What lifestyle changes can help with cognitive impairment?

Aerobic exercise has the strongest modifiable evidence for cognitive health. Mediterranean diet reduces dementia risk. Sleep quality is critical for cognitive clearance (glymphatic system). Social engagement is protective. Address reversible causes: thyroid, B12, sleep apnoea, depression.

What integrative approaches support cognitive impairment?

Cognitive impairment spans a broad spectrum. B12 deficiency and hypothyroidism are reversible causes with strong treatment evidence. Aerobic exercise reduces cognitive decline risk. Sleep deprivation impairs cognitive function significantly and acutely. Depression can mimic dementia. Post-COVID cognitive impairment is an emerging area.

When should I seek professional support for cognitive impairment?

Progressive cognitive decline over months (dementia assessment required) Acute sudden cognitive change (possible delirium or stroke) Cognitive impairment affecting ability to work or manage daily life Significant personality or behavioural change alongside cognitive decline

Cognitive Impairment

Q: What is cognitive impairment?

Cognitive impairment encompasses any reduction from an individual's previous cognitive baseline across one or more domains: memory, attention, processing speed, language, executive function, or visuospatial ability. It ranges from mild cognitive impairment (MCI) — a subtle decline not meeting criteria for dementia — to more significant acquired impairment from illness, injury, or medication. Causes include neurodegenerative disease, vascular disease (small vessel disease, stroke), traumatic brain injury, severe depression (pseudodementia), thyroid dysfunction, vitamin B12 deficiency, chronic medication effects, prolonged sleep deprivation, and post-viral syndromes.

A broad reduction in cognitive functions including memory, attention, executive function, processing speed, or language. May be acute (reversible) or progressive (neurodegenerative), with wide-ranging causes.

Quick answer

Cognitive impairment (ICD-10: R41.3; ICD-11: MB21.7) spans reversible causes (B12, thyroid, depression) to neurodegenerative conditions. Aerobic exercise, sleep quality, and Mediterranean diet have the strongest evidence for cognitive health. Acute or rapidly progressive impairment requires urgent assessment.
