Deep brain stimulation for psychiatric disorders and behavioral/cognitive-related indications: Review of the literature and implications for treatment.

While pharmacological and/or behavioral treatments are effective in managing symptoms for many patients with psychiatric diagnoses and disorders with behavioral/cognitive manifestations, a subset of individuals are treatment-refractory, unable to achieve appreciable benefit or symptom relief from traditional methods. In recent years, neuromodulation has gained momentum as an adjunctive treatment for improving outcomes in patients who are treatment-refractory. One form of neuromodulation, deep brain stimulation (DBS), has been investigated for the treatment of various psychiatric disorders and behavioral/cognitive symptoms.

The accuracy of fitness watches for the measurement of heart rate and energy expenditure during moderate intensity exercise.

Background: As new technology emerges and updated fitness watches are released to the market, it is important to examine their accuracy. The aim of the current study was to examine the accuracy of three commercially available activity trackers in assessing heart rate (HR) and energy expenditure (EE) during moderate intensity exercise.

Methods: Twenty healthy participants (Age: 20.
