Explanation

Dementia is a general term for a progressive and irreversible decline in intellectual functions, including memory, thinking, and language.
It is not a normal part of aging, but its prevalence increases significantly with age, affecting a large percentage of the elderly population.
Alzheimer's disease is the most common cause of dementia.
Unlike delirium, consciousness is typically not affected in the early to moderate stages of dementia.

Option A: Insomnia is a sleep disorder characterized by difficulty initiating or maintaining sleep. While it can affect cognitive performance, it is not a primary memory disorder.
Option C: Dyspnoea is the medical term for shortness of breath. It is a symptom of respiratory or cardiac disease, not a cognitive or memory disorder.
Option D: Dystrophy refers to the progressive degeneration of a tissue or organ. A common example is muscular dystrophy, which affects muscle tissue, not cognitive function.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common memory disorders in the geriatric population as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in the early detection of cognitive changes in older adults by using screening tools like the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment (MoCA).
For patients with dementia, ensuring safety is a top priority. This includes implementing fall precautions, preventing wandering, and managing behavioral symptoms like agitation.
It is vital for nurses to differentiate between dementia and delirium, as delirium is often a medical emergency caused by an underlying acute issue (like an infection or medication side effect) and is frequently reversible with prompt treatment.

How to Approach the Question

First, analyze the question to identify the key concepts: 'memory disorder' and 'older adults'.
Next, evaluate each option based on its medical definition.
Option A, Insomnia, is a sleep disorder.
Option C, Dyspnoea, is difficulty breathing.
Option D, Dystrophy, is tissue degeneration.
Option B, Dementia, is a well-known syndrome involving memory loss that primarily affects the elderly.
