New research suggests that although genes play a role in predisposition to mood disorders, they may not be the determining factor.

A study published in a new issue of Biological Psychiatry found that animals raised in small social groups were more likely to be aggressive and anxious, particularly those with a low activity MAOA genotype.

A specific mutation in the MAOA gene has been linked to violent behavior. However, the study also determined that animals reared in larger social cages were less aggressive irrespective of their MAOA status.

This suggests “animals that were raised in rich, complex settings with mothers, other kin and peers, were completely protected from the potentially deleterious effects of having the ‘risky’ form of the MAOA gene,” says Dr. John Capitanio, senior study author.

The results open a way to a range of prevention and treatment methods that include behavioral, cognitive and natural therapies to help people suffering from anxiety and depression improve their quality of life.

Besides herbal supplements, individuals may choose from a range of mind-body techniques such as breathing exercises, physical exercise, yoga, tai chi, hypnosis or meditation.

Some people also respond to aromatherapy, including essential oils, massage oils or infusers used in the bath.

Essential oils that are used for anxiety include bergamot, cypress, geranium, jasmine, lavender, melissa, rose and sandalwood.
