ABSTRACT: 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.
