Causes
Changes in a person's energy level, sex drive, sleep patterns, self-esteem, concentration, drug or alcohol use can be signs of an oncoming mood disorder.
Many different things might trigger mood swings, from unhealthy diet or life style to drug abuse or hormonal imbalance.
A major cause of mood swings is hyperactivity sometimes accompanied by inattentiveness, symptoms associated with Attention deficit hyperactivity disorder. If the mood swing is not associated with a mood disorder, treatments are harder to assign. Most commonly, however, mood swings are the result of dealing with stressful and/or unexpected situations in daily life.
