Hello,
Your son's wife shows abusive, violent behavior with extreme mood swings. It is commonly caused due to
bipolar disorder. However, such behavior may also get triggered due to clinical
depression (caused by
substance abuse, use of certain medications, past major event-unrevealed, past abuse, genetics, death/loss, being over ambitious, etc.). Sometimes, the intense mood shifts can range from
mania to depression. Not all patients suffer from depression.
Many people with bipolar disorder may experience periods of anger, irritability, and rage. If left untreated such patients may at times become uncontrollable and even dangerous for others. You are suggested to get a treated by treated by a
psychiatrist but before that get a complete medical check up done so that treatment can be done. Once she is diagnosed with some mental problem, she will get treatment. If she improves the issues will get solved.
Take care. Hope I have answered your question. Let me know if I can assist you further.
