The temporal lobe is temporarily needed when consolidating new information; as the learning becomes stronger, the neocortex becomes more independent of the temporal lobe.Studies on specific cases demonstrate how particular impaired areas of the hippocampus are associated with the severity of RA. Damage can be limited to the CA1 field of the hippocampus, causing very limited RA for about one to two years. More extensive damage limited to the hippocampus causes temporally graded amnesia for 15 to 25 years. Another study suggests that large medial temporal lobe lesions, that extend laterally to include other regions, produce more extensive RA, covering 40 to 50 years. These findings suggest that density of RA becomes more severe and long-term as the damage extends beyond the hippocampus to surrounding structures. The common studied causes of RA do not always lead to the onset of RA. It may even be that in some cases both conscious feigning and unconscious processes are at play. Traumatic brain injury (TBI) or post-traumatic amnesia
Traumatic brain injury (TBI), also known as post-traumatic amnesia, occurs from an external force that causes structural damage to the brain, such as a sharp blow to the head, a diffuse axonal injury, or childhood brain damage (e.g., shaken baby syndrome). In cases of sudden rapid acceleration, the brain continues moving around in the skull, harming brain tissue as it hits internal protrusions.TBI varies according to impact of external forces, location of structural damage, and severity of damage ranging from mild to severe.
Biphenotypic acute leukaemia (BAL) is an uncommon type of leukemia which arises in multipotent progenitor cells which have the ability to differentiate into both myeloid and lymphoid lineages. It is a subtype of "leukemia of ambiguous lineage".The direct reasons leading to BAL are still not clear. BAL can be de novo or secondary to previous cytotoxic therapy. Many factors, such viruses, hereditary factors, and radiation, might have a relationship with BAL. BAL is hard to treat. Usually the chemotherapy is chosen according to the morphology of the blast (ALL or AML). A blood-forming stem-cell transplantation is highly recommended. About 5% of acute leukaemia cases are BAL. BAL can occur in all ages of people but occurs more in adults than in children. Signs and symptoms
BAL has similar symptoms to other types of leukemia, but they are usually more serious. Symptoms caused by bone marrow damage
Bruising, spotting: the reason is lack of platelets. it is very common in BAL patients, most of patients die due to the
A low level of red blood cells in the bloodstream: Because the decline of hematopoietic function, need blood transfusion therapy
Persistent fever, infection prolonged healing:
Diffuse hemorrhage: which is dangerous and might lead to death. Symptoms caused by blood cancer cells infiltration into tissues:
Swollen lymph nodes
Joint pain
Swelling of the gums
Enlargement of the liver and spleen
Headache and vomiting: blood cancer infiltration into the wear performance of the central nervous system. Skin lumps: Because look was slightly green, also known as the "Green tumor."
