Dementia is an umbrella term used to explain the gradual decline in multiple areas of functions, which includes thinking, perception, communication, memory, languages, reasoning, and the ability to function (Harrison-Dening 2013). Worldwide, 47.5 million people have dementia and there are 7.7 million new cases every year. Alzheimer's disease is the most common cause of dementia and may contribute to 60–70% of cases. (Alzheimer's society 2014). The complexity of dementia presents a number of behavioural challenges to those who live with dementia and their care providers. Aggressive behaviour seems to be one of the most prevalent challenging behaviours in the different stages of dementia (Weitzel et al 2011). As acute care settings are not the best places for people afflicted with dementia , it is necessary to empower the hospitalised people with dementia and their family members. As nurses are often the central core of care, they should have the potential of positive long-term effect on the lives of people with dementia (Harrison-Dening 2013). Inadequate training, lack of specialised education, negative attitudes and poor practice development can precipitate a failure in the delivery of high-quality care for the hospitalised dementia people (Chater & Hughes 2012).
Brain Activity Changes
Dementia progressively affects almost all brain functions, including the control of motor function (Plosker & Gauthier 2009). The cell damage leads to tissue shrinkage and limited function in the brain's frontal and temporal lobes, which control emotions, planning, and reasoning, judgment, speaking, understanding and controlling movements (Narvid et al 2009). Consequently people with dementia may suffer the difficulty of solving p...

- Curing Dementia Syndrome There is no cure for dementia syndrome (Alzheimer 's Association, 2015). Dementia is progressive, which means that as time goes on it will only get worse (Draper, 2004). Once a patient loses a memory or function they will never get it back. Treatments for the syndrome will only help alleviate some of the symptoms not treat dementia or slow its progression. Treatments include medications, usually for the disease that had caused the dementia. Treatment also includes different therapies.... [tags: Alzheimer's disease, Dementia, Patient]

- Dementia is a difficult disease to understand and handle. A major problem involving these patients are caregivers that are not properly trained and educated to care for people with the disease resulting in issues such as neglect and abuse. To better understand the patient, you should first understand the disease itself. According to Wayne, White, and Smith (2015), “dementia is caused when connections in the brain are lost due to inflammation, trauma, or disease and eventually the neurons die and dementia is the result.” Although some believe that dementia may be genetic, research suggests that it has more to do with your lifestyle, heredity, and environment....
