Depression looks like dementia?

Depressive pseudodementia is cognitive impairment on the background of a depressive illness, sometimes in the absence of typical symptoms of depression.

In this case, it’s not uncommon for someone with dementia realizing what is happening to them during moments of clarity, which can lead to depression. This is why the cognitive, mental, and emotional challenges of aging adults need to be handled with patience, empathy, and loving care.

Depression or Dementia ?

Depression looks like dementia

Here are some of the signs to watch out for:

Simulated dementia is cognitive impairment that has been feigned deliberately in the pursuit of some form of gain.

The term pseudodementia has been used historically to describe the reversible cognitive impairment that may accompany depression, but it has lacked precise and consistent definition. The neuropsychological profile of older depressed patients varies according to the age at which depression first occurs, suggesting the involvement of different biological mechanisms ( Herrmann et al 2007 ). Late-onset depression is accompanied by impairment of executive functioning and processing speed and is associated with frontal and temporal white matter hyperintensities on MRI ( O’Brien et al 2006 ), with deep rather than periventricular lesions being most implicated. By contrast, in those with early-onset depression episodic and semantic memory is more typically affected, and neuroimaging reveals evidence of hippocampal atrophy ( McKinnon et al 2009 ). It is thought that hippocampal damage is mediated via neurophysiological stress – possibly cortisol hypersecretion – but there is no apparent correlation with raised cortisol levels. Recent studies refute the claim that the neurocognitive changes associated with late-life depression are temporary and remit after recovery. Bhalla et al (2006) found that 94% of those with depression who were cognitively impaired at baseline remained so a year later, despite being no longer depressed. Moreover, this study and others suggest that depressive symptoms without apparent cognitive impairment predict the later development of cognitive decline and dementia, especially in those with persistent and more severe depressive symptoms.

The difficulties people with dementia may have with their mental abilities can make it harder to treat depression. This could include difficulties with their attention, communication, memory or reasoning. To have the most benefit, some types of talking therapy need a person to have these mental abilities intact. This includes cognitive behavioural therapy (CBT).

Most people feel low or sad from time to time. This is not the same as being depressed. Depression is a condition that can last for several weeks or months. When a person has depression a number of negative feelings can dominate their life, including sadness, hopelessness and a loss of interest in things they used to enjoy.

A third condition that is sometimes confused with depression or dementia is delirium. Delirium is a short-term memory loss that results from a person being put into new, unfamiliar surroundings or living conditions, becoming dehydrated, or having a reaction to medication. This condition is often reversible if treated early, whereas most types of depression and dementia can be treated but aren’t reversible.

Dementia is the umbrella term for many different conditions that deal with reduced brain function. The most common of these conditions is Alzheimer’s disease, which accounts for 60 – 80% of dementia diagnoses.
