The Power of Genes; I was borned to be depressed

by The Anti Depression Team on

The inheritance of particular genes can affect peoples’ behavior, increasing their likelihood of becoming depressed. However, it is doubtful whether one single gene or gene combination can be held accountable for all the different types of depression known.

Should depression be an inheritable trait, it would occur more frequently in identical twins that have the same genes than ordinary siblings or fraternal twins. Hence, twins who have been separated early are used in research to evaluate the significance of environments in making people depressed.

A child’s risk of becoming depressed is multiplied when the family consists of many individuals with psychological problems. If one parent was diagnosed to be depressed, the child’s risk of becoming depressed would be at 25 to 30 percent. If both parents had psychological disorders and one was bipolar, the child’s risk of becoming depressed could be as high as 50 to 75 percent. Almost two-thirds of bipolar patients had relatives with psychological problems, but the actual correlation between one’s genes and being depressed has not been certified yet.

Gene-mapping research using recombinant DNA revealed that a single mutation had caused bipolar disorders in some families. These gene mutations are non-identical for the families and may not occur in all bipolars.

Should a gene be responsible for raising one’s likelihood of becoming depressed, how does it influence the signs of being depressed? It could contain information for the manufacture of enzymes (such as tyrosine hydroxylase) that is integral to the creation of neurotransmitters linked to psychological disorders.
