Alivio do transtorno de estresse pós-traumático (PTSD) com TMS
Novas pesquisas sugerem que a estimulação do repetitiva de determinadas regiões do cérebro com ímãs pode ajudar aliviar os sintomas do transtorno de estresse pós-traumático (PTSD), uma condição psiquiátrica debilitante que possa ocorrer após a exposição aos eventos traumatizantes, tais como o combate das forças armadas ou um assalto pessoal violento. Uma região do cérebro chamado o cortex prefrontal tem "um papel importante em mediar respostas às situações estressoras," disseram Dra. Hagit Cohen e colegas da universidade de Ben-Gurion do Negev, Beer Sheva, Israel em nota ao American Journal of Psychiatry.
Em um estudo mais adiantado, dois pacientes com PTSD experimentaram melhorias após o tratamento com a estimulação magnética. No estudo atual, o grupo avaliou os efeitos terapêuticos da terapia magnética baixa e de alta freqüência em comparação à terapia simulada em 24 pacientes com PTSD. A terapia de alta freqüência teve efeitos benéficos maiores do que a terapia de baixa freqüência ou placebo. Os pacientes no grupo de alta freqüência mostraram também reduções mais pronunciadas na ansiedade do que aqueles do grupo de baixa freqüência. Diversos pacientes em ambos os grupos da terapia magnética relataram melhorias no sono após o tratamento.
Baseado neste pequeno estudo preliminar, experimentações da terapia magnética de alta freqüência "pode ser um caminho promissor para pesquisas adicionais em pacientes com PTSD".

New research suggests that repeat stimulation of certain brain regions with magnets can help
alleviate the symptoms of post-traumatic stress disorder (PTSD), a debilitating psychiatric condition that can occur after exposure to life-threatening events, such as military combat or violent personal assault.
A region of the brain called the prefrontal cortex has an “important role in mediating responses to stressful situations,” Dr. Hagit Cohen and colleagues from Ben-Gurion University of the Negev in Beer Sheva, Israel note in the American Journal of Psychiatry.
In an earlier study, two patients with PTSD experienced improvements after treatment with magnetic stimulation, they add.
In the current study, the group evaluated the therapeutic effects of low- and high-frequency magnetic therapy as compared with fake therapy in 24 patients with PTSD.
High-frequency therapy had greater beneficial effects than low-frequency or fake therapy. Patients in the high frequency group also showed far greater reductions in anxiety than did those in the low-frequency group. Several patients in both magnetic therapy groups reported improvements in sleep after being treated.
Based on this small, preliminary study, trials of high-frequency magnetic therapy “may be a promising avenue for further research with PTSD patients,” the authors conclude.
Repeat stimulation of brain regions with magnets helps post-traumatic stress disorder
Repeat stimulation of brain regions with magnets helps post-traumatic stress disorder, this is according to new research carried out in Israel .
Post-traumatic stress disorder (PTSD) is a psychiatric condition. It is very debilitating. People who have been exposed to dangerous (life threatening) situations can get PTSD.

Repetitive Transcranial Magnetic Stimulation of the Right
Dorsolateral Prefrontal Cortex in Posttraumatic Stress Disorder:
A Double-Blind, Placebo-Controlled Study

Kouperman, M.D., Regina Moisa, B.N.S., and Nimrod Grisaru, M.D.
OBJECTIVE: The efficacy of repetitive transcranial magnetic
stimulation (rTMS) of the right prefrontal cortex was studied in
patients with posttraumatic stress disorder (PTSD) under
double-blind, placebo-controlled conditions.
METHOD: Twenty-four patients with PTSD were randomly assigned to
receive rTMS at low frequency (1 Hz) or high frequency (10 Hz) or
sham rTMS in a double-blind design. Treatment was administered in
10 daily sessions over 2 weeks. Severity of PTSD, depression, and
anxiety were blindly assessed before, during, and after
completion of the treatment protocol.
RESULTS: The 10 daily treatments of 10-Hz rTMS at 80% motor
threshold over the right dorsolateral prefrontal cortex had
therapeutic effects on PTSD patients. PTSD core symptoms
(reexperiencing, avoidance) markedly improved with this
treatment. Moreover, high-frequency rTMS over the right
dorsolateral prefrontal cortex alleviated anxiety symptoms in
PTSD patients. CONCLUSIONS: This double-blind, controlled trial
suggests that in PTSD patients, 10 daily sessions of right
dorsolateral prefrontal rTMS at a frequency of 10 Hz have greater
therapeutic effects than slow-frequency or sham stimulation.
