Conditions Treated

  • Neurologists at Rush are experts in managing PML and the long-term neurologic complications of any underlying conditions leading to its development.
  • Abdominal pain, also called stomach pain or belly pain, is pain below the chest and above the groin. It is a symptom and not a condition.
  • Abnormal Pap Smear

    Abnormal Pap smear occurs when a doctor finds abnormal cells from a Pap smear. Abnormal cells can indicate the presence of HPV or cancer, so it is critical to follow up with a gynecologist or primary care physician for further testing.
  • Achalasia is a rare disorder of the esophagus that drastically limits your ability to move food and liquids through your esophagus to your stomach.
  • A complete or partial tear tothe anterior cruciate ligament (ACL) — the part of the knee joint connecting the thigh bone to the shin bone can result from a hit on the side of the knee, overstretching the knee, or quickly stopping and changing direction while running, landing from a jump or turning.
  • Learn more about types of acne and the treatments available from leading pediatric and adult dermatologists at Rush University Medical Center.
  • An acoustic neuroma is a benign, often slow-growing tumor of the nerve that connects the ear and the brain. Also known as a vestibular schwannoma, the tumor can damage important nerves as it grows. This can affect hearing and balance.
  • Acromegaly

    Acromegaly is a rare condition usually caused by a tumor in the pituitary gland. In people who have it, the pituitary gland releases too much growth hormone. This can cause a variety of symptoms — including abnormal enlargement of the hands, feet or facial bones.
  • Leukemia is cancer that affects white blood cells, which grow in bone marrow and help fight infection. Acute lymphoblastic leukemia (ALL) prevents lymphoblasts, an immature type of white blood cell, from developing into mature lymphocytes. ALL cells accumulate and crowd out healthy blood cells.
  • Leukemia is cancer caused by white blood cells that develop abnormally in bone marrow. In acute myeloid leukemia (AML), myeloblasts, an immature type of white blood cell, multiply uncontrollably. They are unable to develop into mature myelocytes or function properly.
  • Leukemia is a type of cancer in white blood cells, which grow in bone marrow. Acute promyelocytic leukemia (APL) is a type of acute myeloid leukemia. It develops when promyelocytes, an immature type of white blood cell, grow abnormally and crowd out healthy blood cells.
  • Acute Respiratory Distress Syndrome (ARDS)

    Acute respiratory distress syndrome (ARDS) is a type of sudden respiratory failure, or inability to breathe normally. It usually results from injury to the lungs, such as pneumonia, trauma or the inhalation of harmful chemicals. It can be life-threatening and requires immediate medical attention.
  • Acute Respiratory Failure

    Acute respiratory failure occurs when abnormal breathing suddenly leaves blood with too little oxygen or too much carbon dioxide. It can result from stroke, spinal cord injury and many other conditions. Potentially life-threatening, acute respiratory failure can harm organs and requires immediate medical attention.
  • Addiction

    Addiction occurs when a person is unable to stop a particular behavior despite its negative effects on his or her health and personal life. Addiction can be physical (such as ingesting a substance like drugs or alcohol) or behavioral (such as repeatedly performing an action like gambling or sex).
  • Adrenal insufficiency occurs when your adrenal glands do not function properly. Adrenal glands, which sit on top of your kidneys, produce many hormones. Cortisol helps your body respond to stress. Aldosterone affects the balance of fluid in your body.
  • Alcoholic Liver Disease

    Alcoholic liver disease is liver damage due to alcohol abuse. Cirrhosis is the final stage of alcoholic liver disease. Alcoholic liver disease symptoms include digestive issues (like pain or swelling in the abdomen) and brain and nervous system issues (such as problems with thinking, memory or mood).
  • Alcoholism is an addiction to alcohol. Alcohol dependence is a disease that develops when a person’s alcohol consumption causes physical or mental health problems, or interferes with responsibilities to friends, family and employers.

    Amblyopia, also known as “lazy eye,” is a condition in which vision is reduced in one eye. Amblyopia is a treatable, common form of visual impairment in children.
  • Amyloidosis is a rare condition caused by the buildup of a protein called amyloid in one or more organs or tissues. Clumps of the abnormal proteins, called amyloid deposits, lead to damage of the affected area.
  • Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a rapidly progressing disease that attacks the nerve cells in the spinal cord that are responsible for controlling voluntary muscles.
  • Most anal cancers are squamous cell carcinomas that grow on the skin lining the inside of the anus. Anal cancer is rare and, if caught early, usually curable.
  • An anal fissure is a tear in the lining of the anus, or the lower part of the rectum, where stool passes out of the body.
  • Anemia occurs when you have a low number of healthy red blood cells, which provide oxygen to your body.
  • Angina is chest pain or discomfort that occurs when the heart isn’t receiving enough blood. It is a symptom of an underlying heart problem, usually coronary artery disease.

