Examples of Alterations in - Dementia
Cognitive Systems - Alzheimer Disease (AD)
Examples of Alterations in - Parkinson disease
Neuromotor Function - Multiple Sclerosis
1) Attentional systems that provide arousal and
maintenance of attention over time
2) Memory and language systems by which info is
The Neural Systems communicated; and
Essential to Cognitive 3) Affective or emotive systems that mediate mood,
Function emotion, and intention
These core systems are fundamental to the processes
of abstract thinking and reasoning
- Alterations in CONSCIOUSNESS
Alterations in Cognitive
- Alterations in AROUSAL
Systems
- Alterations in AWARENESS
What are Data Processing Problems associated with recognizing and processing
Deficits? sensory info
, - Agnosia
- Aphasia
Types of Data Processing
- Acute confusion state (Delirium)
Deficits
- Dementia
- Alzheimer Disease
Inability or failure to recognize the former nature of
the object with the senses
Agnosia - Ppl unable to recognize object by touch
- Unable to write
- Unable to recognize speech sounds
Inability to comprehend production of language
Aphasia
(verbal or written)
- Disruption of widely distributed neural network
- Alterations in cognitive function, emotion,
perception, consciousness, awareness
Delirium - May be transient (acute) or persistent (chronic)
- Sudden or gradual onset; duration is hours to weeks
- Fluctuates; remits with treatment
- Hospitalized older adults are at greater risk
- Progressive failure of many cerebral functions
- Impairment of intellectual processes (orientation,
memory, language judgment, decision making);
usually starts with memory loss
Dementia
- Onset usually insidious but may be acute
- Chronic, slow decline; duration month-years
- Progressive
- Alzheimer disease most common cause
Classified according to etiologic factors:
- Genetics
How is Dementia - Trauma
Classified? - Tumors
- Vascular disorders
- Infections
, Grouped as:
How are Dementia Causes
- Potentially reversible
Grouped?
- Irreversible
May vary in diff types of dementias; because of
declining intellectual ability, individual may exhibit:
Clinical Manifestations of - Alterations in behavior
Dementia - Agitation
- Wandering
- Aggression
Leading cause of severe cognitive and behavioral
dysfunction (dementia) in older adults; BRAIN
SHRINKS; neurons die!!!
Alzheimer Disease - Diagnosis is made by ruling out other causes and
(Alzheimer Type using criteria developed to assist in making diagnosis
Dementia) - Definitive diagnosis can only be made at autopsy
- Clinical history, cognitive testing, course of the
illness, lab tests, and brain imaging are used to assess
progression of disease
Forms of Alzheimer - Early-onset Alzheimer disease (Familial or sporadic)
Disease - Late-onset Alzheimer disease (sporadic)
10% of cases
Risk Factors/Pathogenesis - Genetic variations/mutations in genes
for Early Onset (Familial) - Abnormal processing of a protein called APP -->
Alzheimer Disease changes in calcium signaling --> over-production of
beta amyloid --> forming plaques in brain
