New study reveals hidden manic symptoms in one-fourth of schizophrenia patients

Pivotal research identifies crucial link between positive symptoms and mania in schizophrenia spectrum disorders

2025-02-11

(Press-News.org) THESSALONIKI, Greece, 11 February 2025 - In a notable Genomic Press research report, researchers at the Aristotle University of Thessaloniki have uncovered a significant presence of manic symptoms in patients with schizophrenia spectrum disorders (SSDs), offering valuable insights that could reshape treatment approaches.

The rigorous peer-reviewed study, published in Brain Medicine, examined 75 stable outpatients with SSDs, revealing that more than one in four patients (26.7%) exhibited distinct manic symptoms, a finding that carries important implications for clinical practice and patient care.

"Our research demonstrates a clear association between positive symptoms and manic presentations in schizophrenia spectrum disorders," explains Professor Evangelia M. Tsapakis, lead researcher of the study. "More importantly, we found that the severity of positive symptoms could predict the presence of manic symptoms, suggesting a deeper connection between these two aspects of psychopathology."

The investigation utilized the Young Mania Rating Scale (YMRS) alongside other clinical assessment tools, finding that patients with higher scores on the Positive and Negative Syndrome Scale (PANSS) were more likely to experience manic symptoms. This correlation proved particularly strong for positive symptoms, such as hallucinations and delusions.

"Our findings suggest we may need to reevaluate how we screen for and treat schizophrenia spectrum disorders," notes Professor K.N. Fountoulakis, senior author of the study. "By identifying manic symptoms early through systematic screening, we could potentially improve treatment outcomes and reduce the economic burden on both patients and healthcare systems. This is particularly relevant for patients who may not be responding optimally to current treatment approaches."

The study's findings support a more nuanced, dimensional understanding of mental health conditions rather than strict categorical diagnoses. This perspective could lead to more personalized treatment strategies and improved patient outcomes.

The research also revealed that:

The presence of manic symptoms significantly correlated with overall clinical psychopathology Language and thought disorders showed strong associations with manic presentations Current diagnostic approaches might be overlooking important manic components in SSD patients These discoveries raise important questions about the current diagnostic framework and treatment approaches. Could the presence of manic symptoms indicate a distinct subtype of schizophrenia? Might some patients benefit from mood-stabilizing medications in addition to traditional antipsychotic treatments?

The research team suggests that implementing regular screening for manic symptoms in SSD patients could lead to more effective, personalized treatment approaches. This recommendation comes at a crucial time when healthcare systems worldwide are seeking more cost-effective and efficient treatment strategies.

Does the universe behave the same way everywhere? Gravitational lenses could help us find out

2025-02-11

“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of the new paper. According to the Cosmological Principle, not only are we not at the center of the Universe, but a true center does not exist. A further assumption, similar to but distinct and independent from homogeneity, is that the Universe is also isotropic, meaning it has no preferred directions. These assumptions underlie the Standard Model of Cosmology, the theoretical ...

Majority support moderation on social media platforms

2025-02-11

Most people want harmful social media content such as physical threats and defamation to be restricted. This also applies in the USA where several social media platforms have recently modified their policies in favor of unrestricted free speech. However, the majority of users believe that intolerance and hate have become unavoidable on social media. This was revealed in a large-scale survey conducted by the Technical University of Munich (TUM) and the University of Oxford in 10 countries in Europe, America, Africa and Australia. The study also highlights differences among countries. The global debate on whether and how social media content should ...

Born too late? Climate change may be delaying births

2025-02-11

New Curtin University research has found exposure to outdoor air pollution and extreme temperatures during pregnancy may increase the risk of prolonged pregnancy, offering new insights into the impact of climate change on maternal health. The study analysed data from nearly 400,000 births in Western Australia and found that higher exposure to fine particulate air pollution (PM2.5) and biothermal stress (a measure that combines air temperature, radiant temperature, relative humidity, wind speed, and human physiology) was associated ...

Truly autonomous AI is on the horizon

2025-02-11

Researchers have developed a new AI algorithm, called Torque Clustering, that is much closer to natural intelligence than current methods. It significantly improves how AI systems learn and uncover patterns in data independently, without human guidance. Torque Clustering can efficiently and autonomously analyse vast amounts of data in fields such as biology, chemistry, astronomy, psychology, finance and medicine, revealing new insights such as detecting disease patterns, uncovering fraud, or understanding behaviour. “In nature, animals learn by observing, exploring, and interacting with their ...

California’s marine protected areas boost fish populations across the state

2025-02-11

(Santa Barbara, Calif.) — It’s 1999, the 21st century is on the horizon, and California has big plans for marine conservation. New legislation has presented a mandate to establish an ambitious network of marine protected areas (MPAs) unlike anywhere else in the world. The goal is to craft strategic protections to safeguard the state’s marine life for preservation and economic benefits alike. Now 25 years later, an international team of researchers, led by scientists at UC Santa Barbara, have evaluated the network’s ...

The study is the first to use social media as a tool for assessing illegal hunting activities in Lebanon. The country, along with the Mediterranean region more broadly, is a global poaching blackspot, particularly for the illegal killing of protected ...

Examining the potential environmental effects of mining the world’s largest lithium deposit

2025-02-11

DURHAM, N.C. -- The world’s largest known lithium deposit exists within a vast salt pan called the Salar de Uyuni, which stretches for thousands of square miles atop a high, dry Andean plateau in Bolivia. For most of the year, salt crystals encrust the terrain, white as confectioner’s sugar. During the wet season, pooling rainwater mirrors surrounding mountains and sky. “The Salar is a magical place for travelers from all over the world who come to see the colors, the reflections, in this endless white landscape,” said Avner Vengosh, Nicholas Chair of Environmental Quality at the Duke University ...

Chicken ‘woody breast’ detection improved with advanced machine learning model

2025-02-11

FAYETTEVILLE, Ark. — It’s called “woody breast” and for consumers it can mean a chewier chicken sandwich, but for the industry it can mean up to $200 million annual yield loss. Work done by the Arkansas Agricultural Experiment Station is not only making woody breast easier to detect in chicken meat but is accurate up to 95 percent of the time. The development could help improve quality assurance and customer confidence in one of the state’s most economically important agricultural products. What allows ...

Around 1 in 5 UK medical students considers dropping out, study suggests

2025-02-11

Around 1 in 5 UK medical students considers dropping out of medical school, with mental health issues a key contributor to their intention to abandon medicine, suggest the results of an observational study published in the open access journal BMJ Open. The shortage of doctors worldwide is a major cause for concern, say the researchers, with the current shortfall thought to be around 6.5 million. These shortages not only affect the quality of patient care, but also doctors’ wellbeing as a result of increased workload and chronic stress, which further undermine recruitment and retention, creating a vicious circle, they add. Given that medical ...
