Adolescents with Depression Followed up : Prognostic Significance of Somatic Symptoms and Their Need of In-Patient Care
- 2012

Doctoral thesis (other academic/artistic)abstract
- A dualist approach that distinguishes between mind and body is still the norm in Western medicine. Although we now know that physical and mental health are related in adults, little is known about if, or with what mechanisms, mental illnesses or depression early in life, will affect future physical and psychological health. In-between mental and somatic disorders there are somatic symptoms without medical explanation. These are symptoms that cause much suffering and impairment which are costly for society. Still little is known what they are, how they should be treated and what consequences they have for adolescents when they grow up. This study aims to investigate the long-term relationship between mental and somatic disease and the outcome of adolescents with functional somatic symptoms.The thesis is based on a 15-year follow-up study of a population-based investigation of adolescent depression. In 1991–1993 first year students in upper secondary school (age 16–17) in Uppsala, Sweden, were screened for depression (n=2300). Adolescents with positive screening and selected peers with negative screening (n=631) were assessed regarding mental health and somatic symptoms. At around age 31, the participants were followed-up in personal interviews (n=369) and national registers (n=609). Outcomes regarding mental DSM-IV diagnosis, in-patient ICD-10 disease diagnosis from the patient register, and blood vessel wall thickness were assessed.The most important finding is the unexpected poor short and long-term outcome in adolescents with somatic symptoms. The result proves the need for better treatment. The strong prediction of functional somatic symptoms for mental disorder, independent of adolescent depression, suggests that somatic symptoms and depression symptoms are different expressions of a common disorder. Female adolescents with depression need more psychiatric and somatic in-patient care but the males do not. Instead, they have considerably more in-patient stays due to alcohol and drug abuse. The males might be taken care of outside the health care system and seem to need special attention. In women with adolescent and recurrent adult depression there is an association with premature aging of the carotid wall. These women are at risk of developing early cardio-vascular disease and need early interventions.

- Adult neurogenesis, the production of newborn neurons from neural stem cells (NSCs) has been suggested to be decreased in patients with schizophrenia. A similar finding was observed in an animal model of schizophrenia, as indicated by decreased bromodeoxyuridine (BrdU) labelling cells in response to a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist. The antipsychotic drug clozapine was shown to counteract the observed decrease in BrdU-labelled cells in hippocampal dentate gyrus (DG). However, phenotypic determination by immunohistochemistry analysis could not reveal whether BrdU-positive cells were indeed NSCs. Using a previously established cell model for analysing NSC protection in vitro, we investigated a protective effect of clozapine on NSCs. Primary NSCs were isolated from the mouse subventricular zone (SVZ), we show that clozapine had a NSC protective activity alone, as evident by employing an ATP cell viability assay. In contrast, haloperidol did not show any NSC protective properties. Subsequently, cells were exposed to the non-competitive NMDA-receptor antagonist ketamine. Clozapine, but not haloperidol, had a NSC protective/anti-apoptotic activity against ketamine-induced cytotoxicity. The observed NSC protective activity of clozapine was associated with increased expression of the anti-apoptotic marker Bcl-2, decreased expression of the pro-apoptotic cleaved form of caspase-3 and associated with decreased expression of the autophagosome marker 1A/1B-light chain 3 (LC3-II). Collectively, our findings suggest that clozapine may have a protective/anti-apoptotic effect on NSCs, supporting previous in vivo observations, indicating a neurogenesis-promoting activity for clozapine. If the data are further confirmed in vivo, the results may encourage an expanded use of clozapine to restore impaired neurogenesis in schizophrenia.

- Adolescent depression is common. Earlier studies indicate that relapses and recurrences are common. But many questions are still unanswered. The aim of the present study has been to follow subjects with adolescent depressions, identified in a population-based study, over a 15-year period. Subjects with adolescent depression (n = 362) and a comparison group (n = 250) were followed in the National Swedish registers.The formerly depressed females had significantly more out-patient visits, and a significantly higher proportion (78.4% versus 69.6%) had at least one out-patient visit. Among the males, no significant differences were found as concerns out-patient visits. The formerly depressed females had significantly more in-patient stays (3.6 versus 2.4) and a significantly higher total number of in-patient days (27.4 versus 10.1). A significantly higher proportion had in-patient days due to mental disorders (9.5% versus 4.6%), in particular anxiety disorders (4.9% versus 1.0%). As concerns the males, a significantly higher proportion had in-patient days due to mental disorders (16.5% versus 1.8%), in particular alcohol and drug abuse (7.6% versus 0%).Among the formerly depressed females there were no significant differences against the comparison group as concerns the proportion of being a mother, number of children per woman, or age at first child. However, a significantly higher proportion of the formerly depressed females had had different, usually mild, disorders related to pregnancy (8.6% versus 0.6%). The children of the women with adolescent depressions were not affected.

