Clinical Information

• Pneumocephalus

  presence of air or gas within the intracranial cavity (e.g., epidural space, subdural space, intracerebral, etc.) which may result from traumatic injuries, fistulous tract formation, erosions of the skull from neoplasms or infection, neurosurgical procedures, and other conditions.

• Celiac Disease

  a malabsorption syndrome that is precipitated by the ingestion of foods containing gluten, such as wheat, rye, and barley. it is characterized by inflammation of the small intestine, loss of microvilli structure, failed intestinal absorption, and malnutrition.

• Slit Ventricle Syndrome

  an intermittent and self-limiting headache disorder in individuals with cerebrospinal fluid shunts emplaced for the treatment of hydrocephalus. the symptoms of headache, vomiting, and cranial neuropathies are associated with intermittent obstruction of the shunt.

• Automatism

  automatic, mechanical, and apparently undirected behavior which is outside of conscious control.

• Encephalomalacia

  softening or loss of brain tissue following cerebral infarction; cerebral ischemia (see brain ischemia), infection, craniocerebral trauma, or other injury. the term is often used during gross pathologic inspection to describe blurred cortical margins and decreased consistency of brain tissue following infarction. multicystic encephalomalacia refers to the formation of multiple cystic cavities of various sizes in the cerebral cortex of neonates and infants following injury, most notably perinatal hypoxia-ischemic events. (from davis et al., textbook of neuropathology, 2nd ed, p665; j neuropathol exp neurol, 1995 mar;54(2):268-75)

• Leukomalacia, Periventricular

  degeneration of white matter adjacent to the cerebral ventricles following cerebral hypoxia or brain ischemia in neonates. the condition primarily affects white matter in the perfusion zone between superficial and deep branches of the middle cerebral artery. clinical manifestations include vision disorders; cerebral palsy; paraplegia; seizures; and cognitive disorders. (from adams et al., principles of neurology, 6th ed, p1021; joynt, clinical neurology, 1997, ch4, pp30-1)

• AVPR2 wt Allele|ADHR|Arginine Vasopressin Receptor 2 (Nephrogenic Diabetes Insipidus) Gene|Arginine Vasopressin Receptor 2 wt Allele|DI1|DIR|DIR3|NDI|V2R

  human avpr2 wild-type allele is located within xq28 and is approximately 5 kb in length. this allele, which encodes vasopressin v2 receptor protein, is involved in the maintenance of water homeostasis and g protein-coupled receptor signal transduction. when the function of the gene is absent, it results in nephrogenic diabetes insipidus (ndi).

• Nephrogenic Diabetes Insipidus

  diabetes insipidus caused by insensitivity of the kidneys to antidiuretic hormone.

• Pneumocephalus

  the presence of air or gas within the cranial cavity.

• Cerebral Calcification

  abnormal deposits of calcium in the cerebral tissue.

• Encephalomalacia

  localized atrophy of the brain parenchyma due to aging, hemorrhage, infarct, or inflammation.

Patient Education

Brain Diseases

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body. Your nerves take in information from your senses and send it to the brain to be processed. Your brain and nerves also communicate to help you move and to control your body's functions.

When the brain is healthy, it works quickly and automatically. But when you have a brain disease, it may affect how well you can function and do your daily activities. Some common brain diseases include:

• Brain tumors, which can press on nerves and affect brain function.
• Degenerative nerve diseases, which can affect many of your body's activities, such as balance, movement, talking, breathing, and heart function. Types include Alzheimer's disease and Parkinson's disease.
• Encephalitis (inflammation in the brain), which can lead to problems such as vision loss, weakness, and paralysis.
• Genetic brain disorders, which are caused by changes in genes (also called variants or mutations). These disorders can affect the development and function of the brain.
• Strokes, which can cause a loss of brain cells and can affect your ability to think clearly.
• Traumatic brain injuries (TBIs), which can affect brain function. They may range from mild to severe. The effects of a TBI may be temporary or permanent.

The symptoms of brain diseases vary widely, depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or therapies such as physical, occupational, and speech therapies, may cure the disease or improve the symptoms.
