Greetings from Vas-Cog Japan, the JapaneseSociety for Vascular Cognitive Impairment

program at a great venue organized by the chairmen.  
The 9th annual meeting is to be held at Beppu
International Convention Center August 4-5, 2018,with Dr. Katsuya Urakami and Dr. Etsuro Matsubara
as chairmen, so we are expecting many of you toattend.
Our affiliate Vas-Cog Asia has been revitalizing
year by year. The 6th meeting held in Nanjing City
on October 26, 2017, was a huge success with VasCog Asia Director, Dr. Koji Abe and Dr. Shinichiro
Uchiyama serving as lecturers and moderators.  The7th annual meeting will be held in Jakarta on
September 6, 2018. Vas-Cog World will also be heldin Hong Kong November 24-27, 2018.
With regard to the major dementias such as Lewy
body dementia, Parkinsonʼs Disease-related dementia
and frontotemporal dementia, as well as the rapidly
increasing Alzheimerʼs Disease (AD) and vasculardementia, Vas-Cog Japan has been established toelucidate the relationship between blood vessels anddementia that are attracting attention in our rapidly
aging society with the aim of advancing clinical andfundamental research from a new broader viewpoint
beyond the concept that it is merely a vasculardementia as classified conventionally.
As the government has set the era of a lifetime at
one hundred years, prevention and treatment ofdementia is becoming a top priority task, such as thedevelopment of health care strategy for a one-year
extension of life expectancy by 2020.   In addition,
Japan is bidding to host the World Exposition in
Osaka in 2025
In response to such new academic and social
demands, our society will continue to elucidate thedeep linkage between functional and organic
obstacles in blood vessels and the onset of dementia,
and will develop new diagnostic and therapeutic
methods. By doing so, we aim to contribute to themaintenance and development of a healthily aging
society of all human beings, including Japanese.
Our society has developed steadily under theleadership of former Presidents Dr. Nagata and Dr.
Abe.   It is a unique academic society that covers awide variety of interdisciplinary fields such as
cardiology, neurology, and brain surgery through theactive participation of everyone, so we are looking
forward to the participation of many of you.

April 1, 2018

I am Dr. Ryuichi Morishita from Osaka University,and I took over as President of the Japanese Society
for Vascular Cognitive Impairment from Dr. Koji Abe.  
I would like to further develop this society - which
was first developed by Dr. Nagata, the first President,
and Dr. Abe, the second President - to the best of myability, with the cooperation of all the members inour society, so your kind support would be greatly
appreciated.
Vas-Cog Japan, which is in its eighth year from its

considerably.   As our society has already met therequirements to be registered as an academicorganization in the Science Council of Japan withregard to the number of members, membershipmanagement and publication of journals, theChairman for the Promotion of Becoming a Society,
Dr. Katsuya Urakami, has been working on ourapplication for the registration.
Also, our newsletter, which was first published in2016 in Japanese and English, has been distributed
to related academic societies in various countries
and is well received thanks to the hard work byformer President Dr. Abe. Fortunately, thanks to theefforts of the Chief Editor of the academic magazine,
Dr. Mikio Shoji, it has developed into Vas-Cog
Journal, a joint publication with Vas-Cog Asia.
In addition, the number of members also increased
steadily due to the efforts of the Chairman for
Increasing Membership and Public Relations, Dr.
Haruo Hanyu.   As of August 2017, we have 143
active members, including 26 directors and 54
councilors and the membership is expected toincrease in the future.   Furthermore, the financial
structure has been going very well.  I sincerely thankthe members, councilors, and directors who havesupported this society for all these achievements.
I would like to continue to strengthen the financial
structure under the guidance of Dr. Yoshio Ikeda,
who is the newly appointed Chairman of Financial
Affairs. Regarding conflicts of interest, we plan to set
up a COI committee and prepare provisions under
the direction of the Chairman, Dr. Masahiko Suzuki.
The 8th Annual Meeting of Vas-Cog Japan washeld with great success on August 5, 2017, at
Toranomon Hills, with Dr. Shinichiro Uchiyama and
Dr. Issei Komuro as chairmen. I believe that many
participants were satisfied with the very attractive2 JAPANESE SOCIETY OF VASCULAR COGNITIVE IMPAIRMENT（2018 NO.4）
