The term 'dementia' is used to describe the symptoms that occur when the brain is affected by certain diseases and conditions, such as memory loss.

What is important to understand is that there are various different types of dementia. Usually, people associate the term 'dementia' with Alzheimer's disease. Whilst this is the most
Alzheimer's disease

Alzheimer's disease affects around 465,000 people in the UK. [Figures from the Alzheimer's Society]. It is a physical disease that affects the brain. The disease sees 'plaques' and 'tangles' develop in the structure of the brain. These plaques and tangles kill off brain cells. People suffering with the disease are also affected by a shortage of important chemicals in their brains. These chemicals help to transmit messages around the brain. Without them, these messages cannot be delivered.

Alzheimer's is a progressive disease that damages more and more parts of the brain as time goes on. As this happens, so the symptoms become more severe. For example, people in the early stages of Alzheimer's experience short memory lapses, perhaps struggling to find the right words for things. As the disease develops, sufferers will forget words - along with the names of people and places - as a matter of course. Understandably, this is both frustrating and frightening, and accordingly Alzheimer's sufferers may experience mood swings as the disease takes
It is caused by problems in the supply of blood to the brain as a result of damage to a network of blood vessels in the organ called the vascular system. A damaged vascular system will not allow blood to reach the brain, which kills off brain cells - and this can lead to vascular dementia.

A number of conditions can incur damage to the vascular system including high blood pressure, heart problems, high cholesterol and diabetes. If these conditions are spotted early enough, they can be managed and as a result present less of a threat to the vascular system. Vascular dementia can also be brought on by a stroke.

Symptoms include forgetfulness, restlessness, confusion and aggression.

Dementia care

Individuals who are living with dementia need support. Family and friends have an important role to play, and as the condition advances the patient will often need some form of professional care. A live in carer who is trained in dementia care can provide both practical assistance and the emotional support and care that is needed when living with dementia. A live in carer also enables the person living with dementia to remain at home, which is greatly advantageous from the point of view of providing continuity of care in familiar surroundings promoting a sense of calm and overall
