BANK MULTI-INFARCT DEMENTIA & VASCULAR
COGNITIVE IMPAIRMENT MASTER GUIDE
This comprehensive, high-yield exam bank contains
premium practice questions with detailed rationales covering
the pathophysiology, clinical features, diagnostic scoring,
and pharmacological management of Multi-Infarct Dementia.
Designed specifically to mimic advanced medical and
nursing board layouts, it provides students with clear
structural context to confidently master complex
cerebrovascular cognitive disorders. It serves as an
essential, high-converting digital asset for online academic
stores, helping educators and student sellers maximize their
download counts and study-guide revenue
1. A 74-year-old female is brought to the clinic by her family,
who notes that her cognitive abilities declined sharply over a
weekend three months ago, stabilized, and then dropped
significantly again last week following a transient ischemic
attack (TIA). This pattern is most indicative of which
pathology?
A) Alzheimer’s disease
B) Frontotemporal lobar degeneration
, C) Multi-Infarct Dementia (MID)
D) Dementia with Lewy bodies
Answer: C
Rationale: Multi-Infarct Dementia (MID) is characterized
by a classic stepwise decline, where periods of stable
cognitive function are punctuated by sudden, abrupt
drops in capability corresponding to distinct ischemic
events. Alzheimer's follows a gradual, linear decline,
while Lewy body dementia features prominent visual
hallucinations and motor parkinsonism.
2. When reviewing the medical history of a patient with
suspected Multi-Infarct Dementia, which of the following co-
morbidities carries the highest relative risk for driving small
vessel lipohyalinosis?
A) Chronic osteoarthritis
B) Long-standing, poorly controlled hypertension
C) Idiopathic pulmonary fibrosis
C) Hypothyroidism
Answer: B
Rationale: Hypertension is the primary driver of
lipohyalinosis and arteriolosclerosis in the small,
penetrating cerebral arteries. This narrowing leads to
lacunar infarcts and ischemic white matter changes that
cumulative cause Multi-Infarct Dementia.
3. A patient suspected of having Multi-Infarct Dementia scores
an 8 on the Hachinski Ischemic Score (HIS). How should the
clinician interpret this finding?
A) The score is inconclusive and requires a lumbar puncture.
B) The score strongly points toward a primary
, neurodegenerative disorder like Alzheimer's.
C) The score strongly supports a diagnosis of vascular
dementia/MID.
D) The score indicates a pure psychiatric manifestation, such
as major depressive pseudodementia.
Answer: C
Rationale: On the Hachinski Ischemic Score (HIS), a
score of 7 or higher is highly predictive of a vascular
etiology (Vascular Dementia/MID), whereas a score of 4
or lower points toward an Alzheimer's type pathology.
4. Neuroimaging reveals multiple small, punched-out fluid-filled
cavities (0.2 to 15 mm) located in the basal ganglia and
internal capsule of a patient displaying cognitive decline.
These lesions are pathologically classified as:
A) Neoplastic shifts
B) Lacunar infarcts
C) Oligodendrogliomas
D) Arteriovenous malformations
Answer: B
Rationale: Lacunar infarcts are small, chronic ischemic
cavities left behind after the occlusion of deep
penetrating arterioles supplying structures like the basal
ganglia, thalamus, and internal capsule. Accumulation
of these silent strokes is a hallmark cause of subcortical
MID.
5. Which cognitive domain is typically affected earliest and
most severely in patients with Multi-Infarct Dementia
compared to early-stage Alzheimer's disease?
A) Episodic memory retrieval
, B) Executive functioning and processing speed
C) Visual-spatial orientation
D) Semantic naming capacities
Answer: B
Rationale: Because MID frequently damages subcortical
white matter networks and frontal-striatal circuits,
executive dysfunction (planning, organizing, abstract
thinking) and slowed processing speed typically
precede or overshadow pure episodic memory loss,
which characterizes early Alzheimer’s disease.
6. A 69-year-old patient with multi-infarct dementia exhibits
sudden emotional outbursts, shifting rapidly from
unprovoked crying to laughter without corresponding internal
mood changes. This clinical feature is known as:
A) Anosognosia
B) Wernicke's aphasia
C) Pseudobulbar affect
D) Agonistic dyskinesia
Answer: C
Rationale: Pseudobulbar affect (emotional incontinence)
occurs due to bilateral lesions in the corticobulbar
pathways, disrupting the upper motor neuron control of
emotional expression. This is a common and distressing
focal sign in advanced MID.
7. Which of the following gait abnormalities is most
characteristically observed during physical examination in a
patient suffering from subcortical Multi-Infarct Dementia?
A) Steppage gait due to foot drop
B) Choreic, dancing gait
