Receiving a dementia diagnosis — whether for yourself or a loved one — can be overwhelming. Dementia is not a single disease but a collection of symptoms associated with a decline in memory, thinking and social abilities. This guide is designed to help families understand what dementia is, recognise early signs, and explore the care options available.

What is Dementia?

Dementia describes a range of progressive neurological conditions that affect memory, thinking, behaviour and the ability to perform everyday tasks. It is not a normal part of ageing, though it is more common as we get older. Dementia occurs when nerve cells in the brain stop working properly and eventually die, leading to a gradual decline in cognitive and physical abilities.

The term "dementia" covers several different conditions, each with distinct characteristics and progression. What all forms of dementia share is a progressive impact on memory, language, judgment and behaviour — though the rate of progression and specific symptoms vary significantly from person to person.

Common Types of Dementia

Alzheimer's Disease

Alzheimer's is the most common form of dementia, accounting for 50–80% of all cases. It is characterised by the build-up of abnormal proteins in the brain, leading to the death of brain cells. Symptoms typically include memory loss, confusion about time and place, difficulty with language, and changes in mood and behaviour.

Vascular Dementia

Vascular dementia results from reduced blood flow to the brain, often following a stroke or from damaged blood vessels. It is the second most common form of dementia. Symptoms may include difficulty with planning, slower thinking, and mood changes.

Lewy Body Dementia

Lewy body dementia is caused by abnormal protein deposits (Lewy bodies) in the brain. It often features visual hallucinations, movement problems similar to Parkinson's disease, fluctuating awareness, and sleep disturbances.

Frontotemporal Dementia

Frontotemporal dementia affects the front and side parts of the brain, causing changes in personality, behaviour and language. It often appears in younger people (under 65).

Early Signs to Look For

Dementia develops gradually, and early signs can be subtle. Being aware of these can help you recognise when to seek professional advice:

  • Memory loss — forgetting recently learned information or repeating the same questions
  • Difficulty with familiar tasks — struggling with cooking, shopping, or managing finances
  • Language problems — trouble finding the right word or following conversations
  • Disorientation — losing track of dates, seasons, or becoming confused in familiar places
  • Mood or behaviour changes — uncharacteristic irritability, anxiety or depression
  • Loss of initiative — withdrawing from activities, hobbies or social contact

Important: Occasional forgetfulness is normal. Dementia is characterised by persistent, progressive memory loss that interferes with daily functioning. If you are concerned, contact your GP for an assessment.

When to Consider Professional Care

As dementia progresses, the level of care required increases. Consider professional care when your loved one requires 24-hour supervision for safety, complex nursing care is needed, behavioural changes are challenging to manage at home, or family carers are experiencing burnout.
