Introduction to Non-Cognitive Symptoms of Dementia (NCSD)

Last updated on 21/11/2022

Non-cognitive symptoms of dementia are often an expression of unmet needs in a person with dementia.

  1. Behavioural symptoms include agitation, restlessness, aggression, disinhibition, pacing, shouting, and hoarding.
  2. Psychological symptoms include anxiety, apathy, sleep disturbances, depression, delusions, and hallucinations.


Non-Cognitive Symptoms of Dementia (NCSD) are also known as Behavioural and Psychological Symptoms of Dementia (BPSD). This term refers to a wide range of emotional, behavioural, and psychological symptoms that often accompany cognitive decline. These may include:

  1. Delusions and hallucinations
  2. Agitation, irritability, and aggression
  3. Sleep disturbances
  4. Repetitive behaviours and vocalisations
  5. Changes in appetite and eating habits
  6. Restlessness and anxiety
  7. Depression and apathy

The type and severity of symptoms can vary depending on the stage and type of dementia, and they can have a profound impact on quality of life – both for the individual and their caregivers.


Management Strategies

Addressing NCSD often requires a multifaceted approach, including:

  1. Non-pharmacological interventions – such as personalised activities, sensory stimulation, and structured routines
  2. Environmental modifications – creating a calm, dementia-friendly space
  3. Caregiver support and education – helping carers manage symptoms effectively
  4. Medication – when appropriate and following a thorough medical assessment
