What are my or my sister's (22 years old) chances of inheriting schizophrenia from our mom?
and I hope I posted this in the right categoryChances of someone inheriting schizophrenia from their parents?
Autism is a form of neurology (commonly called a disability) that one is born with. It has a strong genetic component and runs in families, mostly on the male side. Fathers, sons, and brothers are more likely to have autism if one of the others do.
Schizophrenia is not considered a neurological disability; it is classified as a mental disease. It usually occurs after childhood. It has more to do with chemical imbalances in the brain, abuse, or traumatic brain injury than with the basic wiring of the nerves that we are born with. Thus, the genetic component for schizophrenia is much more limited than in autism. However, there may be family related matters that contribute to a second family member developing it due to common environmental issues, such as lifestyle, abuse, or trauma.
Note:
Historically, these diagnoses were lumped together. Even today, there are two major movements ongoing that are respectively promoting the merging of autism and Aspergers diagnoses as one condition (for clinical convenience) and renaming autism as Childhood Schizophrenia. Neither of these movements have their foundation in genetic research or neuroscience. In my professional opinion, both these movements are more damaging than beneficial to the public. Moreover, they confuse again the understanding of the distinctiveness of autism and schizophrenia by equating neurological disabilities with mental diseases.
