My late grandpa has schizophrenia. and i think i have bipolar. if ever that i have bipolar, is it possible because of the genes from my grandpa?

Bipolar disorder: and schizophrenia are not the same disorder. We ALL have tendencies toward certain disorders but what turns the genes on and off is still being researched in a field of science called "epigenetics." We know that we are not at the mercy of our genes. Please see a mental health professional for an exam and do not get fixed ideas into your head. Peace and good health.

Not so simple: Schizophrenia and bipolar disorder are separate disorders. Some studies suggest an increased risk in families with these disorders, however, these disorders are multifactorial meaning they have many different etiologies. While Genes may increase your risk they are not the only reason for the presence of the disorder. Go see a mental health provider and continue to be strong and focused.
