Dementia is an umbrella term used to describe a range of progressive conditions that affect the brain.

In health and social care, it is essential for professionals to understand the various types of dementia as each has different characteristics, symptoms, and care requirements.

Here are the main types of dementia:

Alzheimer’s Disease

Description:
Alzheimer’s disease is the most common form of dementia, accounting for approximately 60-70% of all cases. It is characterised by the buildup of amyloid plaques and tau tangles in the brain, which disrupt neural connectivity and function.

Symptoms:

  • Memory loss, particularly recent events
  • Difficulty with language, such as finding the right words
  • Disorientation in time and place
  • Poor or decreased judgment
  • Changes in mood and behaviour

Vascular Dementia

Description:
Vascular dementia is the second most common type and is caused by reduced blood flow to the brain. This can result from a stroke or other conditions that damage blood vessels.

Symptoms:

  • Confusion and trouble concentrating
  • Changes in mood, such as apathy or depression
  • Difficulty planning and organising
  • Trouble with motor skills
  • Episodes of sudden disorientation

Lewy Body Dementia (LBD)

Description:
Lewy Body Dementia is characterised by the presence of Lewy bodies—abnormal protein deposits that affect chemicals in the brain, disrupting memory and motor control.

Symptoms:

  • Fluctuations in attention and alertness
  • Visual hallucinations
  • Movement disorders similar to Parkinson’s disease (e.g., tremors, stiffness)
  • Sleep disturbances
  • Difficulty with spatial awareness

Frontotemporal Dementia (FTD)

Description:
Frontotemporal Dementia affects the front and sides of the brain (the frontal and temporal lobes), which are responsible for personality, behaviour, and language.

Symptoms:

  • Changes in personality and behaviour, such as increased impulsivity
  • Difficulty with speech and language, including naming objects and understanding words
  • Movement issues similar to those seen in motor neurone disease
  • Emotional indifference or inappropriate social behaviour

Mixed Dementia

Description:
Mixed dementia involves a combination of two or more types of dementia, usually Alzheimer’s disease and vascular dementia.

Symptoms:

  • Symptoms vary depending on the mix of dementias but generally include memory impairment, confusion, and difficulty with thinking and understanding.

Parkinson’s Disease Dementia

Description:
This type of dementia occurs in some individuals with Parkinson’s disease, typically a year or more after the movement symptoms have been diagnosed.

Symptoms:

  • Memory and executive function issues
  • Visual hallucinations
  • Problem-solving difficulties
  • Increased difficulty with motor tasks

Creutzfeldt-Jakob Disease (CJD)

Description:
CJD is a rare and fatal condition caused by prions, small infectious pathogens. This leads to a rapid progression of dementia symptoms.

Symptoms:

  • Rapid decline in cognitive function
  • Changes in gait and coordination
  • Visual and auditory hallucinations
  • Muscle stiffness and twitching
  • Profound mental deterioration

Wernicke-Korsakoff Syndrome

Description:
Often associated with severe alcohol misuse, Wernicke-Korsakoff Syndrome results from a deficiency in thiamine (vitamin B1).

Symptoms:

  • Severe memory problems, especially with short-term memory
  • Confabulation (creating stories to fill in memory gaps)
  • Coordination issues
  • Nystagmus (rapid, uncontrolled eye movements)

Care Considerations:
Knowing the type of dementia is crucial for creating tailored care plans, including medical treatments, activity programmes, and support for daily living. Understanding these types also helps caregivers and healthcare providers offer more specific advice and support to individuals and their families.

In health and social care settings, person-centred care that respects and values the individual’s history, preferences, and needs is essential for all types of dementia.

Early diagnosis and intervention can significantly improve the quality of life for those affected.
