Stroke survivors often require long-term care due

A

to physical and psychological symptoms that impair independent functioning

30
Q

What happens if you receive left hemisphere damage

A

affects speech and language proficiency and physical movement of right half of body

31

A

impairs judgment and short term memory, increases impulsivity, affects visual-spatial skills

32
Q

What happens to stroke survivors

A

frustrated and depressed by difficulties experienced
cognitive skills decline due to chronic or sporadic cardiovascular events affecting blood flow to the brain
uneven deterioration of intellectual activities
physical and cognitive symptoms may be impaired

33
Q

What is a neurodegenerative disorder

A

declining brain due to atrophy and loss of neurons
Vary:
age of onset
skills of affected
course of disorder

34
Q

What is Alzheimers

A

Dementia involving memory loss in cognitive and adaptive functioning
5 million Americans
6th leading cause of death
risk increases with age, can attack at 30,40, or 50

35
Q

What are some characteristics of Alzheimer’s

A

-progressive decline in cognitive, physical, and social functioning
-early symptoms: memory dysfunction, irritability, cognitive impairment
-other symptoms: social withdrawal, depression, apathy, delusions, impulsive behaviors, neglect of personal hygiene
-no cure

36
Q

What are some memory loss factors for Alzheimers

A

With age, neurons are gradually lost, the brain becomes smaller, and info is processed more slowly(normal process)
many adults experience minimal decline because with age, the brain reorganizes itself
acute conditions such as infection or reaction to prescription drugs

37
Q

What are some abnormal brain structures with Alzheimers

A

increased atrophy of brain tissue
neurofibrillary tangles: twisted masses of protein fibers found inside nerve cells
Senile plaques: composed of parts of neurons surrounding a group of proteins called beta-amyloid deposits
tangles and plaques disrupt transmission between neurons

38
Q

What is the etiology of Alzheimers

A

genetics and environmental
Twins found heritability is high but environmental influences also important
Autosomal-dominant Alzheimers disease
APOE-e4 gene as a risk gene

39
Q

How to prevent Alzheirmers

A

maintaining a healthy cardiovascular system can reduce the risk
changes in lifestyle may slow the progression
Anti-inflammatory drugs may slow the accumulation of proteins implicated in Alzheimer’s

40
Q

What is Lewy body Dementia

A

visual hallucinations, cognitive fluctuations, atypical movements
second most common(30%)
results in progressive cognitive decline and milder Parkinsons movement symptoms
more rapid onset than AD(Alzheimer’s), but similar onset

41
Q

What are some characteristics of Lewy Body Dementia

A

-significant fluctuations in attention and alertness
-recurrent detailed visual hallucinations
-frequent falls, a shuffling gait, muscular rigidity, and slowed movement
-sleep disturbances
-depression is common

42
Q

How is LBD similar with other neurocognitive disorders

A

same irregularities in neurons seen in Parkinson’s, LBD diagnosed when the cognitive decline begins within a year of Parkinson’s like motor symptoms
have plaque/tangles seen in AD
data is compromised due to overlap of symptoms in other dementia
confirmed through autopsy

43
Q

What is frontotemporal lobar degeneration

A

brain degeneration in the frontal and temporal lobes resulting in a progressive decline in language and behavior
the fourth leading cause of dementia

44
Q

What are the symptoms depending on in Frontotemporal lobar degeneration

A

changes in behavior and personality
difficult using words or naming objects
difficulty forming words and using language

45
Q

What are some characteristics of Frontotemporal Lobar Degeneration

A

midlife
complex diagnosis and treatment
significant genetic component
significant genetics component

46
Q

What is Parkinsons

A

progressive disorder chatacterized by poorly controlled moto movements
2nd most common(500,000)

47
Q

What are the 4 common symptoms of parkinsons

A

tremor of hands, arms, legs, jaw, or face
rigidity of limbs and trunk
slowness in initiating movement
impaired balance and coordination

48
Q

How to treat parkinsons, and how it combined with Lewy body

A

motor area of the brainstem and accelerated aging of neurons, and loss of dopamine
medication but there are severe side effects
surgical procedures on brain or implantation of electrodes to stimulate areas of the brain

49
Q

What is Huntingtons

A

a genetically transmitted degenerative disease characterized by involuntary twitching movements and eventual dementia
age of onset is variable, ranging from childhood to late life
early symptoms: twitch in fingers or facial grimaces

50
Q

How does Huntington progress

A

-abrupt repetitive movements
-changes in personality and emotional stability
-cognitive deficits and dementia
-severe motor and cognitive impairments
-major depression
-no cure, but can be reduced by medication

51
Q

What is AIDS Dementia complex symptoms

A

Dementia may be the first sign of AIDS
-inability to concentrate, difficulty with complex mental tasks, tremors, poor balance, and increased apathy and lethargy
ADC among AIDS people are 10-20%

52
Q

What is Meningitis

A

inflammation of the membrane surrounding the brain and spinal cord
symptoms vary with age
can result in the destruction of brain tissues
result of virus/bacteria

53
Q

What is Encephalitis

A

brain inflammation, many make a complete recovery
result of virus/bacteria

54
Q

What is Epilepsy

A

a chronic disorder characterized by seizures resulting from uncontrolled electrical discharge in the brain
most common neurological disorder
1-2% of pop, 2.7 million
Etiology: tumors, injury, degenerative disease, substance abuse
medication not always helpful

55
Q

What are some major interventions

A

-rehabilitative techniques
-medical techniques
-cognitive behavioral techniques
-lifestyle changes
-environmental support
-caregiver support

56
Q

What type of rehabilitation can be done

A

must be comprehensive and sustained
physical, occupational, speech, and language therapy
individual must be committed
depression, pessimism, and anxiety can stall progress
therapy provided by robotic devices show promising results

57
Q

How does medication help

A

can prevent, control, or reduce symptoms
target physical symptoms or cognitive decline
help control comorbid emotional problems
must balance positive and negative effects

58
Q

What are some cognitive behavioral approaches

A

psychotherapy can enhance coping and participation in rehabilitation efforts
can also be used to reduce the frequency and severity of problems behaviors or to improve functional skills

59
Q

How can life style changes help

A

prevent or reduce progression of neurocognitive disorders
mental stimulation to prevent and reduce cognitive decline
mental exercises can improve memory, reasoning ability, and info processing speed

60
Q

How can environmental support help

A

neurodegenerative disorder involving dementia are irreversible and can be best managed with supportive environment
modifying environment can increase safety and comfort while decreasing confusion and agitation

61
Q

How can caregiver support help

A

family and friends who provide care in need of support
may feel overwhelmed, helpless, frustrated, or angry
