Which of the following pathophysiological processes would a clinician most likely expect in a client with a diagnosis of dementia rather than delirium?
A)
Involvement of cholinergic neurons has caused an accumulation of acetylcholine within synapses.
B)
Hypothyroidism has contributed to a decrease in metabolic activity manifesting in neural inefficiency.
C)
Dehydration secondary to diuretic overuse has manifested in changes in perception.
D)
Plaques have developed between neurons, and neurofibrillary tangles have developed within neurons.
Ans:
D
Feedback:
In Alzheimer disease, there are senile plaques that develop between neurons and neurofibrillary tangles that develop within neurons. There is a decline in synaptic levels of acetylcholine rather than accumulation. Dehydration and hypothyroidism would be associated with delirium, not dementia.
