Is there a genetic link to depression?
Depression is known to run in families, suggesting that genetic factors contribute to the risk of developing this disease. However, research into the genetics of depression is in its early stages, and very little is known for certain about the genetic basis of the disease.
What genes are associated with depression?
The serotonin transporter gene and genes involved in the serotonergic system are candidate genes for susceptibility to depression given that many antidepressant medications act on these systems. Several studies have implicated the serotonin transporter gene (SLC6A4) in MDD [17–19].
What mental illness can be passed down genetically?
Scientists have long recognized that many psychiatric disorders tend to run in families, suggesting potential genetic roots. Such disorders include autism, attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depression and schizophrenia.
Can genetics cause anxiety?
Most researchers conclude that anxiety is genetic but can also be influenced by environmental factors. In other words, it’s possible to have anxiety without it running in your family. There is a lot about the link between genes and anxiety disorders that we don’t understand, and more research is needed.
What are the biological causes of depression?
The predisposition to developing depression can be inherited. Other biological causes for depression can include physical illness, the process of ageing and gender. Stress can trigger depression but understanding its particular meaning to the person is important.
Is depression biological or psychological?
In general, depression can be due to a number of factors including stresses which can range from mild to severe, combined with vulnerability or predisposition to depression that can result from biological, genetic or psychological factors. Each type of depression is associated with different mixtures of causes.
