Longitudinal studies in Major Depressive Disorder (MDD), cognitive functioning and cortisol profiles.

Hammar is head of the node Bergen Mood and Cognitive Function Group (MCF) with several doctoral candidates been working with issues dealing with major depression, cognitive functioning and longitudinal studies. Data collection has been conducted in three large main studies and Hammar is the principal investigator for all projects included in these studies.  

All investigations include a comprehensive neuropsychological test battery, consisting of both experimental and standardized tests, cortisol measurements with dexamethasone, self-reports concerning cognitive functioning, quality of life, working capacity, coping strategies, ruminative style and dysfunctional attitudes. Some patients have been investigated with fMRI.

The first study is a literature of the longest follow-up studies within a group of patients who suffer from recurrent depression and examining cognitive functioning over a 10 year period.

The other main project is a longitudinal study that included patients with recurrent depression.

The third major project is one of the first worldwide to collect a patient group of first episode depressed patients and follow them over time.

Several findings are generated from these data and materials published in international journals (see publication list).

Another major project is currently collecting data from patients in remission.

Further, we are currently conducting a 5-year follow-up on the first episode patient group.

Hammar is also a partner in various projects that examine children with autism, patients with anxiety, bipolar patients receiving ECT treatment, biological markers in adolescents who survived the Utøya massacre.

 

 

 

 

 

 

Since 1997 I have been a lecturer at the Professional studies in Psychology at UiB, including both biological psychology and neuropsychological courses (including master’s and bachelor’s level), as well as several other teaching activities. I have also been lecturing in psychological courses for the Master’s training in Logopedy at UiB between 2001-2010.000
