Bipolar Disorder Clinical Trial
Official title:
Multisite Repetitive Transcranial Magnetic Stimulation for Mood, Cognitive Impairment, Anhedonia and Disordered Sleep in Depressive Disorder
Depressed mood is the main symptom of depression, but other symptoms like cognitive impairment, anhedonia or sleep disorders may also contribute to patients suffering and are difficult to treat. rTMS is a relatively novel treatment option, whose therapeutic potential is still investigated and optimized. The aim of this study is to assess the effect of rTMS applied over two stimulation sites on cognitive impairment, anhedonia and sleep disorders in depression.

---|---|---|---|---|
Primary | Beck Depression Inventory 2 | Inventory consisting of 21 items measuring cognitive, affective, somatic, and vegetative symptoms of depression. Each item is scored from 0 to 3, with a higher score denoting more severe depression. Items are related to the criteria from the Diagnostic and Statistical Manual of Mental Disorders-IV. The minimum value of the total score is 0 and the maximum is 63 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. | |
Primary | Froward digit span | A measure of verbal short term and working memory. Participant is asked to repeat the random series of numbers, which become longer along with every correctly repeated one. Test is finished after participant failed to respond correctly on three occasions. The number of correctly repeated series determines the final score, which is an integer representing the length of the largest passed sequence. The scores range from 3 to 9 with higher scores denoting better outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. | |
Primary | Language part of Addenbrooke's Cognitive Examination | A test to identify cognitive impairment in dementia. In the language part, participant is asked to complete a set commands such as "place the paper on top of the pencil"; to write grammatically-complete sentences; to repeat several words and proverbs; to name the objects shown in drawings, and answer questions and to read several mispronounced words. The number of correctly completed tasks is scored. The minimum value of the total score is 0 and the maximum (of the language part) is 26 with higher scores meaning better outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. | |
Secondary | Dimensional Anhedonia Rating Scale | A 17-item scale that measures desire, motivation, effort and consummatory pleasure across hedonic domains. In each item, participant chooses one of four statements describing his attitude towards a given activity. The minimum value of the total score is 0 and the maximum is 68 with higher scores meaning better outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. | |
Secondary | Athens Insomnia Scale | An eight item scale. Each item is rated from 0 to 3 with higher scores representing more severe insomnia. Change from baseline score in the Athens Insomnia Scale to the measurement taken after finishing rTMS. The minimum value of the total score is 0 and the maximum is 24 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. | |
Secondary | Pittsburgh Sleep Quality Index | Pittsburgh Sleep Quality Index (PSQI) is a questionnaire to identify sleep disturbances. It consists of a combination of Likert-type and open-ended questions, which are later converted to scaled scores. Scores for each question range from 0 to 3. The minimum value of the total score is 0 and the maximum is 21 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. | |
Secondary | Epworth Sleepiness Scale | An eight-item scale. Each item refers to a situation such as driving a car or sitting quietly. The subject is asked to assess the chance of dosing in each situation, ranging from 0 (no chance) to 3 (dosing very likely). The minimum value of the total score is 0 and the maximum is 24 with higher scores meaning worse outcome. Change from the baseline to the measurement done after finishing intervention, to the measurement done two weeks after finishing intervention to the measurement done four weeks after finishing intervention. | Before intervention - four weeks after finishing intervention. |
