The test could conceivably help parents who are worried about gender-related diseases, but it could also allow people to wade into the morally murky waters of sex selection. The test analyzes fetal DNA found in a mother's blood, according to a report in the New York Times.
As most dementia is associated with Alzheimer's, dementia typically worsens with age. Unlike delirium, which is reversible, dementia is frequently caused by permanent damage to the brain's nerve cells. This damage can be caused by things like other illnesses, injuries, and even the genetic make-up of a person.
One thing to keep in mind though is that both schizophrenia and dementia affect the same section of the brain. However, if the patient has late onset schizophrenia (after the age of 40), the likelihood of impending dementia is increased. The likelihood for Alzheimer's remains the same however as the general population.
