NURS 330: Treas Cognition Reading

Definition: Osteoporosis is defined as a loss in bone mineral density, which significantly increases the risk of fractures.
Prevalence: It affects an estimated 10 million Americans.
Advanced Cases: In advanced osteoporosis, bones may become so porous that they can fracture spontaneously due to normal stress from weight-bearing.
Risk Factors for Osteoporosis:
- Age: The risk increases with advancing age.
- Gender:
- Females are at greater risk due to typically lower bone density compared to males.
- Hormonal changes, particularly at menopause, and inadequate calcium intake, increase risk.
- Lifestyle Factors:
- Cigarette smoking.
- Moderate to heavy alcohol consumption.
- Lack of weight-bearing exercise.

Overview: Dementia is characterized by an irreversible progressive decline in mental abilities, affecting approximately 1 in 5 adults older than 70 years.
Key Point: Dementia is not a normal result of aging; rather it is common but not typical.

Condition Characteristics:
- It is the primary form of dementia, and it is progressive in nature.
- Affects about half of adults aged 85 and older.
- Research is ongoing, particularly by the National Institute on Aging, for diagnostic tools such as a blood test for a specific brain protein that predicts Alzheimer’s before symptoms manifest.

U.S. Preventive Services Task Force (2020):
- Does not recommend routine screening for dementia but acknowledges that early diagnosis allows for anticipation of future problems.
- Some dementias may be treatable (e.g., those due to medication toxicity, sensory deficits, and certain physiological problems).
Differentiated Assessment: Differentiating dementias from delirium (acute confusion) and depression is critical.

Symptoms:
- Dementia involves memory impairment and disturbances in at least one additional area of cognition, including:
- Aphasia: Loss of ability to communicate.
- Apraxia: Loss of ability to perform purposeful movements.
- Agnosia: Impaired ability to recognize or identify objects, which can lead to not recognizing family members or one’s own reflection.
- Disturbance in executive functioning.
Effects on Daily Functioning:
- Affects memory, cognition, communication, self-care abilities, mood, personality, and behavior.

Mental Status Examinations:
- The Sweet 16: 16 oral questions that evaluate orientation, registration, attention, and short-term memory.
- Mini Mental State Examination (MMSE): Assesses various mental abilities including memory, attention, and language.
- Ultrabrief screening: Includes tasks such as reciting the months backward and stating the current day.

Impaired Verbal Communication related to an irreversible, progressive decline in mental abilities.
Fear related to difficulties in speaking and understanding communication.
Key Point: It is vital to recognize that a patient's reality may be distorted, and they behave in the only ways they can.

Safe Environment: Create an atmosphere that fosters safety and security for those with dementia.
Communication Strategies:
- Use short, simple sentences, focusing on one idea at a time.
- Avoid vague comments and provide clarity in responses.
- If the patient does not understand, repeat exact phrases they struggled with.
- Activities should be person-centered, engaging in cognitive tasks appropriate for their age group.
Supervision and Assistance: Provide sufficient supervision (sometimes 24/7) and help with activities of daily living (ADLs) such as bathing and toileting.
Caregiver Support: Assess and provide support for caregivers, emphasizing reinforcement of social involvement and activities.

Normal Aging Changes Affecting Communication:
- Information processing is generally slower; thus, allow older adults time to respond.
Check for Sensory Deficits: Assess hearing and vision before engaging in communication; allow for lip-reading if necessary.
Observing Nonverbal Communication: Pay attention to body language, emotional reactions, and coherence in speech patterns.
Variable Responses: Recognize that coherence does not always align with understanding. Monitor for alterations during conversations, and if confusion arises, assess mental status to determine the best communication course.

Educate Family Members: Family members often take on the primary caregiver role, and they risk physical and mental health decline themselves.
Intervention Types:
- Offer educational resources about dementia and psychotherapeutic support.
- Provide crisis management services and respite care.
- Faith-based spiritual assistance may also be beneficial.

Distinguishing Factors: Cognitive disorders like delirium and dementia can be confused with depression due to overlapping symptoms.
Delirium Defined:
- An acute, reversible disturbance of consciousness and cognition that may arise from various underlying medical conditions—including potential preventable cases (30%)—with an emphasis on patient safety and prompt intervention.

Components of General Assessment:
- Personal Identity: Establishing trust through early patient identification-related dialogue.
- Appearance and Behavior: Includes posture and speech analysis to gauge health status.
- Mental State: Considers alertness, coherence, spatial orientation, and communication problems as indications of neurological health.

Types of Sensory Deficits:
- Visual and auditory deficits are the most common, and each has unique effects and potential remedies.
Visual Deficits:
- Conditions: Myopia, hyperopia, presbyopia, astigmatism, cataracts, glaucoma, among others.
- Consequences: Increased fall risk, social isolation, independence loss.
Auditory Deficits:
- Conditions: Conduction deafness, sensorineural hearing loss, presbycusis, central deafness.
- Consequences: Risk for injury from missed warnings, depression, social isolation.

Visual Deficits Solutions:
- Ensure eyeglasses are accessible and in good repair, promote regular eye exams, remove environmental obstacles.
Auditory Deficits Solutions:
- Encourage use of hearing aids, inspect ear canals for cerumen impaction, provide clear communication.

Common Challenges During Bathing:
- Agitation due to fear or pain during bathing can be mitigated by addressing comfort needs and utilizing adaptations like bag baths.
- Key considerations include not enforcing daily baths or traditional methods if resisted; alternative methods should be explored for patient comfort.

Protective Measures:
- Encourage physical activity, intellectual engagement, interaction with family and friends, a healthy diet, control of risk factors for cardiovascular health, and adequate sleep.

Importance of Routine and Familiarity: Establishing a consistent framework for care leads to better patient outcomes; it fosters predictability and stability for those living with cognitive conditions.
