Utilization of MRS to Identify Neurochemical Abnormalities in Patients With Bipolar Disorder

(PSYCHIATRIC TIMES) - Magnetic resonance spectroscopy (MRS) is a useful, noninvasive method of examining alterations in brain neurochemistry that might be associated with the development of bipolar disorder (BD) and the effects of treatment (Soares et al., 1996). It uses the same technology as magnetic resonance imaging and provides a frequency signal intensity spectrum of multiple peaks that reflect the metabolite levels of a localized region in the brain. Magnetic resonance spectroscopy data… Continue

Brain Imaging Data of ADHD

(PSYCHIATRIC TIMES) - In the United States, approximately 2% to 6% of school-age children are diagnosed with attention-deficit/hyperactivity disorder. Data show that stimulant medication is the most consistently successful form of treatment in ADHD, with psychostimulants such as dextroamphetamine (Adderall, Dexedrine) and methylphenidate (Ritalin) exerting therapeutic effects via modulation of the noradrenergic and dopaminergic systems. In the United States, methylphenidate is used to treat… Continue
