Brain Tumor Complications

Every brain tumor is unique, and patients present with a variety of complications, depending on the type and location of the tumor. Some brain tumor complications are common in multiple types of tumors, and others are only associated with one type of brain tumor. For example, brain tumor headaches are one of the most common complications for all brain tumor patients.
Many different types of rehabilitation are available for patients who suffer from brain tumor complications. Physicians and therapists can help patients improve their quality of life before, during and after brain tumor treatment.

Brain Tumor Seizures and Other Complications

Brain tumors may cause a myriad of problems, including:
  • Decreased sensation
  • Depression
  • Difficulties with walking or speech
  • Headaches
  • Hearing problems, such as ringing or loss
  • Lack of coordination or balance
  • Loss of ability to interact or function
  • Loss of brain function
  • Loss of, or change in, vision
  • Personality changes
  • Return of tumor
  • Seizures
  • Weakness or paralysis.
Some brain tumor complications can be very serious or even fatal. Severe complications include:
  • Herniation
  • Hydrocephalus
  • Increased Intracranial Pressure (IICP)
  • Stroke.

Severe Brain Tumor Complications

In cases of brain tumor herniation, pressure from the tumor alters the normal position of brain tissue. Herniations are common complications of brain tumors and may lead to:
  • Cardiac arrest
  • Coma
  • Irregular breathing
  • Irregular pulse
  • Loss of brain stem reflexes (blinking, gagging).
Hydrocephalus is the accumulation of cerebrospinal fluid (CSF) in the cavities of the brain, which occurs when the tumor obstructs the flow of CSF. Pressure from swelling or the growth itself impairs proper functioning of the central nervous system. Symptoms include:
  • Irritability
  • Lethargy
  • Nausea
  • Seizures
  • Tiredness
  • Vision problems
  • Vomiting.
Increased Intracranial Pressure (IICP) can lead to hydrocephalus or herniation. Symptoms include:
  • Drowsiness
  • Headache
  • Nausea
  • Personality changes
  • Swollen optic nerve
  • Visual changes or problems, such as double vision
  • Vomiting.
Stroke is a rapid decrease in function of the brain resulting from a blocked or burst blood vessel. It may result in one or more of the following symptoms:
  • Impairment or complete loss of vision
  • Inability to speak or understand others
  • Paralysis.
Brain tumor complications also include side effects from treatments for the tumor, such as fatigue or nausea from chemotherapy drugs.

Pernicious Anemia: Vitamin B12 Deficiency

Image
Anemia  is a blood disorder in which the number of red blood cells or the amount of hemoglobin is lower than normal. With fewer red blood cells or hemoglobin, insufficient oxygen is delivered to the body 's cells. Pernicious anemia  is a type of anemia caused by a deficiency in vitamin B12. In pernicious anemia, the lack of vitamin B12 is due to the body 's inability to produce enough  intrinsic factor , a protein necessary for the absorption of vitamin B12. Pernicious anemia is a type of  megaloblastic anemia . Megaloblastic anemia is defined as, "a blood disorder characterized by anemia, with red blood cells that are larger than normal, usually resulting from a deficiency of folic acid or of vitamin B12 .  " (U.S. National Library of Medicine) Pernicious anemia by any other name . . . Pernicious anemia is known by a number of other names, including: macrocytic achylic anemia congenital pernicious anemia juvenile pernicious anemia vitamin B12 deficienc

Nutrition & Cystic Fibrosis

Image
Cystic fibrosis is a genetic disorder that affects the body's exocrine glands, including the various mucus and sweat glands found throughout the body. Since cystic fibrosis is an inherited disease, most people with the disease are usually diagnosed by their first birthday. The most common problems due to cystic fibrosis are related to the lungs and the digestive system. In the lungs, the mucus produced by the various exocrine glands is abnormally thick, creating obstructions in the breathing passageways and, eventually, damage to the lungs. Furthermore, the thick mucus creates an ideal breeding ground for various bacteria and other organisms, which results in frequent lung infections, damage to the lungs and, ultimately, respiratory failure. Cystic fibrosis also affects the pancreas. The pancreas is responsible for producing various enzymes to aid in digestion, but in cystic fibrosis the pancreas is unable to excrete sufficient amounts of pancreatic enzymes to help digest foo
