  • Paresthesias: patients often present with (hemiparesis), or weakness on only one side of the body, which is often a result of damage to neighboring brain tissue. (wikipedia.org)
  • malignant brain
  • In these cases, untreated survival usually amounts to only a few months, and survival with current radiation and chemotherapy treatments may extend that time from around a year to a year and a half, possibly two or more, depending on the patient's condition, immune function, treatments used, and the specific type of malignant brain neoplasm.

  • Evaluation
  • As one evaluation of brain. (springer.com)

(springer.com)
  • focal
  • Charcot-Wilbrand syndrome (CWS) describes dream loss following focal brain damage specifically characterized by visual agnosia and loss of ability to mentally recall or "revisualize" images. (wikipedia.org)
  • impairment
  • Earlier, in 1908, researchers Lewandowsky and Stadelmann published the first report of an individual afflicted with calculation impairment due to brain damage. (wikipedia.org)
  • migraine
  • The first possibility is that migraine offers an advantage to the organism in fighting infection by increasing blood flow to the brain. (wikipedia.org)
  • However
  • The question remains, however, as to the extent of GI in other samples of Ph tumors and, indeed, in different types of Drosophila malignant neoplasms. (g3journal.org)
  • However due to significant differences in the observations of Charcot and Wilbrand's case work, this syndrome bridged the entire loss of dreaming, whether it be due to the isolated inability of the brain to produce images while asleep as Charcot had dictated, or the complete loss of dreaming all together as with Wilbrand. (wikipedia.org)
  • However, damage to various but not necessarily identified areas of the brain can cause computational difficulties, as various cognitive functions are necessary to execute mathematical calculations. (wikipedia.org)
  • Treatment
  • Treatment for a brain tumor is dependent on multiple factors, including the location and size of the tumor. (wisegeek.com)
  • high-grade
  • The rapid growth of fast-growing high-grade brain tumors may damage the subcortical network essential for electrical transmission, whereas slow-growing tumors have been suggested to induce partial deafferentation of cortical regions, causing denervation hypersensitivity and producing an epileptogenic milieu. (wikipedia.org)
  • In general, when brain lesions are smaller than Grade I, demarcating between these features is near impossible, often mistaking astroblastoma with glial neoplasms, high-grade astrocytes, and embryonal neoplasms. (wikipedia.org)
  • include
  • Relevant molecular changes in brain tumors that affect BBB structure and function include decreased expression of transmembrane junctional proteins and heightened release of vascular endothelial growth factor. (wikipedia.org)
  • nerve
  • Acoustic neuroma is a rare, non-malignant tumor that develops on the main nerve leading from the inner ear to the brain. (avaate.org)
  • Olfactory-induced migraines (migraines stimulated by strong smells) have been explained as an attempt to interrupt the entry of toxins into the brain via the olfactory nerve. (wikipedia.org)
  • condition
  • This condition is quite rare affecting only a select number of brain damage patients, and further study could help illustrate the neurological pathway for dream formation. (wikipedia.org)
  • present
  • T is will allow cross-referencing to pr- molecules in the brain to the present time, dif usion lematic cases which one may encounter. (springer.com)
  • Adrenal
  • Domestic rats differ from wild rats in many ways: they are calmer and significantly less likely to bite, they can tolerate greater crowding, they breed earlier and produce more offspring, and their brains, livers, kidneys, adrenal glands, and hearts are smaller. (wikipedia.org)
  • cancers
  • Although this association can be accidental, it emphasizes the fact that patients with a history of a neoplasm should be monitored regularly in order to diagnose and treat possible second primary cancers in a timely manner. (biomedcentral.com)
  • Of note, this consideration is of great importance in patients whose first neoplasms have better prognosis and survival rates, which provide them more time to develop second primary cancers, for example, pituitary adenoma. (biomedcentral.com)
  • cancer
  • According to National Cancer Registry, there were 4 incidences and 4 deaths due to malignant neoplasms in Taiwan during the period 2000-2009. (cogemonews.com)

  • Primary central nervous system (CNS) solitary fibrous tumour/hemangiopericytoma (SFT/HPC) is a rare neoplasm and its classification criteria have been redefined by the latest WHO Classification of CNS Tumours. (readbyqxmd.com)
  • Craniopharyngioma is a rare, usually suprasellar neoplasm, which may be cystic, that develops from nests of epithelium derived from Rathke's pouch. (wikipedia.org)
  • midbrain
  • The most common site for cerebellar lesions that lead to intention tremors has been reported to be the superior cerebellar peduncle, through which all fibers carrying information to the midbrain pass, and the dentate nucleus, which is also responsible for linking the cerebellum to the rest of the brain. (wikipedia.org)
  • Multiple
  • At the other end of this spectrum, detection of the myeloid protein indicates the presence of a hematological malignancy, i.e. multiple myeloma, Waldenström's macroglobulinemia, or other B cell-associated neoplasm, that derives stepwise from its MGUS precursors. (wikipedia.org)
  • children
  • The incidence rate for neoplasms was highest among children either after IVF (1.5/1000) and somewhat lower for OI births (1.0/1000) as compared to that of naturally conceived children (.59/1000). (neurosciencenews.com)
  • normal
  • Intention tremors that are caused by normal, everyday activities, such as stress, anxiety, fear, anger, caffeine, and fatigue do not seem to result from damage to any part of the brain. (wikipedia.org)
  • blood
  • In some hospitals, a perfusion CT scan may be done to see where the blood is flowing and not flowing in your brain. (wikipedia.org)
