Dementia may begin in the womb, new study suggests
In tissue samples of the brains of 54 people, 40 of whom had varying forms of dementia, scientists discovered that half had spontaneous flaws in their DNA, which may have contributed to their illness.
The scientists believe the genetic defects occurred before the people were even born, while they were embryos growing in the womb. And they fear that the same mutations may be carried by a huge number of the population, which is why dementia is so prevalent.
