Ocular abnormalities were present in 34.5% of microcephalic
infants examined, and involved the bilateral vision in 70% of them.
(24) It is known that the brain of microcephalic
patients is proportionally smaller, thus about 90% of the cases are associated with some degree of intellectual disability.
Dietary studies of sympatric species of Graptemys are limited to studies of female diets of two mesocephalic species and one microcephalic
species in the Mississippi River in Wisconsin by Vogt (1981), who simply noted a qualitative similarity in the diets of males of the three species; studies of two of the same species (one meso- and one microcephalic
) in a reservoir on the Tennessee River in western Kentucky (Lindeman, 1997, 2000b, 2013); and separate reports of the diets of syntopic microcephalic
and megacephalic species that was limited with regard to the sample size of the latter (Seigel and Brauman, 1994; Selman and Lindeman, 2015).
In Brazil, researchers say they are seeing a disproportionate number of microcephalic
infants with what appear to be severe deformities, many with four striking malformations at once: a large degree of brain tissue loss; unusually smooth, wrinkleless brains; many calcium deposits; and smaller cerebellums, which play a role in motor control, according to Dr.
These women receive little to no assistance from the Brazilian healthcare system, which is ill-equipped to deal with the sudden jump in the number of microcephalic
children and their need for intensive care.
The northeast is Brazil's poorest region, and many mothers arriving at urban public hospitals with cases of microcephalic
infants come from modest means in impoverished rural areas.
So far as we know, it doesn't kill anybody -- apart from some of the microcephalic
babies, about a quarter of whom die because their brains are too small to control their bodily functions.
One factor driving this over-diagnosis, as scientists working for the Brazilian institute that monitors birth defects noted in a recent report covered by Nature, is that the diagnostic criteria being used to identify microcephalic
babies in Brazil right now are very broad.
babies are moderately to severely mentally handicapped and will need a lifetime of care."
Additionally, she was microcephalic
. She had not any seizure on the day of PET/CT scanning.
