Albert Ko, an epidemiologist and infectious disease expert at Yale University, said babies born without the condition could suffer other neurological complications that are not necessarily as obvious.
He told the Washington Post that other brain related abnormalities had been linked to the Zika virus outbreak without firm evidence, but that he believes the disease is the probable cause of most.
He said researchers investigating cases of microcephaly in maternity hospitals in Salvador, Brazil, are seeing a “spectrum” of birth defects.
“Many have fairly severe central nervous system lesions," he said.
"There are also a lot of calcium deposits. Those can cause seizures and cause impairment in terms of function for the brain.”
Dr Ko also said some of the babies brains are smooth, when they would normally have wrinkles, which suggests they have not developed fully.
A number of newborns also have visual and hearing impairments, he added.
“It seems like microcephaly may just be the tip of the iceberg,” warned Dr Ko.
“The preliminary evidence is that [some] babies who don’t have microcephaly may also have neurological lesions or birth defects that are not as obvious as microcephaly.”
Speaking about how the virus is affecting pregnant women and families, Dr Ko said: “Obviously there’s a large amount of fear, especially among pregnant women.
“For many people, the level of anxiety is extremely great. People want a birth. It’s one of the greatest pleasures or expressions of love in a person’s life.
“For many of the families, it really hasn’t hit yet what the future is going to be.“
However, he offered a little hope, saying: “Not all the brains are severely compromised. Some of the babies, now one month or two months old, they’re feeding, they’re growing.”
