Depression and Genetic Predisposition
Depression and Genetic Predisposition: Can depression be genetic? I find the articles of most interest to be those that seem to be making a lot of progress in the study of genetics and mental illness including a genetic link to ADHD. Even though these studies are in the very early stages, they shed some new light on mental illness and "maybe" some promise of a break through down the road. Depression and genetic predisposition is in the forefront of many studies today. Can depression be genetic or is depression genetically inherited are questions that are often asked of me. Is there a suicide gene? Certain studies have claimed to isolate parts of the brain and genes that may be responsible for depression; and other articles claim that the environment can alter the genes which would give someone a predisposition to depression or other mental illnesses. Still other research has claimed that toxins or deficiencies or a plethora of vitamins in early development can also lead to mental illness.
To say that the cause of an illness of any sort is genetic is somewhat of a vacuous answer. We can then ask what was the cause of the illness in the ancestor that passed this gene along; and on and on we go. Somewhere in the family of origin, somebody had to be the "prime cause" or "first cause" that introduced this illness to the family gene pool. Now the question of whether the prime cause was a gene mutation or environmental issue cannot be avoided. This also entails another issue viz. if mental illness is initially introduced to a particular gene pool by means other than DNA, then of logical necessity-mental illness can still be caused by factors other than DNA. The question then becomes, what are some of the possible causes of mental illness, are they biological, genetic mutations, environmental stressors, toxins...
