dementia is a chronic or progressive syndrome, usually characterized by a more severe decline in cognitive function (that is, the ability to deal with the mind) than in the normal course of old age. It affects memory, thinking, orientation, understanding, computing, learning, language and judgment, but not consciousness.
Cognitive impairment is usually accompanied by a decline in emotional control, social behavior and mobility. Dementia is caused by a variety of diseases that primarily or secondary affect the brain. Dementia is one of the main causes of disability and dependence on others among older people around the world. It not only brings great pain to dementia patients, but also puts great pressure on their caregivers and families. Lack of understanding and understanding of dementia can lead to discrimination or obstacles in diagnosis and care. The impact of dementia on caregivers, families and society is not only physical, but may also be affected psychologically, socially and economically. Symptoms and signs of dementia affect each patient in different ways, depending on the impact of the disease and the individual situation of the patient before the disease. The signs and symptoms associated with dementia can be roughly divided into three stages.
early stage: because dementia is a gradual onset, it is often ignored in the early stage of dementia.
common symptoms include: forgetfulness, loss of time, loss of time Including trance and repeated questions
terminal: patients with late dementia are almost completely dependent on other people's care and almost completely inactive. Severe memory impairment occurs, and physical signs and symptoms become more and more obvious.
symptoms include inability to recognize when and where relatives and friends have difficulties in self-care, increasing need for assistance in walking difficulties and experiencing more behavioural changes, which may include multiple different forms or causes of common forms of aggressive dementia.
Alzheimer's disease is the most common form of dementia and may account for 60-70% of the causes of dementia. Other major forms include vascular dementia, Louis body dementia (abnormal accumulation of proteins in nerve cells) and a group of diseases that lead to frontotemporal dementia (deterioration of the frontal lobe). The boundaries between different forms of dementia are not clear, and mixed forms of dementia often exist at the same time. Treatment and health care do not currently have a cure for dementia or change its course of development. Countless new treatments are at different stages of clinical trials. However, much remains to be done to support and improve the lives of dementia patients, their caregivers and their families.
the main objectives of dementia care are:
early diagnosis optimizes physical, cognitive, mobility and health status detection and treatment of concomitant physical disease detection and treatment of behavioral and psychological symptoms to provide caregivers with information and long-term support for risk factors and to ensure that existing evidence proposes some objectives for prevention efforts. This includes coping with risk factors for vascular disease, such as diabetes, middle-aged high blood pressure, middle-aged obesity, smoking and lack of physical exercise. The social and economic impact of dementia is enormous, including direct medical costs, direct social costs and informal care costs. In 2010, the total global social cost of dementia was estimated at $604 billion, or 1.0 per cent of the world's gross domestic product (GDP), or 0.6 per cent if only direct costs were taken into account. Total costs range from 0.24 per cent of GDP in low-income countries to 1.24 per cent of GDP in high-income countries. Effects on families and caregivers dementia puts great pressure on families and their caregivers, including physical, mental and financial stress. The health, social, financial and legal systems need to provide support to patient families and caregivers.
