Alzheimer’s disease – is a physical disease that affects the brain. In individuals with Alzheimer’s disease a bad protein develops in the brain causing damage to the brain cells and their connections. The first sign of Alzheimer’s symptom is short term memory loss; the individual finds it difficult to remember recent events or conversations. This can lead to them repeating stories or asking the same question over and over again. There are many symptoms of Alzheimer disease: problem with speech and language, low mood or anxiety, problem moving around without assistance or personality changes, such as becoming aggressive.
– Vascular dementia – is caused by oxygen failing to get to the brain cells as a result of problems with the blood supply. In vascular dementia, changes in thinking skills sometimes occur suddenly following strokes that block major brain blood vessels. Symptoms include: problem with concentration, feeling confused and disorientated, slowness of thought and difficulty walking and keeping balance.
– Dementia with Lewy bodies (DLB) – they are tiny deposits of a protein that appear in nerve cells in the brain. There are two main factors that allow us to recognise these disease: low levels of important chemicals that bring messages between nerve cells and a loss of connections between nerve cells, which then die. People with dementia with Lewy bodies may have: slow movements, hallucinations and sleep disturbance.
