Will increasing bdnf levels prevent autism in children?

Will increasing bdnf levels prevent autism in children?

Unusually high level: of the signaling peptide BDNF (brain-derived neurotrophic factor) have been detected in children w/ autism. BDNF regulates birth and differentiation of brain cells (neurons). Barbara Hempstead et al (Weill Medical College, Cornell Univ) propose that BDNF may be over-expressed in the brains of these children, causing neurological defects that lead to the disorder but causation not yet proven. ...Read more

Missed Developmental Milestones (Definition)

We expect babies and children to be able to do certain things by certain ages. We know not every child is the same, and also have to take into account things like prematurity. For instance, most babies are pulling up on furniture and attempting to take a first step around their first birthday. If they get to 15-16 months and aren't doing it, we say that's a delayed ...Read more

Age 21, IQ level below 70, in medical test result is iq level 67% and mild mental retardation. please suggest the further treatment for increase IQ LA?

Not available: IQ tests were developed initially to predict schooling success in individual students. It is a measuring tool like a yard stick. There is no treatment to change an IQ just like there is no way to change an adults height. You are what you are by this measurement. It does not measure many talents that can lead to success in arts or entertainment. It does not say you should not try. ...Read more

Why is elevated B12 serum found in autistic children?

Why is elevated B12 serum found in autistic children?

Not always seen: More often i will see low or normal levels of B12 unless there is supplementation. This vitamin has a fairly complicated absorption process and is not efficient in some. If there is gut inflammation or infection or if there is an autoimmune process oral intake is not effective and you have to move to sublingual or injections. B12 works closely with folate (folic acid) and b6 and very often all need to be used. ...Read more

Our six-month old son has high calcium and high phosphorus levels but normal pth? The pediatrician can't explain. Any ideas?

Look further: How high? Phos is often high in babies because blood can hemolyze if squeezed out. Ionized calcium? Albumin? Vitamin d panel? Alk phos? Repeat labs including the above. Any significant calcium or phosphorus in urine? Kidney function? May need a pediatric endocrinologist. ...Read more

Is there any study that linked high levels of testosterone to a low i.Q. Or lower intelligence?

Is there any study that linked high levels of testosterone to a low i.Q. Or lower intelligence?

Correlations with IQ: If you look hard enough, you can probably find a study that will show a correlation between anything. That proves nothing. The normal range of t in men is approx 300-1000 (depending on the assay). Among normal men (i.e. No extra chromosomes, not autistic, etc), there is no relationship between t and iq. ...Read more

During what blood levels does lead start to cause cognitive impairment in adults?

During what blood levels does lead start to cause cognitive impairment in adults?

A-hi10ug/dl,C-5ug/dl: Elevated lead in the body can be detected by the presence of changes in blood cells visible with a microscope and dense lines in the bones of children on X-ray, main tool for dx. is the blood lead level. When blood lead levels are recorded, the results indicate lead is circulating within the blood stream, not the amt. being stored in the body.[2] Elevated lead in the body can be detected by the presence of changes in blood cells visible with a microscope and dense lines in the bones of children seen on X-ray, but the main tool for diagnosis is measurement of the blood lead level. When blood lead levels are recorded, the results indicate how much lead is circulating within the blood stream, not the amount being stored in the body.[2] There are two units for reporting blood lead level, either micrograms per deciliter (µg/dl), or micrograms per 100 grams (µg/100 g) of whole blood, which are numerically equivalent. The Centers for Disease Control (US) has set the standard elevated blood lead level for adults to be 10 (µg/dl) of the whole blood. For children the number is set much lower at 5 (µg/dl) of blood as of 2012[3] down from a previous 10 (µg/dl).[4] Children are especially prone to the health effects of lead and, as a result, blood lead levels must be set lower and closely monitored if contamination is possible.[2] The major treatments are removal of the source of lead and chelation therapy (administration of agents that bind lead so it can be excreted). ...Read more

Many studies say that HGH upregulates IGF-1. Intermittent fasting (8hour feeding window) boosts GH-levels. Why than is IF associated with LOWER IGF-1?

Many studies say that HGH upregulates IGF-1. Intermittent fasting (8hour feeding window) boosts GH-levels. Why than is IF associated with LOWER IGF-1?

Not so simple: The regulation of IGF1 is more complex than just GH levels. Diet/weight loss and inadequate nutrition is well known to lower IGF1. GH levels spike in the AM, but with age GH levels are low, and there is not much you can do to elevate them. Exercise, stress reduction, weight maintenance are all good, but not necessarily related to GH. ...Read more

In light of recent scientific findings of high folic acid levels possibly linked to autism, please explain what are 'high levels?"

Newer observational: data: per Johns Hopkins University, Baltimore, MD, maternal plasma folate (folic acid) (vitamin B9) concentrations >59 nmol/L & vitamin B12 concentrations >600 pmol/L, respectively, the incidence of autism ?es more than 17-fold.

Hello - what are normal iron levels in a child. My daughter is 7 and recent Dr. Visit has shown very high iron level. We are meeting a hematologist.

Iron levels.: 7–140 ng/mL or 7–140 mcg/L. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. ...Read more

Post-prandial gluc levels always ~85-110. Wake up gluc level can be as high as 110. Which test is more significant? Likelihood I'm pre-diabetic?

Post-prandial gluc levels always ~85-110.  Wake up gluc level can be as high as 110.  Which test is more significant?  Likelihood I'm pre-diabetic?

Wrong Testing: Not sure why you are spending the money it takes to do blood sugar testing when you have no diabetes diagnosis. These numbers are not the way diabetes is diagnosed. Especially when they are near normal. A true diabetes or pre-deiabetes test requires a formal Hemoglobin A1C test. It is a felony to use testing prescription equipment not paid for by your insurance company. Just saying. ...Read more

Possible for labs to measure LDH units differently? Child inexplicably ill for months w/normal CBC. LDH in the 600-700s. Dr: "not significantly high."

Possible for labs to measure LDH units differently? Child inexplicably ill for months w/normal CBC. LDH in the 600-700s. Dr: "not significantly high."

Non-specific marker: The LDH test is a non specific marker of inflammation in the body.The enzyme originates from several defined sites, including liver, blood, lungs, kidneys, muscle, etc and a further test could define which area is involved. If your kid has had a vague flu like illness with muscle pains, this may be within the expected findings of the doc. A followup test should show recovery ...Read more

Is a single mutation mthfr common in children with autism?   If homocysteine levels are normal, should I be concerned?,

More research needed: The mutation mthfr has been implicated in a variety of psi strip illnesses from schizophrenia to down's syndrome. Homocysteine levels san be normal in autism. At this juncture no one has been able to find the cause of autism much more research is needed.Take mthfr with a grain of salt. There is absolutely no evidence that it can cause autism. ...Read more
