1. Moyamoya
Moyamoya disease is a very rare type of vascular disorder. The word moyamoya is Japanese, and it translates into English as ‘a puff of smoke’. The name was given because of the appearance of the condition when seen on an X-ray. Patients with the condition will have a carotid artery that is narrower than usual.
This causes more blood vessels to be formed at the base of the brain to try and compensate for the lower than usual blood supply. The disease can affect people of all ages, but children are most likely to be affected by it. while it is found worldwide, it is more common in China, Japan, and Korea.
