The effect of QEEG- guided neurofeedback treatment in decreasing of OCD symptoms

The efficacy of biofeedback approaches for obsessive-compulsive and related disorders: A systematic review and meta-analysis

“…The other works were performed in Turkey (Sürmeli and Ertem, 2011), Iran (Barzegary et al, 2011), Canada (Mills and Solyom, 1974), China (Deng et al, 2014), and USA (Hammond, 2004(Hammond, , 2003LeVine, 1983;Scheinost et al, 2014). Three works were randomized controlled trials (Barzegary et al, 2011;Deng et al, 2014;Koprivová et al, 2013). From these 3 trials, 1 was a doubleblind study (Koprivová et al, 2013) and 1 was a single-blind study (Deng et al, 2014).…”

“…Two studies combined the neurofeedback effects with CBT (Koprivová et al, 2013) or medication and CBT (Deng et al, 2014). For control, the 3 trials mentioned above used a waiting list group and medication group (Barzegary et al, 2011), a medication and CBT combined group (Deng et al, 2014), or a sham biofeedback and CBT combined group (Koprivová et al, 2013). The biofeedback intervention had an average duration of 31.8 (21.8) sessions (one study with missing information (LeVine, 1983)).…”

“…The biofeedback intervention had an average duration of 31.8 (21.8) sessions (one study with missing information (LeVine, 1983)). The brain regions target during the neurofeedback intervention were the anterior insula (Buyukturkoglu et al, 2015) and orbitofrontal cortex/Brodmann area 10 (Scheinost et al, 2014), but most of the studies used an individualized approach targeting subject-specific brain regions with abnormal activation (Barzegary et al, 2011;Hammond, 2003Hammond, , 2004Koprivová et al, 2013;Sürmeli and Ertem, 2011). The studies selected for the systematic review did not include overlap data from the same participant.…”

Neurofeedback and its possible relevance for the treatment of Tourette syndrome

“…Numerous studies have demonstrated the feasibility and effectiveness of NF in the treatment of a variety of neuropsychiatric conditions such as autism, anxiety, affective and personality disorders, PTSD, alcoholism, drug abuse and OCD (Barzegary et al, 2011;Coben and Myers, 2010;Heinrich et al, 2007;Surmeli and Ertem, 2011). Closely related to its application in the treatment of ADHD and OCD, NF has further been recognized as a potential therapy tool in the context of Gilles-de-la-Tourette syndrome (GTS) (Messerotti Benvenuti et al, 2011;Rothenberger and Gevensleben, 2013;Tansey, 1986), which is frequently accompanied by symptoms or comorbid diagnoses of ADHD and OCD.…”

“…As a new non-invasive brain stimulating method, NF (Barzegary et al, 2011;Hammond, 2007) might offer a more attractive alternative notably for younger patients but also in general for all patients who do not comply with or respond to conventional pharmacological and behavioral interventions (Verdellen et al, 2011). The assumed potential of NF for treating tics is rooted in its ability to directly target the underlying neurophysiology (Monastra et al, 2002) of fronto-striatal networks (Watkins et al, 2005).…”
