Dementia is a term used loosely, however, its definition is that of a collection of similar symptoms caused by different disease processes. Memory problems, loss of cognition and difficulty carrying out everyday tasks are signs of dementia, as are personality changes. Dementia is commonly caused by Alzheimer’s disease, a disease process whereby protein is deposited in the brain, causing disruption to neural signals. Cerebrovascular disease is another cause where parts of the brain are starved of oxygen and nutrients due to poor blood flow, resulting in death of the neural tissue, or “micro strokes”. Parkinson’s disease, head injuries, and chronic alcohol abuse are other less common causes of dementia. Dementia can be diagnosed with family descriptions of change in the persons behaviour, blood tests to rule out organic causes, an analytical mental questionnaire and a head CT scan. Medication can be used to effectively reduce a persons’ symptoms in some cases.
