Perinatal issues: FGR, LBW, SGA, PTB

Post Reply New Topic

FGR - fetal growth restriction,
LBW - low birth weight (<2500 g),
SGA - small for gestational age,
PTB - pre-term birth.

I am a male. I had FGR, LBW and almost certainly SGA. I had birth weight 2150 g, was born on time (possibly about 38th - 39th week of gestation), had body length 53 cm (according to Polish method of measuring newborns, using WHO method birth weight probably would be about 5 cm smaller), had head circumference 32 cm and chest circumference 28 cm, had the largest drop of body weight after birth to 2120 g (very small, only nearly 1,5%), had 10 Apgar points and I came to my home in 33rd day after my birth. My chest circumference was about 4 cm smaller than my head circumference, which means serious asymmetric FGR, especially combined with low birth weight despite being born on time.

I was diagnosed with Asperger syndrome in 2008 according to ICD-10, I was also diagnosed with OCD when I was about 17 years old. In 2015 I was diagnosed with schizotypal disorder in addition to Asperger syndrome and OCD. I may have ADHD-C according to DIVA-5 test from September 2024 made by a psychologist which lasted about two hours. I suppose that I have cognitive disengagement syndrome. I suppose that I have NVLD/DVSD because I had large VIQ-PIQ split in Wechsler test in 2016 (VIQ 126, PIQ 104, FSIQ 117), had poor results in Benton test for visual memory (I made four errors while the norm would be zero or one error) also in 2016. I have poor mental visualization abilities, especially in precise skills and 3D. I think mostly in words, abstracts, in logical, conceptual, intuitive way. I have no aphantasia, though.

I have none.
My younger sister has at least 3 of them.

I was the healthier kid.
She was the sickly kid.

I'm autistic.
She's NT.

Didn't matter.

My sister had at least 3 of them. She has high-functioning learning difficulties and better ability to make friends than me.

I had none of those yet my brain is f****d up.

@Edna3362, @Tamaya - I could be shocked by what you wrote - you both had better prenatal growth and you have autism and you wrote about siblings who had three (or more) of them and are NT/not-autistic, it is very surprising

I had the poorest intrauterinal growth from three sibling and I am the most autistic of the children of my parents, my sister who was "between" me and my brother can be autistic too and in some skills she can be more affected than me (sound sensitivity, worse school performance in adulthood, worse handwriting, probably she learned to ride a bite somewhat later than me) and our brother is NT and he functions well.

the extended birthing with complications, asfar as i have seen, can give the disabled autistic symptoms
Birth Asphyxia (https://www.ncbi.nlm.nih.gov/books/NBK430782/)
Perinatal asphyxia occurs when blood flow or gas exchange to or from the fetus is disrupted immediately before, during, or after birth. This condition can lead to severe systemic and neurological complications due to reduced oxygen and blood supply to vital organs, including the brain, heart, liver, and muscles. When placental (prenatal) or pulmonary (postnatal) gas exchange is compromised, oxygen deprivation occurs, causing progressive hypoxemia and hypercapnia. If severe, this oxygen deficit triggers anaerobic metabolism and lactic acidosis. Neonatal hypoxic-ischemic encephalopathy (HIE) specifically refers to the neurological damage resulting from perinatal asphyxia and ischemia.

None of those. And labor was kinda short for a first time mom. I also slept very well, even as a newborn.

BiL (not ASD) suffered asphyxiation at birth but turned out fine.
