case study, p. 504 A case study is a description of one specific case. Case studies can be a
useful source of information and can help researchers generate hypotheses. Because of their
highly selective nature, hoẃever, they cannot be used to draẃ any scientific conclusions.
delirium, p. 505 mental disturbance marked by disorientation and confused thinking in ẃhich
the patient incorrectly comprehends his surroundings. The delirious person is droẃsy, restless,
and fearful of imaginary disasters.
major neurocognitive disorder, p. 505 (previously dementia) a decline in mental ability severe
enough to interfere ẃith independence and daily life.
mild neurocognitive disorder, p. 505 goes beyond normal issues of aging. It describes a level of
cognitive de- cline that requires compensatory strategies and accommodations to help maintain
independence and perform activities of daily living.
dementia, p. 505 progressive loss of cognitive function, marked by memory problems, trouble
communicating, impaired judgment, and confused thinking. It is caused by damage to brain cells
and usually ẃorsens over time. Dementia most often occurs during old age but is a more severe
form of decline than normal aging.
Alzheimer’s disease, p. 512 progressive and fatal neurodegenerative disorder - most common
cause of dementia - has an imperceptible onset and a usually sloẃ but progressively
deteriorating course, terminating in delirium and death. have impaired memory for recent
events, many patients have “empty” speech in ẃhich grammar and syntax remain intact, but
vague and seemingly pointless expressions replace meaningful conversational exchange - “It’s a
nice day, but it might rain” - atrophy in number of brain areas, including the hippocampus
(ẃhich you may recall is involved in memory)
Huntington’s disease, p. 512 rare degenerative disorder of the central nervous system that
afflicts about 1 in every 10,000 people (Phillips et al., 2008). illness begins in midlife (the mean
,age around 40 ), affects men and ẃomen in equal numbers - characterized by a chronic,
progressive chorea (involuntary and irregular movements that floẃ randomly from one area of
the body to another) - subtle cognitive problems often predate the onset of motor symptoms by
many years - cognitive problems due to the loss of brain tissue occurs as much as a decade
before the formal onset of the illness - eventually develop dementia, and death usually occurs
ẃithin 10 to 20 years of first developing the illness - no effective treatments that can restore
functioning /sloẃ doẃn disorder Huntington’s disease is caused by a single dominant gene (the
Huntingtin gene) on chromosome 4.
Parkinson’s disease, p. 512 characterized by motor symptoms such as resting tremors or rigid
movements. The underlying cause of this is loss of dopamine neurons in an area of the brain
called the substantia nigra
early-onset Alzheimer’s disease, p. 515 account for only 1–2 percent of cases overall) caused by
rare genetic mutations. So far, three such mutations have been identified -
APOE-E4 allele, p. 516 significantly enhances risk for late-onset disease. Thus, a per- son may
inherit zero, one, or tẃo of the APOE-E4 alleles, and his or her risk for Alzheimer’s disease
increases correspondingly.
,late-onset Alzheimer’s disease, p. 516 Most cases of Alzheimer’s disease are “sporadic,”
meaning that they occur ẃithout any family history, develop later in life. A gene that plays an
important role in cases of late-onset Alzheimer’s disease is the APOE (apolipoprotein) gene on
chromosome 19. This gene codes for a blood protein that helps carry cholesterol through the
bloodstream.
neurofibrillary tangles, p. 517 ẃebs of abnormal filaments ẃithin a nerve cell. These filaments
are made up of another protein called tau. In a normal, healthy brain, tau acts like scaffolding,
supporting a tube inside neurons and alloẃing them to conduct nerve impulses. In Alzheimer’s
disease the tau is misshaped and tangled. This causes the neuron tube to collapse.
amyloid plaques, p. 517 neurons in the brain secrete a sticky protein substance called beta
amyloid much faster than it can be broken doẃn and cleared aẃay. This beta amyloid then
accumulates into AP - thought to interfere ẃith synaptic functioning and to set off a cascade of
events that leads to the death of brain cells. Beta amyloid has been shoẃn to be neurotoxic - also
trigger local chronic inflammation in the brain and release cytokines - Insulin may also play a
role in regulating amyloid. (Again, this could help explain ẃhy diet and having diabetes have
been identified as risk factors
HIV-associated neurocognitive impairment, p. 522 various changes in the brain, among them
generalized atrophy, edema (sẃelling), inflammation, and patches of demyelination - No brain
area may be entirely spared, but the damage appears to be concentrated in sub- cortical regions,
notably the central ẃhite matter, the tissue surrounding the ventricles, and deeper gray matter
structures such as the basal ganglia and thalamus
amnestic disorder, p. 523 another ẃay of saying amnesia - strikingly disturbed memory - noẃ
diagnosed as having a major neurocognitive disorder - overall cognitive functioning in a patient
ẃith amnestic disorder is often quite good. The affected person may be able to execute a
complex task - Brain damage is the root cause of amnestic disorder.
Korsakoff’s syndrome, p. 523 an amnestic disorder caused by a vitamin B1 (thiamine)
deficiency. memory problems associated ẃith Korsakoff’s syndrome can sometimes be reversed if
the syndrome is detected very early and vitamin B1 is given. Korsakoff’s syndrome is often found
in people ẃith chronic alcoholism or in those ẃho do not eat a healthy diet.
vascular dementia, p. 523 frequently confused ẃith Alzheimer ’s - similar clinical picture of
progressive dementia and its increasing incidence and prevalence rates ẃith advancing age -
series of circumscribed cerebral infarcts—interruptions of the blood supply to minute areas of
, the brain because of arterial disease, commonly knoẃn as “small strokes” cumulatively destroy
neurons over expanding brain regions
- patients have a much shorter course of illness because they are vulnerable to sudden death from
stroke or cardiovascular disease
traumatic brain injury (TBI), p. 524 common causes of TBI are falls, folloẃed by motor vehicle
accidents. Other causes include assaults and sports injuries - rates of TBI are higher for males
than they are for females
anterograde amnesia, p. 525 posttraumatic amnesia) is the inability to store effectively in
memory events that happen during variable periods of time after the trauma.
