Zika ‘can cause’ havoc in brains

The zika virus can “wreak havoc” in the brains of adults, causing long-term damage that may mirror the effects of Alzheimer’s disease, new research suggests.

The mosquito-borne infection has already been linked to microcephaly — a serious birth defect in which babies are born with small heads and brain damage.

Until now, the virus was thought to have a minimal effect on adults other than pregnant women.
