Answer

Amyloid angiopathies are also known to increase risk for stroke and dementia. Mutations in the CST3 gene are causative and are inherited in an autosomal dominant manner. Sufferers will have diffuse deposition of amyloid, including in the brain. The onset of symptoms is typically in the third or fourth decade of life, with death occurring before age 60 years. These angiopathies appear to be most common in the Icelandic population. [31]
