The first steps to create an organisation devoted to vascular causes of cognitive and behavioural disorders were taken during autumn 2001 when researchers started to discuss the need to have a society which could organise meetings and working groups. The discussions became more formal at a meeting in Madrid later that year in November on Vascular Burden of the Brain: New Therapeutic Directions, organised by the International Psychogeriatric Association.
At that meeting a manifesto was drafted (see below) and sent out to researchers interested in the subject. This manifesto was soon signed by a large number of researchers from different parts of the world (see Founding members). It was also decided that the first meeting was to be held in Gothenburg, Sweden in August 2003 (VASCOG 2003).
During spring 2002, after discussions and a final voting among the founding members, it was decided that the name of the society should be the International Society for Vascular Behavioural and Cognitive Disorders (VasCog). In April 2002, at the 3rd World Congress on Vascular factors in Alzheimer's Disease held in Kyoto, Japan, it was decided that in future this Congress should be incorporated into the VasCog meetings.
During autumn 2002 the members of the Society discussed and finally approved the by-laws of the society, first drafted by Julien Bogousslavsky and Ingmar Skoog.
During Spring 2003 the members decided after voting that the 2nd Congress should be held in Florence, Italy 2005. The first Executive Committee of Vas-Cog was elected during the summer of 2003, and had its first meeting during VASCOG 2003 in Gothenburg.
To investigate vascular factors related to brain injury and dysfunction through their manifold causes and presentations and to strive for consensus on vascular involvement in psychiatric, psychological, cognitive, behavioural, and functional symptoms.
The principle goal of the society is to raise awareness through regular scientific meetings on the topic and facilitate the attendance of younger researchers at such meetings.
- Encourage worldwide representation
- Involve a multidisciplinary approach
- Stimulate research and debate
- Encourage integration and participation of young researchers
- Disseminate and translate results to clinical practice
- Advance public education and awareness
- Develop liaison with caregivers
- Organise and host biennial international meetings
- Hold focused workshops
Message from the previous president Vladimir Hachinski
What is being done
One in three individuals will end up with a stroke, dementia or both1 unless we improve prevention. Moreover, for each person over the age of 65 years who has had a stroke or dementia, two have some cognitive problem short of dementia2 .At the moment, the major emphasis is on the late stages, and the extremes i.e. stroke and dementia. That leaves a neglected majority whose problems are seldom addressed, because they may not be severe enough to prompt medical attention or if the complaints are aired, they may be dismissed as attributable to old age.
Although it is becoming increasingly evident that depression can be associated with certain types of cerebral infarcts and white matter changes, we are yet to work out an anatomy of melancholy and provide a neuroscientific bases for addressing what remains a major problem.
WHAT VAS-COG CAN DO
Most knowledge accrues in pieces but is understood in patterns. Most organizations specialize in areas that themselves get subdivided “ad infinitum”. Vas-Cog may be the only organization that tries to integrate knowledge and understand the broad spectrum of cognitive disorders. It emphasizes the vascular factors, which are potentially treatable and provide means towards preventing, mitigating or delaying all types of cognitive disorders, including Alzheimer disease. Cerebrovascular and Alzheimer disease share the same vascular risk factors.
Focusing on stroke and dementia has been achieved to the relative neglect of the prodromal and intermediate stages. Stroke investigators have little interest in cognition, and dementia investigators even less in stroke.
Even if stroke and dementia investigators did have a reciprocal interest in the two areas, there has been no agreement on common data elements. Dementia criteria can vary in their identification of the same set of patients by a factor of 10!3
Vas-Cog established working groups to try to develop common minimal standards. This endeavor took a leap forward when Dr. Gabrielle Leblanc, Dr. Costantino Iadecola and Dr. Vladimir Hachinski organized a symposium with the leadership, participation or contributions from members of the different working groups of Vas-Cog, so that now exist minimum recommended standards for the whole spectrum of cognitive impairment.4 The advantage of using common data elements is that several provisional criteria can be tested simultaneously and modified many times according to outcomes, as knowledge grows.
The San Antonio Congress in July 11-14, 2007 proved extensive, intensive and very interactive. Through the initiative of Dr. Gustavo Roman, a Declaration of San Antonio was issued calling for the public, the drug industry, government, investigators and patients to become aware of the growing burden of brain disease attributed to vascular injury and to do something about it. (below)
The emphasis needs to shift from effects to causes of cognitive and behavioural disorders. Therein lie the best hopes of treatment and prevention.
It may be time for a trial in prevention and/or delay of cerebrovascular and Alzheimer disease by randomizing family practices and/or communities to usual care or optimal care of vascular risk and protective factors. Vas-Cog has established a working group with the specific task of producing a proposal and discussion paper for publication that outlines the need and means of implementing such a study.
WHAT CAN YOU DO?
1. Join Vas-Cog.
2. After you have joined, have someone else join.
3. Join a working group.
In addition to a working group on prevention, there are working groups on neuropsychology and mechanisms of vascular cognitive impairment. If you have an idea for another working group, please write me with suggestions about the topic and individuals who may lead it.
Advances occur not by breakthroughs alone, but also by many people making small advances cumulatively contributing as much as the few who make major advances. No-one’s work is important simply because it is sophisticated, nor valueless because it is humble. We can all improve what we do. We can all make a difference. Let’s make a difference!

4.3. The Society will also be composed of associate members. Persons interested in becoming associate members shall send to the Secretary General their full application material. As a new associate member may be accepted any individual who has a past and present record of clinical activity or research in the field. The Secretary General will then register them as associate members. The applicant can also apply for 'active membership' as stated in paragraph 4.2. They will then be associate members until their status as active members is approved by the Executive Committee
Other categories of membership could be e.g.
*'research students' (research students who have yet not established themselves to be able to be active members)
*other persons who are interested in the area but do not fulfil the requirements for active membership
