Cognitive dysfunction and anhedonia, the reduced ability to experience pleasure, are commonly comorbid symptoms that are persistent following successful resolution of negative affect in major depressive disorder (MDD). Little is known about whether they share common etiology. In the present study, the relationship between ventrolateral prefrontal cortex (VLPFC) activity, cognitive dysfunction (i.e., executive dysfunction), and positive emotionality was investigated in conjunction with mu-opioid neurotransmission in a sample of 39 MDD patients...

The authors investigated retrospective timing in participants with Korsakoff's syndrome. Patients were assessed on four retrospective tasks on which they were instructed to read three-digit numbers aloud (15 seconds), fill connected squares (30 seconds), decide whether words were abstract or concrete (45 seconds), or read aloud a text about mushroom picking (60 seconds). Participants were not aware of the task's timing until the end of the tasks, when they were asked to estimate the elapsed time. Results revealed an underestimation of the elapsed time in Korsakoff participants, suggesting that time is perceived to pass quickly for these participants...

Delusions are beliefs that remain fixed despite evidence that they are incorrect. Although the precise neural mechanism of delusional belief remains to be elucidated, there is a predominance of right-hemisphere lesions among patients with delusional syndromes accompanied by structural pathology, suggesting that right-hemisphere lesions, or networks with key nodes in the right hemisphere, may be playing a role. The authors discuss the potential theoretical basis and empiric support for a specific right-hemisphere role in delusion production, drawing on its roles in pragmatic communication; perceptual integration; attentional surveillance and anomaly/novelty detection; and belief updating...

The misidentification of one's own limb (LM) after right hemisphere stroke is a striking phenomenon that is incompletely understood. The authors prospectively studied the natural history and anatomy of LM in 36 patients with hyperacute right middle cerebral artery infarct. Unlike in previous studies, rapid clinical assessment was prioritized. The authors found LM to be common and transient, involving 61% at onset, evolving to 15% at 1 week. Voxel-based lesion-symptom mapping found supramarginal gyrus (SMG) damage associated with LM...

The Clock-Drawing Test (CDT) is a brief, relatively time-efficient, easy to administer at bedside, and well-proven cognitive screening test that assesses a broad range of cognitive abilities in stroke, delirium, and dementia. However, challenges of comprehensive therapeutic outcome evaluations in schizophrenia can also be potentially overcome using CDT. The authors aimed to measure the therapeutic outcome using CDT in 101 schizophrenia patients, irrespective of their diagnostic subtypes. A repeated measures analysis of variance found that improvements on CDT and the Positive and Negative Syndrome Scale were closely correlated, reflecting critical information about therapeutic response measures in schizophrenia...

Timely treatment of depression and behavioral dysfunction after moderate-to-severe traumatic brain injury (TBI) could improve health, function, and quality of life. The authors hypothesized that 6-month depression would be the stronger contributor to later depression and behavioral dysfunction in a sample of 88 adults with moderate-to-severe TBI. A structural equation modeling cross-lagged panel analysis, adjusting for all 6-month predictors, revealed that 6-month depression had a stronger relationship to 12-month depression (βstand=0...

The authors examined 28 dementia inpatients receiving treatment as usual. Beginning-to-end differences in neuropsychiatric symptoms and actigraphic sleep patterns were measured. Using a mixed-model, the authors regressed neuropsychiatric symptoms on average sleep minutes (between-subjects effect) and each night's deviation from average (within-subject effect). Sleep did not significantly differ from beginning to end of participation, whereas neuropsychiatric symptoms did. Average sleep minutes predicted average neuropsychiatric symptoms (p=0...

Serious mental illness (SMI) is disabling, and current interventions are ineffective for many. This exploratory study sought to demonstrate the feasibility of applying topological data analysis (TDA) to resting-state functional connectivity data obtained from a heterogeneous sample of 235 adult inpatients to identify a biomarker of treatment response. TDA identified two groups based on connectivity between the prefrontal cortex and striatal regions: patients admitted with greater functional connectivity between these regions evidenced less improvement from admission to discharge than patients with lesser connectivity between them...

The C9orf72 mutation was identified as the most frequent genetic cause of frontotemporal dementia (FTD). In light of multiple reports of predominant psychiatric presentations of FTD secondary to C9orf72 mutation, the American Neuropsychiatric Association Committee on Research reviewed all studies on psychiatric aspects of this mutation to identify clinically relevant features for diagnosis. The most common psychiatric presentation is psychosis (21%-56%), with delusions, and/or multimodal hallucinations. Other presentations include late-onset mania and depression with cognitive impairment or catatonia...

Although major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are prevalent after traumatic brain injury (TBI), little is known about which patients are at risk for developing them. The authors systematically reviewed the literature on predictors and multivariable models for MDD and PTSD after TBI. The authors included 26 observational studies. MDD was associated with female gender, preinjury depression, postinjury unemployment, and lower brain volume, whereas PTSD was related to shorter posttraumatic amnesia, memory of the traumatic event, and early posttraumatic symptoms...

Patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis may remain undiagnosed and untreated with immunotherapy. To investigate specific features and responses to immunotherapy of atypical anti-NMDAR antibody positivity patients, the authors reviewed and evaluated previous case reports/series including patients without seizure, involuntary movement, hypoventilation, or tumor. Of 22 patients identified, 21 responded to immunotherapy. Two patients had neurological/motor symptoms with few/no psychiatric/cognitive symptoms, and eight had both...

Drowsiness may be defined as the progressive loss of cortical processing efficiency that occurs with time passing while awake. This loss of cortical processing efficiency is reflected in focal changes to the electroencephalogram, including islands of increased delta power concurrent with drop-offs in neuronal activity (i.e., focal cortical inactivity). The authors hypothesized that these focal changes are evidenced at individual electrodes by combination of increased instantaneous amplitude in delta band and decreased instantaneous frequency in theta-alpha band, permitting their categorization as "active" and "inactive...

This study randomly sampled post-9/11 military veterans and reports on causes, predictors, and frequency of traumatic brain injury (TBI) (N=1,388). A total of 17.3% met criteria for TBI during military service, with about one-half reporting multiple head injuries, which were related to higher rates of posttraumatic stress disorder, depression, back pain, and suicidal ideation. The most common mechanisms of TBI included blasts (33.1%), objects hitting head (31.7%), and fall (13.5%). TBI was associated with enlisted rank, male gender, high combat exposure, and sustaining TBI prior to military service...

Non-invasive brain stimulation (NIBS) might be a new approach to treat substance use disorders (SUD). A systematic review and critical analysis was performed to identify potential therapeutic effects of NIBS on addictions. A search of the Medline database was conducted for randomized sham-controlled trials using NIBS in the field of addiction and published until August 2016. Twenty-six studies in various SUD met the inclusion criteria. Converging evidence indicates that NIBS might be a promising mean to treat patients with alcohol and tobacco use disorders, by acting on craving reduction and other mechanisms such as improvement in cognitive dysfunctions...

Mario F Mendez
Differences in political ideology are a major source of human disagreement and conflict. There is increasing evidence that neurobiological mechanisms mediate individual differences in political ideology through effects on a conservative-liberal axis. This review summarizes personality, evolutionary and genetic, cognitive, neuroimaging, and neurological studies of conservatism-liberalism and discusses how they might affect political ideology. What emerges from this highly variable literature is evidence for a normal right-sided "conservative-complex" involving structures sensitive to negativity bias, threat, disgust, and avoidance...