Journal article (peer-reviewed)abstract
- BackgroundThere is a lack of population-based long-term longitudinal research on mental health status and functional physical/somatic symptoms. Little is known about the long-term mental health outcomes associated with somatic symptoms or the temporal relationship between depression and such symptoms. This 15-year study followed up adolescents with depression and matched controls, screened from a population-based sample, who reported different numbers of somatic symptoms.MethodsThe total population of 16–17-year-olds in Uppsala, Sweden, was screened for depression in 1991–1993. Adolescents who screened positive and an equal number of healthy controls took part in a semi-structured diagnostic interview. In addition, 21 different self-rated somatic symptoms were assessed. Sixty-four percent of those adolescents participated in a follow-up structured interview 15 years later.ResultsSomatic symptoms in adolescence predicted depression and other adult mental disorders regardless of the presence of adolescent depression. In adolescents with depression, the number of functional somatic symptoms predicted, in a dose response relationship, suicidal behavior, bipolar episodes, and psychotic episodes as well as chronic and recurrent depression. Contrary to expectations, the somatic symptoms of abdominal pain and perspiration without exertion better predicted depression than all DSM-IV depressive symptoms. Abdominal pain persisted as an independent strong predictor of depression and anxiety, even after controlling for other important confounders.ConclusionsSomatic symptoms in adolescence can predict severe adult mental health disorders. The number of somatic symptoms concurrent with adolescent depression is, in a stepwise manner, linked to suicidal attempts, bipolar disorders, psychotic disorders, and recurrent and chronic depression. These findings can be useful in developing treatment guidelines for patients with somatic symptoms.

- Aim: This study aims to investigate the prevalence of somatic symptoms in depressed adolescents and in their healthy peers. A second aim is to investigate the correlation, in the depressed adolescents, between the number of somatic symptoms and severe concurrent symptoms, signs and life events. Methods: The total population of 16-17 year olds - in the city of Uppsala - was screened for depression and then interviewed using a structured interview questionnaire. Depressed subjects and matched controls were identified. A total of 177 pairs were used for pair-wise analyses of somatic symptoms. Severe symptoms, signs and life events were selected for analysing their relation to depression with somatic symptoms. Results: The adolescents with depressive disorders experienced considerably more somatic symptoms than their healthy controls. The duration and depth of the depression correlated with the number of somatic symptoms. There was a strong correlation between depression with many somatic symptoms and suicidal plans/thoughts, suicidal attempts, disruptive behaviour, as well as multiple stressful relationships. Conclusion: This study demonstrates that somatic symptoms are common in adolescent depression. Multiple somatic symptoms within depression imply a higher severity in terms of duration, depth and psychiatric comorbidity. The strong correlation with suicidal plans, suicidal attempts and disruptive behaviour is concerning.

- Background. Growing evidence indicates that depression is an important risk factor for coronary heart disease. Thus, the aim of the present study has been to investigate if young women with adolescent onset and recurrent depressive disorders have signs of carotid intima and media changes already at the age of 30. Methods. Fifteen subjects with adolescent onset recurrent depressive disorders, mean age 31.5 years, were compared to 20 healthy women with a mean age of 39.6 years. The thickness of carotid artery intima and media was assessed, using non-invasive high-frequency ultrasound (25MHz). Results. The subjects with recurrent depressive disorders had significantly thicker carotid intima, significantly thinner carotid media and significantly higher intima/media ratio despite the fact that they were about 10 years younger than the healthy women. Hypertension, obesity or smoking could not explain the results. Conclusion. Already at the age of 30, subjects with recurrent depressive disorders with adolescent onset do have early signs of carotid intima and media changes, indicating a less healthy artery wall, despite otherwise no clinical signs of cardiovascular disease.

