“…Whether TMS improves insomnia symptoms or causes the decrease of EEG abnormalities making better sleep, is a question that must be answered by new researchers. A positive relation between the severity of insomnia and the frequency of EEG abnormalities has previously been reported [1].…”

“…Insomnia has multiple subtypes and multiple etiological factors. Regarding idiopathic insomnia, one of the subtypes, we have recently reported that nearly 50% of the patients diagnosed with this sleep disorder, actually show EEG abnormalities characterized by sharp-wave activity with phase inversion, spikes and sharp-wave activity in the left frontal and front-central area [1].…”

Insomnia is one of the most frequently observed sleep disorders, affecting nearly 10% of the general population. It has multiple etiological factors. Recently, it has been reported that EEG abnormalities are associated with insomnia in patients previously diagnosed as idiopathic insomniacs. In addition, transcranial magnetic stimulation (TMS) has shown to be effective in the treatment of disorders characterized by neural hyper-excitability. Method: In the present study, patients with insomnia and EEG abnormalities were submitted to slow repetitive trans-cranial magnetic stimulation, for 15 minutes daily during 10 days. Polysomnographic recordings were performed before and after TMS. Results: The results indicate that the presence of EEG abnormalities significantly decreased after TMS. In addition, most of the sleep parameters showed significant improvement. Conclusions: These data support the notion that TMS is a reliable therapeutic tool for patients affected with abnormalities linked to neuronal hyper-excitability.
