Question 1

What is cognitive decline?

Accepted Answer

Cognitive decline describes a worsening in one or more cognitive domains — memory, attention, language, executive function, visuospatial ability — beyond what is expected with normal ageing. Mild cognitive impairment (MCI) occupies the spectrum between normal ageing and dementia, with approximately a third of MCI cases progressing to dementia over time. Reversible causes of cognitive decline are important to identify: thyroid dysfunction, vitamin B12 deficiency, depression, sleep apnoea, and medication side effects can all produce significant cognitive impairment that improves with treatment.

Question 2

What do people commonly experience with cognitive decline?

Accepted Answer

Increasing difficulty remembering recent events or conversations
Struggling to find words or follow complex discussions
Slower thinking or difficulty planning and organising
Reduced ability to manage tasks that were previously straightforward
Awareness (often early) that cognitive function has changed

Question 3

What lifestyle changes can help with cognitive decline?

Accepted Answer

Aerobic exercise is the strongest lifestyle modifier for cognitive reserve and dementia risk. Mediterranean and MIND diets have evidence for cognitive protection. Sleep quality is essential for amyloid clearance from the brain. Social engagement maintains cognitive stimulation. Address modifiable cardiovascular risk factors (hypertension, diabetes, cholesterol).

Question 4

What integrative approaches support cognitive decline?

Accepted Answer

Dementia affects an estimated 55 million people globally. The Lancet Commission identifies 12 modifiable risk factors responsible for approximately 40% of dementias. Physical exercise has the strongest evidence for cognitive reserve maintenance. Mediterranean diet and good sleep have significant evidence. Cholinesterase inhibitors have evidence for Alzheimer's symptom management.

Question 5

When should I seek professional support for cognitive decline?

Accepted Answer

Noticeable cognitive decline that is progressive over months
A family member expressing concern about cognitive changes
Cognitive difficulties impairing safety (driving, medication management)
Sudden significant change in cognition (urgent assessment)
