Q

Clanging

A

Speech with choice of words based on sound, rather than meaning, as in rhyming and punning. For example, “Look at my eyes and nose, wise eyes and rosy nose. Two to one, the ayes have it!”

31
Q

Confabulation

A

Fabrication of facts or events in response to questions, to fill in the gaps from impaired memory

32
Q

Derailment (loosening of associations)

A

Tangential speech with shifting topics that are loosely connected or unrelated. The patient is unaware of the lack of association.

33
Q

Echolalia

A

Repetition of the words and phrases of others

34
Q

Flight of ideas

A

An almost continuous flow of accelerated speech with abrupt changes from one topic to the next. Changes are based on understandable associations, plays on words, or distracting stimuli, but ideas are not well connected.

35
Q

Incoherence

A

Speech that is incomprehensible and illogical, with lack of meaningful connections, abrupt changes in topic, or disordered grammar or word use. Flight of ideas, when severe, may produce incoherence.

36
Q

Neologisms

A

Invented or distorted words, or words with new and highly idiosyncratic meanings.

37
Q

Perseveration

A

Persistent repetition of words or ideas

38
Q

Delirium

A

, a multifactorial syndrome, is an acute confusional state marked by sudden onset; fluctuating course; inattention; and, at times, changing levels of consciousness

39
Q

Parietal lobe

A

Involved in visuospatial sense, attention, and movement.1,64

Deficits in parietal lobe function have been associated with attention-deficit/hyperactivity disorder (ADHD), obsessive–compulsive disorder (OCD), and schizophrenia.

40
Q

Temporal lobe: primary auditory cortex

A

Responsible for auditory processing.

In schizophrenia, the primary auditory cortex activates even in the absence of sound, which often result in the experience of auditory hallucinations

41
Q

Temporal lobe: hippocampus

A

Critical to memory and learning.70–72 There is also high concentrations of cortisol receptors in the hippocampus.

Hippocampus dysfunction may contribute to cognitive impairment in Alzheimer disease (AD) and schizophrenia.73,74

Major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) both cause significant increases of cortisol, which may cause memory and cognitive problems seen in these disorders.75–78

Hippocampus dysfunction is also thought to contribute to anxiety symptoms

42
Q

Temporal lobe: amygdala

A

Involved in the cortical processes that cause emotions. The fight-or-flight response, or fear response, is activated through the amygdala.

In people with posttraumatic stress disorder (PTSD), the amygdala is often hyperactivated and cannot be easily turned off.78 People with PTSD often startle easily and struggle with anxiety or panic.

Excess amygdala activity is also seen in people with bipolar disorder, which is thought to contribute to irritability and labile mood

43
Q

Frontal lobe

A

Vital to executive function (which includes memory, cognition, behavioral control, and attention) and emotions.

Dysfunction has been associated with most mental disorders, including bipolar disorder, schizophrenia, attention-deficit/hyperactivity disorder, major depressive disorder (MDD), obsessive–compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and AD

44
Q

Basal ganglia

A

Works with the nucleus accumbens to control reward.

Dysfunction seen in addiction,77,106 obsessive–compulsive disorder (OCD), major depressive disorder (MDD), attention-deficit/hyperactivity disorder (ADHD), schizophrenia, and bipolar disorder.

45
Q

pineal gland

A

Produces melatonin, which regulates sleep.1

Contributes to sleep disturbances in major depressive disorder (MDD), obsessive–compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and AD

46
Q

Hypothalamus

A

Periods of increased stress are associated with increased activity of the hypothalamic–pituitary–adrenal axis and increased release of corticotropin-releasing factor, which causes cortisol (a steroid hormone) release.

Increased cortisol can cause depressive symptoms.

47
Q

Cerebellum

A

Regulates motor coordination and motor learning

Alcohol use impairs cerebellar function, which can cause ataxia, or a loss of motor coordination.1

48
Q

Somatic symptom disorder

A

Somatic symptoms are either very distressing or result in significant disruption of functioning, as well as excessive and disproportionate thoughts, feelings, and behaviors related to those symptoms. Symptoms should be specific if with predominant pain.

49
Q

Illness anxiety disorder

A

Preoccupation with having or acquiring a serious illness where somatic symptoms, if present, are only mild in intensity

50
Q

Conversion disorder

A

Syndrome of symptoms of deficits mimicking neurologic or medical illness in which psychological factors are judged to be of etiologic importance

51
Q

Factitious disorder

A

Falsification of physical or psychological signs or symptoms, or induction of injury or disease, associated with identified deception. The individual presents himself or herself as ill, impaired, or injured even in the absence of external rewards.

52
Q

Body dysmorphic disorder

A

Preoccupation with one or more perceived defects or flaws in physical appearance that are not observable or appear only slight to others.

53
Q

Dissociative disorder

A

Disruption of and/or discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior.

54
Q

The most important geriatric syndromes in primary care are

A

falls, urinary incontinence, frailty, and cognitive impairment.

55
Q

Primary aging reflects

A

changes in physiologic reserves over time that are independent of changes from disease.

56
Q

BP in older adults

A

Tends to rise with aging, d/t large arteries stiffening and becoming atherosclerotic

57
Q

actinic purpura

A

, that fade over time. These spots and patches come from blood that has leaked through poorly supported capillaries and spread within the dermis

58
Q

presbycusis

A

Hearing loss associated with aging, known as ,

59
Q

a fourth heart sound

A

As a person ages, decreased ventricular compliance and impaired ventricular filling result in this, often auscultated in otherwise healthy older people

60
Q

auscultating a third heart sound,

A

is strongly suggestive of heart failure from volume overload of the left ventricle in conditions like heart failure and valvular heart disease

61
Q

Calcium resorption from bone, rather than diet, increases with aging as

A

parathyroid hormone levels rise

62
Q

Sarcopenia

A

is the loss of lean body mass and strength with aging

63
Q

geriatric syndrome

A

is “a multifactorial condition that involves the interaction between identifiable situation-specific stressors and underlying age-related risk factors, resulting in damage across multiple organ systems

64
Q

activities of daily living (ADLs),

A

which consist of six basic self-care abilities—bathing, dressing, toileting, transferring, continence, and feeding.

65
Q

the instrumental activities of daily living (IADLs)

A

—using the telephone, shopping, preparing food, housekeeping, laundry, transportation, taking medicine, and managing money.

66
Q

the single most common modifiable risk factor associated with falls

A

Medications

67
Q

Older adults should have no more than

A

2 drinks on any one day or 7 drinks a week.

68
Q

A

encompasses the alleviation of pain and suffering and the promotion of optimal quality of life across all phases of treatment, including curative interventions and rehabilitation

69
Q

orthostatic or postural hypotension

A

, defined as a drop in SBP of ≥20 mm Hg or DBP of ≥10 mm Hg within 3 minutes of standing

70
Q

entropion

A

the eyelashes in the lower lids to see whether they are directed toward the eye

71
Q

ectropion

A

sagging and outward turning of the lower eyelid and eyelashes

72
Q

Get Up and Go Test

A

Performed with patient wearing regular footwear, using usual assistive device if needed, and sitting back in an armless chair. After instructing the patient on what to do, on the word “Go,” the patient should:

Get up from the armless chair
Walk 3 m (in a line)
Turn around
Walk back to the chair
Sit back down
Time the second effort. Observe patient for postural stability, steppage, stride length, and sway.

Scoring:

Normal: completes task in <10 seconds
Abnormal: completes task in >20 seconds
