Definiton
The oligodendroglioma belongs to the group of brain tumors and is usually benign. The most frequent occurrence of the oligodendroglioma is at the age of 25-40 years. Oligodendrogliomas are tumors that develop from certain cells of the brain.
These cells are called oligodendrocytes; they surround the nerve cells in the brain and serve as a supporting framework. They are also responsible for the transport of substances and fluids. Oligodendrogliomas can be divided into four different stages.
The higher the level, the more malignant they are. A distinction is made between: benign oligodendrogliomas, grade I low malignant oligodendrogliomas, grade II anaplastic oligodendrogliomas, grade III highly malignant oligodendrogliomas, grade IV Depending on the classification, the treatment options and survival time change.
- Benign oligodendrogliomas, grade I
- Low malignant oligodendrogliomas, grade II
- Anaplastic oligodendrogliomas, grade III
- Highly malignant oligodendrogliomas, grade IV
Symptoms
The symptoms of different brain tumors are usually relatively similar, since the symptoms are more dependent on the location of the tumor. The oligodendroglioma is mainly located in the front brain, this part of the brain is also called the frontal brain. If only a small tumor presses on the frontal brain, the symptoms can be very mild.
The symptoms in the initial stage usually include: headaches epileptic seizures nausea and vomiting In the initial stage, headaches are usually only present in the morning. They can also be accompanied by nausea and vomiting. These rather diffuse headaches often improve during the course of the day.
Epileptic seizures also occur very frequently in the initial stage, which is due to their location in the front part of the brain. Since the front part of the brain also contains the personality of a person, oligodendrogliomas in the late stage often lead to changes in character. These can include: increased aggressiveness drive disorder memory weakness neurological failures, such as speech disorders and paralysis are rare, but possible.
Usually, this only happens when the tumor has reached a certain size and begins to bleed in. When this happens, the symptoms appear suddenly and not slowly creeping in as if the tumor had only increased in size.
- Headaches
- Epileptic seizures
- Nausea and vomiting
- Increased aggressiveness
- Drive fault
- Weakness of memory
