Alzheimer’s Study Identifies 16 Risk Genes
Summary: A large whole-genome sequencing study has uncovered 16 new genes linked to Alzheimer’s disease, expanding genetic research beyond European ancestry. Researchers analyzed data from 49,149 individuals, nearly half of…
Schizophrenia Symptoms Linked to Unique Brain Structures
Summary: A new international study reveals that schizophrenia manifests differently in the brain, reflecting the wide range of symptoms among patients. Researchers analyzed imaging data from over 6,000 individuals and…
SSRIs May Speed Up Cognitive Decline
Summary: A new study based on data from 18,740 dementia patients suggests that antidepressants may accelerate cognitive decline. Researchers found that patients taking antidepressants, particularly SSRIs like escitalopram, citalopram, and…
Low-Normal B12 Levels Linked to Slower Brain Processing
Summary: Even when within the normal range, lower levels of vitamin B12 may contribute to cognitive decline, according to a new study. Researchers found that older adults with lower biologically…
Genetic Mutation Linked to Schizophrenia Alters Brain Function
Summary: Researchers identified a rare genetic mutation in two schizophrenia patients that increased schizophrenia-related behaviors in mice. The mutation led to higher levels of glycine decarboxylase (GLDC), an enzyme that…
