  1. Mood-stabilizing drugs are the most widely prescribed pharmacological treatments for bipolar disorder, a disease characterized by recurrent episodes of mania and depression. Despite extensive clinical utilization, significant questions concerning their mechanisms of action remain. In recent years, a diverse set of molecular and cellular targets of these drugs has been identified
  2. Moreover, the presence of neuroplasticity in the prefrontal cortex (Mulder et al., 1997;Williams and Goldman-Rakic, 1995) also suggests the possibility that this structure participates in the memory storage functions of all three systems (White and McDonald, 2002). Interestingly, antiepileptic treatment with valproic acid (VPA) is able to.
  3. This approach has been taken with lithium and valproic acid, yielding the hypothesis that a dysfunction of neuroplasticity and cellular resilience may be a central component of the disorder [1,2], with a range of molecular targets identified [3,4]

Neuroplasticity, including dendritic remodelling, synapse turnover, long-term potentiation (LTP), and neurogenesis, is a feature of the brain's response to the environment. Acupuncture - as one of the complementary therapies - is widely used by physicians in clinical practice. Although many studies have tried to analyse the potential effects. These include hormonal birth control methods, hormone treatments, seizure medications such as phenobarbital, and valproic acid, which is also used to treat bipolar disorder. Your doctor will carefully prescribe and monitor your dosage when lamotrigine is taken with other treatments. Avoid alcohol, cannabis, and other substances that can. Studies of neurons from ASD patients as well as our previous results obtained from the valproic acid (VPA)-induced rat model of ASD revealed ultrastructural and molecular alterations in synapses as well as morphological abnormalities within dendrites, axons, dendritic spines, and in the organization of the neural network [15,16,17,18,19], which.
