The oldest drugs on the market are not prescribed often, but may be a good option for some women. These include tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs). TCAs may cause side effects like dry mouth, constipation, or dizziness. MAOIs can cause sedation, insomnia, dizziness, and weight gain. To avoid the risk of a rapid rise in blood pressure, people taking MAOIs must also avoid eating a substance called tyramine, found in yogurt, aged cheese, pickles, beer, and red wine. Some drug side effects subside with time, while others may lessen when a drug dose is lowered. Research
Differences in the brains structure and function appear to be present in adolescents with depression though this may depend on age. Younger adolescents, mostly under the age of 18, with depression have shown greater white matter volume within frontal regions of the brain, greater cortical thickness in the anterior cingulate cortex and medial orbitofrontal cortex, as well as greater functional connectivity between cortico-limbic brain regions. Whereas older adolescents, mostly above the age of 18, appear to show lower cortical surface area in regions including the lingual, occipital gyri, as well as medial orbitofrontal and motor cortices. Results such as these have led to the hypothesis that the biological causes of depression may in part be neurodevelopmental, with its biological underpinnings forming early on in brain development.
Depression is a mental disorder characterized by prolonged unhappiness or irritability, accompanied by a constellation of somatic and cognitive signs and symptoms such as fatigue, apathy, sleep problems, loss of appetite, loss of engagement; low self-regard or worthlessness; difficulty concentrating or indecisiveness; or recurrent thoughts of death or suicide. Depression in childhood and adolescence is similar to adult major depressive disorder, although young sufferers may exhibit increased irritability or behavioral dyscontrol instead of the more common sad, empty, or hopeless feelings seen with adults. Children who are under stress, experiencing loss, or have other underlying disorders are at a higher risk for depression. Childhood depression is often comorbid with mental disorders outside of other mood disorders; most commonly anxiety disorder and conduct disorder. Depression also tends to run in families. In a 2016 Cochrane review cognitive behavior therapy (CBT), third wave CBT and interpersonal therapy demonstrated small positive benefits in the prevention of depression. Psychologists have developed different treatments to assist children and adolescents suffering from depression, though the legitimacy of the diagnosis of childhood depression as a psychiatric disorder, as well as the efficacy of various methods of assessment and treatment, remains controversial. Base rates and prevalence
About 8% of children and adolescents suffer from depression. In 2016, 51 percent of students (teens) who visited a counseling center reported having anxiety, followed by depression (41 percent), relationship concerns (34 percent) and suicidal ideation (20.5 percent). Many students reported experiencing multiple conditions at once.
