Brain Damage (Definition)

Anything that disrupts tissue integrity can cause brain damage: lack of or reduced oxygen (stroke), viamin deficiency, pressure (hydrocephalus, or, bleeding or tumor inside the skull), blunt or penetrating trauma; infection; inflammation (immune system mediated or otherwise); toxins (alcohol, ecstasy, lead, mercury, arsenic, to name but a few); diseases (ms, diabetes, ...Read more

Please tell me, could a baby survive with serious brain damage due to no oxygen for 20 minutes at birth?

Please tell me, could a baby survive with serious brain damage due to no oxygen for 20 minutes at birth?

Yes: Severe anoxia causing brain injury and server handicap may not result in early infant death. Children with severe brain injury whether acquired late in pregnancy, even within days of the onset of labor, or less likely during labor may live for decades requiring a great deal of special care and services. ...Read more

How many minutes without oxygen does it take before a child suffers permanent brain damage?

How many minutes without oxygen does it take before a child suffers permanent brain damage?

Does oxygen desaturation on a long-haul flight (13.5 hours) cause any sort of brain damage to a baby? I've read they go as low as 80% and lower.

Does oxygen desaturation on a long-haul flight (13.5 hours)  cause any sort of brain damage to a baby?  I've read they go as low as 80% and lower.

Odd comment: Babies with a normal lung structure will maintain normal oxygen levels on a long flight the same way any adult or older child would. There is no drop in the blood oxygen level during a flight. Pressurized air craft are a safe mode of travel for infants. Someone is providing you with goofy information. ...Read more

My niece was without oxygen for about 5 minutes was brought back but is now comatose for 13 days now she has brain damage and had EEG had 7 seizures?

My niece was without oxygen for about 5 minutes was brought back but is now comatose for 13 days now she has brain damage  and had EEG had 7 seizures?

Hypoxic encephal.: The hypoxia has likely resulted a secondary brain injury, and depending on age, the extent of recovery will be unknown for some time. The seizures are not unexpected and will need control, but likely not to be a long-term challenge. Have a neurology consult, provide supportive care, and hope for the best. ...Read more

My sister went with oxygen for 7 minutes and a heart attack she a diabetic and had very low blood pressure kidney damage will she have brain damage?

My sister went with oxygen for 7 minutes and a heart attack she a diabetic and had very low blood pressure kidney damage will she have brain damage?

Not sure: Adults who are deprived of oxygen due to cardiac arrest for over 5 minutes usually suffer brain damage. However since she did not have a cardiac arrest and,despite very low blood pressure, she may have had enough cerebral circulation to avoid significant brain damage. However because of diabetes and smoking history, she may have come vascular disease which increases her risk. Hope for the best. ...Read more

Below what level blood oxygen does brain damage happen?

Below what level blood oxygen does brain damage happen?

Hypoxia: That depends on many factors: age of the person when it happened (children tolerate low oxygen better than adults), duration of the low oxygen (longer is worse), how healthy the person is (medical conditions may make the person more sensitive), and the body temperature of the person when it happened (the colder they were, the less oxygen their body and brain needed). There's no simple answer. ...Read more

Can you get brain damage from lack of oxygen fainting?

Can you get brain damage from lack of oxygen fainting?

Generally no: A simple faint restores adequate blood flow to the brain as you become horizontal, and recovery is forthcoming. If you have brain damage from a faint it can be from a near- fatal arrhythmia (such as from long qt syndrome or hypertrophic cardiomyopathy.), or prolonged seizure. A physician can help determine if there is cause for concern. ...Read more

Can you get brain damage from lack of oxygen from snoring?

Can you get brain damage from lack of oxygen from snoring?

2 different events: Snoring results from vibration emitted from the upper airways, for instance a sides of the nostrils moving toward the septum during inhalation or more likely from vibration of the soft palate, uvula & perhaps tongue. Snoring is a noise. Its cause is airway obstruction. Severe obstruction blocks oxygen getting into the lung, hence possible brain injury--consider having polysomnogram test. ...Read more
