The present study aimed to assess the efficacy of a group-based, brief transdiagnostic cognitive-behavioral therapy (CBT) program for adolescents with internalizing problems, such as anxiety and depressive disorders, seeking help in a primary health care clinic in Iceland. The group-based CBT program consisted of eight weekly 110-min sessions covering psychoeducation, cognitive restructuring, behavioral activation, exposure, problem-solving, social skills, and mindfulness. The study recruited 53 participants, who were randomly assigned to either receive the group treatment or be placed on a wait-list for monitoring purposes.

Motion sickness (MS) and postural control (PC) conditions are common complaints among those who passively travel. Many theories explaining a probable cause for MS have been proposed but the most prominent is the sensory conflict theory, stating that a mismatch between vestibular and visual signals causes MS. Few measurements have been made to understand and quantify the interplay between muscle activation, brain activity, and heart behavior during this condition.

The objective of the present work is to measure postural kinematics and power spectral variation from HD-EEG to assess changes in cortical activity during adaptation and habituation to postural perturbation. To evoke proprioceptive postural perturbation, vibratory stimulation at 85 Hz was applied to the calf muscles of 33 subjects over four 75-second stimulation periods. Stimulation was performed according to a pseudorandom binary sequence.

Article Synopsis
  • - Familial hypercholesterolemia (FH) is a genetic condition affecting 1 in 200 to 250 people globally, causing severe health risks due to lack of diagnosis and treatment, with only 10% of cases being identified.
  • - The World Health Organization designated FH as a public health priority in 1998 and issued 11 recommendations to improve its diagnosis, treatment, and awareness, but there has been minimal progress in their implementation over the last two decades.
  • - In 2018, the FH Foundation and World Heart Federation held meetings to update these recommendations by gathering input from international stakeholders across various income regions to address gaps and enhance FH management.

Objective: The objective of this study was to investigate how persons with acquired brain damage experienced their 1-week stay in an apartment fitted with electronic aids to daily living (EADL). The study focused on how the individuals adapted to this artificial environment in their performance of daily activities and how their occupational experiences influenced their view of the future.

Methods: The 11 participants were interviewed on the last day of their rehabilitation period in an EADL-equipped training apartment.

This article aims to clarify the psychoanalytic conceptualisation of the psychical, which includes a discussion of the relationship between consciousness and the unconscious. The unconscious is conceived of as being on the border between the so-called 'ego's conscious intending' and a rudimentary body-ego experiencing. Phenomenological ideas on the essence of consciousness are used in order to help delineate the crucial differences between consciousness and the unconscious.