Journal article (peer-reviewed)abstract
- Purpose: Adolescent depression is associated with a range of interpersonal adversities. We hypothesized that depressed adolescents are at subsequent increased risk of problems related to intimate relationships and childbearing in adulthood, and used longitudinal data to examine this.Method: A population-based investigation of depression in 16 to 17 year olds was followed up after 15 years, at around the age of 30 years. Comparisons were made between adolescents with depression (n = 361, 78% females) and non-depressed peers (n = 248, 77% females). Data from both national registers and personal interviews were used.Results: At follow-up, the former depressed and non-depressed adolescents had become parents to a similar extent. The former depressed females were more likely than the non-depressed females to report abortion, miscarriage, intimate partner violence and sexually transmitted disease. They also reported a higher number of intimate relationships and were more likely to have divorced and to be registered as single mothers. Depressed females with a comorbid disruptive disorder had a particularly poor outcome. In the depressed females without a disruptive disorder, only those who subsequently had recurrent depressions in adulthood were at increased risk of poor outcome. There was no indication that the formerly depressed males were at increased risk of subsequent problems related to intimate relationships.Conclusion: Females with adolescent depression subsequently have problems related to intimate relationships and childbearing. Disruptive disorders and recurrence of depression appear to be instrumental in this association. Attention should be given to intimate relationship problems and sexual and reproductive health issues in young women with depression.

Mental health outcome of long-term and episodic adolescent depression : 15-year follow-up of a community sample
- 2011

Journal article (peer-reviewed)abstract
- BACKGROUND: Recent studies have highlighted the unfavourable natural course of chronic/long-term depression. We investigated the adult mental health outcome of adolescent depression, with specific focus on long-term and episodic adolescent major depression (MD). METHODS: A community sample of depressed adolescents and non-depressed peers was followed-up with a structured diagnostic interview after 15years. The participants (n=382) were divided into five groups depending on their status in adolescence: no depression (n=155); long-term MD (n=91); episodic MD (n=63); dysthymia (n=33); and subthreshold symptoms (n=40). Outcomes (age 19-31) included mood disorders, other mental disorders, suicidality, and treatment for mental disorders. RESULTS: The long-term group overall had a poorer outcome than the non-depressed group, with the episodic group in an intermediate position. The outcome of the dysthymic group was similar to that of the long-term group, while the subsyndromal group did not differ markedly from the non-depressed group. The long-term group was more likely than the episodic group to report adult anxiety disorders, multiple mental disorders, suicide attempts, and treatment; they also seemed to develop more persistent adult depressions, with a higher number of recurrent episodes and longer duration of antidepressant treatment. Even after adjustment for adolescent factors of clinical and etiological importance, the long-term group had a markedly less favourable outcome than the episodic group. LIMITATION: The participation rate at follow-up was 64.6%. CONCLUSION: Longstanding depression in adolescence is a powerful predictor of continued mental health problems in adulthood. It is now important to evaluate if early interventions can alter this severe course.

Journal article (peer-reviewed)abstract
- Background: Adolescent depression has been shown to have a range of adverse outcomes. We used longitudinal data to investigate subsequent higher education in former depressed adolescents. Method: A Swedish population-based investigation of depression in 16-17-year-olds was followed up in national registers 15 years later. Adolescents with depression (n=361, 78% females) were compared to a group of non-depressed peers of the same age (n=248, 77% females). The main outcome was graduation from higher education by age 30. Results: The adolescent with depression were less likely than their non-depressed peers to have graduated from higher education by age 30, both regarding females (27.7% vs. 36.4%, p<05) and males (12.7% vs. 28.6%, p<05). After adjustment for early school performance, socioeconomic status and maternal education, the decreased likelihood of subsequent graduation from higher education remained for depressed males (OR, 0.27; 95% CI, 0.08-0.93) but not for depressed females (OR, 0.93; 95% CI, 0.58-1.49). Conclusion: Contrary to what previous research has suggested, adolescent depression and its consequences might be particularly destructive to subsequent higher education in males.

Journal article (peer-reviewed)abstract
- PurposeThe prescription drugs have, to our knowledge, not been much studied in epidemiological samples with long-term follow-up. Accordingly, our purpose was to analyze the use of prescription drugs in adults with adolescent depression.MethodsA population-based cohort of adolescents (n = 2465) was screened for the presence of depressive symptoms and diagnosed according to a structured interview. Totally, 362 individuals were identified as depressed and compared with 250 non-depressed controls. The prescription drugs were evaluated at the age of 29-31 years from a register kept by the National Health and Welfare Board.ResultsThe formerly depressed females received significantly more prescription drugs, such as antidepressants, antiepileptics, antibacterials, antimycotics, and antihistamines for systemic use as well as other drugs, compared with controls (15.6 +/- 27.4 vs 8.2 +/- 7.4 recipes, p < 0.001). Formerly depressed males did not differ from controls regarding prescription drugs.ConclusionsThe females but not males with adolescent depression subsequently received more prescription drugs than non-depressed peers. Depressed female adolescents received more psychotropic and non-psychotropic drugs later in life compared to the non-depressed. This might be as a result of physical illnesses, different treatment-seeking behaviors, or somatizing reactions.
