Mothers of kids with disabilities might be more forgetful，as they age than other mothers， according to a new study.And mothers with a strong support system，a sense of control and a history of regular exercise kept sharper than the other mothers.However, fathers of disabled children did not differ from fathers of non-disabled children in memory skills as they aged.

That’s not surprising，considering past research that has shown parents with disabled kids tend to feel more stressed and to have more psychological problems like depression.In the study, parents were tested on memory and fluency,reasoning,working memory and ability to switch their attention.Physical health，physical activity,depression，sense of control，social support and negative parenting experience were also included.

The mothers of disabled kids tended to be much more depressed，in worse physical health and to feel they had less of a sense of control than mothers without disabled kids.For instance， 18 percent of mothers of disabled children reported having been depressed in the 12 months prior to the study, compared with 7 percent of mothers without disabled kids.Mothers of disabled children also had less support from friends than women without disabled children.Besides，among the women with disabled children，being more educated and having more social support were linked to significantly better memory ants thinking.

Fathers with disabled kids had more negative parenting experiences than fathers whose kids were not disabled.The researchers did not have information about the severity(严重)of the children’s disabilities，their ages，or about any disabilities or other health problems among the parents.They acknowledge in their report that because they only looked at one point in time， they cannot say whether parenting a disabled child caused the memory differences they observed.

One afternoon in December 2013，Lauren Robinson walked into her eighth-grade science class，and immediately knew something was wrong.A wave of dizziness washed over her and she started to vomit(呕吐).Worst of all，Lauren was soon struggling to breathe.

Since birth，Lauren has suffered from an allergy(过敏症)to dairy products.But she had not eaten any dairy products that day,and in her science class，there were no dairy products in sight.Hours earlier;there had been a pizza party in the room，but every surface had been wiped down.What no one realized was that invisible particles of cheese still hung in the air.

After her attack in science class，Lauren was rushed to the hospital.She made a full recovery, but the idea of returning to school seemed so dangerous that Lauren and her family decided she would not go back.Instead，a teacher started coming to her house.Lauren was safe，but she missed her friends.

Then Lauren and her family learned about a possible solution：a remote-controlled robot that Lauren could send to school in her place.Lauren became excited by the way the robot—called VGO—allowed her to interact with others.

Here’s how the VGO works：Using art app on her laptop(笔记本电脑)，Lauren controls the VGO from home.The robot’s video camera and microphones allow her to see and hear what’s going on at school as she drives the robot from class to class.Her teachers and classmates can see and hear her too;her face appears on a screen and speakers project her voice.She has figured out a way to“raise her hand”using the robot’s headlights.“I flash them on and off until the teacher sees me，”she explains.
