Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine. CCMs can bleed and cause strokes, seizures, and headaches. CCMs are often caused by an inherited gene mutation (alteration) in one of three CCM genes (CCM1, CCM2, or CCM3). There is a wide range of disease severity even among family members with this disease, though the natural history has not been clearly described for this particular population.

This study will continue to enroll and follow participants with familial CCM to identify factors that influence CCM disease severity and progression, focusing on barriers to clinical trial preparedness. Our long-term goal is to identify measurable outcomes and robust biomarkers that will help select high-risk patients and help monitor drug response in future clinical trials.

The specific goals of this study are to:

* Identify factors that influence lesion progression to symptomatic hemorrhage and other outcomes, including quality of life;
* Investigate the role of the gut microbiome and lesion burden in CCM disease, and
* Identify blood biomarkers predictive of CCM disease severity and progression for clinical trials.

This study is one of three projects participating in the Brain Vascular Malformation Consortium (BVMC) funded by the Office of Rare Diseases Research, which is part of the National Center for Advancing Translational Sciences (NCATS), and the National Institute of Neurological Disorders and Stroke (NINDS).

The CCM project is a cross-sectional and longitudinal study of familial CCM patients. The study is currently in the third 5-year cycle. During the first 5 year cycle (BVMC1), the CCM project was focused on recruiting CCM1 cases with the common Hispanic mutation (CHM). In the second 5-year cycle (BVMC2), we expanded recruitment to include not only CCM1-CHM cases, but also other CCM familial patients and mutation carriers. In the third 5-year cycle (BVMC3), we will continue to recruit familial CCM cases and expand to additional recruitment sites.

We collect clinical, genetic, imaging, treatment, and outcome data in participants, and follow enrolled participants over time to understand the natural history of this disease.

For new study participants, you will be asked to:

* Give permission for study staff to access your medical records to collect clinical information and to obtain copies of MRI scans and reports.
* Fill out a questionnaire about your quality of life, family history, and medical/surgical history.
* Give a blood and/or saliva sample, and stool sample.
* Give permission to store and use your CCM resected tissue for research (if undergoing surgery).
* Participate in annual follow-ups to update medical, surgical, and neurological information.

Eligible cases include those with a known genetic mutation in one of the three CCM genes or those that meet 2 of 3 following clinical criteria:

1. Clinical diagnosis of CCM,
2. Multi-focal lesions on MRI, and/or
3. Family history of CCMs.

Exclusion Criteria:

1. Patients who cannot or are unwilling to sign informed consent and for whom no appropriate surrogate is available.
2. Prisoners and homeless individuals because of the inability to contact the subject and collect follow-up data using standard procedures.

We will collect stool specimens in newly recruited familial CCM cases. We collect and store saliva as well as whole blood for DNA, RNA, and plasma or serum samples. Brain cavernous malformation tissue will be collected and banked as available.

Modifiers of Disease Severity and Progression in Cerebral Cavernous Malformations

Available data will be released to the Rare Diseases Clinical Research Network repository and will become available to the scientific community one year after publication of planned analyses, or after a period of 5 years from the date when the data were collected, whichever comes first

Standardized patient reported outcome measurement tools to assess pain, fatigue, physical function, emotional distress, and social participation.

The number of lesions (or cavernous angiomas) located in the brain will be counted by a neuroradiologist and by an automated algorithm developed as part of this project.

Symptomatic hemorrhage is defined as diagnostic evidence of new lesional bleeding or hemorrhagic growth, in association with directly attributable symptoms. Rate of symptomatic hemorrhage and the factors that influence hemorrhage rates will be assessed.

The number of lesions (or cavernous angiomas) counted on the baseline MRI will be compared to the number of lesions observed in follow up MRIs.

The modified Rankin score will be assessed at baseline and at approximately one year intervals while remaining in study

Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine. CCMs can bleed and cause strokes, seizures, and headaches. In some patients, CCMs affect the blood brain barrier (BBB). The BBB is the body's separation of blood and its contents in the brain from the brain tissue itself. Abnormal leakiness or permeability of this barrier can cause disease. We will measure the permeability (leakiness) of the BBB using a magnetic resonance imaging (MRI) technique called dynamic contrast-enhanced MRI (DCEMRI). The purpose of this study is to look at whether statin medications change the permeability (leakiness) of the blood brain barrier in CCM patients. Statin medications are used to lower cholesterol levels and prevent heart attack and stroke. In addition, this medication may decrease the risk of brain hemorrhage or bleeding in patients with CCM. This study will examine whether the permeability of the BBB changes following the administration of simvastatin for three months.

Permeability MRI in Cerebral Cavernous Malformations Type 1 in New Mexico: Effects of Statins

We will measure the change in blood brain barrier permeability with dynamic contrast enhanced MRI from baseline to three months. We will compare the change in permeability for a group of CCM patients placed on statin medication (treatment group) with a group of CCM patients not on statin medication (control group).

Use dynamic contrast-enhanced MRI to detect abnormalities in brain permeability in CCM patients and correlate with anatomic lesion information.

Surgical removal of intracerebral CMs by craniotomy with or without following stereotactic radiosurgery.

Observation with the best medicine administration and supportive treatment are performed.

For patient in surgically treated group, surgical removal of intracerebral CMs by craniotomy is performed according to the principles as follows: less transgression of normal brain tissue; identification and protection of eloquent brain tissue; sparing associated developmental venous anomaly; hemosiderin rim resection for non-eloquent and superficial CMs and sparing yellowish tissue for eloquent and deep ones; Extended resections (mesial resection, standard temporal lobe resection) are recommend for epileptogenic CMs based on intra-operative EEG.

Surgery

Observation is performed in conservatively treated patients with best medicine and supportive treatment, such as antiepileptic drugs, analgesic drugs and neurotrophic drugs. For patients with underlying diseases such as hypertension, hyperlipidemia or diabetes mellitus, after consulting with the relevant experts, the patients can be treated accordingly.

This nationwide multicenter prospective cohort study will collect the treatment information and outcomes of the patients with previously untreated cavernous malformations (U-CMs) in China (at least 2000 patients from 20 centers). The investigators aim to determine the effect of different treatments on long-term outcomes in patients with untreated cerebral cavernous malformations.

Despite the availability of microsurgical excision and stereotactic radiosurgery for cavernoma treatment and known genetic causes of most familial forms of cavernoma, uncertainties remain about cause, diagnosis, prognosis, treatment, and care. According to the recently published CM treatment guideline, surgical and conservative treatments are both first-line therapeutic options in previously untreated CMs (U-CMs). However, given current data, neurosurgeons are still unable to counsel patients on which would be the best option. To address the absence of high level evidence to support cerebral CM treatment decisions, there is a need for a large sample size study of cerebral CM treatment with a prospective concurrent group. China has the largest population in the world and may have the most extensive and valuable clinical resources of U-CMs. But, till now, the current treatment and outcome situation of the disease in China is not well known. Thus, the investigators are conducting a nationwide multicenter prospective registry study in China to determine the effect of different treatments on long-term outcomes in patients with untreated cerebral cavernous malformations.At least 2000 patients with untreated cerebral cavernous malformation will be enrolled from 20 Grade Ⅲ A level hospitals distributed all over China. Clinical data and laboratory data are prospectively collected by electric case report form (CRF) and uploaded online by each neurosurgery center to form the prospective clinical database in First Affiliated Hospital of Fujian Medical University. This is a cohort follow-up study across a 5-year period with a 2 years interval of enrollment and 3 years follow up for each patient.
