Eksperimentel: Aktiv tDCS
Denne gruppe vil modtage daglig aktiv stimulation (2 mA) til venstre dorsolaterale præfrontale cortex i 4 uger gennem en hjemmebaseret tDCS-enhed i fjernovervågede 30-minutters sessioner.
|
2 mA anodal stimulation vil blive påført den venstre præfrontale cortex over F3-elektroden baseret på det internationale 10-10 EEG-system.
|
|
Sham-komparator: Sham tDCS
Denne gruppe vil modtage daglig simuleret stimulation til venstre dorsolaterale præfrontale cortex i 4 uger gennem en hjemmebaseret tDCS-enhed i fjernovervågede 30-minutters sessioner.

|
Inhibitory Control
Tidsramme: Baseline
|
Performance during the incongruent trials of the Eriksen Flanker Task were assessed at baseline (before the beginning of the 4-week home tDCS intervention).
The performance is quantified as the ratio of correct responses to all responses.
For example, a score of 0.70 indicates that the participant responded to 70% of the trials correctly.

Inhibitory Control
Tidsramme: Posttreatment (1 month follow-up)

Performance during the incongruent trials of the Eriksen Flanker Task were assessed approximately approximately 4-weeks after baseline.

For example, a score of 0.70 indicates that the participant responded to 70% of the trials correctly.

EEG P300 Event-related Potential
Tidsramme: Baseline
|
EEG P300 amplitudes time-locked to the incongruent trials of the Eriksen Flanker Task were assessed at baseline (before the beginning of the 4-week home tDCS intervention).
EEG event-related potential amplitudes (measured in microvolts, µV) were normalized across EEG channels using a scaling procedure, in which each channel was rescaled to reduce variability in signal magnitude among electrodes while preserving temporal and spectral characteristics.
While larger P300 amplitudes are typically associated with better cognitive outcomes, this can vary among study populations.

Cognitive Flexibility
Tidsramme: Baseline
|
Performance on the NIH Toolbox Dimensional Change Card Sort Test, a computerized measure of executive function assessing cognitive flexibility, attention, and set-shifting.
Participants match target stimuli based on changing rules (e.g., color or shape).
Scores are reported as fully corrected (for age, gender, race/ethnicity, and education) T-scores (mean = 50, SD = 10), with higher scores indicating better cognitive flexibility and executive control.

Working Memory
Tidsramme: Baseline
|
Performance on the NIH Toolbox List Sorting Working Memory Test, which assesses working memory capacity through sequencing and recall of visually and verbally presented stimuli in size order.
The task requires temporary storage and manipulation of information across increasing list lengths.
Scores are reported as fully corrected (for age, gender, race/ethnicity, and education) T-scores (mean = 50, SD = 10), with higher scores indicating better working memory performance.

Episodic Memory
Tidsramme: Baseline
|
Performance on the NIH Toolbox Picture Sequence Memory Test, a measure of episodic memory in which participants reproduce the order of a sequence of visually presented pictures.
The task assesses the ability to encode, store, and retrieve sequential information.
Scores are reported as fully corrected (for age, gender, race/ethnicity, and education) T-scores (mean = 50, SD = 10), with higher scores indicating better episodic memory function.
