You might worry that you could develop or 'catch' the same illness as your ill parent – but you cannot catch a mental illness from anyone. People might say 'it runs in families' or talk about the genetics or genes causing the illness.
One of the most highly genetically inherited psychiatric disorders is bipolar disorder which may affect as much as 1-4% of the population. Bipolar disorder is characterized by periods of depression followed by periods of abnormally elevated mood (mania/hypomania).
Susceptibility is passed on in families through genes. Experts believe many mental illnesses are linked to abnormalities in many genes rather than just one or a few and that how these genes interact with the environment is unique for every person (even identical twins).
Studies on twins and close family members have found that genetics play a role at a rate of 30-50% . Similar to depression, the genes that influence the development of anxiety aren't fully understood.
Past studies have reported that offspring of affected mothers have a higher risk of schizophrenia than the offspring of affected fathers; however, other studies found no such maternal effect [Gottesman and Shields, 1976].
The answer to this question is also thought to be most likely yes. Experts do believe that bipolar disorder can skip generations. It's also thought that a combination of environment, childhood nurturing, and genetic makeup can all increase the chance of developing bipolar disorder.
Bipolar disorder is the most likely psychiatric disorder to be passed down from family. If one parent has bipolar disorder, there's a 10% chance that their child will develop the illness. If both parents have bipolar disorder, the likelihood of their child developing bipolar disorder rises to 40%.
Certain mental disorders tend to run in families, and having a close relative with a mental disorder could mean you are at a higher risk. If a family member has a mental disorder, it does not necessarily mean you will develop one. Many other factors also play a role.
Among the traits found most strongly determined by heredity were ambition, vulnerability to stress (neuroticism), leadership, risk-seeking, a sense of well-being and, surprisingly, respect for authority.
Your genes and family history. Your life experiences, such as stress or a history of abuse, especially if they happen in childhood. Biological factors such as chemical imbalances in the brain.
Depression does not have a clear pattern of inheritance in families. People who have a first-degree relative (for example, a parent or sibling) with depression appear to have a two to three times greater risk of developing the condition than the general public.
Many individuals with bipolar disorder have relatives with other mood, anxiety, and psychotic disorders (such as depression or schizophrenia). These disorders may run in families in part because they share some genetic risk factors with bipolar disorder.
When Is It Time to Walk Away? In some cases, the decision to leave is obvious. If physical abuse is present to any degree, and especially if the individual fears for their own life or well-being or that of their children, it's important to leave as soon as possible. Safety is the number one priority.
The outward signs of a mental illness are often behavioral. A person may be extremely quiet or withdrawn. Conversely, they may burst into tears, have great anxiety or have outbursts of anger. Even after treatment has started, someindividuals with a mental illness can exhibit anti-social behaviors.
Without treatment, the consequences of mental illness for the individual and society are staggering. Untreated mental health conditions can result in unnecessary disability, unemployment, substance abuse, homelessness, inappropriate incarceration, and suicide, and poor quality of life.
Where does mental illness begin? New research suggests the seeds of psychological problems are planted well before birth. Schizophrenia, for example, is often thought of as a genetic disorder.
There is clear research showing that anxiety is influenced by our genetics. In fact, experts noticed a family connection for anxiety even before they understood how DNA or genes worked. If you have a close relative with anxiety, your chance of developing it is about 2 to 6 times higher than if you don't.
Genetics. Schizophrenia tends to run in families, but no single gene is thought to be responsible. It's more likely that different combinations of genes make people more vulnerable to the condition. However, having these genes does not necessarily mean you'll develop schizophrenia.
Defects in mitochondrial DNA sequences may contribute to a predisposition to such complex diseases as diabetes and bipolar disorder. Therefore, if all bipolar disorder patients have mitochondrial predisposition genes, then the transition of bipolar disorder from the mother's side would be higher.
Drugs with a definite propensity to cause manic symptoms include levodopa, corticosteroids and anabolic-androgenic steroids. Antidepressants of the tricyclic and monoamine oxidase inhibitor classes can induce mania in patients with pre-existing bipolar affective disorder.
