    • Characteristics of Patients Who Complete Suicide and Suicide Attempts While Undergoing Treatment in Norway: Findings from Compensation Claims Records 

      Krvavac, Sanja; Bystad, Martin Kragnes; Wynn, Rolf; Bukholm, Ida Rashida Khan; Jansson, Billy (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-24)
      The aim of this study was to identify characteristics that differentiate patients who complete suicide (SC) from patients with suicide attempts (SA) while undergoing treatment in Norway. We examined data from the Norwegian System of Patient Injury Compensation (Norsk Pasientskade Erstatning—NPE). Data were extracted from NPE case records from a 10-year period (2009–2019) for 356 individuals who ...

      Bystad, Martin Kragnes; Bjørhovde, Njål; Larsen, Yvonne; Aslaksen, Per M; Riley, Henriette (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-03)
      Akuttpsykiatriske enheter gir øyeblikkelig hjelp til pasienter med særlig vanskelige og kompliserte tilstander med behov utover det som kan ivaretas i kommunehelsetjenesten eller ved distriktspsykiatriske senter (DPS).<p> <p>Flere studier har de siste årene sett på antallet innleggelser og hyppigheten av tvangsbruk i akuttpsykiatriske enheter i Norge (Bjerke et al., 2019; Tøgersen et al., 2015; ...

    • Fear of diseases among people over 50 years of age : a survey 

      Bystad, Martin Kragnes; Grønli, Ole Kristian; Lilleeggen, Camilla; Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-11)
      The aim of this study was to investigate the association between well-known diseases and fear of them in individuals over 50 years of age. Information on the fear of diseases can be relevant for both public health information purposes and clinical setting diagnostics. However, very few studies have investigated the fear of diseases in individuals over the age of 50. We used an electronic survey ...

    • A four-month home-based tDCS study on patients with Alzheimer’s disease 

      Grønli, Ole Kristian; Rasmussen, Ingrid Daae; Aslaksen, Per M; Bystad, Martin Kragnes (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-19)
      In the present open-label study, our first aim was to study the tolerability and feasibility of long-term treatment with transcranial direct current stimulation (tDCS) and the second aim was to measure whether the treatment led to cognitive improvement. Participants with AD used a tDCS home-treatment kit inducing a low current (2 mA) via two scalp electrodes 30 minutes daily for 4 months. A total ...

    • High-Definition Transcranial Direct Current Stimulation Improves Delayed Memory in Alzheimer’s Disease Patients: A Pilot Study Using Computational Modeling to Optimize Electrode Position 

      Rasmussen, Ingrid Daae; Boayue, Nya Mehnwolo; Mittner, Matthias; Bystad, Martin Kragnes; Grønli, Ole Kristian; Vangberg, Torgil Riise; Csifcsak, Gabor; Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-14)
      Background: The optimal stimulation parameters when using transcranial direct current stimulation (tDCS) to improve memory performance in patients with Alzheimer’s disease (AD) are lacking. In healthy individuals, inter-individual differences in brain anatomy significantly influence current distribution during tDCS, an effect that might be aggravated by variations in cortical atrophy in AD ...

    • How can placebo effects best be applied in clinical practice? A narrative review 

      Bystad, Martin Kragnes; Bystad, Camilla; Wynn, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-29)
      Placebo effects are documented in a number of clinical and experimental studies. It is possible to benefit from placebo effects in clinical practice by using them as effects additive to those of documented and effective treatments. The purpose of this paper is to discuss how doctors and other health workers may benefit from placebo effects within an ethical framework. A narrative review of the ...

    • Nevropsykologiske senskader hos boksere: en systematisk gjennomgang 

      Skogseth, Helene; Eriksen, Maria Thorseth; Bystad, Martin Kragnes; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-30)
      Background: The aim of this systematic review was to investigate the risk of neuropsychological sequelae from boxing.<p> <p>Method: We conducted a systematic search in the databases Medline, Embase, PsychInfo and Web of Science. Studies with boxers, control groups, using neuropsychological assessment and brain-imaging/biomarkers were included. Nine articles met these criteria.<p> <p>Results: ...

    • Patients Who Die by Suicide: A Study of Treatment Patterns and Patient Safety Incidents in Norway 

      Krvavac, Sanja; Jansson, Billy; Bukholm, Ida Rashida Khan; Wynn, Rolf; Bystad, Martin Kragnes (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-27)
      Underlying patterns and factors behind suicides of patients in treatment are still unclear and there is a pressing need for more studies to address this knowledge gap. We analysed 278 cases of suicide reported to The Norwegian System of Patient Injury Compensation, drawing on anonymised data, i.e., age group, gender, diagnostic category, type of treatment provided, inpatient vs. outpatient status, ...

    • The relation of hippocampal subfield volumes to verbal episodic memory measured by the California Verbal Learning Test II in healthy adults 

      Aslaksen, Per M; Bystad, Martin Kragnes; Ørbo, Marte; Vangberg, Torgil Riise (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-08)
      Total hippocampal volume has previously been shown to correlate with performance on tests for verbal episodic memory. However, there are sparse evidence on how hippocampal subfield volumes are related to verbal episodic memory in healthy adults. The present study investigated the association between volumes of separate hippocampal subfields and verbal episodic memory performance in healthy volunteers. ...

    • Relaxation techniques as an intervention for chronic pain: A systematic review of randomized controlled trials 

      Vambheim, Sara Magelssen; Kyllo, Tonje; Hegland, Sanne; Bystad, Martin Kragnes (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-20)
      Chronic pain increases the risk of sleep disturbances, depression and disability. Even though medical treatments have limited value, the use of prescription-based analgesics have increased over the recent years. It is therefore important to evaluate the effect of non-pharmacological treatments. A systematic search for studies evaluating the effect of relaxation techniques on chronic pain was ...

    • Transcranial Direct Current Stimulation as a memory enhancer in healthy participants and patients with Alzheimer`s disease

      <p>The aim of this thesis was to investigate the effects of transcranial direct current stimulation (tDCS) as a memory enhancer in Alzheimer’s disease patients and healthy individuals. In addition, we wanted to study how verbal memory functions are related to hippocampus subfield volumes. <p>This thesis consists of three reports, in which two of the reports (I and II) aimed to study the effects of ...
