Each seven seconds, somebody on this planet is recognized with dementia. A typical case that I typically see in my follow is as follows: A 76-year-old girl has a two-year historical past of progressive worsening of short-term reminiscence and cognitive decline. She will be able to’t recall the names of her grandchildren and is devastated by her deteriorating skills.

Nevertheless, this isn’t the primary time in her life that she has had emotions of loss and despair. Over the previous 30 years, she has intermittently struggled with despair and nervousness. Her household has many questions: Does she have dementia or Alzheimer’s? Might her despair have led to a dementia prognosis? Is it solely despair and never dementia? These are all good questions and the collective reply to them is “sure.”

Dementia and despair

Dementia and despair are the 2 dreaded “D” diagnoses which might be more and more robbing our getting old inhabitants of well being and happiness as each issues strategy close to epidemic proportions, exacerbated by the COVID-19 pandemic. The truth is, the prevalence of despair in folks with dementia has been reported to exceed 60 per cent.

Regardless of their apparent variations, it’s turning into ever extra obvious that despair and dementia could also be two sides of the identical coin. Folks with dementia typically have despair; if the despair stays untreated, the related reminiscence and cognitive issues worsen. Conversely, a major historical past of despair appears to be a threat issue for dementia; the 2 issues could thus co-exist in a vicious self-sustaining cycle.

Within the age of COVID-19, these connections change into much more stark — and spotlight an much more dire situation. If loneliness and isolation are already famous threat elements for each despair and dementia, then the lockdowns stopping household and caregivers from interacting with their family members in long-term care served to hasten the decline. We’re solely simply starting to watch the grim penalties of this imposed isolation — a essential step, taken with the objective of saving lives, however which, in the long run, could trigger much more destruction/despair within the lives of these dwelling with dementia and Alzheimer’s.

Complicated connection

Clearly, the connection between dementia and despair is deep, multi-faceted and a rising space of scientific and public well being curiosity.

Folks with a historical past of despair typically develop dementia.

Greater than half of sufferers with dementia additionally undergo from despair. Within the early phases of dementia, the particular person realizes that they don’t seem to be the identical particular person they as soon as had been — cognition is slowed, reminiscence will not be as sharp, phrases don’t queue up within the mind as quick as they used to. This serves to additional compromise cognitive reserve and to permit the signs of dementia to be manifested earlier and with better severity. To additional complicate the connection, many individuals with dementia could not be capable of acknowledge that they’re, actually, depressed.

As nicely, it seems that folks with a previous historical past of despair have double the danger of creating dementia. That is true even when the despair occurred greater than a decade earlier than the onset of dementia.

There are clear mechanisms for this elevated threat. Extended harm to part of the mind known as the hippocampus, a discovering linked to despair, has been proposed to underlie this causative relationship. That is additional confirmed by research that display elevated hippocampal deposits of plaques and tangles in folks with Alzheimer’s (the pathological hallmarks of the illness) with lifetime histories of despair. As well as, different researchers speculate that mind irritation that always happens when an individual is depressed could also be a long-term triggering issue for dementia. These explanations additional display the societal want to acknowledge and deal with despair.

Development of a single illness?

In some folks, despair and dementia usually are not cause-and-effect, however could also be merely totally different phases of the identical single-disease course of.

In some folks, despair and dementia is probably not trigger and impact, however two phases of the identical single-disease course of.

Despair will not be solely a threat issue for dementia, it might even be the beginning of the dementia. Despair will be the early manifestation of an underlying neurodegenerative illness.

For such folks, the remedy of despair can be of explicit significance. Nevertheless, in different folks, the remedy for despair could paradoxically worsen the signs of dementia. Cognitive impairment in depressed aged will be exacerbated by means of antidepressants, although with using fashionable SSRI-type antidepressants, this could change into much less probably.

Overlapping signs

Lastly, the signs of dementia and despair can mimic one another, which implies folks with dementia could also be mistakenly recognized with despair and vice versa. Early dementia signs embody reminiscence issues (significantly remembering latest occasions), growing confusion, behaviour adjustments, apathy, social withdrawal and incapability to do on a regular basis duties.

Many of those signs are shared with despair, during which sufferers expertise sleep disturbances, lack of power (so even small duties take further effort), nervousness, restlessness and issues with pondering, concentrating, making choices and remembering issues.

Alzheimer’s illness impacts an entire household, not simply the person.

Clearly, the connection between dementia and despair is complicated, with the 2 issues being simply confused with one another in addition to being threat elements for one another. Each are devastating, each are growing in prevalence in our getting old inhabitants and each could also be considerably affected by the stresses of COVID-19.

Nevertheless, there may be one main distinction separating the 2: there are not any efficient therapies for dementia, whereas there are a selection of doubtless efficient brokers for despair. Efforts ought to at all times be made to detect the presence of despair, and if current, to deal with it, thereby eliminating one of many faces of this two-faced dementia-depression coin.
