How beliefs about demons shape the experience of mental illness

For some evangelical Christians, attributing mental illness to demonic forces can offer a sense of meaning, while for others, it creates harmful barriers to medical care. A recent qualitative study published in Spirituality in Clinical Practice outlines how these widespread spiritual explanations act as a double-edged sword for individuals experiencing psychological distress. The research indicates that integrating religious beliefs with standard psychiatric care may be a safer path forward for many faith communities.

Religion frequently shapes how people interpret their physical and mental health. Psychologists recognize that religious frameworks offer a primary system for individuals to make sense of the world around them. By relying on theological teachings, people construct meaning around their personal suffering. This process of religious meaning construction can influence health outcomes in both positive and negative directions.

Within evangelical Christianity, foundational teachings often emphasize the active existence of spiritual forces. This includes the belief that angels, demons, and other supernatural entities directly influence the physical world. This worldview can lead to the belief that spiritual forces cause human ailments, including severe psychological distress.

Demon face syndrome: The science behind prosopometamorphopsia

Imagine looking at a loved one and seeing their face twist into a demonic, unnatural shape. Their eyes might stretch to the sides of their head, their nose might swell, and deep, unnatural grooves might appear across their cheeks and forehead. This terrifying visual experience belongs to a rare neurological condition known medically as

In popular media and online discussions, it is sometimes referred to as “demon face syndrome.” People with this condition see human faces as severely distorted, even though their vision for everyday objects remains completely normal.

Prosopometamorphopsia is fundamentally different from a hallucination. A hallucination involves seeing something that is not actually present in the physical world. People experiencing these facial distortions are looking at a real person standing in front of them. Their brain simply alters the shape, size, color, or position of the facial features before the image reaches their conscious awareness.

Zebrafish reveal new insights into the biology of autism

In recent decades, the zebrafish has become one of the most valuable model organisms in scientific research. For a variety of reasons, including their genetic similarities to humans, these tiny tropical fish have helped researchers unlock secrets to diseases ranging from muscular dystrophy to melanoma. Now, Yale researchers are hoping the zebrafish will do the same for autism spectrum disorder.

In a new study, a research team generated a database of 520 U.S. Food and Drug Administration (FDA)-approved drugs and their effects on basic larval zebrafish behaviors and then used the database to identify drug candidates that reverse disrupted behaviors in zebrafish carrying mutations in autism risk genes.

These drug candidates, the researchers say, might represent targets for people carrying mutations in specific autism risk genes.

Transcranial magnetic stimulation can target a deep brain region without surgery or medication

Neuroscientists at University of Iowa Health Care have demonstrated for the first time that noninvasive brain stimulation can alter the activity of a critical deep brain region involved in emotion and memory. Moreover, the study shows that personalizing the stimulation site using a patient’s unique brain connectivity pathway can increase the neuromodulation effect.

The study, published recently in Nature Communications, used innovative, concurrent brain stimulation and recording techniques in people to provide direct human evidence that noninvasive transcranial magnetic stimulation (TMS) can reliably engage and modulate activity in the hippocampus.

The hippocampus is a deep brain region that plays a critical role in multiple brain functions, such as memory and emotion. Problems with hippocampal function have been implicated in several neurological and neuropsychiatric conditions, including Alzheimer’s disease, depression, anxiety, and post-traumatic stress disorder (PTSD).

Association of White Matter Hyperintensities, Regional Brain Glucose Metabolism, and Cognitive Impairment in Aβ-Negative Patients

This study examined whether periventricular white matter hyperintensities relate to region-specific cortical hypometabolism and metabolism mediates domain-specific cognition in Aβ-negative individuals.

Cytomegalovirus Drives the Development of Cytotoxic CD4+ T Cells in Patients With Multiple Sclerosis

Background and ObjectivesChronic immune activation is a hallmark of latent viral infections and autoimmune disorders, profoundly shaping immune cell phenotypes, including CD4+ cytotoxic T lymphocytes (CD4 CTL). The mechanisms underlying CD4 CTL…

New sensor could allow MRIs to see molecular-level changes

You’ve seen people sliding into the tube of a magnetic resonance imaging (MRI) machine on your favorite medical drama, or maybe you’ve been inside one yourself, waiting as the noisy scanner makes images of your brain, heart, bones, or other structures, which doctors use to identify injury or disease.

Since the 1970s, MRIs have been important diagnostic tools, combining a magnetic field and radio waves to produce snapshots of the body’s interior without using ionizing radiation, which can create health risks at higher doses. An MRI can typically capture changes in anatomy, but the molecular-level changes that could further aid understanding of disease have been beyond its reach.

Now, in a new article in Science Advances, University of California, Santa Barbara researchers report the invention of a modular, genetically encoded, protein-based sensor that enables MRI machines to visualize molecular activity inside cells—a development that could transform how scientists study cancer, neurodegeneration, and inflammation.

The neuroscience of hypocrisy points to a communication breakdown in the brain

Half of the participants received actual stimulation aimed at the ventromedial prefrontal cortex. The other half received a fake version of the treatment, known as a sham stimulation. After the procedure, all participants completed the same card game and judgment exercises.

The people who received the real brain stimulation showed a wider gap between their behavior and their judgments. By disrupting the normal function of the brain region, the researchers successfully made people more hypocritical. This proved that the ventromedial prefrontal cortex directly controls moral consistency.

These results suggest that moral consistency is not an automatic trait. It is a biological process that relies on the brain’s ability to sync up different types of information. “Our findings suggest that we should treat moral consistency like a skill that can be strengthened through deliberate decision making,” says senior author Hongwen Song of the University of Science and Technology of China.

Chemokines CXCL9 and CCL2 in Relation to Cerebral White Matter Disease, Cognitive Decline, and DementiaThe Northern Manhattan Study

This large cohort study showed that higher serum CXCL9 was associated with greater burden of white matter disease in the brain, independent of vascular risk factors, renal function, and genetic predisposition, supporting a role for CXCL9 in white matter pathogenesis.

Background and Objectives.
