This discovery may offer new hope for understanding the biological basis of schizophrenia and other neurodevelopmental condi...
Compulsive behaviours are common across many mental health conditions, where people repeat actions despite negative consequences. New research in rats suggests that triggering inflammation in the striatum may shift behaviour toward more deliberate decision-making, rather than habit.
A new study suggests that midlife depression is driven by a small cluster of specific symptoms, rather than depression overall. The six symptoms are loss of self-confidence, difficulty coping with problems, and poor concentration, which can lead to reduced social engagement and decreased cognitive reserve.
A study from the University of East Anglia explores how our brains remember past events and how those memories can change over time. Memories are made up of different parts and can become less accurate or include new information as they are retrieved.
Researchers found that recalling memories is facilitated when breathing cues are presented during inhalation, with actual memory retrieval happening during exhalation. The study suggests that respiration acts as a natural pacemaker for memory processes, highlighting the close interaction between the brain and body.
A new study reveals limited data on cognition in individuals with comorbid personality disorder and schizophrenia, leading to unfavourable outcomes. The researchers emphasize the need for further investigation into adapting treatments to support functional recovery.

Practicing healthy sleep hygiene behaviors can help break the stress-sleep cycle.
Researchers at the University of Plymouth have successfully used transcranial ultrasound stimulation (TUS) to change the function of a deep region of the human brain, specifically the nucleus accumbens. This tiny element is triggered by enjoyable experiences and helps us learn behaviours that lead to rewards.
Researchers found a significant link between longer screen time and increased ADHD symptoms, as well as developmental abnormalities in brain structure. The study suggests that excessive screen exposure may contribute to delayed brain maturation patterns in children with ADHD.
Researchers propose a closed-loop system combining peripheral nerve stimulation (PNS) with brain-computer interfaces (BCIs) to personalize neuromodulation. This approach aims to address treatment-resistant depression and schizophrenia by dynamically tailoring interventions to individual neural signatures.
Researchers found that L-DOPA increased participants' willingness to wait for larger delayed rewards by 20%, decreasing impulsivity. The study also suggests that dopamine's effect on waiting may not stem from changes in basic decision processes, but rather from future reward valuation.
A study of 40 women with PTSD following recent sexual assault trauma found a marked reduction in brain synchronization between the amygdala and prefrontal cortex. This disruption may be a biological signature of the disorder rather than a state-dependent marker, potentially leading to personalized treatment response.

The multi-region brain organoid retained a broad range of neuronal cell types and formed electrical activity, allowing for real-time study of neurodevelopmental disorders.
A study by Kobe University found that optimists' brains work similarly when imagining future events, while pessimists' brains show more individuality. This commonality may explain why optimists are seen as more sociable and satisfied with their social relationships.
A specific group of neurons in the amygdala has been identified as a key player in anxiety, depression, and altered social behavior. Restoring balance to this area can reverse these behaviors in mice.
Researchers suggest that brains reach a critical state to learn, remember, and think, which can be measured using fMRI technology. This framework offers a new perspective on neurological diseases like Alzheimer's, which disrupt the brain's ability to maintain criticality.
A global roadmap aims to incorporate biological measurements in psychiatric diagnoses over the next 15-20 years, improving accurate treatment for patients. Current diagnostic methods rely on subjective responses and can be vague, leading to misdiagnosis and ineffective treatments.
A study found that children whose mothers experienced Superstorm Sandy during pregnancy showed distinct brain differences that could affect their emotional development. Prenatal exposure to extreme heat and climate events rewrote critical emotion regulation centers in the developing brain.

The study, led by Jayakrishna Ambati, analyzed data from two large health insurance databases and determined a significant reduction in Alzheimer's risk among patients on NRTIs.
A recent study by Edith Cowan University has found a significant association between excess weight and long-term neurological and mental health symptoms after COVID-19. The researchers suggest that this link could be due to an exaggerated inflammatory response linked to fat tissue, which may store the virus and increase its spread.
A study published in Alzheimer's & Dementia found that learning one's Alzheimer's risk can decrease negative emotions like depression and anxiety, but also leads to decreased motivation for maintaining healthy lifestyle changes. Researchers emphasize the importance of personalized disclosure processes to sustain healthy behaviors.
Previous depression survivors exhibit reduced motivation for everyday tasks but become equally motivated with large and certain rewards. This research sheds light on subtle motivational deficits persisting in recovered depression, guiding targeted treatment for sustained recovery.
A study by Japanese researchers found that individuals with autism have impaired macrophage function, which may contribute to synaptic pruning deficits. The impaired function is associated with lower expression of the CD209 gene, suggesting a molecular mediator for this process.
