Health Topics - Memory Loss and Dementia

Forgetfulness is a condition which tends to be associated with ageing and it is true that as we age our short term memory may lose its edge.  We may sometimes forget small things that happened yesterday.  However, our long term memory can become more vivid.  More serious is the development of conditions such as Alzheimer's Disease and Dementia

What is Dementia?
Dementia is a term that covers a number of diseases that occur as a result of physical changes in the structure of the brain. These changes are caused by specific conditions, and result in impairment of memory, thinking and skills, sometimes accompanied by altered emotional expression and sensory perception. Dementia is almost always progressive, which means the symptoms will gradually get worse.

Alzheimer's disease is the most common form of dementia, affecting approximately 20,000 to 28,500 New Zealanders. (There is currently an estimated 40,746 New Zealanders with some form of dementia). It is a progressive disease of the brain in which cells are damaged and may die without being replaced. It results in impaired memory, thinking and behaviour.

Symptoms include:

  • having increasing difficulty managing complex or new tasks
  • showing lack of initiative or withdrawal from usual activities
  • emotional and personality changes
  • having problems finding the right words or understanding what is being said to them

No one single factor has been identified as a cause for Alzheimer's disease, and it is likely that a combination of factors, including age, genetic inheritance and environmental factors are involved. It is common for people of all ages to experience forgetfulness. Forgetfulness is not being able to remember something at a specific time but the memory returns at some later time in most cases. This kind of forgetfulness is not cause for alarm.

Examples for normal forgetfulness:

  • Walking into the kitchen and forgetting what you went in for
  • Misplacing your keys
  • Forgetting the names of people
  • Not remembering a specific place or brand name ("Tip of the tongue" experience)

However, there is a cause for concern when memory loss starts to affect the daily life of a person.

Common signs of dementia:

  • Recent memory loss that affects job skills
  • Difficulty performing familiar tasks
  • Problems with language
  • Time and place disorientation
  • Problems keeping track of things
  • Repeatedly misplacing things and putting them in inappropriate places
  • Changes in mood
  • Personality changes
  • Loss of initiative

If you are worried about your memory you should see your GP. There are many treatable causes of memory loss. If the memory loss is caused by dementia an early diagnosis is critical for planning and treatment.

You can also contact organisations such as the Alzheimer's Society, ADARDS Society or your local community health or healthcare centre for assistance for the person affected, and also their family and friends.  It is a particularly tragic disease which may profoundly change the lives of those close to the person with Dementia.  Support for all concerned is available and can include practical help in the home, carer relief and daycare for social interaction for the person with Dementia.

Unfortunately many people are still unaware of Dementia and its far reaching effects - Alzheimer's NZ hopes to raise awareness and change society's views about the disease. The Alzheimers NZ site has very useful information on this topic and a list of links to other similar organisations.

The Alzheimers Auckland covers the Auckland, Waitakere, North Shore and Rodney areas.  They hold  informative sessions for carers of people with dementia.  If you would like to know more contact the Dementia Auckland.


Alzheimers New Zealand recently annonced the release of two new publications

Women and Dementia: a global research review
This important and timely report reveals the disproportionate impact dementia has on women  - most people living with dementia are women and women are more at risk of developing dementia than men; women are more likely to be the primary caregiver in a family situation involving dementia affecting their health, social relationships and financial security; and women are also most likely to be the provider of formal care in the community and in hospitals and care homes where low status, poor salary and inadequate training affects them, their family and people living with dementia.

The summary version of the report is available here.

New About Dementia booklet
Alzheimers NZ has released a new booklet titled About Dementia. This is the first in a comprehensive new series of booklets Alzheimers NZ is developing as part of a cross-agency project to develop a new, nationally consistent suite of resources for people affected by dementia. The groups working with Alzheimers NZ on this project are the Ministry of Health, representatives from the four DHB Regional Dementia work streams, and the New Zealand Dementia Cooperative.  You can access a downloadable pdf copy of About Dementia here


Improving the lives of people with dementia
This 2014 publication outlines nine key areas the Ministry of Health will support over the next three years to maximize the health, independence and wellbeing of people with dementia.

Good health is essential for the social and economic wellbeing of New Zealanders. As the population of older people grows, so too will the population of people with dementia. An ageing population means that maximising the health, independence and wellbeing of people with dementia is a key part of ensuring the good health of New Zealanders. For more information and to download a pdf copy visit the Ministry of Health website.


THE DISREMEMBERED - Where Does Identity Go Once Memory Falters? By Charles Leadbeater.
This article explores the nature of identity and looks at the issues faced by people living with dementia. Dementia undermines all of our philosophical assumptions about the coherence of the self and raises deeply troubling issues about our obligations to care for people whose identity might have changed in the most disturbing ways. In turn, those changes challenge us to confront our philosophical and ethical assumptions about what makes up that identity in the first place. Everyone touched by the disease goes through a crash-course in the philosophy of mind. Philosophy is not of much practical use with most illnesses but in the case of dementia it provides insights about selfhood and identity that can help us make sense of the condition and our own reactions to it.

The road to reducing dementia onset and prevalence: are diet and physical activity interventions worth investing in? “Policy-makers must be cognizant of the fact that no singular government intervention/policy, operating on its own, can have the effect of directly reducing dementia onset/prevalence and changing lifestyle habits. Six actions for policy-makers are identified in this issues brief which have the potential to have immeasurable benefits: i) development of a comprehensive dementia prevention strategy, ii) establishment of a body whose aim is to keep track of scientific research (central to this will be the establishment of a national digital dementia research repository), iii) ensuring a multisectoral approach is adopted in the fight against dementia that includes both ‘traditional’ and ‘incidental’ health agencies, iv) continued investment into research and innovation, v) identifying incentives beyond the health domainand vi) development of longevity literacy programs.” Source: Deeble Institute


Cognitive Aging: Progress in Understanding and Opportunities for Action 11 “Cognitive Aging assesses the public health dimensions of cognitive aging with an emphasis on definitions and terminology, epidemiology and surveillance, prevention and intervention, education of health professionals, and public awareness and education. This report makes specific recommendations for individuals to reduce the risks of cognitive decline with aging. Aging is inevitable, but there are actions that can be taken by individuals, families, communities, and society that may help to prevent or ameliorate the impact of aging on the brain, understand more about its impact, and help older adults live more fully and independent lives. Cognitive aging is not just an individual or a family or a health care system challenge. It is an issue that affects the fabric of society and requires actions by many and varied stakeholders.” Source: Institute of Medicine *sign up for free account to download

 Free online dementia awareness raising tool: Dementia Commitment
