Glossary for Cerebral Aneurysm

  • Aneurysm: Dangerous ballooning of a weakened area of an artery
  • Atherosclerosis: Atherosclerosis is a syndrome affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part due to the accumulation of macrophage white blood cells and promoted by low density (especially small particle) lipoproteins (plasma proteins that carry cholesterol and triglycerides) without adequate removal of fats and cholesterol from the macrophages by functional high density lipoproteins (HDL). It is commonly referred to as a hardening or furring of the arteries. It is caused by the formation of multiple plaques within the arteries.
  • Blood vessel symptoms: Symptoms affecting the blood vessels
  • Brain conditions: Medical conditions that affect the brain
  • Brain symptoms: Symptoms affecting the brain
  • Cerebral Arteriosclerosis: Hardening or blockage of arteries in the brain.
  • Cerebrovascular Conditions: Conditions of the brain's blood vessels including stroke.
  • Cerebrovascular symptoms: Symptoms related to the brain's arteries
  • Circulatory system conditions: Medical conditions affecting the heart and the circulatory system.
  • Congenital conditions: Any condition that you are born with such as birth defects or genetic diseases.
  • Ehlers Danlos syndrome type 4, autosomal dominant: A rare genetic connective tissue disorder characterized by delicate skin, fragile blood vessels, distinctive facial features and minimal joint problems - previously known as EDS type 4.
  • Head Conditions: Conditions that affect the head
  • Head injury: An injury to the head
  • Headache: In medicine a headache or cephalalgia is a symptom of a number of different conditions of the head and sometimes neck. Some of the causes are benign while others are medical emergencies. It ranks among the most common pain complaints
  • Hemiparesis: One-sided paralysis of the body
  • Hydrocephalus: A rare condition where the normal flow of cerebrospinal fluid is impaired by dilated brain ventricles which causes the fluid to accumulate in the skull and hence result in increased brain pressure.
  • Hypertension due to coarctation of the aorta: Hypertension due to coarctation of the aorta is high blood pressure resulting from a birth defect where a heart blood vessel called the aorta is abnormally narrowed. The high blood pressure tends to affect mainly the upper part of the body. Babies and very young children tend to have more severe symptoms as the degree of narrowing tends to be greater than in older children or adults.
  • Impaired vision: Reduced or degraded vision.
  • Intracranial aneurysms -- multiple congenital anomaly: A very rare syndrome characterized mainly by brain aneurysms (dilated blood vessel) and various other abnormalities.
  • Nausea: The queasy feeling of nausea and often also vomiting.
  • Nervous system conditions: Diseases affecting the nerves and the nervous system.
  • No symptoms: The absence of noticable symptoms.
  • Nuchal rigidity: nuchal rigidity or neck stiffness is tested by placing the examiner's hand under the patient's head and gently trying to flex the neck. Undue resistance implies diffuse irritation of the cervical nerve roots from meningeal inflammation
  • Osler's disease: Genetic disease causing multiple teleangiectasias
  • Polycystic kidney disease: Genetic kidney disease causing kidney cysts.
  • Polycystic kidney disease, adult type: A rare condition where cysts in the kidney grow and cause the kidney to become larger and reduce it's ability to function. PKD 2 is an autosomal dominant form of the disease and differs from PKD 1 in that it is less severe and is caused by a mutation in a different gene.
  • Polycystic kidney disease, type 2: A rare condition where cysts in the kidney grow and cause the kidney to become larger and reduce it's ability to function. This adult form of the condition is milder than the infantile form.
  • Stroke: Serious brain event from bleeding or blood clots.
  • Subarachnoid hemorrhage: Brain bleeding in the subarachnoid area
  • Syncope: Temporary loss of conciousness or fainting.
  • Vomiting: Vomiting or retching symptoms.
