A disorder characterized by mild deficits in one or more cognitive domains – such as memory, attention, or executive function – representing a decline from a previous level of functioning, but not severe enough to interfere significantly with independent daily activities.

Symptoms

Mild memory and learning impairment (also: Mild memory impairment, forgetting recent events, difficulty learning new information, subtle memory deficits, reduced learning capacity)
Cognitive function deficits (also: Cognitive deficits, reduced cognitive performance, decline in intellectual abilities, impaired problem solving, cognitive slowing)
Reduced attention and concentration (also: Reduced attention and concentration, difficulty concentrating, impaired sustained attention, poor concentration, shortened attention span)
Executive function deficits (also: Executive function deficits, poor planning, difficulty organising tasks, impaired decision making, reduced cognitive flexibility)
Subjective cognitive fatigue during mental tasks (also: Subjective cognitive fatigue, mental tiredness, difficulty thinking when tired, reduced cognitive stamina, brain fog)
Subjective difficulty learning despite objective performance (also: Subjective learning difficulty, perceiving cognitive decline not reflected in testing, self-reported memory problems, subjective cognitive complaint)
Severity insufficient for dementia (independence preserved) (also: Not meeting dementia criteria, preserved independence in daily activities, mild – not dementia, subtle cognitive decline, daily functioning intact)
