Several sets of diagnostic criteria have been published for vascular dementia since the 1960s. The continuing ambiguity in vascular dementia definition warrants a critical reexamination.
Participants at a special symposium of the International Society for Vascular Behavioral and Cognitive Disorders (VASCOG) in 2009 critiqued the current criteria. They drafted a proposal for a new set of criteria, later reviewed through multiple drafts by the group, including additional experts and the members of the Neurocognitive Disorders Work Group of the fifth revision of Diagnostic and Statistical Manual (DSM-5) Task Force.
Cognitive disorders of vascular etiology are a heterogeneous group of disorders with diverse pathologies and clinical manifestations, discussed broadly under the rubric of vascular cognitive disorders (VCD). The continuum of vascular cognitive impairment is recognized by the categories of Mild Vascular Cognitive Disorder, and Vascular Dementia or Major Vascular Cognitive Disorder. Diagnostic thresholds are defined. Clinical and neuroimaging criteria are proposed for establishing vascular etiology. Subtypes of VCD are described, and the frequent cooccurrence of Alzheimer disease pathology emphasized.
The proposed criteria for VCD provide a coherent approach to the diagnosis of this diverse group of disorders, with a view to stimulating clinical and pathologic validation studies. These criteria can be harmonized with the DSM-5 criteria such that an international consensus on the criteria for VCD may be achieved.

    • "International initiatives have outlined the relevance of the neuropsychiatric consequences of stroke and cerebrovascular diseases, and promoted consensus conferences [13], focused workshops [14], and the creation of an ad hoc scientific society [15], with the designation of new diagnostic criteria [16]. The definition, characterization, and treatment of the neuropsychiatric disturbances associated with stroke and cerebrovascular diseases are important from a clinical point of view, especially for patients and their families, and a more active role of stroke physicians in this relation has been advocated [17].

    ABSTRACT: Background and objective: Services dedicated to patients with cognitive and behavioral consequences of cerebrovascular diseases are not well established. In this paper, we report on the general organization of such a service (the Florence VAS-COG Clinic) after 9 years of activity, updating a previous work related to the first 5 years. Methods: The Florence VAS-COG clinic, started in 2006, is an outpatient service dedicated to the assessment and follow-up of patients with cerebrovascular diseases and related cognitive, psychiatric, and behavioral disturbances. The staff involved in the clinic is composed of certified neurologists, one neuropsychologist, and neurology residents. The diagnostic protocol includes detailed personal and family history, general and neurologic examinations, and functional, neuropsychological, and neuroimaging assessment. After this work-up, comprehensive diagnoses are made. Results: From January 2006 to March 2014, 600 patients (mean age 67.3 years ± 13.9; 52% females) have been evaluated in the clinic. Cognitive impairment, including mild cognitive impairment and dementia, mainly of vascular origin, was the most common (36.4%) diagnostic category, followed by suspected or confirmed familial micro-angiopathy (35.8%). Compared to the first years of activity, we are now facing the need of augmenting the number of visits due to increasing request and to better implement the multidisciplinarity of the team. Efforts are currently directed towards the definition of management protocols in pharmacological and non-pharmacological strategies. Conclusions: The establishment of a VAS-COG clinic represents an important step for the appreciation of the patient clinical needs and for the implementation of screening, diagnostic, and treatment options in the field of the neuropsychiatric consequences of cerebrovascular diseases.

    ABSTRACT: A major problem in elderly patients is the high incidence of multiple pathologies, referred to as multimorbidity, in the aging brain. It has been increasingly recognized that co-occurrence of neurodegenerative proteinopathies and other pathologies including cerebrovascular disorders is a frequent event in the brains of both cognitively intact and impaired aged subjects. Although clinical and neuropathological diagnostic criteria of the major neurodegenerative diseases have been improved, major challenges arise from cerebral multimorbidity, and the thresholds to cause clinical overt dementia are ill defined. More than 80 % of aged human brains show neurodegenerative non-Alzheimer type proteinopathies and other pathologies which, however, frequently have been missed clinically and are even difficult to identify at neuropathological examination. Autopsy studies differ in selection criteria and the applied evaluation methods. Therefore, irrespective of the clinical symptoms, the frequency of cerebral pathologies vary considerably: Alzheimer-related pathology is seen in 19-100 %, with "pure" Alzheimer's disease (AD) in 17-72 %, Lewy pathology in 6-39 % (AD + Lewy disease 9-28 %), vascular pathologies in 28-93 % (10.7-78 % "pure" vascular dementia), TDP-43 proteinopathy in 6-39 %, hippocampal sclerosis in 8-1 %, and mixed pathologies in 10-93 %. These data clearly suggest that pathologically deposited proteins in neurodegenerating diseases mutually interact and are influenced by other factors, in particular cardiovascular and cerebrovascular ones, to promote cognitive decline and other clinical symptoms. It is obvious that cognitive and other neuropsychiatric impairment in the aged result from a multimorbid condition in the CNS rather than from a single disease and that the number of complex pathologies progresses with increasing age. These facts have implications for improvement of the clinical diagnosis and prognosis, the development of specific biomarkers, preventive strategies and better treatment of cerebral multimorbidity.

    ABSTRACT: Post-stroke dementia (PSD) is a clinical entity but it now appears that most of PSD may be categorized as vascular dementia. The well-established relationship between vascular factors and dementia provides a rationale for the implementation of intervention and prevention efforts. Larger primary prevention trials related to lifestyle factors are warranted in association with dementia. Published clinical trials have not been promising and there is meager information on whether PSD can be prevented through the use of pharmacological agents. Control of vascular disease risk and prevention of recurrent strokes are obviously key to reducing the burden of cognitive decline and dementia after stroke. However, modern imaging and analysis techniques will help to elucidate the mechanism of PSD and establish better treatment.
