Classification of brainstem gliomas by MRI appearance. Histopathology of a brainstem glioma. A brainstem glioma is a cancerous glioma tumor in the brainstem.Around 75% are diagnosed in children and young adults under the age of twenty, but have been known to affect older adults as well. [1]
The symptoms of brain stem tumors vary greatly and can include ataxia, cranial nerve palsy, headaches, problems with speech and swallowing, hearing loss, weakness, hemiparesis, vision abnormalities, ptosis, and behavioral changes. Another possible symptom is vomiting.
Their success-rate on cranial lesion is fairly effective, but recurrence is still a problem for severe patients. [6] One of the more exciting and promising routes for treatment involves stem cell use to combat astroblastoma. A study in 2005 profiled cell surface markers of astroblastoma cells removed from an 11-year-old patient.
The brain is susceptible to damage from conventional therapy. The brain has a limited capacity to repair itself. Many drugs cannot cross the blood–brain barrier to act on the tumor. Treatment of primary brain tumors consists of palliative (symptomatic) care and therapies intended to improve survival.
In PRES related to medications, there may be an interval of weeks to months between the initiation of the treatment and the development of PRES. [1] [3] After a hematopoietic stem cell transplantation (bone marrow transplant) the risk of PRES is approximately 8%, whereas the risk is lower (0.4-6%) after a solid organ transplant. [3]
A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are cancerous but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
The researchers discovered that people who had high fluctuations in their cholesterol levels had a 60 percent higher risk of developing dementia and a 23 percent greater risk of cognitive decline.
Central pontine myelinolysis is a neurological condition involving severe damage to the myelin sheath of nerve cells in the pons (an area of the brainstem). It is predominately iatrogenic (treatment-induced), and is characterized by acute paralysis, dysphagia (difficulty swallowing), dysarthria (difficulty speaking), and other neurological symptoms.
