Can They Go A Week Without Noticing Cerebral Hemorrhage From An Injury
Possibly by MRIs: Mri technology has advanced dramatically in the last few years. Specialized sequences looking at the white fiber tracts or looking for signs of micro hemorrhages (t2-star sequences) are useful for detecting abnormalities. If the head injury is more severe clinically, there are usually more findings on mri. These may be followed over time with serial MRI scans to see if they hopefully improve. ...Read moreSee 1 more doctor answer
I have an Acquired Brain Injury caused by a colloid cyst in third ventricle, how do I source help or rehab for brain injury.
How many days after a fall and suffering a possible concussion are you at risk of complications,like brain bleed or swelling?
After someone has had a stroke or TIA can you tell from an MRI or CT scan? Also how long after one of these do post symptoms occur?
Yes and no: A definite stroke or cerebral infarction is visible on brain MRI right away as changes on the dwi sequence will be seen. A TIA can occur and by definition no true brain infarction occurs so in those studies will be normal. The diagnosis of TIA is based on history of a sudden neurologic event that completely resolves within 24 hours. Reversible ischemic neurologic deficit is another term. ...Read moreSee 2 more doctor answers
How long after an accident can brain trauma symptoms appear? My relative had brain trauma from a car accident several decades ago, and is now showing signs of mental impairment. Can these symptoms be attributed to the past brain trauma?
Evaluation needed: There is some increased risk of later dementia in individuals with traumatic brain injury, especially if it was severe - but cognitive declines can be caused by age, metabolic conditions, depression or other factors. New impairment warrants prompt neurological and neuropsychological assessment to assess the greater likelihood something recent is going on and figuring appropriate treatment. ...Read moreSee 2 more doctor answers
MRI software: Mri can detect presence of older blood products such as hemosiderin and fairly closely gauge timing of a bleed. Using a variety of imaging techniques such as perfusion/diffusion images, can pick up early stroke ischemia and follow developing stroke activity, and again timing can be estimated. ...Read moreSee 2 more doctor answers
Re: MRI brain - can a lesion be a scar from a previous stroke and if so how long would it take an infarction to become a scar / lesion? (lft occip)
SHORT TIME: The basic sequence is first localized inflammation of about 24-48 hrs maximally, and then localized cleanup from glia, macrophages, and microglia for about 4-6 wks., any recovery of myelin takes about 4 wks after healing starts, and maximal scarring occurs about 3-4 months. So if you did have a stroke, a focal MRI lesion shows the prior location. ...Read moreSee 1 more doctor answer
Is it okay to have your eyes dialated a month or 2 after a server concussion or will it cause concussion symptoms to come back?
I am showing symptoms of subarachnoid hemorrhage after a blow to the head. Is there any other "disease" i might be mistaking it for? See a doctor?
Is it ever that a life threatening brain injury occur without a direct blow to the head. For example, a car accident ?
Yes: Even if there is no impact, the rapid deceleration that occurs in a car accident can cause the brain to rapidly shift within the skull resulting in a shearing type injury, both to the brain, and to the blood vessels. ...Read more
Lacunar infarct: Some strokes seem clinically silent and may be imperceptible to a patient. Bleeding can occur at various sites in elderly patients with amyloid angiomatosis, and often the individual is completely unaware of the extent of the problem. Issue is the size of the hemorrhage, in terms of consequence, but if discerned, should always be treated in the most appropriate way. ...Read more

If facial droop was caused by a stroke could the droop come and go over a matter of hours or even minutes or would that point to an infectious cause?
I have a concussion and was in the car with someone who had to decelerate quickly from 60 to 10 mph by slamming on breaks. Could this hurt my brain??
Any concussion -: -is defined as loss of consciousness, & this does injure the brain, but it usually recovers. But repeated such injuries is of concern. If you were not unconscious & are doing well,you should be OK. Sometimes there's a thing called post concussive syndrome where head aches are common, but it is usually after a severe blow to the head. ...Read more
Can you get a concussion from semi-sudden deacceleration? (ie. sprinting then abruptly stopping on a dime). Or would it take more force like carcrash?
Can you bruise an artery, for example can a bruise be caused by a leakage from an artery if so does it heal like any other bruise?
Skin?: If you are referring to visible bruising in the skin it is not usually arterial bleeding. Rather it is localized small veins and capillaries. Deeper muscle injury can involve smaller arterioles which quickly retract and stop bleeding. All else being normal bruises are reabsorbed over time and resolve. ...Read more
