Antibiotic treatments can affect the composition of the community of bacteria living in the gut, known as the gut microbiome, for a long time.

A certain blood protein regarded as an early indicator of Alzheimer's disease also appears to play a role in other disorders.

Low testosterone in itself can cause a variety of health problems, but the addition of a poor diet can exacerbate certain conditions. Metabolic dysfunction-associated steatotic liver disease (MASLD) is one example that approximately 40% of adult men worldwide currently suffer from and has become a global problem.

Drug addiction carries an extremely high risk of relapse, as cravings can be reignited by minor stimuli even long after one has stopped using.

A study in Economic Inquiry reveals how total abortion bans are reshaping public health systems and safety‐net programs in the United States.

Rapid Novor Inc., a Canadian biotechnology leader, announced today that its diagnostic laboratory has received a provisional license from the Ontario Ministry of Health (MOH) for its EasyM® assay, enabling the company to begin testing patients in Canada.

Cannabis and other illicit drugs are associated with higher stroke risk, underscoring the importance of addressing substance use disorders in health strategies.

This educational game simulates breastfeeding complications, equipping nurses with skills to detect and manage fungal infections in the nipple-areola area.

A study reveals COVID-19 reshaped stimulant prescribing patterns in Ontario, highlighting increased ADHD diagnoses and concerns over treatment appropriateness.

Artificial intelligence (AI) is changing the field and practice of medicine, including legal liability and the perception of who is at fault when a patient experiences harm.

Motor imagery (MI) is the mental process of imagining a specific limb movement, such as raising a hand or walking, without physically performing it. These imagined movements generate distinct patterns of brain activity that can be recorded using electroencephalography (EEG).

Critical Path Institute® (C-Path) applauds the publication of a new study in the Journal of Neurology that offers critical longitudinal insights into how symptoms and functional impacts evolve for individuals with early Parkinson's disease (PD).

An insightful mini-review published in Genomic Psychiatry synthesizes the rapidly expanding landscape of molecular genetic research on common epilepsies, assembling evidence from genome-wide association studies, whole-exome sequencing projects, and advanced statistical modeling to illuminate the polygenic architecture that underpins these heterogeneous neurological disorders.

Miniature organs grown in the lab can organize themselves into complex shapes. But they never do it the same way twice, which makes it hard to use these so-called 'organoids' to study disease.

Wegovy, a GLP-1 agonist for weight loss, may carry the highest risk of 'eye stroke' (ischemic optic neuropathy) and sudden sight loss of the semaglutide drugs, finds an analysis of unintended side effect reports published in the British Journal of Ophthalmology.
