"Dementia is a syndrome due to disease of the brain, usually of a chronic or progressive nature, in which there is disturbance of multiple higher cortical functions, commonly accompanied, and occasionally preceded, by deterioration in emotional control, social behaviour, or motivation"[1].
The prevalence of dementia is increasing worldwide. In year 2015, the global prevalence of dementia was estimated to be 46.8 million [2]. Dementia prevalence is predicted to almost double every 20 years, to 74.7 million in 2030 and 131.5 million in 2050. The incidence of dementia in 2015 was estimated to be 9.9 million [2]. Age-standardized prevalence of dementia among population aged 60 years or more was 5%–7% over the world [3].
A new emergence during the new millennium is the 'greying' of the developing countries [4]. In 2015, 58% of all people with dementia lived in low and middle income countries (according to the current World Bank classification), rising to 63% in 2030 and 68% in 2050. In 2015, the prevalence of dementia in Asia was 22.9 million [2]. The standardised prevalence (using Western Europe as the standard population) for population aged 60 years or …show more content…
Studies have established a statistically significant correlation between caregiver burden and the ability of the patient to cope with the activities of daily living [18] and patient's problematic behaviour [19]. It is well established that the symptoms of dementia are an important cause of caregiver burden and stress [29]. Recent meta-analysis have shown that physical dependency is positively associated with depression of the caregiver [29]. The relationship between cognitive impairment and burden is less clear. No direct relationship was found in some studies [30, 31]. In a study conducted among 77 dementia caregivers in Sri Lanka, there was no significant association between the presence of behavioural and psychological symptoms of dementia and care-burden
