A person with anxiety, depression, schizophrenia and many other mental illnesses have a tendancy to also have a family history of the illness.
Having a blood relative with an certain type of behavioral illness will most likely be apparent within the same family.
But also hormones are responsible for a number of human functions. Hormones have a huge impact on human behavior, especially mood. The endocrine system which is made up of the hypothalamus, putitary gland, the pineal body, thyroid gland, parathyroid glands, thymus, pancreas, adrenal glands, ovaries and testes all secrete different hormones. Many people become aware of hormones at the onset of puberity.
The thyroid gland that is responsible for metabolism is also responsible for a number of human behaviors. “An overactive gland can produce a variety of symptoms: overexcitability, insomnia, reduced attention span, fatigue, agitation, acting out of charcter, and snap decisions, as well as reduced concentration and difficulty focusing on a task.” (Morris and Maisto, 2005). Just as the thyroid gland is responsible for hormones that affect a number of behavioral symptoms, so too are other glands.

Testosterone has been attributed to triggering aggression although women can be aggressive also if they have high levels of...
