Hereditary cerebral amyloid angiopathy, Icelandic type
Overview
Hereditary cerebral amyloid angiopathy is a genetic condition that leads to a loss of brain function. There are many types of this disease, with each one having slightly similar symptoms. The Icelandic type (which is named after the country where it was first diagnosed) is genetic and usually causes a stroke in your 20’s or 30’s, followed by dementia. Other symptoms can include nausea, headache, vomiting, or loss of consciousness (passing out). This condition is caused by a mutation in the cystatin 3 gene, which means that the disease is passed down in families. The mutation causes amyloid deposits in the brain than can lead to the stroke and decreased brain function.
Hereditary cerebral amyloid angiopathy is diagnosed with genetic testing, and can be detected before symptoms start to occur. As of now there is no way to prevent this disease, and there is no recommended treatment. If you or a family member has been diagnosed with hereditary cerebral amyloid angiopathy, talk to your doctor about the most current treatment options. Support groups are also good resources for information.
