The Bhagavad Gita and Contemporary Psychotherapies

The Bhagavad Gita is based on a discourse between Lord Krishna and Arjuna at the inception of the Kurukshetra war and elucidates many psychotherapeutic principles. In this article, we discuss some of the parallels between the Gita and contemporary psychotherapies. We initially discuss similarities between psychodynamic theories of drives and psychic structures, and the concept of three gunas. Arjuna under duress exhibits elements of distorted thinking. Lord Krishna helps remedy this through a process akin to Cognitive Behavioral Therapy (CBT). We ascertain the analogies between the principles of Gita and CBT, grief emancipation, role transition, self-esteem, and motivation enhancement, as well as interpersonal and supportive psychotherapies. We advocate the pragmatic application of age old wisdom of the Gita to enhance the efficacy of psychotherapeutic interventions for patients from Indian subcontinent and to add value to the art of western psychotherapies.

Clinical utility of the risperidone formulations in the management of schizophrenia

Risperidone is one of the early second-generation antipsychotics that came into the limelight in the early 1990s. Both the oral and long-acting injectable formulations have been subject to numerous studies to assess their safety, efficacy, and tolerability. Risperidone is currently one of the most widely prescribed antipsychotic medications, used for both acute and long-term maintenance in schizophrenia. Risperidone has better efficacy in the treatment of psychotic symptoms than placebo and possibly many first-generation antipsychotics. Risperidone fares better than placebo and first-generation antipsychotics in the treatment of negative symptoms. Risperidone’s long acting injectable preparation has been well tolerated and is often useful in patients with medication nonadherence. Risperidone has a higher risk of hyperprolactinemia comparable to first-generation antipsychotics (FGAs) but fares better than many second-generation antipsychotics with regards to metabolic side effects. In this article, we briefly review the recent literature exploring the role of risperidone formulations in schizophrenia, discuss clinical usage, and highlight the controversies and challenges associated with its use.

App Use in Psychiatric Education: A Medical Student Survey

ObjectiveThe objective of the study is to understand and appraise app use by medical students during their clerkships.MethodsFollowing Creighton University IRB approval, a voluntary and anonymous paper-based, 15-question survey was distributed to third-year medical students. Data were analyzed using Microsoft Excel.ResultsOf 112 medical students available, 76.7% (86) participated in the survey. All participants owned a smartphone or tablet with 84.9% using Apple iOS, followed by 12.8% using Android platform. Students reported using the fewest number of apps during surgery, psychiatry, and obstetrics and gynecology clerkships. The largest number of apps were used during the internal medicine rotation (70.3%). The three most popular apps were Epocrates, UpToDate, and UWorld. The most common uses for these apps were as references during the clerkship, followed by improving knowledge, and test taking. Perceived major benefits included accessibility (96% of student respondents) and interactivity (39.5%). Common apps used during the psychiatry clerkship included UpToDate (71%), Epocrates (51%), and Medscape (43%). Despite less frequent app use during their psychiatry clerkship, 90% felt there was a utility for educational apps in psychiatric education.ConclusionsConsistent with the previous literature on medical students preferring educational apps, students suggest developers focus on question bank-type apps, followed by clinical support-focused and self-directed case-based learning apps for psychiatry clerkship learning. Educators should factor these modes of educational delivery into future educational app development. This survey shows a high degree of smartphone and tablet use among medical students, and they attest to mobile phone app utility in psychiatric education.

Biological markers in schizophrenia: An update.

Biological markers are quantitative measures that allow clinicians to diagnose and assess the disease process, monitor response to treatment and may, to some extent, assist with prognostic assessments (1). Biological markers can modify the way clinicians approach, treat and care for patients. This has significant diagnostic and treatment-related implications, especially for chronic disabling disorders with complex etiopathogenesis, such as schizophrenia. Years of research have yielded a variety of relatively consistent findings in different domains including neuroanatomy, functional and molecular neuroimaging, neurophysiology, genetics and biochemistry. These attributes can complement clinical findings with improved diagnostic validity, and to some extent, assist the clinician in early initiation of efficacious treatment and predicting prognosis. On the contrary, many of these potential biological markers may require expensive testing and enhanced technological expertise. Considering the issues with sensitivity and specificity and an overlap with other neuropsychiatric disorders, their role in routine clinical care continues to be ambiguous.

Youth with substance abuse histories exhibit dysfunctional representation of expected value during a passive avoidance task

Individuals with substance abuse (SA) histories show impairment in the computations necessary for decision-making, including expected value (EV) and prediction error (PE). Neuroimaging findings, however, have been inconsistent. Sixteen youth with (SApositive) and 29 youth without (SAnegative) substance abuse histories completed a passive avoidance task while undergoing functional MRI. The groups did not significantly differ on age, gender composition or IQ. Behavioral results indicated that SApositive youth showed significantly less learning than SAnegative youth over the task. SApositive youth show problems representing EV information when attempting to avoid sub-optimal choices in bilateral inferior frontal gyrus and striatum. Furthermore, SApositive youth showed a significantly increased differential response to reward versus punishment feedback modulated by PE in posterior cingulate cortex relative to SAnegative youth. Disrupted decision-making is likely to exacerbate SA as a failure to represent EV during the avoidance of sub-optimal choices is likely to increase the likelihood of SA. With respect to the representation of PE, future work will be needed to clarify the impact of different substances on the neural systems underpinning PE representation. Moreover, interaction of age/development and substance abuse on PE signaling will need to be explored.
