Link between fetal doppler use and PMG??

[Guest guest]

Has anyone read anything about a potential link between abnormal brain

development and the use of ultrasound in pregnancy?

My son, Harry is now 18 months old and has bilateral, generalised PMG. We've

had a couple of genetic tests done but they came back negative. There's also no

history of this in either of our families that we know of. I had 4 scans (two

on the NHS in UK and two private ones) and I also bought one of those fetal

dopplers which I did use quite a lot early on in my pregnancy. I do wonder

whether the radio waves somehow disturbed the developing brain cells at a

crucial time????

Would be interested to know what sort of exposure other PMG mum's had to

ultrasound in pregnancy and if you've also had a normal, healthy child if there

was any difference in the two pregnancies.

This is an extract from an article I found on the New Scientist website:

" The new research involved using a chemical to trace brain cells in growing

mouse embryos. The researchers exposed the embryos to ultrasound shortly

afterwards, late in the third week of gestation, a crucial period for mice in

which brain cells become organised.

Dissections following the birth of the mice showed that a small percentage of

brain cells had not migrated to their normal place. For example, 6% of the

chemically tagged brain cells had not migrated normally in mice exposed to two

30-minute ultrasound sessions.

It may be that the ultrasound waves somehow disrupt the connections formed

between cells as they move into their proper location, suggests Pasko Rakic at

Yale Medical School in New Haven, Connecticut, US, who carried out the research

with colleagues. "
