A 65 year old male is brought to the outpatient clinic with a one year illness marked by forgetfulness, visual hallucinations, suspiciousness, personality decline, poor self care and progressive deterioration in his condition. His Mini Mental Status Examination (MMSE) score is 10. What is his most likely diagnosis?

Question

Image below highlights jugular foramen. Which of the following structures do not pass through the marked structure “A”?

Answer 1

This question gives an elderly man with a year-long, worsening illness that includes forgetfulness, visual hallucinations, suspicion of others, a change in personality, and loss of self-care skills, along with a very low MMSE score of 10. The task is to pick the diagnosis that best fits this pattern.

Dementia: A chronic, progressive loss of memory and thinking skills in an older adult, often with hallucinations and personality change added in. This matches the case closely, including the very low MMSE.
Schizophrenia: Typically begins in the teens or twenties, and its hallucinations are not paired with a year of steady memory decline and a crashing MMSE score in a 65 year old.
Mania: Presents with high energy, elevated or irritable mood, and less need for sleep, none of which are described here.
Depression: Can slow thinking and cause forgetfulness in older people, but visual hallucinations and a full year of progressive deterioration fit dementia far better than a mood disorder.

Putting the age, the one year progressive course, the low MMSE, and the mix of memory loss with hallucinations and personality change together, dementia is the best fit.

Let's summarize:

A slow, one year cognitive decline in an elderly patient with a low MMSE score signals dementia.
Visual hallucinations and personality change can occur within dementia, especially dementia with Lewy bodies.
Schizophrenia, mania, and depression do not explain this steady cognitive fall.

So the correct answer is dementia.
