Global health reports indicate that dementia is a pressing concern affecting millions worldwide. In 2021, over 57 million individuals were living with dementia, with a majority in low- and middle-income countries. This condition, characterized by memory loss and cognitive decline, is a significant cause of disability and dependency among older populations globally. Alzheimer’s disease, a common form of dementia, contributes to a substantial portion of cases.
Dementia not only impacts individuals directly but also places a significant burden on informal caregivers, predominantly women, who provide substantial care hours. The economic cost of dementia is staggering, amounting to US$ 1.3 trillion globally, with a significant portion attributed to informal care providers. Women not only experience higher disability-adjusted life years due to dementia but also contribute significantly to caregiving responsibilities.
The syndrome of dementia encompasses various diseases that impair memory, thinking, and daily functioning. Risk factors include age, high blood pressure, diabetes, obesity, smoking, and social isolation. Dementia results from the destruction of nerve cells and brain damage, leading to cognitive decline beyond normal aging effects. It manifests in changes in mood, behavior, and cognitive function, impacting individuals, caregivers, families, and society at large.
Early signs of dementia include memory lapses, disorientation, and difficulty with daily tasks. As the disease progresses, individuals may struggle with recognizing loved ones, mobility issues, and behavioral changes. Alzheimer’s disease accounts for a significant portion of dementia cases, with other forms such as vascular dementia and Lewy body dementia also prevalent.
While there is no cure for dementia, supportive care measures can enhance the quality of life for both individuals with dementia and their caregivers. Physical activity, social engagement, and cognitive stimulation can help manage symptoms. Medications like cholinesterase inhibitors and memantine can alleviate cognitive decline, while lifestyle changes and regular health check-ups are crucial for managing the condition.
Addressing dementia as a public health priority, the World Health Organization has endorsed a Global Action Plan to guide policy-makers, international partners, and healthcare providers in tackling this growing challenge. The plan focuses on raising awareness, reducing risk factors, improving diagnosis and care, supporting caregivers, and promoting research and innovation in dementia management.
Despite the prevalence and impact of dementia, individuals living with this condition often face violations of their basic rights and freedoms. Physical and chemical restraints are sometimes inappropriately used in care settings, highlighting the need for a supportive legislative environment based on human rights principles.
In conclusion, the global health landscape recognizes dementia as a critical issue requiring concerted efforts to raise awareness, reduce risk factors, enhance care, and support individuals and caregivers affected by this debilitating condition.
