Fluoxetine, the antidepressant commonly known as Prozac, may be beneficial for the treatment of age-related macular degeneration. Researchers found Prozac significantly slowed the rate at which people over 50 developed AMD.
Prozac reduced polyunsaturated fatty acid lipid concentrations in the brains of juvenile macaque monkeys.
Long-term circadian rhythm disruptions induce Alzheimer's disease-like pathology in rats, which can be reversed by administering fluoxetine. Additionally, elevated levels of amyloid beta and circadian rhythm disruptions can trigger each other, leading to the cascade of neurological symptoms of dementia.
Alteration of placental serotonin levels due to maternal depression or antidepressant use may be associated with the disruption of placental estrogen production.
Exposure to antidepressants during the first few weeks of pregnancy has long term implications for sensory processing in the offspring.
Serotonin and SSRIs like Prozac can have a major effect on gut bacteria. When exposed to serotonin, specific gut bacteria grew to higher levels. However, when exposed to SSRIs, the bacterium grew to much lower levels in mouse models.
Fluoxetine rearranges nerve fibers in the hippocampus of mice, a new study reports.
SSRI antidepressants, such as Prozac and Paxil, interact with opioid medications to make them less effective at providing relief from chronic pain. Tramadol relies on activation of the CYP2D6 enzyme to control pain, but SSRIs inhibit this enzyme. Researchers suggest prescribing different classes of antidepressants which do not suppress the enzyme may benefit those in need of opioid medications. Alternatively, non-opioid pain killers should be considered for those who can not switch from SSRIs.
A new study in mice reveals a possible link between the use of SSRI antidepressants during pregnancy and an increased risk of autism-like symptoms in offspring. Offspring exposed to fluoxetine (Prozac) in utero were more likely to exhibit impaired neurotransmission caused by an overactive serotonin receptor in the prefrontal cortex, an area of the brain implicated in modulating social behaviors. However, treating the mice with a compound that blocks the receptor alleviated the behavioral problems and improved working memory.
A new study reports male songbirds sing less to females during courtship if they have been exposed to low levels of SSRI antidepressants.
Researchers have developed an enhanced imaging technique that can detect small fluctuations in the rate at which neurons are generated in the brain.
Researchers report inducing a second stroke may increase brain plasticity.
