Alzheimer’s in Elder Adults - APA Format

Introduction

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder predominantly affecting older adults, characterized by declining cognitive functions, memory impairment, and behavioral changes. As the most common cause of dementia worldwide, Alzheimer’s presents significant challenges to patients, families, and healthcare systems. Understanding its epidemiology, pathophysiology, signs and symptoms, and management strategies is critical for effective care delivery.

Epidemiology of Alzheimer’s Disease

Alzheimer’s disease affects millions globally, with a rising prevalence correlated with increasing life expectancy. According to the World Health Organization (WHO), about 55 million people worldwide are living with dementia, with Alzheimer’s accounting for approximately 60-70% of cases. The incidence increases markedly after the age of 65, with a higher prevalence among women, potentially due to longer life spans. Risk factors include age, genetics, education level, cardiovascular health, and lifestyle choices (Alzheimer’s Association, 2023). The economic burden of Alzheimer's extends into billions annually, emphasizing the need for early diagnosis and management.

Pathophysiology of Alzheimer’s Disease

Alzheimer’s disease is characterized by the accumulation of amyloid-beta plaques and neurofibrillary tangles composed of tau protein within the brain. These pathological features lead to neuronal death and synaptic loss, particularly in the hippocampus and cerebral cortex—areas responsible for memory and cognition (Selkoe & Hardy, 2016). The disease progresses through stages, beginning with mild cognitive impairment and advancing to severe dementia. Neuroinflammation and oxidative stress contribute to disease progression, while genetic factors like the APOE ε4 allele increase susceptibility.

Signs and Symptoms

The clinical presentation of Alzheimer’s includes memory loss that disrupts daily life, difficulty planning or solving problems, confusion about time or place, challenges in completing familiar tasks, and changes in personality or behavior. As the disease progresses, individuals may experience difficulty speaking, swallowing, and walking, along with severe cognitive impairment (Alzheimer’s Association, 2023).

NANDA Diagnosis Related to Alzheimer’s Disease

1. Impaired Memory related to neurodegeneration as evidenced by forgetfulness, disorientation, and difficulty recalling recent events.

2. Risk for Injury related to impaired judgment and cognitive deficits, as evidenced by wandering and poor decision-making.

Medication Management

Pharmacological interventions primarily focus on symptomatic relief and slowing disease progression. Cholinesterase inhibitors such as donepezil, rivastigmine, and galantamine are commonly prescribed to improve cognitive symptoms by increasing acetylcholine levels. Memantine, an NMDA receptor antagonist, is used in moderate to severe cases to regulate glutamate activity. Polypharmacy risks necessitate careful monitoring for adverse effects, drug interactions, and adherence issues (Birks, 2018). Ongoing assessment of treatment efficacy and side effects is vital.

Care of Patients in Acute Setting and Nursing Interventions

In acute care settings, nurses play a vital role in managing agitation, confusion, and behavioral disturbances, often seen during infections or metabolic imbalances. Non-pharmacological strategies include environmental modifications, structured routines, and reassurance techniques. Safety precautions such as bed alarms and fall prevention measures are essential, as are caregiver education and emotional support. Nurses should also monitor for signs of delirium, which may complicate Alzheimer’s management (McMurtray & Mendez, 2019).

Risk Factors for Alzheimer’s Disease

Major risk factors include advanced age, genetics (e.g., APOE ε4 allele), cardiovascular disease, diabetes, hypertension, sedentary lifestyle, smoking, and low educational attainment. Evidence suggests that modifiable factors such as diet, exercise, and social engagement can influence disease onset and progression, highlighting the importance of preventive strategies (Livingston et al., 2020).

Prevention Strategies

Preventive approaches involve lifestyle modifications, including a balanced diet rich in antioxidants, regular physical activity, cognitive engagement, and managing vascular risk factors. Public health initiatives aimed at increasing awareness and early screening can facilitate timely intervention. Pharmacological prevention remains investigational, emphasizing the importance of controlling modifiable risks (Barnes & Yaffe, 2020).

Conclusion

Alzheimer’s disease remains a significant public health challenge due to its rising prevalence and profound impact on individuals and society. Advances in understanding its epidemiology, pathophysiology, and management underscore the importance of early detection, multidisciplinary care, and preventive strategies. Nurses and healthcare professionals are integral in delivering holistic care to improve quality of life for affected elders and delay disease progression.
