Genetic conditions. Sometimes an intellectual disability is caused by abnormal genes inherited from parents, errors when genes combine, or other reasons. Examples of genetic conditions are Down syndrome, fragile X syndrome, and phenylketonuria (PKU).
Problems during pregnancy. Intellectual disabilities can result when the baby does not develop inside the mother properly. For example, there may be a problem with the way the baby's cells divide as it grows. A woman who drinks alcohol or gets an infection like rubella during pregnancy may also have a baby with intellectual disabilities.
Problems at birth. If a baby has problems during labor and birth, such as not getting enough oxygen, they may have an intellectual disability.
Health problems. Diseases like whooping cough, the measles, or meningitis can cause intellectual disabilities. This can also be caused by extreme malnutrition (not eating right), not getting enough medical care, or by being exposed to poisons like lead or mercury.
Hi-tech mobility for the blind and visually impaired Ray was designed to provide a handheld, lightweight and compact supplement to traditional canes for the blind. It is a small, extremely sensitive electronic mobility aid that senses obstacles and alerts the user by emitting audible or vibrating signals (or both.) Ray features easy 2-button operation and is so compact that it can fit in the palm of your hand.
Using an ultrasonic emission similar to the cone of light of a flashlight, Ray can recognize obstacles up to a distance of 9.35 feet (2.85 meters) away and announce them to the user via an audible or vibrating signal.
