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. Expand
Mild cognitive impairment as a diagnostic entity

  • 1 September 2004
TLDR
It is suggested that the diagnosis of mild cognitive impairment can be made in a fashion similar to the clinical diagnoses of dementia and AD, and an algorithm is presented to assist the clinician in identifying subjects and subclassifying them into the various types of MCI. Expand
The Diagnosis of Mild Cognitive Impairment due to Alzheimer’s Disease: Recommendations from the National Institute on Aging-Alzheimer’s Association Workgroups on Diagnostic Guidelines for Alzheimer’s…
TLDR
Criteria for the symptomatic predementia phase of Alzheimer’s disease (AD), referred to in this article as mild cognitive impairment due to AD, has four levels of certainty, depending on the presence and nature of the biomarker findings. Expand
Expanded GGGGCC Hexanucleotide Repeat in Noncoding Region of C9ORF72 Causes Chromosome 9p-Linked FTD and ALS
TLDR
It is found that repeat expansion in C9ORF72 is a major cause of both FTD and ALS, suggesting multiple disease mechanisms. Expand
Current concepts in mild cognitive impairment.
TLDR
A group of experts on aging and MCI from around the world in the fields of neurology, psychiatry, geriatrics, neuropsychology, neuroimaging, neuropathology, clinical trials, and ethics was convened to summarize the current state of the field of MCI. Expand
Mild cognitive impairment – beyond controversies, towards a consensus: report of the International Working Group on Mild Cognitive Impairment
TLDR
A multidisciplinary, international group of experts discussed the current status and future directions of MCI, with regard to clinical presentation, cognitive and functional assessment, and the role of neuroimaging, biomarkers and genetics. Expand
The Alzheimer's disease neuroimaging initiative.
TLDR
The Alzheimer's Disease Neuroimaging Initiative will help identify clinical, neuroimaging, and biomarker outcome measures that provide the highest power for measurement of longitudinal changes and for prediction of transitions. Expand
Hypothetical model of dynamic biomarkers of the Alzheimer's pathological cascade
TLDR
This work proposes a model that relates disease stage to AD biomarkers in which Abeta biomarkers become abnormal first, before neurodegenerative biomarkers and cognitive symptoms, and neurodegnerative biomarker become abnormal later, and correlate with clinical symptom severity. Expand
Diagnostic criteria for mild cognitive impairment in Parkinson's disease: Movement Disorder Society Task Force guidelines
TLDR
These diagnostic criteria will support future research efforts to identify at the earliest stage those PD patients at increased risk of progressive cognitive decline and dementia who may benefit from clinical interventions at a predementia stage. Expand
Mild cognitive impairment
TLDR
Mild cognitive impairment can be regarded as a risk state for dementia, and its identification could lead to secondary prevention by controlling risk factors such as systolic hypertension. Expand
