一位82歲女性在家屬女兒陪同下前來診所進行年度老人體健。女兒表達擔憂並說：「我媽媽有時會花比較長的時間才想起朋友的名字。但最近，她在雜貨店無法計算找零，在她每週都去的市場裡徹底迷路，甚至試圖在不穿外套的情況下走進下雪的室外。這只是變老而已嗎？」護理師的哪項回應最準確地區分了正常老化與病態衰退？
An 82-year-old female presents to the clinic for an annual geriatric wellness exam, accompanied by her daughter. The daughter expresses concern, stating, "My mother sometimes takes longer to remember her friends' names. Recently, she couldn't count her change at the grocery store, got completely lost in the market she visits weekly, and tried to walk outside in the snow without a coat. Is this just getting old?" Which response by the nurse accurately differentiates normal aging from pathological decline?
- A“These are all expected physiological changes associated with advanced age; we can recommend cognitive puzzles to keep her sharp.”「這些都是與高齡相關的預期生理變化；我們可以建議認知拼圖遊戲來保持她的敏銳度。」
- B“Taking longer to recall names is a sign of severe dementia, but getting lost in a store is a normal cognitive slowing of older age.”「回想名字較慢是嚴重失智的徵兆，但在商店迷路是高齡認知減緩的正常現象。」
- C“Occasional forgetfulness with names is normal, but getting lost in familiar places and losing the ability to calculate change indicate cognitive impairment needing medical evaluation.”✓ 正解「偶爾忘記名字是正常的，但在熟悉的地方迷路以及失去計算找零的能力，表示認知障礙需要醫療評估。」
- D“At age 82, structural brain atrophy normally causes older adults to lose sensory awareness of cold weather and judgment surrounding finances.”「在 82 歲時，腦部結構萎縮通常會導致老年人喪失對寒冷天氣的感覺意識以及對財務的判斷力。」
本題測驗老人醫學的健康促進：鑑別「正常老化」與「失智症等病態衰退」。根據 AGS (美國老年醫學會) 指引，大腦皮質萎縮確實是老化的正常生理變化，這會導致訊息處理速度變慢，因此老年人「偶爾花較長時間回想名字或詞彙」是正常的良性健忘。然而，當認知受損影響了「複雜日常生活活動 (IADLs，如算錢與財務管理)」、在極度「熟悉的路線迷向 (Spatial disorientation)」，以及「失去安全判斷力 (如雪天不穿大衣)」時，這明確地跨越了惡化界線，是阿茲海默症等失智症的病理特徵（選項C正確）。選項A與D將這些嚴重的認知與判斷力喪失歸因於自然老化，會導致病患錯失早期診斷與社會支持介入的黃金期。選項B則將良性現象與病態現象顛倒。
This item tests health promotion in geriatrics: differentiating normal aging from pathological decline such as dementia. According to American Geriatrics Society (AGS) guidelines, cortical atrophy is indeed a normal physiologic change of aging that slows information processing, so it is normal for older adults to occasionally take longer to recall names or words, which represents benign forgetfulness. However, when cognitive impairment affects complex Instrumental Activities of Daily Living (IADLs, such as calculating money and financial management), causes spatial disorientation in highly familiar settings, and results in loss of safety judgment (such as going out in the snow without a coat), the line has clearly been crossed into the pathological features of Alzheimer's disease and other dementias (option C is correct). Options A and D attribute these severe losses of cognition and judgment to natural aging, which would cause the client to miss the golden window for early diagnosis and social support. Option B reverses benign and pathological phenomena.
世界兩國針對正常老化與失智的區分定義完全一致（多半採用 MMSE 與 AD8 評估量表的核心概念）。這類「區分何為正常老化」在預防醫學領域中是預防跌倒與走失的第一道防線。
