Neurocognitive disorders—including delirium, mild cognitive impairment and dementia—are characterized by decline from a previously attained level of cognitive functioning. These disorders have diverse clinical characteristics and aetiologies, with Alzheimer disease, cerebrovascular disease, Lewy body disease, frontotemporal degeneration, traumatic brain injury, infections, and alcohol abuse representing common causes. This diversity is reflected by the variety of approaches to classifying these… 
Alzheimer’s disease and other neurocognitive disorders
Abstract Alzheimer’s disease (AD) and other neurocognitive disorders are one of the major classes of disorders relevant to older adults. In addition to cognitive symptoms, psychiatric complications
Mild Neurocognitive Disorder: An Old Wine in a New Bottle
TLDR
While the category “mild NCD” may improve reliability of diagnoses, it has yet to withstand scientific scrutiny to be considered a valid construct.
Peculiarities of Neurological Disorders and Study Designs.
TLDR
The basic aspects of the commonest neurological disorders are addressed along with the proposed structure of randomized clinical trials (RCTs) and the core elements of the study designs are outlined.
The reliability and validity of DSM 5 diagnostic criteria for neurocognitive disorder and relationship with plasma neurofilament light in a down syndrome population
TLDR
DSM-5 neurocognitive disorder criteria can be used reliably in a Down syndrome population and has higher concurrence with clinical judgement than the older DSM-IV and ICD-10 criteria.
Evaluation of a research diagnostic algorithm for DSM-5 neurocognitive disorders in a population-based cohort of older adults
TLDR
DSM-5 NCD criteria can be operationalized in a psychometric algorithm in a population setting and captured most cases with DSM-IV dementia and MCI, but included many additional cases suggesting that DSM-5 criteria are broader in their categorization.
Prevalence Rates of Dementia and Mild Cognitive Impairment Are Affected by the Diagnostic Parameter Changes for Neurocognitive Disorders in the DSM-5 in a Korean Population
TLDR
Diagnostic discrepancies between major/mild NCDs and dementia/MCI might depend on the operationalization of neuropsychological performance criteria.
Addressing neuropsychological diagnostics in adults with epilepsy: Introducing the International Classification of Cognitive Disorders in Epilepsy: The IC CODE Initiative
TLDR
A framework to develop a consensus‐based classification system for cognitive disorders in epilepsy that will be international in scope and be applicable for clinical practice and research globally is proposed and the International Classification of Cognitive Disorders in Epilepsy (IC‐CODE) project is introduced.
Lifting the veil: how to use clinical neuropsychology to assess dementia
TLDR
The pattern of deficits, helpful in defining clinical dementia phenotypes and sometimes in predicting the underlying molecular pathology, are outlined and will become invaluable as disease-modifying treatments for dementia are developed and implemented.
Dementia with criminal or socially inappropriate behavior - prevalence and consequence
TLDR
It can be concluded that criminal as well as socially inappropriate behavior is more prevalent in frontotemporal dementia (FTD) than in other neurodegenerative disorders.
Diagnosing Mild Cognitive Impairment as a Precursor to Dementia: Fact or Fallacy?
Mild cognitive impairment (MCI) describes a period of subclinical cognitive decline associated with an increased risk for the development of Alzheimer's disease (AD). However, research groups have

TLDR
These criteria for the diagnosis of vascular dementia are intended as a guide for case definition in neuroepidemiologic studies, stratified by levels of certainty (definite, probable, and possible).

TLDR
Clinical diagnostic criteria for probable and possible PD‐D are proposed, characterized by impairment in attention, memory, executive and visuo‐spatial functions, behavioral symptoms such as affective changes, hallucinations, and apathy are frequent.
Mild cognitive impairment as a diagnostic entity
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.

TLDR
This review deciphers this web of terminology and highlights consistent, and hence important, associations between individual clinical syndromes and neuropathology that could ultimately allow the identification of appropriate patient phenotypes for future targeted treatments.
Research criteria for the diagnosis of Alzheimer's disease: revising the NINCDS–ADRDA criteria
TLDR
These new criteria are centred on a clinical core of early and significant episodic memory impairment and stipulate that there must also be at least one or more abnormal biomarkers among structural MRI, molecular neuroimaging with PET, and cerebrospinal fluid analysis of amyloid beta or tau proteins.
