Table 1. Areas to Consider in a Sleep Assessment Interview
Nature of the complaint: what the problem is and when it occurs (e.g., sleep onset, sleep maintenance, early-morning wake up, daytime fatigue, nightmares)
Current sleep-wake schedule
History of sleep complaint (transient disturbance vs. long-standing complaint)
Symptoms of sleep disorders that may not be initially volunteered (e.g., restless legs, periodic limb movements, narcolepsy, gastroesophageal reflux, parasomnias, disruption of sleep-wake schedule)
Symptoms of sleep-disordered breathing (disturbed breathing at night, complaints of snoring, headache on waking, partner sleeps in another room)
Daytime states, routines, activities (sleepiness, fatigue, functioning, mood, activities, satisfaction with daily routines)
Naps, frequency, time of day, length
Sleep hygiene (daytime activity, exercise, sleep environment, activity in bed, diet, use of stimulants/depressants)
History of professional treatment of the sleep complaint and a review of what the client has tried to remedy the sleep problem
Medical/physical problems
Use of prescription and nonprescription drugs
Psychiatric history and mental status review (symptoms of depression, anxiety, thought disorder, other psychological maladjustment)
Stressful circumstances (currently and when sleep problems began)
Information regarding antecedents, consequences, secondary gains, precipitating factors, perpetuating factors

Table 2. Primary Aging: Changes in Anatomy and Function of Major Organ Systems
SystemAnatomical Changes With AgeFunctional Changes With Age
Cardiovascular
    HeartDecreased size, flexibility of collagen matrix; lipofuscin and fat deposition in myocardium; fatty infiltration and calcification of aortic and mitral valvesImpaired left ventricular diastolic filling, reduced β-adrenergic (i.e., chronotropic and inotropic) response to catecholamines, leading to decreased peak exercise cardiac index and ejection fraction
    ArteriesRedistribution and molecular rearrangement (cross-linking) of elastin and collagen in arterial walls; calcificationIncreased systolic blood pressure
Respiratory
    LungsEnlarged alveolar ducts and alveoli; loss of elasticityReduced ventilatory capacity, especially during exercise
    MusculoskeletalIncreased chest wall and joint rigidity; increased kyphosis; degeneration and calcification of cartilageSame as above
GastrointestinalSome loss of smooth muscle cells of intestine; atrophy of gastric mucosa; increase in gastric pH; some loss of hepatocytes; reduction in hepatic blood flowReduced eliminatory efficiency: constipation; reduced metabolism of drugs
GenitourinaryLoss of renal mass, loss of glomeruli, thickening of basement membrane of glomeruli and tubules, development of tubular diverticula, intimal thickening of arteries, development of afferent-efferent shunts in juxtamedullary glomeruli and obliteration of arterioles in cortical glomeruli; reduced bladder elasticity, especially in women; prostate enlargement in menReduced glomerular filtration rate and renal plasma flow; loss of bladder emptying capacity
EndocrinologicAtrophy and fibrosis; loss of vascularity; changes may be very minimalGeneral decline in secretory rate, but resting hormone blood levels may remain constant as clearance also declines
NervousLoss of brain weight and volume in most studies; loss of neurons, depending on brain area studied; loss of dendritic arbor with reduced interneuronal connectivity; interneuronal accumulation of lipofuscin and loss of organelles; neurofibrillary degeneration of neurons; accumulation of senile plaques, especially in hippocampus, amygdala, and frontal cortexInconsistent evidence of reduced blood flow; reduced metabolism of glucose and oxygen; intellectual changes
MusculoskeletalReduced muscle and bone mass; demineralization of bone; increased fat in muscles and calcium in cartilage; degeneration of cartilage; loss of elasticity in jointsLoss of muscular strength and stamina
ImmunologicInvolution of thymus, reduction of the proportion of naïve T cells, increased proportion of activated/memory T cells, decreased expression of IL-2 receptors, decreased cellular proliferative response to T-cell receptor stimulationIncreased susceptibility to cancer
Special sensesYellowing of lens in eyeLoss of auditory and visual acuity, especially night vision

Table 3. Differentiating the Common Dementias
TypeHistoryPhysical FindingsCognitive and Behavioral FunctionImaging/Laboratory Findings
Alzheimer’s diseaseGradual onset and progression; ± family historyTypically none until mid/late stagesLanguage deficits early (word finding, anomia, fluent aphasia); clues not helpful with retrieval; visuospatial deficits earlyCortical atrophy, ventricular enlargement on CT, MRI; temporal/parietal hypometabolism on PET; hypoperfusion on SPECT
Vascular dementiaAbrupt onset, stepwise decline; history of hypertension, atherosclerosisNeurologic signs and symptoms (e.g., gait abnormalities, falls, incontinence)Patchy impairment; depression, relative preservation of personality commonStroke; lacunae in basal ganglia, white matter; periventricular lesions very common, required for diagnosis if focal neurologic signs absent
HIV dementiaHIV-positive blood test; gradual onset of cognitive changesNeurologic signs and symptoms may be present (e.g., ataxia, tremor, frontal release signs)Forgetfulness, apathy, slowness, poor concentration commonElevated CSF protein; mild lymphocytosis may be present; neuroimaging nonspecific; HIV usually present in CSF
Head traumaHead injuryDepends on location of injury; dysarthria, hemiparesis commonMemory impairment usually present; impulse dyscontrol, irritability, personality change may be seen; nonprogressive unless head trauma repeated (e.g., in dementia pugilistica)Depends on location, extent of injury
Parkinson’s diseaseDementia in later stages of neurologic syndromeExtrapyramidal signs (e.g., tremor, gait disturbance, rigidity, bradykinesia)Cognitive slowing, poor recall, frontal signs (e.g., perseveration, decreased word list generation, impaired behavioral sequencing); clues helpful with memory retrievalSubcortical atrophy on CT (e.g., increased intercaudate distance, ventricular enlargement) common; global cerebral metabolism also may be diminished on PET
Huntington’s diseaseAutosomal dominant pattern of inheritance; onset generally in 30s–40s; offspring of affected parent 50% likely to be affected“Fidgeting” progres-sing to choreoathetosisPersonality change, loss of judgment, irritability early, memory impairment later; psychosis commonCT or MRI may show striatal atrophy; PET may show striatal hypometabolism
Pick’s diseaseOnset in 50s–60sFrontal release signs (e.g., snout, grasp reflex) commonPersonality change, emotional blunting, deterioration of social skills, language deficits early; memory impairment, dyspraxia laterCT or MRI may show frontal and temporal atrophy; PET may show frontal hypometabolism
Creutzfeldt-Jakob diseaseOnset in 40s–60s; 5%–15% have family history; rapid progression (i.e., 1-year course) typical; can be transmitted by corneal transplant or contact with infected brain tissue or CSFMyoclonus early, seizures later; ataxia, visual symptoms, gait disturbance variably presentNonspecific symptoms (e.g., fatigue, diminished sleep and appetite early; global cognitive deficits late)CT and MRI may be normal; EEG may show sharp, triphasic synchronous discharges at 0.5–2 Hz
