Neurocognitive Disorders Test A

The essential feature of the DSM-5 diagnosis of delirium is a disturbance in attention/awareness and in cognition that develops over a short period of time, represents a change from baseline, and tends to fluctuate in severity during the
course of a day. Which of the following additional conditions must apply?

A 79-year-old woman with a history of depression is being evaluated at a nursing home for a suspected urinary tract infection. She is easily distracted, perseverates on answers to questions, asks the same question repeatedly, is unable
to focus, and cannot answer questions regarding orientation. The mental status changes evolved over a single day. Her family reports that they thought she “wasn’t herself” when they saw her the previous evening, but the nursing report
this morning indicates that the patient was cordial and appropriate. What is the most likely diagnosis?

Which of the following is not a diagnostic criterion, feature, or marker of major or mild neurocognitive disorder with Lewy bodies (NCDLB)?

The diagnostic criteria for neurocognitive disorder (NCD) due to HIV infection include fulfillment of criteria for major or mild NCD and documented infection with human immunodeficiency virus (as confirmed by established laboratory
methods). Which of the following is a prominent feature of NCD due to HIV infection?

Which of the following features characterizes alcohol-induced major or mild neurocognitive disorder, amnestic-confabulatory type?

Depression, irritability, anxiety, obsessive-compulsive symptoms, and apathy are frequently associated with Huntington’s disease and often precede the onset of motor symptoms. Psychosis more rarely precedes the onset of motor symptoms. Which of the following is a core feature of major or mild neurocognitive disorder due to Huntington’s disease?

Major or mild neurocognitive disorder (NCD) due to prion disease encompasses NCDs associated with a group of subacute spongiform encephalopathies caused by transmissible agents known as prions. What is the most common prion disease?

Major and mild neurocognitive disorders (NCDs) exist on a spectrum of cognitive and functional impairment. Which of the following constitutes an important threshold differentiating the two diagnoses?

A 68-year-old semiretired cardiologist with responsibility for electrocardiogram (ECG) interpretation at his community hospital is referred by the hospital’s Employee Assistance Program for clinical evaluation because of concerns
expressed by other clinicians that he has been making many mistakes in his ECG interpretations over the past few months. The patient discloses symptoms of persistent sadness since the death of his wife 6 months prior to the evaluation, with frequent thoughts of death, trouble sleeping, and escalating usage of sedative-hypnotics and alcohol. He has some trouble concentrating, but he has been able to maintain his household, pay his bills, shop, and prepare meals by
himself without difficulty. He scores 28/30 on the Mini-Mental State Examination (MMSE). Which of the following would be the primary consideration in the differential diagnosis?

In a patient with mild neurocognitive disorder (NCD), which of the following would distinguish probable from possible Alzheimer’s disease?

The only way that mild NCD due to probable Alzheimer’s disease can be diagnosed is if there is evidence of a causative Alzheimer’s disease genetic mutation from either genetic testing or family history. Mild NCD due to possible Alzheimer’s disease is diagnosed on the basis of the presence of all of the clinical criteria described in options B–D above. Age at onset is not a diagnostic criterion.

A previously healthy 67-year-old man, who is experiencing an acute change in mental status, is brought to the emergency department by his family. There is no evidence in the initial history, physical examination, and laboratory studies to indicate substance intoxication or withdrawal, or to suggest another medical problem as the cause of his altered mental state. Over the course of 1 hour of observation, his level of alertness varies from alert but distractible, with apparent
auditory and visual hallucinations, to somnolent; he has difficulty sustaining attention to an examiner, and he cannot perform simple tasks such as serial subtractions or spelling words backwards. What is the most appropriate diagnosis?

Which of the following symptoms is not likely to be observed in a patient suffering from Alzheimer's disease?

The initial symptoms of a specific type of dementias (to which Pick's disease belongs) include language impairment and personality changes, rather than memory problems. Which type of dementia is described here?

Which of the following is NOT likely to be observed in patients suffering from Huntington's disease?
