Amblyopia

Disease Description (Causes and Symptoms)

• Definition: A condition in which physiological reserve (reserve capacity) for coping with internal and external stressors is reduced, referring to an abnormal aging state that is functionally and pathophysiologically more vulnerable than normal aging.
• Main pathophysiology: A combination of reduced reserve capacity in multiple organ systems (musculoskeletal, immune/inflammatory, endocrine, nervous, etc.), decreased muscle mass and strength (sarcopenia), chronic low-grade inflammation, hormonal changes (decreased sex hormones and IGF-1), malnutrition, and changes in the neuromuscular junction contribute to the condition.
• Main causes (risk factors): Advanced age, chronic diseases (heart failure, COPD, diabetes, etc.), malnutrition and weight loss, reduced physical activity, polypharmacy, depression and cognitive decline, and repeated hospitalizations and acute illnesses.
• Main symptoms: Easy fatigue and lethargy, slower walking (reduced mobility), decreased muscle strength (especially in the lower limbs), weight and muscle-mass loss, loss of appetite, dizziness and falls, and reduced activity; rapid deterioration may occur after an infection or minor illness.

Treatment Methods and Precautions

• Assessment and correction of causes: Conduct a comprehensive geriatric assessment (CGA) to evaluate nutritional status, sarcopenia, cognition and mood, fall risk, medication list, and chronic disease management status, and provide treatment according to the causes.
• Exercise therapy: Multicomponent exercise (resistance exercise combined with balance and aerobic exercise) is the most effective. An individualized program that includes resistance exercise (strengthening) at least 2–3 times per week is recommended.
• Nutritional management: Increase the recommended protein intake (generally targeting 1.2–1.5 g/kg/day, adjusted according to the situation), provide adequate calorie supplementation, and provide supplementation in cases of vitamin D deficiency. Nutritional supplementation in cases of loss of appetite or undernutrition requires cooperation with a dietitian.
• Medication and medical management: Review polypharmacy and reduce unnecessary medications (be cautious of medications that cause emotional or cognitive side effects), optimize management of chronic diseases (such as heart failure and diabetes), and treat underlying conditions such as depression, dementia, and Parkinson disease.
• Inpatient and acute-phase management: Maintain early mobility and rehabilitation whenever possible, and avoid excessive absolute rest (bed rest).
• Drug treatment: Currently, no specific medication is standard treatment, and hormones and anti-inflammatory drugs are used selectively and on a limited basis (expert judgment is required).
• Complications and precautions: There is an increased risk of falls and fractures, infections and pneumonia, functional decline and increased dependence, and mortality. Prompt response to acute illnesses is important. In overall management, an individualized plan that reflects the patient's values and goals (needs and lifestyle) is recommended.

Checklist Before an Outpatient Visit (Items to Prepare and Review, and Sample Questions)

• Items to prepare/bring:
  • A list of all currently taken medications (including prescription drugs, OTC medications, and supplements) or medication bags
  • Recent weight records (if possible, changes compared with 6–12 months ago) and fall records (frequency and circumstances)
  • Changes in activity level, walking speed, or gait-related observations (ability to perform household tasks and whether assistive devices are used)
  • Recent hospital medical records and test results (including blood tests and imaging), and caregiver information if a caregiver can accompany the patient
• Tests that may be useful to check before the visit (after consulting with a doctor):
  • Basic blood tests (CBC, electrolytes, liver and kidney function), thyroid function, vitamin B12, vitamin D, albumin/nutritional markers, inflammatory markers (CRP), and iron assessment if needed
  • Functional assessments: usual gait speed, grip strength, SPPB (Short Physical Performance Battery), and fall-risk assessment
• Examples of information to explain to the doctor during the outpatient visit:
  • When and how your recent weight changed (intentional or unintentional)
  • Whether you have recently had an infection, hospitalization, or medication change
  • Whether your ability to perform activities (such as eating, washing your face, and getting dressed independently) has changed

Examples of General Questions to Ask the Doctor

• "Based on my current condition, what is the severity of frailty (mild/moderate/severe)?"
• "What are the priorities I should change first in daily life (exercise, nutrition, or medication adjustments)?"
• "Are there any medications I am taking that should be stopped or have their dosage reduced? What are the side effects?"
• "How should I start nutritional supplementation (such as protein and vitamin D), and how long should I continue it?"
• "What is my prognosis? What indicators should be monitored to reduce the risk of deterioration?"

Examples of Disease-Specific Questions

• "Could you give me specific information about a strength and balance exercise program that I can start safely (number of sessions, intensity, and weekly frequency)? Do you recommend physical therapy or community exercise programs?"
• "Could you assess whether any of my current medications (for example, sleeping pills, analgesics, or antipsychotics) may be contributing to worsening frailty? If they should be reduced, what alternatives are available?"
