   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caring sciences; Vårdvetenskap;

   Abstract : The aim of this thesis is to study prevalence of winter depressive mood and treatment effects of bright light for persons with winter fatigue and winter depression. Study I is a cross-sectional survey of a random sample (N=1657) from the general population between 18-65 years of age in Dalarna, Sweden (latitude 60°N). READ MORE

4. 2. Winter Depression: Clinical, Psychosocial and Biochemical Characteristics

   Author : Baba Pendse; Lund Psykiatri; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NPY.; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik; CRH; Social characteristics; Psychopathology; Temperament; Nonseasonal major depression; Suicide attempt; Winter depression; SAD;

   Abstract : Seasonal Affective Disorder with depressive episodes during the autumn/winter seasons (winter depression) is common. Outpatients with winter depression were studied regarding temperament, psychopathology, social characteristics, psychosocial functioning and the neuropeptides corticotropin - releasing hormone (CRH) and neuropeptide Y (NPY), which are known to be involved in stress-regulation.

5. 3. Seasonal aspects of peripartum depressive symptoms

   Author : Hanna E. Henriksson; Alkistis Skalkidou; Fotios Papadopoulos; Sara M Sylvén; Stavros I Iliadis; Lauren M. Osborne; Uppsala universitet; []
   Keywords : peripartum depressive symptoms; pregnancy; postpartum; seasonality; meteorological parameters; inflammatory markers; proximity extension assay; metabolomics; gas chromatography-mass spectrometry;

   Abstract : Every year, a large proportion of pregnant and newly delivered women develop peripartum depression, a condition that may cause long-term suffering for the entire family. Although there is a lack of consensus, some studies propose an association between season and the risk of developing depression during pregnancy and the postpartum period. READ MORE

6. 4. Distribution and abundance of genetic variation in the arctic fox

   Author : Love Dalén; Anders Angerbjörn; Robert K. Wayne; Stockholms universitet; []
   Keywords : population genetics; DNA; ecology; population history; gene flow; Alopex lagopus;

   Abstract : This thesis investigates how changes in population size and spatial movements of individuals have shaped the distribution and abundance of neutral genetic variation in the arctic fox. This is done through mitochondrial and microsatellite DNA analyses on samples covering most of the species’ distribution, but with special emphasis on Scandinavia. READ MORE

7. 5. Genetic and experimental studies of seasonal affective disorder and related phenotypes

   Author : Carolina Johansson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Seasonal affective disorder (SAD) is a subtype of recurrent depressive or bipolar disorder, in which episodes reoccur and remit during a particular season each year. A genetic component in vulnerability to winter SAD has been suggested, and the goal of this thesis was to increase the understanding of SAD and seasonal variations in mood, by obtaining self-report assessments of related traits, examining genetic variations in genes hypothesised to influence the phenotypes in question, and to investigate effects of different photoperiods and stress in an animal model.
