What happens to your brain on lithium?
Lithium acts on a person’s central nervous system (brain and spinal cord). Doctors don’t know exactly how lithium works to stabilize a person’s mood, but it is thought to help strengthen nerve cell connections in brain regions that are involved in regulating mood, thinking and behavior.
Where does lithium act in the brain?
Interestingly, lithium appears to preserve or increase the volume of brain structures involved in emotional regulation such as the prefrontal cortex, hippocampus and amygdala, possibly reflecting its neuroprotective effects.
What exactly does lithium do?
Lithium is a type of medicine known as a mood stabiliser. It’s used to treat mood disorders such as: mania (feeling highly excited, overactive or distracted) hypo-mania (similar to mania, but less severe)
Does lithium improve brain function?
While lithium may seem like a simple element, it has complex effects on the brain at many different levels: Neuroprotection: Lithium shields neurons from biological stress and toxins. Neurogenesis: Lithium enhances the growth of new neurons, leading to increased number of neurons and brain volume.
Does lithium protect the brain?
It also protects brain neurons by controlling cellular pathways, such as those involved in oxidative stress (where the brain struggles to control toxins) and inflammation. Animal studies have shown that long-term treatment with lithium leads to improvement in memory and learning.
How mood stabilizers work in the brain?
How do mood stabilizers work? Mood stabilizers work by decreasing abnormal activity in the brain. These medications can help reduce mood swings and prevent manic and depressive episodes.
Does lithium increase BDNF?
The preservation of cognitive function in humans with bipolar disorder seems to occur through the brain-derived neurotrophic factor (BDNF) system: lithium markedly increases secretion of BDNF from cortical and hippocampal neurons and upregulates intracellular production of relevant proteins.
Why do bipolar patients stop taking lithium?
Adverse effects were the most common cause for lithium discontinuation. Among the adverse effects, diarrhoea, tremor, creatinine increase, polyuria/polydipsia/diabetes insipidus and weight gain were the top five reasons for discontinuing lithium.
How do you know lithium is working?
A reduction in manic symptoms should be noticed within 5 to 7 days but the full therapeutic effect may require 10 to 21 days. Lithium concentrations should be determined immediately before the next dose (ie, 8 to 12 hours after the previous lithium dose).
Can taking lithium cause memory loss?
Lithium has been associated with impaired memory, word finding difficulties, and impaired recall. Often, my patients have reported a cognitive “dulling” and a loss of cognitive “creativity” with lithium use that they found most disturbing.
Does lithium help memory?
In research settings, lithium appears to have virtually no effect on concentration or on short- or long-term memory, but it does have modest effects on psychomotor speed, verbal memory, and verbal fluency.
What is the function of lithium in the brain?
Lithium also increases brain concentrations of the neuronal markers n-acetyl-aspartate and myoinositol. Lithium also remarkably protects neurons against glutamate, seizures, and apoptosis due to a wide variety of neurotoxins.
How effective is ledlithium for bipolar disorder?
Lithium is a mood stabilizer that can be helpful with bipolar disorder and other conditions but is well known for causing side effects and toxicity. That said, when tests are performed regularly to monitor levels, and people are familiar with the proper use of the drug, it can be very effective in controlling moods.
How does lithium affect PKC levels in the brain?
During mania increased PKC activity has been found. Acute treatment with lithium has shown to activate PKC levels, and over longer periods lithium down regulates PKC and subsequently substrate MARCKS in the hippocampus. This is likely responsible for its neuroprotective effect.
What are the effects of lithium toxicity?
Serum lithium levels of 1.5-2.0 mM may have mild and reversible toxic effects on kidney, liver, heart, and glands. Serum levels of >2 mM may be associated with neurological symptoms, including cerebellar dysfunction. Prolonged lithium intoxication >2 mM can cause permanent brain damage.
