Pathology News and Research

RSS

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called General pathology. Medical pathology is divided in two main branches, Anatomical pathology and Clinical pathology. Veterinary pathology is concerned with animal disease whereas Phytopathology is the study of plant diseases.

Study reveals complex relationship between alcohol and Alzheimer's disease

Alcohol use has been associated with an increased risk of cognitive decline and dementia. But new research from the Texas A&M University Naresh K. Vashisht College of Medicine at Texas A&M Health suggests the relationship between alcohol and Alzheimer's disease is more complicated than previously thought.

Study identifies new target for Parkinson's disease neuroprotection

Parkinson's disease (PD) is the second most common form of neurodegenerative disease and afflicts more than ten million people worldwide. While current therapies address disease symptoms, they do not prevent the underlying neurodegeneration that drives the disease.

Modern IVF treatment boosts live births while lowering twin pregnancies

Modern IVF treatment can now achieve substantially higher success rates than historical approaches while dramatically reducing twin and triplet pregnancies, according to new research presented today at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE).

New review shows why antidepressants often fail in Alzheimer’s and Parkinson’s depression

A Molecular Psychiatry review shows that depression in Alzheimer’s and Parkinson’s disease may reflect disease-specific molecular, neurotransmitter, inflammatory, and circuit-level disruptions rather than standard depression biology alone. It argues that broad antidepressants often show limited efficacy in these patients and that future trials should use biomarkers, neuroimaging, and symptom profiling to guide targeted treatments.

New artificial intelligence model reveals invisible multiple sclerosis lesions

One of the uncomfortable truths about multiple sclerosis is that the part of the brain likely to reveal the most about the disease and how a patient will be impacted has been mostly invisible to clinicians.

Study compares different light therapies for treating Alzheimer's disease

The researchers treated 5‑month‑old 5xFAD mice – a model with aggressive amyloid deposition – with 810‑nm light (25 mW/cm² at the scalp, ~6.25 mW/cm² brain dose for CW, and half that for 40‑Hz due to 50% duty cycle) for 10 minutes daily over 37 days.

BCG vaccine may remodel the human brain's immune environment

New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine - which is delivered through the skin to prevent tuberculosis - may remodel the human brain's immune environment, offering a potential biological explanation for previously observed associations between BCG vaccination and lower Alzheimer's disease risk.

Swiping-based dating apps show strongest ties to compulsive use and body dissatisfaction

A meta-analysis of 27 studies involving 21,263 adults linked swiping-based dating app use to small-to-moderate adverse mental health correlates, especially compulsive use, body image concerns, and appearance-related anxiety. General well-being was not significantly associated with app use in the primary analysis, and the authors stressed that mostly cross-sectional evidence cannot prove causality.

Researchers uncover shared olfactory mechanisms across mice and humans

Picture a mouse taking rapid, staccato sniffs of a crumb it's found while foraging for food. Now compare that with a human, leaning in for a single, deep inhale to gauge if a cantaloupe is ripe.

Experimental drug shields nerve cells from damage caused by ALS

Amyotrophic Lateral Sclerosis, or ALS, received widespread awareness in the summer of 2014 thanks to an Ice Bucket Challenge. Millions of people participated in the challenge, drenching themselves in ice cold water to bring visibility to this devastating neurodegenerative disease and generate charitable donations for research.
