TOPIC 1: ALZHEIMER'S DISEASE
10 Questions • 9.9% of Exam • Focuses on the genetics, neuroimaging, and clinical features of Alzheimer's disease.
QUESTION 1
Genetics AD
Answer: Genes play a strong role- heritability of 58-79% for late onset and over 90% for early onset.
Rationale: The provided answer correctly identifies the significant genetic influence on Alzheimer's disease
(AD). It highlights that heritability estimates for late-onset AD range from 58% to 79%, and for earlyonset AD, it exceeds
90%, indicating a strong genetic predisposition.
QUESTION 2
Neural networks AD
Answer: Damage to synapses, mitochondrial abnormalities, and inflammatory processes cause NTM failure
and neuronal death.
Rationale: Neurotransmitter (NTM) failure in Alzheimer's disease (AD) stems from damage to synapses, which are critical
for neuronal communication. Additionally, mitochondrial abnormalities impair energy production within neurons, and
inflammatory processes contribute to neuronal degeneration.
QUESTION 3
Does AD lead to an increase or decrease in this NTM activity
Answer: Leads to a decrease in NTM activity.
Rationale: Leads to a decrease in NTM activity, a hallmark of Alzheimer's disease (AD), are known to disrupt synaptic
function. This disruption is mediated, in part, by Aβ's interaction with neuronal receptors and signaling pathways.

QUESTION 4
What are the hallmark signs on neuroimaging studies that distinguish AD from other
disorders?
Answer: Amyloid plaques and neurofibrillary tangles.
Rationale: Amyloid plaques and neurofibrillary tangles are the defining neuropathological hallmarks of Alzheimer's disease
(AD). While neuroimaging cannot directly visualize these microscopic structures, their presence leads to characteristic
macroscopic changes that can be detected.
QUESTION 5
WHAT ARE THE TWO HALLMARKS OF AD?
Answer: Amyloid plaques and neurofibrillary tangles -•Responsible for issues with memory and higherlevel
thinking.
Rationale: Alzheimer's disease (AD) is pathologically defined by the presence of extracellular amyloid plaques and
intracellular neurofibrillary tangles. These protein aggregates disrupt normal neuronal function and synaptic transmission,
leading to the cognitive deficits characteristic of AD, such as memory impairment and difficulties with higher-level cognitive
processes.
QUESTION 6
Major Neurocognitive disorder d/t a specific medical etiology:
Answer: •Parkinson's disease, traumatic brain injury, HIV infection, Huntington's disease, prion disease (e.g.,
Creutzfeldt-Jakob disease), frontotemporal lobar degeneration (e.g., Pick's disease), Lewy body disease,
vascular disease, and Alzheimer's disease.
Rationale: Major neurocognitive disorders can be caused by specific underlying medical conditions. The provided answer
lists several such conditions, including neurodegenerative diseases like Parkinson's, Huntington's, and Alzheimer's, as well
as acquired conditions such as traumatic brain injury, HIV infection, and vascular disease.
