Brief Summary

Psychomotor slowing may occur in major psychiatric disorders, such as major depressive disorders or schizophrenia spectrum disorders. It refers to slowing of fine motor skills, motor planning and gross motor behavior. In major depression and schizophrenia, psychomotor slowing is associated with alterations of premotor cortex, dorsolateral prefrontal cortex and basal ganglia. This randomized, sham-controlled, prospective trial will test, whether 15 sessions of repetitive transcranial magnetic stimulation (rTMS) may ameliorate psychomotor slowing in schizophrenia or major depression.

Study Arms (4)

DLPFC facilitatory

ACTIVE COMPARATOR

repetitive transcranial magnetic stimulation (rTMS) of 15 Hz over left DLPFC usually effective in depression treatment, probably no specific effect on psychomotor slowing

Other: DLPFC facilitatory

preSMA/SMA inhibitory

EXPERIMENTAL

repetitive transcranial magnetic stimulation (rTMS) of 1 Hz over preSMA/SMA should inhibit overactive premotor cortices

Other: SMA inhibitory

preSMA/SMA facilitatory

EXPERIMENTAL

intermittend theta burst stimulation (iTBS) over preSMA/SMA should facilitate neural activity within premotor cortices

Other: SMA facilitatory

sham TMS

SHAM COMPARATOR

sham rTMS with a placebo coil over occipital cortex should have no effect at all (no transcranial magnetic stimulation, only sound)

Other: sham TMS

Interventions

15 Hz stimulation of left dorsolateral prefrontal cortex (DLPFC)(15 sessions/3weeks, 1500 stimuli per session, stimulation intensity 100% of the individual active motor threshold; in total 22500 stimuli

Also known as: rTMS facilitatory DLPFC
DLPFC facilitatory

1 Hz stimulation of preSMA/SMA (15 sessions/3weeks, 1500 stimuli per session, stimulation intensity 100% of the individual active motor threshold; in total 22500 stimuli

Also known as: rTMS inhibitory SMA
preSMA/SMA inhibitory

Three pulses of stimulation at 50 Hz of preSMA/SMA, repeated every 200 ms. 2 s trains are repeated every 10 s for a total of 190 s (600 pulses, 200 seconds). intensity 80% of individual active motor threshold; in total 9000 stimuli

Also known as: iTBS facilitatory SMA
preSMA/SMA facilitatory

Determination of active motor threshold and subsequent stimulation with the placebo coil, with the same sounds but without effects. 15 sessions in three weeks, duration of 20 mins per session

sham TMS
