Low Serotonin in Brain May Explain Cognitive Impairment, Johns Hopkins Study Shows
Johns Hopkins researchers looked at brain scans and discovered that lower levels of the neurotransmitter serotonin underlie the mild loss of cognitive functions that usually precede the onset of Alzheimer’s disease. These findings suggest that preventing the loss of serotonin could halt or even prevent the progression of Alzheimer’s disease and potentially other dementias. The study, “Molecular imaging of serotonin degeneration in mild cognitive impairment,” was published in the journal Neurobiology of Disease. "Now that we have
