UNIT 4222-365 UNDERSTAND THE PROCESS AND EXPERIENCE OF DEMENTIA
OUTCOME 1
1.1 The brain is a very complex organ and is divided up into different areas that control bodily functions. In dementia, some of the cells stop working. The part of the brain this occurs in will affect how that person thinks, remembers and communicates.
Alzheimer’s disease; is a physical disease affecting the brain. During the course of the disease, protein develops in the structure of the brain leading to the death of brain cells. People with Alzheimer’s also have a shortage of some chemicals in their brain. Alzheimer’s is a progressive disease which means that over time more parts of the brain are damaged. As this happens the symptoms become more severe. Alzheimer’s disease accounts for 60% to 80% of cases.
Vascular dementia; this is the second most common form of dementia after Alzheimer’s. It is caused by problems in the supply of blood to the brain, which usually occurs after a stroke. Vascular dementia also occurs because of brain injury or a blood vessel blockage to the brain.
Parkinson’s disease; the brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement. As the brain changes, the disease will begin to affect mental functions, including memory and the ability to pay attention, make sound judgements and plan steps needed to complete a task. Parkinson’s disease is a fairly common neurological disorder in older adults, estimated to affect nearly 2% of those over 65.
Huntington’s disease; this disease is a progressive brain disorder caused by a single defective gene on chromosome 4. Symptoms of the disease include abnormal involuntary movements, a severe decline in thinking and reasoning skills, irritability, depression and mood changes. The gene defect causes abnormalities in the brain protein that leads to worsening symptoms over time.
Wernicke-korsakoff syndrome; this syndrome is caused by severe deficiency thiamine vitamin B1. The...
