Brain Aneysurum Take To Develop
Depends: Temporary brain dysfunction from the first dose lasting at least 24 hours. No clear cut permanent damage at any exposure although it may take weeks to recover normal function after daily use. ...Read more
It depends: Brain damage does not occur unless there is a significant loss of oxygen and/or other vital nutrients to the brain. Cessation of breathing (apnea) per se does not cause brain damage unless the oxygen level in the blood falls to dangerously low levels for a prolonged period of time. Even if apneic, oxygen levels can be sustained in the blood through other means, for many minutes, or even hours. ...Read moreSee 1 more doctor answer
2 yrs after college: Most physicians assistant programs are 2 year degrees after completing a bachelors degree. However, to get into a pa program they will want you to have experience in a medical setting so this can add time to your path. ...Read more
Can overdrainage/suction of CSF through a lumbar drain cause brain damage, paralysis/death? How much fluid would it take for this damage to occur?
Yes but this is : Variable based on age/size of person as well as underlying medical issues/condition as well as the rate of drainage as CSF is constantly restored. ...Read more
4 minutes or more: In the event of a full blown cardiac arrest there can be brain damage in as little as 4 to 5 minutes without circulation at normal body temperature. If the body had been cooled by submersion in cold water it could be much longer. Less severe lack of oxygen will take longer to produce brain damage. ...Read more
Impossible to answer: There are so many variables i doubt that any of us here can give you specific reliable information. Brain swelling is serious, of course. What prompts the question? Perhaps you can be more specific in why you are asking this. ...Read more
Injury starts @ 4min: The exact speed of brain cell injury depends on a variety of factors including blood flow, oxygen supply, body temperature, blood glucose etc.Injury to cells is expected after 4 minutes without oxygen as the blood oxygen content drops to critical levels. Part of brain function might recover if oxygen was suddenly available, but as time passed the point of no return would be reached. ...Read more
Can you tell me, are more people surviving gunshot wounds to the head these days, or is it just media proliferation?
Gunshot wounds: To the head and "survivability" have advanced very slowly with the advancement of surgical technique, pre-hospital care, emergency department care and the technology of life support (a topic too broad to break into it's parts). However, keep in mind that gunshot wounds to the head still create the same damage they did 50 years ago and that damage can't yet be mitigated unfortunately. ...Read more
Unknown: There is no good answer to this question because we have only limited data on exactly how, when and why brain aneurysms develop. Once an aneurysm is identified, if it is non-ruptured and small (<5mm in size), we often follow these with yearly tests to see if the aneurysm is enlarging. In these cases, they tend to grow at varying rates or not grow in size at all. ...Read more
Actually`: Some believe that it takes only the time for a SINGLE CELL which has MUTATED (or produced by an abnormal strand of RNA/DNA to START tumor formation. As to how long it takes for SYMPTOMS to occur THAT depends upon the LOCATION of the TUMOR and whether it IRRITATES surrounding tissue ("produces" a siezure) Hope this helps! Dr Z ...Read more
Can someone tell me how long will it take for a cocaine user to show brain and nose tissue damage?
Many variables: Injury to the nasal passages from 'snorthing' will depend on frequency of use, with what the Cocaine was cut and the health of the tissue in the nose. The irritation and erosion is visible. The brain effect is not visible and totally unpredictable. Amount and time of exposure are the critical factors that turn off the brain factory that makes dopamine. Once closed we do not know how to restart. ...Read more
Radiosurgery, either: Linac or gamma knife, is not commonly used for glioma, but is regularly used for metastatic lesions. The procedure usually takes a day, including frame fixing, mr to identify lesion(s), and tehn treatment delivery. But you walk out of the suite and go home. May feel some fatigue, head ache, nausea. No aftermath is common. ...Read more
Depends.: Some tumors are very aggressive and have a life expectancy of less than 9 months. Some are slower to grow. Early detection helps out for better treatment. Most people have some type of neurological symptoms that hints doctors to look for them. ...Read more
I heard that sleep deprivation can kill brain cells. How long does it actually takes till your brain cells start dying? (In 18yrs old person)
Research still out: Research has been done on mice and it's likely that it's also true for us - for them 3 days was enough for some cell death. That might be different in people but whatever, it's not a good thing. Brain cells die when we sneeze or do other such things but we have so very many! So, don't worry (that's not healthy) but do sleep regularly and enough! ...Read more
In your experience how long will it take an untreated pneumothorax to become life changing or fatal?
Depends: The issue is not that simple.Some people, like asthmatics, can develop a small pneumothorax associated with a cough, that may go unnoticed and resolve over time with minimal intervention.Some that develop one after trauma, need immediate help or their circulatory system may become impaired and lead to shock within the hour. ...Read more
Whats the immediate precaution we can take if ebola virus detected? Mention medical tests which we will have to take?
A/w Dr. Lindquist: Per the CDC, Ebola can be tested w/i a few days after sx's begin w: ELISA (antigen-capture enzyme-linked immunoabsorbent assay), IgM ELISA, PCR (Polymerase chain reaction) & isolation of the virus. Later in course of disease can be tested by looking for IgM & IgG antibioties. See: http://www.cdc.gov/vhf/ebola/diagnosis/ ** Isolation & hospitalzation are needed if acutely ill due to Ebola. ...Read moreSee 1 more doctor answer
