Serotonin Deficiency Accelerates Memory Loss in Early Alzheimer's

Lower levels of serotonin, the "happiness" chemical, have been linked to memory decline in individuals with mild cognitive impairment (MCI), potentially advancing our understanding of Alzheimer's Disease (AD). A study found that people with MCI had significantly reduced serotonin transporter levels, which may contribute to memory problems and disease progression. Targeting serotonin levels could offer new avenues for treatment and early intervention. However, further research is needed to explore the role of serotonin in transitioning from MCI to AD.
