What is dementia?

Dementia is an ‘umbrella’ term for a range of illnesses which cause a progressive decline in a person’s functioning.

It affects thinking, behaviour and the ability to perform tasks.

A dementia diagnosis affects everyone; from the individual diagnosed, to their family and friends. But, it can particularly take a toll on a spouse, making it difficult to strengthen a relationship already going through so much change.

Because dementia and memory loss affects each individual differently, it’s impossible to make assumptions or generalities. From the beginning to end, a couple’s journey in dealing with dementia is completely unique to them and constantly changing. Every couple will navigate their illness and the evolution of their relationship in their own way.

What's the difference between dementia and alzheimer's disease?

Many people often confuse the terms Alzheimer’s disease and dementia. Although they are both used interchangeably, there are distinct differences between them. 


Dementia is not a disease, but a group of symptoms that are associated with a decline in thinking, reasoning and/or remembering. If someone has dementia, they may have difficulty carrying out daily tasks they have performed routinely and independently throughout their lives. 

The two most common types of dementia are:

                 o Alzheimer’s disease

                 o Vascular dementia, which is the hardening of the

                    arteries in the brain that causes blockage in blood


These two conditions account for the vast majority of dementia cases. Both conditions are irreversible, although sometimes their symptoms can be managed. 


Alzheimer’s disease is the most common form of dementia, and this progressive brain disorder has no known cause or cure. This disease leads to memory loss, confusion, impaired judgement, personality changes, disorientation and the inability to communicate. Dementia occurs in the mid to later stages of Alzheimer’s disease.

Doctors can accurately diagnose the dementia symptoms in 90% of cases.
