Abstract

Introduction:

Quality of life (QoL) in dementia care can be enhanced through nonpharmacological interventions. This systematic review and meta-analysis aimed to evaluate the effectiveness of such interventions across demographic groups in Saudi Arabia.

Methods:

A systematic search identified 11 studies assessing sensory stimulation, mindful walking, functional independence, caregiver support, and public awareness interventions. Data were extracted on study design, population, and outcome measures. Three outcome studies were narratively synthesized.

Results:

Sensory stimulation interventions (n = 62) showed the strongest behavioral improvements, with a large effect size (Hedges' g = -2.03). Data from other studies were insufficient for quantitative pooling, and no formal meta-regression or heterogeneity analyses were conducted.

Discussion:

Findings suggest that behavioral and psychological interventions tailored to older adults yield the most significant QoL benefits. Caregiver support and awareness programs offer important supplementary benefits, although limited data restrict broader generalizations.

Conclusion:

Non-pharmacological interventions, particularly those targeting behavioral and psychological outcomes, improve QoL in dementia care. However, further high-quality studies with comprehensive outcome reporting are needed to strengthen the evidence base and guide populationspecific strategies.

Restorative Care

Restorative Care

Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Alzheimer's Disease: Treatment

Alzheimer's Disease: Treatment

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Dementia

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.

Alzheimer Disease l: Introduction

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
