"Dementia: A Comprehensive Review of Pathophysiology, Diagnosis, And Management"

Abstract

Introduction:
Dementia is a progressive neurodegenerative disorder marked by a decline in memory, cognition, and behavioral functioning, ultimately leading to loss of independence. With Alzheimer’s disease being the most prevalent form, dementia presents in various subtypes, each with distinct clinical and pathological features.

Objectives:
This review aims to comprehensively explore the types of dementia, elucidate the underlying pathophysiology, identify key risk factors, examine current diagnostic and therapeutic strategies, and highlight future directions in research and management.

Methods:
An extensive literature review was conducted using peer-reviewed articles, clinical guidelines, and epidemiological studies related to dementia. Data were analyzed to identify trends in disease prevalence, diagnostic advancements, and therapeutic approaches.

Results:
Alzheimer’s disease accounts for 60–80% of dementia cases, characterized by amyloid-beta plaques and neurofibrillary tangles. Other forms include vascular dementia, Lewy body dementia, and frontotemporal dementia. Major risk factors include aging, cardiovascular conditions, depression, genetic mutations, and environmental influences. Advances in biomarkers, neuroimaging, and molecular diagnostics have enhanced early detection, though diagnostic challenges remain. Current pharmacological treatments provide symptomatic relief but fail to halt disease progression. Non-pharmacological interventions and caregiver support significantly improve patient quality of life.

Conclusion:
The global burden of dementia is escalating, with cases projected to surpass 130 million by 2050. Tackling this public health crisis requires early diagnosis, integrated care, supportive policies, and sustained research into disease-modifying therapies. Future breakthroughs in diagnostics and treatment offer hope for improved outcomes and quality of life for patients and caregivers alike.
