On Day 18 of World Alzheimer’s Awareness Month 2015 #WAM2015, or as I prefer to call it World Dementia Month or Dementia Awareness Month 2015, #DAM2015, I had the pleasure of listening to a geriatrician Dr Jane Tolman present at the Better Practice conference in Launceston: Dementia: how did we get it so wrong?.
Some of her thoughts for this presentation have come from participating in the second running of the Massive Open Online Course (MOOC) on Understanding Dementia run by the Wicking Dementia Research and Education Centre at the University of Tasmania, which provided a forum for learning and discussion about dementia for 15,000 carers, health professionals and interested persons from all around the world.
I think there is much room for improvement in the way health professionals have dealt with dementia.
We handle the diagnosis of dementia very badly. Families complain that doctors are unwilling to make the diagnosis, defer the diagnosis, or deny the diagnosis (just getting old). Statistics tell us that only about 40% of people with dementia ever get a diagnosis. There are established sets of criteria for diagnosis; but many of us still use a cut-off score on a basic cognitive test to make a diagnosis, maintain that a diagnosis can only be made post mortem with a biopsy, or tell our patients that it is a diagnosis “of exclusion”. While evidence suggests that the personal story (history in doctors’ language) offers considerably more weight to a diagnosis than any examination finding or test, families still find it hard to put their case, present their information and are sometimes dismissed due to privacy issues.
Notoriously, people with dementia develop a lack of understanding of their situation. Doctors call this “lack of insight”. People with dementia also lack skills required to make good decisions, to reason and to solve problems. These features of dementia are poorly recognised by many health professionals. And yet they can expose the person with dementia to extreme danger. Assessing cognitive capacity for decision-making can be challenging. Many clinicians are hesitant about providing an assessment, and many who do so, provide an inadequate assessment. It is essential that doctors embrace this role, and develop their competence in such assessments.
What families most want to know about dementia is what will happen as the condition progresses. When we do make a diagnosis, we rarely address this. Current staging systems of dementia tend to focus on what people can do rather than what their needs are, are often designed for research, and rarely address the real need: how to provide dignity to very vulnerable people. At the time of diagnosis, or soon after, loved ones (and the person with dementia where relevant) should be given information about the stages ahead and what they mean. There should be a “road map” to help people navigate the path.
Dementia is often described as a memory problem and clinics for its diagnosis and management are still sometimes labelled as Memory Clinics. It’s time that we acknowledged that dementia is about a range of domains, including Cognitive (memory, language, insight, judgement, planning, reasoning), Function (inability to perform household and other tasks and ultimately personal care) , Psychiatric (commonly delusions, hallucinations and depression), Behavioural (aggression, screaming, following, calling out) and Physical (swallowing, continence, mobility and eating). Families and carers have the right to know the facts. When these symptoms of dementia arise, families should not be surprised and need to be able to recognise these as manifestations of the disease.
Dementia is a relentlessly progressive terminal illness. As a profession we have failed to identify dementia as a disease which has much more in common with cancer than with forgetfulness.
At the time of diagnosis of other neurodegenerative conditions such as Motor Neuron Disease, a palliative approach is often instituted from the start, and early decisions are made about future feeding and assisted breathing. But in the case of dementia, we often offer families few choices, because we have failed to recognise that quality of life will be compromised, or to identify the role quality of life plays in decisions about management.
