Dementia and Delirium team

What is Dementia?

Dementia is a broad term that describes a set of symptoms including memory loss, challenges with thinking, processing, problem solving and language. Many different diseases and events lead to the development of these symptoms.

“Research shows there are more than 850,000 people in the UK who have dementia. One in 14 people over the age of 65 have dementia, and the condition affects 1 in 6 people over 80.

“The number of people with dementia is increasing because people are living longer. It is estimated that by 2025, the number of people with dementia in the UK will be more than 1 million.” (

Types of dementia

Alzheimer’s disease

This is the most common type of dementia.

Alzheimer’s disease is a physical condition which affects the brain. Protein builds up between nerve cells and develops into plaques and tangles. These plaques and tangles interrupt, and eventually stop, the cells from communicating with each other resulting in cell death. This cell death leads to loss of brain tissue.

Vascular dementia

Vascular dementia develops when there is an interruption to the blood supply in the brain. This occurs, for example, if someone has a stroke, TIA or a head injury that results in hypoxia.

Mixed dementia

Mixed dementia is diagnosed when someone has more than one disease process which is contributing to their presentation. People most frequently have a combination of Alzheimer’s disease and vascular dementia although other combinations also exist.

Rarer types

There are over 100 different types of dementia. Some of the rarer types include Creutzfeldt-Jakob disease (CJD), Normal pressure hydrocephalus and progressive supranuclear palsy (PSP).

Please see the Alzheimer’s society website for details of these conditions:

Signs and symptoms of dementia

Regardless of which type of dementia is diagnosed and what part of the brain is affected, each person will experience dementia in their own unique way.

  • Memory problems
  • Cognitive ability e.g. processing information
  • Communication
  • Changes in personality and behaviour
  • Emotional and language dysfunction
  • Spatial disorientation
  • Functional disability.


Delirium is a common medical problem that is characterised by changes in mental function and occurs more often among older people.

When delirium occurs, people are confused and may be either very agitated or quiet and drowsy.

The onset of delirium is always sudden. It usually only lasts for a few days but may persists for weeks. It can be a serious condition.
