Disease can be seen as the antechamber of death.
Are there reliable tests for predicting disease? The short answer is: not for Alzheimer’s or other common diseases. Tests do exist for some specific diseases, most with known familial predispositions, such as Huntington’s disease, cystic fibrosis, Duchenne’s dystrophy and many more.
The basis for most of the severe mental disorders is in your genes and the early development of the brain. But we will not be able to find THE cause of these disorders. Why not?
Monozygoicic twins share the same genes, but are not exact replicas of each other. How can this be? A result of what they – separately – have experienced? Or is it chance? How then?
Is it Nature or Nurture, congenital or acquired? The answer is actually quite simple: everything is Nature and Nurture. The structure of the brain determines what we can learn and what we learn determines the structure of the brain.
The probability of having autism is greater for an individual if it runs in their family. This suggests hereditary factors. But what do you actually inherit? What you inherit is a predisposition for a specific development of your brain. This, together with what you experience while growing up, can lead to the development of a mild to severe form of autism.
