I am very interested in medicine and think this question is a very good one since they said that it is very rare and the Hospital did not have a case like Brooke before !

I have found another report on a little Girl named Ashley who will which was reported on guardian,uk,co
Although she has a normal life expectancy, she will, physically, always be nine years old. Her growth has been suspended at 4ft 5in (1.3 metres), rather than the 5ft 6in she would probably otherwise have become. Her weight will stick at around 75lb (34kg) rather than 125lb.

I have read up on a couple of syndromes and think these 2 are very likely to be close to what she might have ( not saying it is ) but kids who are diagnosed with these syndromes have often growth retardation and seem to be " froezen in time "

Wolf-Hirschhorn syndrome
The most common abnormalities seen include severe to profound mental retardation, microcephaly (small head), seizures, poor muscle tone, and cleft lip and/or cleft palate. Characteristic facial features, include strabismus, hypertelorism, down-turned "fishlike" mouth, short upper lip and philtrum, small chin, ear tags or pits, and cranial asymmetry. Occasional abnormalities include heart defects, hypospadias, scoliosis, ptosis, fused teeth, hearing loss, delayed bone age, low hairline with webbed neck, and renal anomalies.

This Ashkenazi Jewish Panel detects mutations associated with the following eight disorders that commonly occur in Ashkenazi-Jewish (Eastern European Jewish) individuals:

Bloom syndrome:( one out of 8 )
Children with Bloom syndrome are affected with growth retardation, abnormalities in skin pigmentation, immunodeficiency, a predisposition to cancer, and chromosomal instability. Death usually occurs in the teens or twenties, most often caused by cancer.

I am very amazed by parents who have children who are sick and still manage to give them a life full of happiness and dont neglect their other children as well - some people who have sick children give them up or dont take care of them.
The Parents of Brooke must be very strong and I wish them all the best for their future as well as for their childrens future.

No, I have never heard of another case like Brooke's. I think she suffers from reverse dog years. It would be really cool, she would outlive most of us.

The thing that really intrigue me was that she had a brain tumor and then the next day she didn't. I believe the secret to eternal life might be in our brian somehow.
