Traumatic brain injury (TBI) occurs when a blow or jolt to the head or a penetrating injury results in damage to the brain. It is the most frequent cause of hospitalization in young people with a higher prevalence in men. TBI is the leading cause of disability and mortality between the ages 1 and 45. TBI can be caused either by the direct result of trauma or due to a complication of the primary injury. The most common etiological factors for TBI are falls, road traffic accidents, violent physical assaults, and injuries associated with athletic activities. Following TBI, significant neurologic complications may occur which include seizures, dementia, Alzheimer's disease, and cranial nerve injuries. In addition, people may suffer from various psychiatric complications such as depression, posttraumatic stress disorder, generalized anxiety disorder, obsessive-compulsive disorder, and other cognitive and behavioral sequel that might significantly increase the comorbidity of the victims. Considering all of the above complications, TBI is one of the significant public health burdens. Literature has shown that only about 25% of people achieve long-term functional independence following TBI. In this paper, we focused not only on the epidemiology but also the etiology, complications following TBI and understanding their underlying pathogenesis. Further, we focused on analyzing the options to improve the treatment and rehabilitation following TBI in future.

Depression is the most frequently seen neuropsychiatric manifestation in stroke patients. It hampers the ability to undergo therapy and impairs their functional outcome. Depression also increases the risk of suicide in stroke patients, therefore, increasing mortality. The etiology of post-stroke depression (PSD) is complex and reported to be multi-factorial in origin. It also depends on the size and location of the infarct. In addition, family history or prior history of depressive disorders makes them prone to be affected with depression following a stroke. In this article, we will mention various aspects of PSD, as well as the prevalence and the different screening assessment tools used in literature studies. Although there are many available testing tools, little consistency was seen in them being valid or reliable. We will also discuss the pathophysiology of depression in stroke patients with various available options for managing the condition. We will briefly review the use of alternative treatment such as Electroconvulsive therapy (ECT) and Transcranial Magnetic Stimulation (TMS) as well. However, we need further evidence-based research exploring the screening tool; i.e. universally acceptable for PSD and implementing an effective, non-invasive treatment modality impacting the prognosis. Also, we require further investigations to identify the role of antidepressants in the recovery of stroke patients.

Based on the literature studies, there is variability in data reported about PSD prevalence. These differences are usually due to the variations in criteria used to diagnose PSD and the difference in age of patients studied. The higher prevalence was seen in hospital-based settings rather than community-based settings [14].While several clinicians use DSM-III and DSM-IV criteria to reach the diagnosis of PSD, some use a different kind of scales or questionnaires. Also, different clin...

AimTo assess the relative efficacies of clozapine plus Electroconvulsive Therapy (ECT) compared against non-clozapine typical and atypical antipsychotics plus ECT for the treatment of “Treatment Resistant Schizophrenia” (TRS). Primarily to assess if clozapine delivers a significant improvement over other antipsychotics when combined with ECT.DesignMajor electronic databases were searched between 1990 and March 2017 for trials measuring the effects of either clozapine augmented ECT, other antipsychotic-augmented ECT, or both. After the systematic review of the data, a random-effects meta-analysis was conducted measuring the relative effect sizes of the different treatment regimens.Subjects1179 patients in 23 studies reporting the usage of ECT augmentation with antipsychotics. A total of 95 patients were tested with clozapine, and ECT (9 studies) and 1084 patients were tested with non-clozapine antipsychotics (14 studies) such as flupenthixol, chlorpromazine, risperidone, sulpiride, olanzapine, and loxapine with concurrent ECT treatment considered for systematic review. Of these, 13 studies reported pre and post-treatment scores were included in the meta-analysis.Main outcome measuresThe main outcome measure was the presence and degree of both positive and negative psychotic symptoms, as measured by either of two standardized clinician administered tests, the Brief Psychiatric Rating Scale (BPRS), and the Positive and Negative Symptom Scale (PANSS).ResultsThe comparison of the different antipsychotics established the supremacy of ECT-augmented clozapine treatment against other typical and atypical antipsychotics. The Forest Plot revealed that the overall standard mean difference was 0.891 for non-clozapine studies and 1.504 for clozapine studies, at a 95% interval. Furthermore, the heterogeneity plots showed that while clozapine studies showed no significant heterogeneity, non-clozapine studies showed an I2 statistic value at 42.19%, suggesting moderate heterogeneity. Lastly, publication bias showed asymmetrical plots and significant values of Kendal's tau and Egger's rank test.ConclusionECT augmentation technique was found to be effective in the reduction of psychometric scale scores, and the resulting improvement was significant. Clozapine maintained its stance as the most effective treatment for Treatment-Resistant Schizophrenia, followed by flupenthixol.

Journal of Psychiatry AbstractSuicide is the tenth leading cause of death in the United States. According to research in 2016, the suicide rate has increased substantially both in the United States and worldwide. Most people who commit suicide are found to suffer from psychiatric illnesses like depression, schizophrenia, anxiety, bipolar disorder, alcoholism, and post traumatic stress disorder (PTSD). In the past several studies are conducted to examine which drugs decrease suicidal ideation in mentally ill patients. Selective serotonin reuptake inhibitors (SSRIs) like Prozac (fluoxetine) are believed to decrease suicidal intentions in patients with depressive disorders. Similarly, lithium and clozapine are effective in reducing suicidality in patients with bipolar depression and schizophrenia, respectively. Although these drugs have a demonstrated efficacy to reduce suicidality long-term, there is limited evidence that these drugs have the same effect during the acute phase of illness. Most psychotropic medications take a few weeks to work; unfortunately, some patients require sufficiently more time to stabilize their symptoms. Because time is a crucial factor when dealing with suicidal patients, we express our viewpoint regarding the use of ketamine, which may, within hours or days help patients with suicidal ideation.
