the Genetic Links to Psychosis and Family Dynamics

Regarding the issues of mental illness and genetics!

Hello Doctor, I would like to ask you a question.
My mother has a history of dementia and has been managing it with medication for over a decade, but she occasionally experiences more severe episodes (e.g., outbursts of anger, throwing things, irrationally suspecting others...).
The intrusive thoughts have never ceased, but as long as they are not severe, the family has gotten used to them.
Earlier this year, my father passed away, and my mother may have been greatly affected by this loss and has lost her sense of stability, completely refusing to take her medication.
Whenever she is upset, she lashes out or suspects those around her, which has put a lot of pressure on the entire family.
Although I do not live at home, I become extremely anxious whenever I hear any commotion at home, which has been distressing for me lately.
I often feel like I want to yell at my mother and tell her to go to the hospital.
I am generally well-liked and the life of the party, and I have friends who help me when I face problems, but despite this, I worry that I might end up like my mother.
I would like to ask if delusional disorder is related to genetics? Is the hereditary risk high? Is it normal for me to have thoughts like “I want to yell at my mother and tell her to go to the hospital”? P.S.
Two years ago, due to personal issues, I sought psychological counseling and saw a psychiatrist once.
The doctor mentioned that I had mild depressive tendencies and prescribed medication to help with sleep for about three months, and I have since recovered.
Thank you.

Most mental illnesses have unclear causes.
Although many studies show that schizophrenia, bipolar disorder, and even alcoholism and certain personality disorders are related to genetics, there have not been any groundbreaking discoveries.
In families with individuals who have delusions, other family members may have a slightly higher chance of experiencing delusions as well, but attributing this solely to genetics is somewhat arbitrary, so I think you need not worry too much.

Understanding the genetic links to psychosis and family dynamics is a complex and multifaceted issue. Your concerns about your mother's history of delusional disorder, especially following the loss of your father, are entirely valid and reflect the emotional turmoil that can arise in families dealing with mental health issues.

Firstly, it is important to recognize that mental health disorders, including delusional disorder, can have both genetic and environmental components. Research indicates that there is a genetic predisposition to various psychiatric conditions, including psychosis. For instance, if a close family member has a psychotic disorder, the likelihood of developing a similar condition can be higher than in the general population. However, this does not mean that you will inevitably develop such a disorder; genetics is just one piece of the puzzle.

The heritability of psychotic disorders varies, but studies suggest that individuals with a family history of schizophrenia or related disorders may have a higher risk. For example, the risk of developing schizophrenia is about 10% if a first-degree relative is affected, compared to about 1% in the general population. However, it's crucial to understand that many people with a family history of mental illness do not develop these conditions, indicating that environmental factors, personal experiences, and coping mechanisms also play significant roles.

Your mother's current behavior, including her refusal to take medication and her episodes of anger and suspicion, can be exacerbated by the stress of losing your father. Grief can significantly impact mental health, leading to a deterioration in symptoms for individuals with pre-existing conditions. It is not uncommon for family members to feel overwhelmed and anxious in such situations, especially when they perceive a threat to their emotional well-being or safety.

Regarding your feelings of wanting to lash out at your mother, it is essential to acknowledge that these emotions are a natural response to stress and frustration. Caregiving for someone with a mental illness can be incredibly taxing, and it is common to feel anger or resentment, especially when you feel helpless. However, expressing these feelings in a constructive manner is crucial. Instead of resorting to harsh words, consider seeking ways to communicate your concerns calmly and compassionately. It may also be beneficial to involve a mental health professional who can mediate discussions and provide support for both you and your mother.

Your previous experiences with therapy and medication indicate that you have taken steps to address your mental health, which is commendable. It is essential to continue prioritizing your well-being, especially as you navigate these challenging family dynamics. Engaging in self-care practices, seeking support from friends, and possibly returning to therapy can help you manage your feelings and reduce anxiety about your mother's condition.

In summary, while there may be genetic links to psychosis, environmental factors and personal experiences significantly influence mental health outcomes. Your feelings of frustration and concern are valid, and addressing them through constructive communication and self-care is vital. If your mother's behavior continues to escalate, it may be necessary to seek professional intervention to ensure her safety and the well-being of your family. Remember, you are not alone in this, and support is available.
