Borderline personality disorder in youth linked to altered brain activation during self-identity processing

Borderline personality disorder in youth linked to altered brain activation during self-identity processing

A new neuroimaging study suggests that adolescents with borderline personality disorder exhibit distinct patterns of brain activity when reflecting on their own identity. The findings indicate that these young patients show reduced activation in the dorsolateral prefrontal cortex, a region associated with cognitive control, compared to healthy peers. This research was published in Translational Psychiatry. Borderline personality disorder is a serious mental health condition. It is characterized by pervasive instability in moods, interpersonal relationships, self-image, and behavior. A central feature of this disorder is a disturbed sense of identity. Individuals often experience shifting goals, values, and vocational aspirations. This instability can manifest early in the course of the disorder. Many previous studies have investigated the biological roots of the condition. Most of research has focused on emotional dysregulation rather than identity disturbance. Existing functional imaging studies have typically involved adult patients. These adult participants often have a history of medication use or co-occurring psychiatric conditions. These factors can make it difficult to determine which brain abnormalities are specific to borderline personality disorder itself. To address …

Psychopathic female criminals exhibit unexpected patterns of emotional processing

Psychopathic female criminals exhibit unexpected patterns of emotional processing

Recent research indicates that incarcerated women with psychopathic traits exhibit unexpected patterns of emotional processing, particularly when viewing unpleasant images. A new study suggests that instead of displaying the fearlessness often associated with psychopathy, these women may engage in defensive emotional regulation strategies that result in a reduced sense of control. These findings were published in the journal Women & Criminal Justice. Psychopathy is a personality construct characterized by emotional deficits and antisocial behavior. It is historically studied through a male-centric lens. Researchers have established that the disorder manifests differently across genders. Men often display overt physical aggression. Women are more likely to utilize relational aggression, such as manipulation or emotional exploitation. This difference creates a gap in scientific understanding regarding how female offenders process emotions. The biological and social mechanisms driving these behaviors remain unclear. Understanding these nuances is essential for creating effective rehabilitation programs. Marina Pinheiro and her colleagues at the University of Minho in Portugal sought to address this disparity. They designed an investigation to measure how women in prison respond to …

US freezes visa processing from 75 countries over public assistance

US freezes visa processing from 75 countries over public assistance

U.S. Secretary of State Marco Rubio speaks during his end-of-year press conference at the State Department in Washington, D.C., U.S., Dec. 19, 2025. Kevin Mohatt | Reuters The State Department said Wednesday it will suspend the processing of immigrant visas for citizens of 75 countries whose nationals are deemed likely to require public assistance while living in the United States. The State Department, led by Secretary Marco Rubio, said it had instructed consular officers to halt immigrant visa applications from the countries affected in accordance with a broader order issued in November that tightened rules around potential immigrants who might become “public charges” in the U.S. The suspension, which will begin Jan. 21, will not apply to applicants seeking non-immigrant visas, or temporary tourist or business visas. “The Trump administration is bringing an end to the abuse of America’s immigration system by those who would extract wealth from the American people,” the department said in a statement. “Immigrant visa processing from these 75 countries will be paused while the State Department reassess immigration processing procedures to prevent the entry of foreign nationals who would take welfare and public benefits.” The statement …

Fragmented sleep predicts slower mental processing speed the next day in older adults

Fragmented sleep predicts slower mental processing speed the next day in older adults

New research published in the journal Sleep Health has found that sleep fragmentation, which refers to the amount of time spent awake in bed after initially falling asleep, is linked to slower mental processing speeds the next day in older adults. The findings suggest that the continuity of sleep may be more relevant to daily cognitive functioning in later life than the total number of hours slept. Sleep is widely recognized as a fundamental pillar of physical health, yet its specific relationship to cognitive maintenance in older age remains a subject of scientific inquiry. Much of the existing data regarding sleep and aging relies on information collected at a single point in time, often asking participants to recall their general sleep habits over weeks or months. This approach provides a broad overview but often misses the dynamic, day-to-day variations in rest and mental acuity that define daily living. The authors of the current study sought to fill this gap by observing how fluctuations in sleep quality on a specific night relate to cognitive performance on …

Single session of weightlifting improves executive function and processing speed

Single session of weightlifting improves executive function and processing speed

A new study found that processing speed regarding inhibitory control (the ability to suppress automatic or impulsive responses) and working memory improved in a group of participants after moderate-intensity resistance exercises compared to a group that was resting and watching a video during that time. Blood lactate levels and systolic blood pressure also increased after exercises. The paper was published in Psychophysiology. Resistance exercises are physical activities that make muscles work against an external force, such as weights, resistance bands, or one’s own body weight. They are designed to increase muscle strength by challenging the muscles to contract against this resistance. Common forms include weightlifting, push-ups, squats, and exercises using machines in a gym. These exercises trigger muscle fibers to adapt and grow stronger over time. Resistance training can also help improve bone density, which is especially important for preventing osteoporosis. It boosts metabolism because stronger muscles burn more calories even at rest. Such exercises are valuable for improving balance and coordination, particularly in older adults. They also reduce the risk of injuries by strengthening …
