Introduction

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that primarily affects memory, thinking, and behavior. As one of the leading causes of cognitive decline in older adults, AD imposes a substantial burden not only on individuals but also on families and healthcare systems worldwide. Characterized by the accumulation of amyloid plaques and tau tangles in the brain, the disease leads to the deterioration of neuronal networks critical for cognitive functions. The early stages often manifest as mild forgetfulness and difficulty in performing familiar tasks, which can gradually progress to severe impairment in reasoning, communication, and daily functioning.[1].

The causes of Alzheimer’s disease are multifactorial, involving a combination of genetic, environmental, and lifestyle factors. Genetic predispositions, such as the presence of the APOE ε4 allele, have been shown to increase susceptibility, though not all carriers develop the disease. Environmental exposures, including head injuries, vascular conditions, and chronic stress, can contribute to its onset. Lifestyle factors such as diet, physical activity, and cognitive engagement play a crucial role in either mitigating or accelerating the decline. Recent studies emphasize that adopting a brain-healthy lifestyle may delay the onset or progression of cognitive deficits.[2].

Early detection and diagnosis are critical in managing Alzheimer’s disease effectively. Neuropsychological testing, imaging techniques like MRI and PET scans, and biomarker analysis of cerebrospinal fluid are commonly employed to identify cognitive impairments before they become severe. Early diagnosis allows for timely interventions, planning for future care, and participation in clinical trials. Moreover, understanding the disease trajectory helps caregivers prepare for the increasing demands associated with progressive cognitive decline. [3].

Treatment strategies for AD primarily focus on symptom management and slowing the progression of cognitive decline. Pharmacological options such as cholinesterase inhibitors and NMDA receptor antagonists can provide modest benefits in memory and daily functioning. However, these treatments do not cure the disease, highlighting the importance of comprehensive care approaches. Non-pharmacological interventions, including cognitive training, physical exercise, social engagement, and structured routines, have been demonstrated to improve quality of life and slow functional decline in affected individuals.[4].

Caregiving for individuals with Alzheimer’s disease is both challenging and essential. As cognitive decline progresses, patients may experience personality changes, agitation, and impaired judgment, requiring continuous supervision. Caregivers often face emotional, physical, and financial stress, underscoring the need for support networks, respite care, and educational resources. Societal awareness and public health initiatives aimed at supporting caregivers are vital to ensure sustained care and reduce burnout. [5].

Conclusion

Alzheimer’s disease remains a major contributor to cognitive decline among older adults, with profound personal, familial, and societal impacts. While no definitive cure exists, early diagnosis, a combination of pharmacological and non-pharmacological interventions, and robust caregiving support can slow disease progression and enhance quality of life. Ongoing research and public health initiatives are crucial in developing effective strategies to mitigate the impact of Alzheimer’s disease, offering hope to millions affected
