Overview
Genetic cerebral small vessel disease (also called hereditary cerebral small vessel disease or genetic CSVD) is a group of inherited conditions that affect the tiny blood vessels deep inside the brain. These small vessels, when damaged by genetic changes, can no longer carry blood properly to brain tissue. Over time, this leads to areas of injury in the brain's white matter — the network of nerve fibers that connects different brain regions. The damage builds up slowly and can cause a wide range of problems with thinking, movement, and mood. The most well-known forms include CADASIL (caused by NOTCH3 gene changes), CARASIL (caused by HTRA1 gene changes), COL4A1/COL4A2-related disease, and several others. Each form has its own genetic cause, but they share many overlapping symptoms. Common symptoms include migraines (especially with aura), small strokes or stroke-like episodes, memory and thinking problems, mood changes, difficulty walking, and in some forms, early hair loss or back pain. There is currently no cure for genetic cerebral small vessel disease. Treatment focuses on managing symptoms, reducing stroke risk factors like high blood pressure, and supporting quality of life through rehabilitation. Research is ongoing, and some gene-specific therapies are being explored. Early diagnosis through genetic testing and brain MRI is important so that people can get the right care and monitoring as early as possible.
Key symptoms:
Migraines, often with visual disturbances (aura)Small strokes or transient ischemic attacks (mini-strokes)Memory loss and difficulty concentratingMood changes, depression, or personality changesDifficulty walking or problems with balanceMuscle stiffness or weaknessBladder control problemsGradual decline in thinking and reasoning skills (dementia)Fatigue and low energyBack pain and stiff spine (in CARASIL)Early hair loss (in CARASIL)Seizures (in some forms)Vision problemsPsychiatric symptoms such as anxiety or apathy
