    Bipolar I Disorder is defined by manic episodes that last at least seven days, or severe manic symptoms that require immediate hospitalization. Depressive episodes occur as well and usually last at least two weeks. Bipolar I Disorder patients may also have mixed episodes with both manic and depressive symptoms simultaneously.

    Bipolar II Disorder is characterized by a pattern of depressive episodes and hypomanic episodes. Hypomanic episodes have some features of typical manic episodes, but are not severe enough to be considered manic.

    Efficacy Of Lamotrigine: Dysfunction Of Neural Network In Bipolar Depression

    The detailed investigations in the study showed that anticonvulsant activity of the antiepileptic drugs such as lamotrigine and valproic acid is conferred to the inhibition of the brain activation caused by the reduced excitability of the motor cortex induced by TMS stimulation. However, lamotrigine exerts a different action in the prefrontal corticolimbic system on TMS stimulation which shows that lamotrigine differs from valproic acid in molecular mechanisms of action as increased TMS-induced BOLD response was observed in corticolimbic circuits when TMS was applied over the dorsolateral prefrontal cortex . This contrasting neurological effects of lamotrigine on the excitability of prefrontal and motor circuits shows some relevance to the drugs efficacy in the treatment of bipolar disorder and epilepsy respectively . Thus, lamotrigine, anticonvulsant drug, was found to exert a positive effect on the activity of the corticolimbic circuits in patients with bipolar disorder.

    Who Can Take Lamotrigine For Bipolar Disorder

    Epilepsy

    Doctors may prescribe lamotrigine to adults or adolescents who are otherwise being treated for bipolar disorder or weaning off other medications used to treat bipolar disorder. Older adults may be more sensitive to the effects of lamotrigine and prescribed lower doses. When people respond to lamotrigine, they often say they can see things in perspective better and are less reactive under stress. They usually still have days of depression, but these tend to be shorter and less frequent, says Dr. Aiken.

    Children under age 18 are at higher risk of developing a skin rash from lamotrigine if dosed too rapidly. In spite of the potential side effects, however, Dr. Goldberg points out that many studies support the use of lamotrigine for treating bipolar disorder in youth.

    Definitive information about the safety of lamotrigine in pregnancy is not available, as there are no adequate studies in a pregnant woman population, but according to Dr. Goldberg, many doctors perceive it to be among the safer options when treatment benefit outweighs risk to the fetus, especially in women who are more prone to depression than mania. Like many psychotropic drugs, lamotrigine is secreted into breast milk, so women are advised to discuss with their doctors the risk and benefits of breastfeeding while taking lamotrigine.

    Lamotrigine is not recommended in patients who have demonstrated hypersensitivity to the medication or any of its ingredients.

    Bipolar Disorder In Bipolar I Disorder

    Efficacy of lamotrigine was evaluated in subjects with bipolar I depression in a double-blind, parallel-group, multicenter trial . In this study, lamotrigine 50 mg/d , lamotrigine 200 mg/d , or placebo were given to the patients showing 17-item HDRS score 18. After 7 weeks of treatment, primary measures were not significantly different secondary measures, had a significantly superior response rate on mean ± SD observed scores on 17-item HDRS, CGI-Severity of Illness, and CGI-Improvement in lamotrigine 200 mg/d group. In the four other studies subjects diagnosed with bipolar I disorder were treated with lamotrigine 200 mg/d or placebo. 17-item HDRS total scores or the MADRS was not significantly different in treated or placebo, with the exception of 1 trial . However, CGI-Improvement score was significantly greater with lamotrigine treated group in two studies . suggested that sufficient evidence are not available to recommend use of lamotrigine in the treatment of rapidly-cycling bipolar I.

    A Fifth Type Of Medication That Affects Brain Function

    Opiate pain medications. Unlike the other drugs mentioned above, opiates are not on the Beers list of medications that older adults should avoid. That said, they do seem to dampen thinking abilities a bit, even in long-term users. As far as I know, opiates are not thought to accelerate long-term cognitive decline.

    • Commonly prescribed opiates include hydrocodone, oxycodone, morphine, codeine, methadone, hydromorphone, and fentanyl.
    • Tramadol is a weaker opiate with weaker prescribing controls.
    • Many geriatricians consider it more problematic than the classic Schedule II opiates listed above, as it interacts with a lot of medications and still affects brain function. Its a dirty drug, as one of my friends likes to say.
  • Alternatives depend on what type of pain is present. Generally, if people are taking opiates then they have pain that needs to be treated. However, a thoughtful holistic approach to pain often enables a person to get by with less medication, which can improve thinking abilities.
  • For people who have moderate or severe dementia, its important to know that untreated pain can worsen their thinking. So sometimes a low dose of opiate medication does end up improving their thinking.
  • Other risks in older adults:
  • There is some risk of developing a problematic addiction, especially if theres a prior history of substance abuse. But in my experience, having someone else usually younger steal or use the drugs is a more likely problem.

    Why Is This Medication Prescribed

    Pharmacology – ANTIEPILEPTIC DRUGS (MADE EASY)

    Lamotrigine extended-release tablets are used with other medications to treat certain types of seizures in patients who have epilepsy. All types of lamotrigine tablets other than the extended-release tablets are used alone or with other medications to treat seizures in people who have epilepsy or Lennox-Gastaut syndrome . All types of lamotrigine tablets other than the extended-release tablets are also used to increase the time between episodes of depression, mania , and other abnormal moods in patients with bipolar I disorder . Lamotrigine has not been shown to be effective when people experience the actual episodes of depression or mania, so other medications must be used to help people recover from these episodes. Lamotrigine is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain.
