Dementia the Result of the Disorders of Brain

Many patients of dementia experience changes in personality and such behavioral issues as delusions, hallucinations, and agitation. Memory loss is an important indicator of dementia, though a person suffering from loss of memory may not necessarily have dementia. Dementia is one of the most common diseases among old people all over the world, though a considerable number of people below the age limit of 65 years are the patients of dementia. In the UK alone, as many as 700,000 people suffer from dementia. The risk of an individual to experience dementia increases as he/she ages. After the age of 65 years, the risk of dementia becomes two-fold every five to six years. A lot of old people suffer from dementia, and cognitive impairment is frequently encountered in the setting of acute care. This is not likely to change in the near future as demographic studies predict a steady increase in the average age of the population over the course of this century and a rise in the number of people with dementia that reaches almost one million in the UK by 2020 (Burgess, Page, and Hardman). There has occurred a change in people’s perceptions of dementia. In the past, it was thought of as a kind of fever and was not taken very seriously. People misunderstood it generally and adopted fatalistic attitudes towards dementia. Many thought that the patient of dementia can be given no treatment for cure. In the early phases of dementia, loss of memory was considered to be a regular effect of the aging of the patient and was thus ignored. Nowadays, people consider dementia as the mental health services’ cutting edge which encourages the changing care cultures with an emphasis upon the individuality and strength of people rather than their deficiencies. The model of care for dementia has undergone a transition from its medical to the social dimension. Clinicians and therapists tend to know the personality and life histories of the patients of dementia so that their well-being can be ensured. A new philosophy of treatment of the patients of dementia has surfaced over the years, which originates in social psychology. This is essentially a person-centered culture in which the nurses tend to incorporate the philosophical principles into creative professional practices. This has led to the development of an evidence base in terms of the myriad of qualitative research studies. Knowledge and awareness of the lived dementia experience have caused the nurses to endorse and apply the principles of participation, empowerment, and inclusion in the nursing practice. These principles have influenced the processes of assessment of dementia, sharing of its diagnosis, and the treatment given to the patients after its diagnosis. Over the years, nurses have acquired the skills required in all of these areas. This has brought a transition from the old degenerative model of the disease to the concept of positivity. Nowadays, people think of dementia as a disability which can be adapted to instead of an illness, which may lead the patient to death. There are several causes of dementia, though 75 percent of the cases of dementia pertain to vascular dementia together with the Alzheimer’s type of dementia. Pick’s disease is a common cause of dementia.
