I’ve been looking forever on Google and can’t find a straight-up answer to this question! I just need a list of hereditary mental disorders that have come from a legit website or source (please include). THANK YOU!

There isn’t really a straight up answer….. There is no proof that any of them are.. but there is very strong evidence that many are….. it is also common to have families where there seems to be a tendancy to develop mental disorders but they all have different ones….. Schizophrenia and Bipolar are definitely genetic…. Anxiety Disorders (Panic/OCD, etc…) seem to run in families. Addiction also seems to have a genetic component…. some people just have a genetic lack of resistance to addiction, especially alcoholism. Now it seems that there may be a genetic predisposition to developing personality disorders.. which would explain why given the same upbringing some people end up ill and others end up fine….. No mental disorder is guaranteed to develop given a certain set of genes….. even if both of your parents have Bipolar there is only a 20% chance of you getting it…. even in identical twins, if one twin has it the other only has a 50% chance of getting it….. So no absolute proof that any of them are genetic but lots of evidence that most, if not all, of them have some sort of genetic component, whether directly due to genes (like Bipolar) or just a disposition that leaves you suseptible (like addiction and personality disorders).