  • Anxiety is a feeling of uneasiness and apprehension over normal life stressors like beginning a new job or taking a test. When anxiety becomes overwhelming, it can interfere with a person’s physical and mental health and is then referred to as an anxiety disorder.
  • An aortic aneurysm is a bulging section in the aorta, the main artery that carries blood from the heart into the chest and abdomen.
  • Aortic stenosis is a narrowing of the aortic valve that decreases blood flow into the aorta, the main artery carrying blood out of the heart.
  • Aphasia is the total or partial inability to use or understand language. It is caused by a brain injury or illness that damages a language area of the brain.
  • Doctors at Rush have expertise in treating aplastic anemia, a rare and serious disease of the bone marrow.
  • Apraxia

    Apraxia is a disorder in which a person is not able to execute a task or movement, even though he or she is willing and physically capable of doing so. Apraxia is the result of damage to the brain. Apraxia can be caused by another condition, such as a stroke, brain tumor or dementia.
  • Arachnoid Cyst

    Arachnoid cyst is a benign (noncancerous) sac filled with fluid that develops in one of the tissues (arachnoid) covering the central nervous system. Arachnoid cysts can develop in the brain or spinal cord. Some arachnoid cysts will not cause any symptoms. If they do, arachnoid cyst symptoms include headaches, seizures, nausea and vomiting.
  • At the Rush Electrophysiology, Arrhythmia and Pacemaker Program, you'll find electrophysiologists who specialize in caring for heartbeat irregularities and provide second opinions. They offer all of the most advanced treatment options, including cardiac ablation and leadless pacing (e.g., Micra).
  • Arrhythmia in Children

    Learn what an irregular heart rhythm is, how it affects your child’s heart and what treatment options are available to return it to normal.

    Arrhythmia in Children
  • Arteriovenous Malformation

    Arteriovenous malformation (AVM) is an incorrectly formed tangle of arteries and veins. Normally capillaries connect the body’s veins and arteries. In an AVM, the capillaries are missing. This disrupts the body’s normal blood circulation process. AVMs can occur anywhere in the body but are more common in the brain and spine.
  • Ascites

    Ascites is when fluid builds up in the lining between your abdomen and abdominal organs. Ascites is more common in people who have liver damage, congestive heart failure or certain cancers in the abdominal region (including colon cancer, ovarian cancer and pancreatic cancer).
  • Asthma is inflammation of the airways in your lungs.
  • Asthma in Children

    What is asthma in children?

    Asthma in children occurs when irritants like allergies, exercise and cigarette smoke cause airways — the tubes that carry air to and from the lungs — to become inflamed and fill with mucus. This inflammation makes your child’s airways more sensitive and narrow, causing coughing, wheezing and shortness of breath.

    While there is currently not cure for asthma, some children grow out of it. There are also a number of treatments and lifestyle changes that can help you and your child manage asthma and prevent flare-ups.

    Asthma in Children
  • Astigmatism

    Astigmatism is a common vision condition that causes blurred vision. Astigmatism is known as a refractive error because it affects how the eye bends or “refracts” light. It frequently occurs with nearsightedness (myopia) or farsightedness (hyperopia).
  • The brain cancer team at Rush offers advanced, compassionate care for astrocytomas, a type of brain or spinal cord tumor.
  • Ataxia

    Ataxia refers to clumsy or uncoordinated movement. It frequently appears as uncoordinated walking or balance difficulties and can occur in children or adults. Ataxia can be progressive and associated with other medical problems, such as heart disease.
  • Atopic dermatitis, also known as eczema, is a very common skin condition. It often starts with an itch. Scratching results in a rash — dry, red patches that in some people may bubble and ooze.
  • Atrial fibrillation, the most common type of arrhythmia, is a serious condition that causes an irregular, and often fast, heartbeat. This makes the heart pump blood less effectively, weakening the heart and potentially leading to blood clots, stroke or congestive heart failure.
  • Attention deficit-hyperactivity disorder (ADHD) inhibits the ability to focus and control impulses. People with ADHD may also be overly active. Many call this condition attention deficit disorder, or ADD.
  • Autism spectrum disorder (ASD) is a neurodevelopmental disorder that appears in early childhood and continues throughout a person’s life. Signs of ASD typically appear before age 3, but symptoms sometimes are not noticed until later.
  • Autism in Children

    Autism spectrum disorder (ASD) is a neurodevelopmental disorder that appears in early childhood and continues throughout a person’s life. Signs of ASD typically appear before age 3, but symptoms sometimes are not noticed until later.

    Autism in Children
  • Autoimmune Disorders

    Autoimmune disorders are when a person’s immune system attacks healthy tissue and destroys it. Sometimes referred to as autoimmune diseases, these disorders include lupus, multiple sclerosis and rheumatoid arthritis.
  • Autoimmune Hepatitis

    Autoimmune hepatitis is when a person’s immune system attacks the healthy cells of the liver, causing inflammation. Autoimmune hepatitis can lead to cirrhosis and liver failure. Common autoimmune hepatitis symptoms include fatigue, dark-colored urine, itchiness and abdominal discomfort. Autoimmune hepatitis is an autoimmune disease.
  • Avascular necrosis (also called osteonecrosis) occurs when blood flow to bones in the joints is disrupted. Deprived of blood, the bone eventually starts to die and may eventually collapse.
  • The two types of back pain are acute, which typically occurs after a fall, injury or heavy lifting, and chronic, which persists for three months or longer.
  • Bacterial vaginosis occurs when bacteria start to overgrow in the vagina, sometimes causing symptoms such as vaginal itchiness and odor.
