Question

How do arteriovenous malformations damage the brain and spinal cord?

Answer 1

Often none: Unless it leaks, there would be no symptoms in most cases. Leaking can cause intense headache or stroke-like symptoms such as focal weakness, loss of speech or vision. Avm discovered after a minor stroke can be corrected before a major stroke. Family history of avm may prompt investigation in someone with no symptoms.

Answer 2

Congenital: An avm is a congenital malformation of brain and possibly spinal blood vessels. They predispose those that have them to neurologic symptoms and, potentially, bleeding. A thorough neurosurgical evaluation is essentially if an avm is suspected.

Answer 3

Localized deficits: A brain AVM is a connection of arteries directly to veins, without going through capilaries. When the flow increases it can produce a 'steal' effect by taking blood from surrounding tissue, resulting in an abnormality of brain fuction controled by the area of the 'steal'. another manifestation is a result of bleeding of the aVM

Answer 4

No: The typical fevers of childhood illnesses do not cause brain trauma and damage. If the fever is caused by an infection of the brain (meningitis or encephalitis), the infection can cause damage but not the fever. Fevers from heat stroke (in the 107 degree range or more) may cause brain damage but these are not typical fevers of childhood. They result from exposure to extreme heat.

Answer 5

No: No only at very high levels, above 105 degrees, and for prolonged periods of time. Think babies being left in a car on a 90 degree day type scenario. The fevers typical obtained through infection and inflammation (100-104) are not going to cause brain damage or trauma.

Answer 6

No: Fever is part of the immune system, and helps your child fight off infection. Children tolerate even high fevers very well. There is no damage to your child from the fever itself. Fever is a sign that there is illness, so your doctor will evaluate to find out what is causing the fever.

Answer 7

No: A healthy child who gets fever will not get brain damage from the fever. If a child gets a severe illness, such as an infection in the brain, the child may develop brain damage, but that damage was not caused by the fever. Fever is a sign that tells parents to observe the child, and then contact a doctor if any unusual symptoms begin; or contact a doctor right away if the child is <3 months old.

Answer 8

No: Rarely is this is a sign of a serious problem. Many children bang their heads as a way of "self soothing." the best approach is to make sure they are in a safe environment where they cannot hurt themselves and to try to distract the from the behavior. If worsening behavior or other symptoms develop, speak with your pediatrician about this.

Answer 9

HeadBanging maybe ok: Head banging is ok if it happens once in a while, if a baby is otherwise normally developing, and the baby outgrows it and doesn't do it later. Babies like to interact with their environment, which includes hitting things with the hands, kicking things with the feet, and banging things with the head. However, in a baby who behaves oddly in any other way, headbanging may be a serious problem.

Answer 10

Generally No: If your baby is otherwise healthy and developing normally, headbanging is either a " pacifier" mechanism or an expression of anger, a temper tantrum. In either case, it is best ignored. With an otherwise normal child, it is almost never a sign of of a brain condition. Also children who bang their heads do not cause any serious injury other than an occasional bruise.

Answer 11

Usually not: Most children will bang their head to get attention. Usually, this is not significant for anything in particular.

Answer 12

CP acquired< 3yo: By definition cerebral palsy is related to injury to the developing nervous system befort the 3rd birthday. (pregnancy, labor, delivery or the infancy years). Brain injury after that point is looked on as a different process similar to adult strokes or brain injury defects. The separation is more than random. Infants with CP have a greater recovery potential than adults with similar injuries.

Answer 13

Acquired form: The more common form of cerebral palsy is the congenital form that is present from birth and is usually associated with defects of the brain or injury to the developing brain. Later injuries including strokes and trauma may cause severe motor problems that can then be classified as a form of acquired cerebral palsy. It then is just a matter of terminology: static encephalopathy affecting motor.

Answer 14

No: Cerebral palsy is due to a brain injury sustained before age two. The brain injury is stable, but the manifestations of the injury can change. Once you have been diagnosed with cp, you always have it. Adults can be diagnosed with a CP only if it was missed as a child.

Answer 15

See an expert: A surgical resident i know had a chiari malformation - went to a specialist - had it repaired and now works 80 hours/week with no disability. Obviously, these malformations vary from person to person, but make sure that you are seen by an expert. He was misdiagnosed and almost gave up his dream of a surgical career.

Answer 16

Part of the team: Brain tumors are either benign or malignant and are either primary or due to tumors elsewhere in the body. Any patient with brain tumor needs a team support. There may be a surgeon, cancer specialist, neurologist, radiation specialist, chemotherapy team, rehab therapists, psychological support, etc. You can help by being part of the team. Alcohol in small amounts should not harm but no smoking.

Answer 17

Variable but bad: Your questions are broad. There are benign brain tumors and malignant ones; the effects of alcohol or nicotine may depend on tumor type, and also on how much alcohol or how much nicotine. Likely drinking more than minimal alcohol isn't a good idea if you have a brain tumor, and smoking is never a good idea. Care for someone with a brain tumor also varies. Try support groups such as from abta.
