The literature on cognitive markers in preclinical AD is reviewed. The findings demonstrate that impairment in multiple cognitive domains is typically observed several years before clinical diagnosis. Measures of executive functioning, episodic memory and perceptual speed appear to be most effective at identifying at‐risk individuals. The fact that these cognitive domains are most implicated in normal cognitive aging suggests that the cognitive deficit observed preclinically is not…

TLDR
This overview focuses on the cognitive transition between normal aging and dementia, and suggests that multiple indicators of cognitive functioning should be included along with markers from other domains that have been linked to subsequent dementia (such as brain imaging, genetics, and lifestyle variables).
Neuropsychological assessment of dementia.
TLDR
Discrete patterns of cognitive deficits occur in AD and several neuropathologically distinct age-associated neurodegenerative disorders and knowledge of these differences helps to clinically distinguish among various causes of dementia and provides useful models for understanding brain-behavior relationships that mediate cognitive abilities affected in various neurodegenersative diseases.

TLDR
The pattern and progression of these neuropsychological changes fit well with the proposed distribution and spread of AD pathology and serve as important cognitive markers of early disease.
Cognitive Profiles in Alzheimer’s Disease and in Mild Cognitive Impairment of Different Etiologies
TLDR
Analysis of cognitive profiles of nondemented patients with MCI diagnosed with prodromal Alzheimer’s disease and those diagnosed with vascular disease found that both groups could be distinguished from dementia patients with regards to performance on measures of memory but not on non-memory measures.
Cognition in Preclinical Dementia: Current Knowledge and Future Prospects
TLDR
The cognitive transition from normal aging to dementia -- a period often referred to as the preclinical phase of dementia -- is discussed, with marked preclinical cognitive deficits several years before diagnosis in both Alzheimer´s disease and vascular dementia.
Memory impairment, executive dysfunction, and intellectual decline in preclinical Alzheimer's disease
TLDR
To examine the preclinical onset of cognitive decline, subjects were aligned at the time of initial AD diagnosis and the cognitive course preceding diagnosis found that declines in performance on tests of episodic memory accelerated 7 years before diagnosis.
Progressive impairment on neuropsychological tasks in a longitudinal study of preclinical Alzheimer's disease.
TLDR
A detailed neuropsychological evaluation of 11 patients with Alzheimer's disease over the course of 3 years up to and including the 1st year of nonnormal diagnosis suggests that performance falls off rapidly in all areas of cognitive functioning.

Stability of the preclinical episodic memory deficit in Alzheimer's disease.
TLDR
The results indicate that Alzheimer's disease is characterized by a long preclinical period during which episodic memory deficits are detectable, and the magnitude of these deficits appears to be quite stable, at least up to 3 years before diagnosis.
Mild cognitive impairments predict dementia in nondemented elderly patients with memory loss.
TLDR
Among nondemented elderly patients, memory loss alone rarely progresses to dementia in the subsequent 2 years, however, the risk of dementia is significantly increased among patients with clear cognitive impairments beyond memory loss.
Association between memory complaints and incident Alzheimer's disease in elderly people with normal baseline cognition.
TLDR
The findings of this study suggest that memory complaints are a relatively strong predictor of incident Alzheimer's disease in older persons in whom cognitive impairment is not yet apparent, and suggest that older persons may be aware of a decline in cognition at a time when mental status tests are still unable to detect a decline from premorbid functioning.
Rate of cognitive decline in preclinical Alzheimer's disease: the role of comorbidity.
TLDR
The results suggest that many variables affecting the onset of the degenerative process as well as cognitive functioning in normal aging exert little influence on rate of cognitive change in preclinical AD, reflecting the fact that the emerging dementia disease overshadows the role of these variables for cognitive functioning.
Neuropsychological detection and characterization of preclinical Alzheimer's disease
TLDR
Results lend support to the notion of a preclinical phase of AD and indicate that this very early stage of AD is characterized by poor word-finding ability, abstract reasoning, and memory.
Cognitive process in preclinical phase of dementia.
TLDR
The results seem to show that preclinical deficits in dementia and Alzheimer's disease reflect the deterioration of a general cognitive factor, which may be interpreted as the disturbance of central, control processes.
Influences of cognitive support on episodic remembering: tracing the process of loss from normal aging to Alzheimer's disease.
TLDR
A general impairment of episodic memory may precede reductions in cognitive reserve capacity in the early development of AD, and this pattern was also seen in the prevalent AD patients at both times of measurement.
Diagnosis of Preclinical Alzheimer's Disease in a Clinical Setting
TLDR
Investigating whether the preclinical stage of Alzheimer's disease (AD) can be diagnosed in a clinical setting found that subjects with preclinical AD can be distinguished from subjects with nonprogressive mild cognitive impairment and from Subjects with very mild AD-type dementia.
Cognitive predictors of incident Alzheimer's disease: a prospective longitudinal study.
TLDR
Recall of organizable words, recognition of faces, and letter fluency were reliable predictors of subsequent dementia status after differences in MMSE performance were partialed out, indicating that although the MMSE is useful in predicting dementia, there is an additional advantage of assessing specific indices of cognitive functioning.
Mild cognitive impairment: clinical characterization and outcome.
TLDR
Patients who meet the criteria for MCI can be differentiated from healthy control subjects and those with very mild AD, and appear to constitute a clinical entity that can be characterized for treatment interventions.
