortical dementia affects structures beneath the cortex. |
| Only elderly people can develop cortical or subcortical dementia. | While it is more common for older adults to develop these types of dementias, they can also occur in younger individuals due to factors such as genetics or traumatic brain injury. |
| Memory loss is always a symptom of both cortical and subcortical dementias. | While memory loss is a common symptom in many types of dementias, it may not be present in all cases of cortical or subcortical dementias. Other symptoms may include changes in mood, behavior, language abilities, movement coordination, and executive function skills like decision-making and problem-solving. |
| There are no effective treatments for either type of dementia. | While there is currently no cure for either type of dementia, there are medications that can help manage symptoms and improve quality-of-life for those affected by these conditions. Additionally, lifestyle modifications such as regular exercise and healthy eating habits have been shown to slow down cognitive decline associated with these diseases. |
