Which of the following is a common EARLY symptom of dementia?
Difficulty finding the right words
Losing sense of direction in familiar places
What is believed to be a leading cause of dementia?
Frequent physical exercise
abnormal build-up of proteins
Which part of the brain is first affected by Alzheimer's Disease, a common type of dementia?
Which of the following is not a typical form of non-Alzheimer’s dementia?
Hypertensive dementia is not a typical form of non-Alzheimer’s dementia. Vascular dementia, frontotemporal dementia, and Lewy body dementia are established types.
Which of these is a known risk factor for developing dementia?
High blood pressure can cause vascular damage and lead to brain atrophy as well as an increased risk of a stroke
What role does genetics play in dementia?
A significant role, especially in early-onset forms
True or False? High blood sugar is linked to an increased risk of developing dementia
When blood sugar levels are consistently high, it can lead to damage in the blood vessels throughout the body, including those in the brain. This vascular damage can reduce blood flow to the brain, leading to vascular dementia. Additionally, high blood sugar can contribute to inflammation and other biochemical changes in the brain that may exacerbate the development of Alzheimer's disease and other types of dementia. Managing blood
What is the term for when dementia symptoms worsen in the evening?
How is dementia diagnosed?
Through a single blood test
By identifying symptoms and ruling out other conditions
What percentage of dementia cases worldwide does Alzheimer’s disease account for?
Which imaging technique is most commonly used to observe brain changes in patients with suspected dementia?
Positron Emission Tomography (PET) is most commonly used to observe brain changes in patients with suspected dementia. PET scans can detect amyloid plaques and other changes related to dementia.
Positron Emission Tomography (PET)
Electroencephalogram (EEG)
Recent studies suggest that the risk of dementia can be reduced by managing hearing loss. What is the proposed mechanism for this relationship?
Recent studies suggest that managing hearing loss may reduce the risk of dementia because better hearing increases social interactions, which enhance cognitive reserve and overall brain health.
Improved hearing reduces brain strain and cognitive load
Hearing aids emit frequencies that stimulate brain activity
Better hearing increases social interactions, which enhance cognitive reserve
Managing hearing loss improves balance and prevents head injuries
ApoE4 is a gene variant known to influence the risk of developing Alzheimer's disease. How does having one ApoE4 allele compare to having two in terms of risk level?
Having one allele does not affect the risk
Having two alleles slightly increases the risk
Having one allele doubles the risk, while having two can multiply the risk by four
Having two alleles halves the risk compared to one
